Smartflash LLC v. Apple Inc. (77 F. Supp. 3d 535, 2014)

JURY TRIAL DEMANDED

ORDER ADOPTING REPORT AND

RECOMMENDATION OF UNITED STATES MAGISTRATE JUDGE

MICHAEL H. SCHNEIDER, UNITED STATES DISTRICT JUDGE

The above entitled and numbered civil action was referred to United States Magistrate Judge K. Nicole Mitchell pursuant to 28 U.S.C. § 686. The Report and Recommendation of the Magistrate Judge (“R & R”), which recommends adoption of the Court’s claim construction and denial of Defendants’ Motions for Summary Judgment for Invalidity, has been presented for consideration (6:13cv447, Doc. No. 229; 6:13cv448, Doc. No. 270). Defendants filed objections (6:13cv447, Doc. No. 251; 6:13cv448, Doc. Nos. 303, 304) to the R & R.

Defendants’ objections assert that the R & R violated the “Federal Circuit’s clear directions” by not applying 35 U.S.C. § 112, ¶ 6 to apparatus claims reciting the word “processor.” 6:13cv448, Doc. No. 304 at 2 (citing Aristocrat Techs. Austl. PTY Ltd. v. Int’l Game Tech., 521 F.3d 1328 (Fed.Cir.2008) (holding that under § 112, ¶ 6, a “control means” claim limitation was indefinite because the patent did not disclose an algorithm); Noah Sys. Inc. v. Intuit Inc., 675 F.3d 1302 (Fed.Cir.2012) (holding that under § 112, ¶ 6, an “access means” claim limitation was indefinite because the patent disclosed an algorithm that failed to enable one skilled in the art)); see also 6:13cv447 Doc. No. 251 at 5. Additionally, Defendants point out that the R & R did not address the Personal Audio case from this District that construed limitations reciting a “processor” as means plus function claims subject to § 112, ¶ 6. 6:13cv448, Doc. No. 304 at 2; 6:13cv447, Doc. No. 251 at 5; Personal Audio, LLC v. Apple, Inc., No. 9:09-cv-111, 2011 WL 11757163 (E.D.Tex. Jan. 30, 2011). The Court addresses Federal Circuit guidance on this issue and the Personal Audio case below.

Federal Circuit Guidance

Section 112, ¶60«^ § 112(f)) allows a patentee to claim a “means or step for” a function without reciting structure to support that function, but the “claim shall be construed to cover the corresponding structure ... described in the specification and equivalents thereof.” Accordingly, “[m]eans-plus-function claiming applies only to purely functional limitations that do not provide the structure that performs the recited function.” Phillips v. AWH Corp., 415 F.3d 1303, 1311 (Fed.Cir.2005). Thus, the court must first determine whether the limitation invokes § 112, ¶ 6. Rodime PLC v. Seagate Tech., Inc., 174 F.3d 1294, 1302 (Fed.Cir.1999). A limitation that actually uses the word “means” raises a rebuttable presumption that § 112, ¶ 6 applies. Lighting World, Inc. v. Birchwood Lighting, Inc., 382 F.3d 1354, 1358 (Fed.Cir.2004). By contrast, when a claim limitation lacks the term “means,” it creates a rebuttable presumption that § 112, ¶ 6 does not apply. Id. “The use of the term ‘means’ is ‘central to the analysis,’ because the term ‘means,’ particularly as used in the phrase ‘means for,’ is ‘part of the classic template for functional claim elements,’ and has come to be closely associated with means-plus-function claiming.” Id. (internal citations omitted).

The presumption that § 112, ¶ 6 does not apply can be “overcome if the claim fails to recite sufficiently definite structure, or else recites function without sufficient structure for performing that function.” Id. (internal citation and quotation marks omitted). However, the Federal Circuit has “repeatedly characterized this presumption as ‘strong’ and ‘not readily overcome’ and, as such, ha[s] ‘seldom’ held that a limitation without recitation of ‘means’ is a means-plus-function limitation.” Apple, Inc. v. Motorola, Inc., 757 F.3d 1286, 1297 (Fed.Cir.2014) (citing Lighting World, 382 F.3d at 1358; Flo Healthcare Solutions, LLC v. Kappos, 697 F.3d 1367, 1374 (Fed.Cir.2012) (“When the claim drafter has not signaled his intent to invoke § 112 ¶ 6 by using the term ‘means,’ we are unwilling to apply -that provision without a showing that the limitation is essentially devoid of anything that can be construed as structure.”)). “The correct inquiry, when ‘means’ is absent from a limitation, is whether the limitation read in light of the remaining claim language, specification, prosecution history, and relevant extrinsic evidence, has süffi-ciently definite structure to a person of ordinary skill in the art.” Id. at 1298.

In computer implemented inventions, one of ordinary skill in the art can understand “structure” through an outline of an algorithm, a flowchart, or set of instructions or rules, rather than traditional physical structure. Id. (citing Typhoon Touch Techs., Inc. v. Dell, Inc., 659 F.3d 1376, 1385 (Fed.Cir.2011) (“[T]he patent need only disclose sufficient structure for a person of skill in the field to provide an operative software program for the specified function.”)). Section 112, ¶ 6 will not apply to terms “used in common parlance of by persons of ordinary skill in the pertinent art to designate structure.” Lighting World, 382 F.3d at 1359. Additionally, the Federal Circuit has held that terms such as “detector” and “circuit” are structural terms while generic terms such as “means,” “element,” and “device” are nonstructural. Apple, 757 F.3d at 1299 (citing Personalized Media Commc’ns, LLC v. Int’l Trade Comm’n, 161 F.3d 696, 705 (Fed.Cir.1998); Apex Inc. v. Raritan Computer, Inc., 325 F.3d 1364, 1373 (Fed.Cir.2003)). Even if a term covers a broad class of structures and identifies structures by their function, it is sufficient to avoid means-plus-function treatment. Lighting World, 382 F.3d at 1360. What is important is whether the term is understood to describe structure and is not simply a substitute for “means for.” Id.

As a preliminary matter, in two cases cited by Defendants as providing clear directions to the Court, Aristocrat and Noah, the asserted claims included the term “means.” There were no disputes that means-plus-function claim construction applied. Thus, neither case analyzed the presumption against the applicability of § 112, ¶ 6 where a claim does not recite “means.”

In Aristocrat, the court determined that the specification’s disclosure for “control means” of a standard microprocessor with appropriate programming did not sufficiently define the scope of the means-plus-function claim. 521 F.3d at 1331, 1338. Noting its clear applicability because the claim explicitly recited “means,” the court applied § 112, ¶ 6, which requires the scope of the claim limitation to be defined by the structure disclosed in the specification plus any equivalents thereof. Id. at 1331. The court noted that “[i]n cases in which the inventor has invoked means-plus-function claiming, this court has consistently required that the structure disclosed in the specification be more than simply a general purpose computer or microprocessor.” Id. at 1333. Additionally, the court stated that allowing the “paten-tee to claim a means for performing a particular function and then to disclose only a general purpose computer as the structure designed to perform that function amounts to pure functional claiming.” Id.; see also Personal Audio, 2011 WL 11757163, at *22.

Defendants’ argument essentially applies Aristocrat in reverse. Defendants argue that because “processor” does not adequately define the scope of a means-plus-function limitation, it also cannot describe sufficient structure to avoid means-plus-function treatment when recited in the claim itself. 6:13cv448, Doc. No. 304 at 2; see also Doc. No. 177-1 ¶¶ 38-45 (asserting “the identified claims fail[ ] to disclose sufficient structure” because “the identified claims do not disclose the specialized algorithms that would be required to enable a general purpose processor to perform any of the claimed high-level functions.”). However, in light of the Federal Circuit’s guidance in Apple, Defendants’ reasoning fails; Aristocrat does not apply here, where the claim is not drafted in means-plus-function format. See 757 F.3d at 1298; see also Wi-Lan USA, Inc. v. Alcatel-Lucent USA, Inc., No. 12-23568-CIV, 2013 WL 4811233, at *40 (S.D.Fla. Sept. 9, 2013). The standard used to prove sufficient structure to avoid means-function-treatment is not identical to the standard for identifying corresponding structure to a means-plus-function claim. See 757 F.3d at 1298; see also Wi-Lan, 2013 WL 4811233, at *40-41. Similarly, Noah does not apply here because it also analyzes the adequacy the specification’s disclosure for defining claim scope where a patentee has explicitly invoked means-plus-function claiming. 675 F.3d at 1314-18. It does not address the standard for overcoming the presumption against means-plus-function treatment. Id.

Defendants’ expert report also fails to address the legal requirements for overcoming the presumption against means-plus-function treatment when the claims themselves do not recite the term “means.” In fact, Defendants’ expert begins with the presumption that the disputed claims contain “ ‘means-plus-function’ terms governed by 35 U.S.C. § 112, ¶ 6.” Doc. No. 177-1 ¶ 38. Further, the report states that a processor “available for purchase during the relevant [ ] time period is designed to interpret and execute instructions that are provided to it as compiled machine code.” Id. at ¶ 40. According to Defendants’ expert, even a “general purpose processor” without specific instructions can perform “maintenance functions (like stopping, self-testing, or restarting.)”

Federal Circuit precedent requires only that the claim recite some structure. Lighting World, 382 F.3d at 1359-60. Although “processor” may not define a specific structure, it describes a class of structures. See Apple, 757 F.3d at 1300 (citing Personalized Media, 161 F.3d at 705 (finding that “detector” did not evoke particular structure but conveyed to one knowledgeable in the art the variety of structures known as “detectors”); Flo Healthcare Solutions, LLC v. Kappos, 697 F.3d 1367, 1374-75 (Fed.Cir.2012) (finding that “height adjustment mechanism” designates “a class of structures that are generally understood to persons of skill in the art”)). Like “circuit” in Linear, “processor” is a structure-connoting term. See 379 F.3d at 1320. It is not a generic nonstructural term such as “means,” “element,” and “device” that typically do not connote sufficient structure. Apple, 757 F.3d at 1299-1300. As Defendants’ expert noted, a processor can be purchased, can perform certain functions even without specific instructions, and has.a design for interpreting and executing instructions. Thus, the term “processor,” even on its own, recites at least some structure.

Moreover, the Court must not analyze the term “processor” on its own; limitations should be examined as a whole. See Wi-Lan, 2013 WL 4811233, at *42 (citing Apex, 325 F.3d at 1372). When a structure connoting term accompanies a description of its operation, sufficient structural meaning is conveyed to persons of ordinary skill in the art. Linear Tech., 379 F.3d at 1320 (finding language describing the objective of a “circuit” such as “monitoring a signal” suggested sufficient structure to a person of ordinary skill in the art); see also Eolas Techs., Inc. v. Adobe Sys., Inc., 810 F.Supp.2d 795, 810 (E.D.Tex.2011); Aloft Media, LLC v. Adobe Sys. Inc., 570 F.Supp.2d 887, 898 (E.D.Tex.2008), adopted, No. 6:07-CV-355, 2008 WL 5784443 (E.D.Tex. Sept. 24, 2008). Additionally, the limitations must be read in light of the “remaining claim language, specification, prosecution history, and relevant extrinsic evidence.” Apple, 757 F.3d at 1298. “Structure may also be provided by describing the claim limitation’s operation such as its input, output, or connections.” Id. at 1300. Here, the “processor” terms at issue are coupled to “controlling access to data” and “implementing ... code.” These accompanying phrases describe the processor’s objective and operation. The patents further describe the processor’s connections where, in one example, it is “coupled to said nonvolatile memory, said program store, said wireless interface, and a user interface. ...” ’772 Patent col. 27:62-63; see also id. col 31:5-7 (“a processor coupled to the user interface, to the data carrier interface and to the program store for implementing the stored code-”). Contrary to Defendants’ assertions, the patent need not disclose a specific algorithm for performing claimed functions. Apple, 757 F.3d at 1298. Accordingly, Defendants failed to overcome the strong presumption that § 112, ¶ 6 does not apply to the “processor” claim limitations, none of which include the term “means.”

Personal Audio

In Personal Audio, another court in this District found that the strong presumption against means-plus-function treatment flowing from the absence of “means” had been rebutted. Personal Audio, 2011 WL 11757163, at *21-22. As in this case, the claim limitations recited a “processor.” Id. However, the reasoning in Personal Audio relied heavily on Aristocrat. Id.' Since Personal Audio, the Federal Circuit clarified that “where the claim is not drafted in means-plus-function format, the reasoning in the Aristocrat line of cases does not automatically apply, and an algorithm is not necessarily required.” Apple, 757 F.3d at 1298. The Aristocrat reasoning applies where a patentee has expressly invoked means-plus-function claiming to determine whether the patentee has disclosed sufficient structure to define the scope of such a claim. Accordingly, the analysis of recited structure in Personal Audio differs from the Federal Circuit’s guidance in Apple.

Moreover, Personal Audio differs further from .this case. In Personal Audio, both asserted patents shared a common specification and nearly identical claims were at issue. 2011 WL 11757163, at *1-2, *21-22. The second-issued patent was a divisional of the first-issued patent. Id. at *1. The court noted that “[t]he claim terms at issue in the [second-issued] patent are nearly identical to the means-plus-function terms found in the [first-issued] patent, except that ‘means for’ and ‘means responsive’ have been replaced with “processor for” and “said processor responds.” Id. at *21. Accordingly, there was support for finding that the “processer” terms did not describe structure and were simply a substitute for “means for,” which overcame the presumption. See Lighting World, 382 F.3d at 1360. In this case, “processor” has not simply replaced “means” in otherwise identical claim language between asserted patents. Therefore, Personal Audio is even less persuasive in this situation.

Conclusion

The R & R’s reasoning on the “processor” terms follows Federal Circuit precedent on the strong presumption against applying § 112 ¶ 6 where claims do not recite “means.” Defendants cite case law instead addressing the adequacy the specification’s disclosure for defining claim scope where a patentee has explicitly invoked means-plus-function claiming. Even though Personal Audio is from this District, it does not control here for the reasons above. Accordingly, Defendants failed to overcome the presumption against treating the “processor” limitations as means-plus-function claims.

Having also made a de novo review of the other objections filed by Defendants, the Court finds that the findings, conclusions, and recommendation of the Magistrate Judge are correct and Defendants’ objections are without merit. Therefore, the Court hereby ADOPTS the Report and Recommendation of the United States Magistrate Judge as the findings and conclusions of this Court. Accordingly, all objections are overruled.

It is SO ORDERED.

REPORT AND RECOMMENDATION

K. NICOLE MITCHELL, UNITED STATES MAGISTRATE JUDGE

This Memorandum Opinion construes the disputed claim terms in United States Patent' Numbers: (1) 7,334,720; (2) 7,942,-317; (3) 8,033,458; (4) 8,061,598; (5) 8,118,221; and (6) 8,336,772. Also before the Court are Defendants Apple, Inc., Robot Entertainment, Inc., Kinglsle Entertainment, Inc., Samsung Electronics Co., Ltd., Samsung Electronics America, Inc., Samsung Telecommunications America, LLC, HTC Corporation, HTC America, Inc., Exedea, Inc. and Game Circus LLC’s (collectively “Defendants”) Motions for Summary Judgment of Indefiniteness (6:13-cv-447 Doc. No. 161 & 6:13-cv-448 Doc. No. 177) (“Motions for Summary Judgment”). On July 17, 2014, the parties presented arguments on the disputed claim terms and the Motions for Summary Judgment at the Markman hearing. For the reasons discussed below, the Court resolves the claim term disputes as stated below and recommends that Defendants’ Motions for Summary Judgment of Indefiniteness be DENIED.

BACKGROUND

On May 29, 2013, Plaintiffs Smartflash LLC and Smartflash Technologies 'Limited (collectively “Smartflash”) filed two separate actions, one against Defendants Apple, Inc., Robot Entertainment, Inc., Kinglsle Entertainment, Inc., and Game Circus LLC (6:13-cv-447), and one against Defendants Samsung Electronics Co., Ltd., Samsung Electronics America, Inc., Samsung Telecommunications America, LLC, HTC Corporation, HTC America, Inc., Exedea, Inc. and Game Circus LLC (6:13-cv-448). Smartflash alleges Defendants infringe the following patents: U.S. Patent No. 7,334,720; U.S. Patent No. 7,942,317; U.S. Patent No. 8,033,458; U.S. Patent No. 8,061,598; U.S. Patent No. 8,118,221; and U.S. Patent No. 8,336,772. All patents are titled “Data Storage and Access Systems.” The patents-in-suit all stem from a common specification and share a common written description and figures. In the interest of simplicity, the ’720 Patent is cited unless otherwise specified.

APPLICABLE LAW

Claim Construction

“It is a ‘bedrock principle’ of patent law that ‘the claims of a patent define the invention to which the patentee is entitled the right to exclude.” Phillips v. AWH Corp., 415 F.3d 1303, 1312 (Fed.Cir.2005) (quoting Innova/Pure Water, Inc. v. Safari Water Filtration Sys., Inc., 381 F.3d 1111, 1115 (Fed.Cir.2004)). The Court examines a patent’s intrinsic evidence to define the patented invention’s scope. Id. at 1313-1314; Bell Atl. Network Servs., Inc. v. Covad Commc’ns Group, Inc., 262 F.3d 1258, 1267 (Fed.Cir.2001). Intrinsic evidence includes the claims, the rest of the specification and the prosecution history. Phillips, 415 F.3d at 1312-13; Bell Atl. Network Servs., 262 F.3d at 1267. The Court gives claim terms their ordinary and customary meaning as understood by one of ordinary skill in the art at the time of the invention. Phillips, 415 F.3d at 1312-13; Alloc, Inc. v. Int’l Trade Comm’n, 342 F.3d 1361, 1368 (Fed.Cir.2003).

Claim language guides the Court’s construction of claim terms. Phillips, 415 F.3d at 1314. “[T]he context in which a term is used in the asserted claim can be highly instructive.” Id. Other claims, asserted and unasserted, can provide additional instruction because “terms are normally used consistently throughout the patent.” Id. Differences among claims, such as additional limitations in dependent claims, can provide further guidance. Id.

“[C]laims ‘must be read in view of the specification, of which they are a part.’ ” Id. (quoting Markman v. Westview Instruments, Inc., 52 F.3d 967, 979 (Fed.Cir.1995)). “[T]he specification ‘is always highly relevant to the claim construction analysis. Usually, it is dispositive; it is the single, best guide to the meaning of a disputed term.’ ” Id. (quoting Vitronics Corp. v. Conceptronic, Inc., 90 F.3d 1576, 1582 (Fed.Cir.1996)); Teleflex, Inc. v. Ficosa N. Am. Corp., 299 F.3d 1313, 1325 (Fed.Cir.2002). In the specification, a pat-entee may define his own terms, give a claim term a different meaning that it would otherwise possess, or disclaim or disavow some claim scope. Phillips, 415 F.3d at 1316. Although the Court generally presumes terms possess their ordinary meaning, this presumption can be overcome by statements of clear disclaimer. See SciMed Life Sys., Inc. v. Advanced Cardiovascular Sys., Inc., 242 F.3d 1337, 1343-44 (Fed.Cir.2001). This presumption does not arise when the patentee acts as his own lexicographer. See Irdeto Access, Inc. v. EchoStar Satellite Corp., 383 F.3d 1295, 1301 (Fed.Cir.2004).

The specification may also resolve ambiguous claim terms “where the ordinary and accustomed meaning of the words used in the claims lack sufficient clarity to permit the scope of the claim to be ascertained from the words alone.” Teleflex, Inc., 299 F.3d at 1325. For example, “[a] claim interpretation that excludes a preferred embodiment from the scope of the claim ‘is rarely, if ever, correct.” Globetrotter Software, Inc. v. Elan Computer Group Inc., 362 F.3d 1367, 1381 (Fed.Cir.2004) (quoting Vitronics Corp., 90 F.3d at 1583). But, “[although the specification may aid the court in interpreting the meaning of disputed language in the claims, particular embodiments and examples appearing in the specification will not generally be read into the claims.” Constant v. Advanced Micro-Devices, Inc., 848 F.2d 1560, 1571 (Fed.Cir.1988); see also Phillips, 415 F.3d at 1323.

The prosecution history is another tool to supply the proper context for claim constraction because a patentee may define a term during prosecution of the patent. Home Diagnostics Inc. v. LifeScan, Inc., 381 F.3d 1352, 1356 (Fed.Cir.2004) (“As in the case of the specification, a patent applicant may define a term in prosecuting a patent”). The well-established doctrine of prosecution disclaimer “precludes] patentees from recapturing through claim interpretation specific meanings disclaimed during prosecution.” Omega Eng’g Inc. v. Raytek Corp., 334 F.3d 1314, 1323 (Fed.Cir.2003). The prosecution history must show that the paten-tee clearly and unambiguously disclaimed or disavowed the proposed interpretation during prosecution to obtain claim allowance. Middleton Inc. v. 3M Co., 311 F.3d 1384, 1388 (Fed.Cir.2002); see also Springs Window Fashions LP v. Novo Indus. L.P., 323 F.3d 989, 994 (Fed.Cir.2003) (“The disclaimer ... must be effected with ‘reasonable clarity and deliberateness.’ ”) (citations omitted)). “Indeed, by distinguishing the claimed invention over the prior art, an applicant is indicating what the claims do not cover.” Spectrum Int’l v. Sterilite Corp., 164 F.3d 1372, 1378-79 (Fed.Cir.1998) (quotation omitted). “As a basic principle of claim interpretation, prosecution disclaimer promotes the public notice function of the intrinsic evidence and protects the public’s reliance on definitive statements made during prosecution.” Omega Eng’g, Inc., 334 F.3d at 1324.

Although, "less significant than the intrinsic record in determining the legally operative meaning of claim language," the Court may rely on extrinsic evidence to "shed useful light on the relevant art." Phillips, 415 F.3d at 1317 (quotation omitted). Technical dictionaries and treatises may help the Court understand the underlying technology and the manner in which one skilled in the art might use claim terms, but such sources may also provide overly broad definitions or may not be indicative of how terms are used in the patent. Id. at 1318. Similarly, expert testimony may aid the Court in determining the particular meaning of a term in the pertinent field, but “conclusory, unsupported assertions by experts as to the definition of a claim term are not useful.” Id. Generally, extrinsic evidence is “less reliable than the patent and its prosecution history in determining how to read claim terms.” Id.

The patent in suit may contain means-plus-function limitations that require construction. Where a claim limitation is expressed in means-plus-function language and does not recite definite structure in support of its function, the limitation is subject to 35 U.S.C. § 112 ¶ 6. Braun Med., Inc. v. Abbott Labs., 124 F.3d 1419, 1424 (Fed.Cir.1997). In relevant part, § 112 mandates that “such a claim limitation be construed to cover the corresponding structure ... described in the specification and equivalents thereof.” Id. (citing 35 U.S.C. § 112 ¶ 6.). Accordingly, when faced with means-plus-function limitations, courts “must turn to the written description of the patent to find the structure that corresponds to the means recited in the [limitations].” Id.

Construing a means-plus-function limitation involves two inquiries. The first step requires “a determination of the function of the means-plus-function limitation.” Medtronic, Inc. v. Advanced Cardiovascular Sys., Inc., 248 F.3d 1303, 1311 (Fed.Cir.2001). Once a court has determined the limitation’s function, “the next step is to determine the corresponding structure disclosed in the specification and equivalents thereof.” Medtronic, 248 F.3d at 1311. A structure is corresponding “only if the specification or prosecution history clearly links or associates that structure to the function recited in the claim.” Id. Moreover, the focus of the corresponding structure inquiry is not merely whether a structure is capable of performing the recited function, but rather whether the corresponding structure is “clearly linked or associated with the [recited] function.” Id.

Summary Judgment

“Summary judgment is appropriate in a patent case, as in other cases, when there is no genuine issue as to any material fact and the moving party is entitled to judgment as a matter of law.” Nike, Inc. v. Wolverine World Wide, Inc., 43 F.3d 644, 646 (Fed.Cir.1994); Fed. R. Civ. P. 56(c). The moving party bears the initial burden of “informing the district court of the basis for its motion” and identifying the matter that “it believes demonstrate^] the absence of a genuine issue of material fact.” Celotex Corp. v. Catrett, 477 U.S. 317, 323, 106 S.Ct. 2548, 91 L.Ed.2d 265 (1986). If the moving party meets this burden, the nonmoving party must then set forth “specific facts showing that there is a genuine issue for trial.” Fed. R. Civ. P. 56(c), see also T.W. Elec. Serv., Inc. v. Pacific Elec. Contractors Ass’n, 809 F.2d 626, 630 (9th Cir.1987).

A party seeking to invalidate a patent must overcome a presumption that the patent is valid. See 35 U.S.C. § 282; Microsoft Corp. v. i4i Ltd. P’ship, — U.S. -, 131 S.Ct. 2238, 2243, 180 L.Ed.2d 131 (2011); United States Gypsum Co. v. National Gypsum Co., 74 F.3d 1209, 1212 (Fed.Cir.1996). This presumption places the burden on the challenging party to prove the patent’s invalidity by clear and convincing evidence. Microsoft, 131 S.Ct. at 2243; United States Gypsum Co., 74 F.3d at 1212. Close questions of indefiniteness “are properly resolved in favor of the patentee.” Datamize, LLC v. Plumtree Software, Inc., 417 F.3d 1342, 1348 (Fed.Cir.2005); Exxon Research & Eng’g Co. v. United States, 265 F.3d 1371, 1380 (Fed.Cir.2001).

Claims must particularly point out and distinctly claim the invention. “The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention.” 35 U.S.C. § 112 ¶ 2. The primary purpose of the requirement of definiteness is to provide notice to those skilled in the art of what will constitute infringement. See United Carbon Co. v. Binney Co., 317 U.S. 228, 236, 63 S.Ct. 165, 87 L.Ed. 232 (1942). The definiteness standard is one of reasonableness under the circumstances, requiring that, in light of the teachings of the prior art and the invention at issue, the claims apprise those skilled in the art of the scope of the invention with a reasonable degree of precision and particularity. See Shatterproof Glass Corp. v. Libbey-Owens Ford Co., 758 F.2d 613, 624 (Fed.Cir.1985). To rule “on a claim of patent indefiniteness, a court must determine whether one skilled in the art would understand what is claimed when the claim is read in light of the specification.” Bancorp. Servs., L.L.C. v. Hartford Life Ins. Co., 359 F.3d 1367, 1372 (Fed.Cir.2004). “A determination of indefiniteness is a legal conclusion that is drawn from the court’s performance of its duty as the con-struer of patent claims, [and] therefore, like claim construction, is a question of law.” Atmel Corp. v. Info. Storage Devices, Inc., 198 F.3d 1374, 1378 (Fed.Cir.1999).

I. Claim Construction

A. Agreed Terms

The parties have agreed to the construction of one term. Doc. No. 180 at 6.

In view of the parties’ agreements on the proper construction of this term, the Court ADOPTS AND APPROVES this construction.

B. Disputed Terms

1. “payment data”

The parties dispute two key issues: (1) whether “payment data” makes payments or represents payments; and (2) whether “payment data” is distinct from other forms of data.

Smartflash proposes that “payment data” is merely any data that can be used to pay for content. Smartflash argues that the patents-in-suit make it clear that the purpose of “payment data” is to make payments, not to represent a payment that has been made. Opening Brief at 5. Smartflash relies on Figure 12c, which diagrams a process beginning with “payment data for making a payment.” Id. at 5 (citing ’720 21:15 — 21;16). Smartflash argues that Defendants’ construction is inappropriate because it would make certain claims nonsensical. Id. For' example, Claim 30 of the ’772 patent requires a device to transmit payment data for an item in response to, a user selection for the item. ’772 at 31:19-26. According to Smartflash, ' Defendants’ construction would mean this claim requires a user to pay for an item before even selecting it. Opening Brief at 5. Smartflash also contends that “access control data” or “user identity data” may act as payment data if either is used to pay for content. Id. at 6.

Defendants contend that “payment data” can only be one of two things: (1) data representing an actual payment; or (2) data recording such payment. Apple Resp. at 2-3. In support, Defendants point to specification language stating, “payment data received' may either be data relating to an actual payment made to the data supplier or it may be a record of a payment made.... ” Id. at 2 (citing ’720 Patent at 6:58-63). Defendants argue that their proposal is not nonsensical because it is not limited to prior payments. Id. at 3. According to Defendants, their construction only requires that “payment data” reflect actual payment, whether past or present. Id. Thus the claim language would not be nonsensical because payment would only be made after a user selects the content. Id. Additionally Defendants argue that “[t]he specification consistently describes ‘payment data’ as being distinct from access control data and user identity data.” Samsung Resp. at 3-4 (citing ’720 Patent at 4:31-33 & 17:62-18:5). According to Defendants, “access control data” and “user identity data” are independent of “payment data” and thus, may be used to access payment data, which is the only type of data the patents ever describe as being “used to pay for content.” Samsung Resp. at 4-5 (citing ’720 Patent at 5:30-33 & 14:57-61).

The specification discloses using payment data to “make a payment” through an e-payment system or through the “system owner’s data supply computer.” ’720 Patent at 20:8-10 & 21:15-26 (“[P]ayment data for making a payment to the system owner is received ... and forwarded to an e-payment system.... Payment record data, validating payment by the card to the system owner, is then received back from the e-payment system.... ”). This disclosure shows that “payment data” can do more than just represent payments as Defendants contend.

Defendants’ proposal also seeks to import a negative limitation into the construction of “payment data” that would exclude “user identity data” and “access control data.” As Defendants note, the Summary of the Invention discusses “payment data” and “identification data” in relation to one another. ’720 Patent at 4:31-33 (“The payment data will normally be linked to a card or card holder identification data for payment by the card holder.”). Statements that describe the invention as a whole, rather than preferred embodiments, are more likely to support a limiting definition of a claim term. C.R. Bard, Inc. v. U.S. Surgical Corp., 388 F.3d 858, 864 (Fed.Cir.2004). This type of statement is more likely to be found in certain sections of the specification, such as the Summary of the Invention. Id.

Turning to the claims of the patent, Claim 30 of the ’772 patent is representative and states:

30. A data access terminal for controlling access to one or more content data items stored on a data carrier, the data access terminal comprising:

a user interface;

a data carrier interface;

a program store storing code implementable by a processor; and

a processor coupled to the user interface, to the data carrier interface and to the program store for implementing the stored code, the code comprising:

code responsive to said first user selection' of said selected at least one content data item to transmit payment data relating to payment for said selected at least one content item for validation by a payment validation system;

code to receive payment validation data defining if said payment' validation system has validated payment for said selected at least one content data item;

’772 Patent at 30:65-31:7 & 31:22-29 (emphasis added). Claim 30 does not refer to user identification data, nor does it preclude “payment data” from being user identification data.

In support of their argument, Defendants cite to Claim 12 of the ’598 Patent, which does recite both “payment data” and “identification data”:

12. a portable data carrier as claimed in claim 10, wherein the code to provide payment to the payment validation system comprises code to provide the payment data and/or identification data to the network operator.

The recitation of both “payment data” and “identification data” in the same claim suggests that these terms do refer to different, distinct data. See Becton, Dickinson & Co. v. Tyco Healthcare Group, LP, 616 F.3d 1249, 1254 (Fed.Cir.2010) (“Where a claim lists elements separately, the clear implication of the claim language is that those elements are distinct components of the patented invention.”) (citations and internal quotation marks omitted). However, Claim 12 of the ’598 Patent also suggests that identification data itself may be used for payment. This reading is consistent with the claims from which Claim 12 depends, such as Claim 8. Claim 8 recites:

8. A portable data carrier as claimed in Claim 7, wherein code to provide payment to the payment validation system comprises code to provide the identification data identifying the user of the portable data carrier to the payment validation system.”

’598 Patent at 26:29-33.

Given this claim language, Defendants’ proposed negative limitation is not warranted. Similarly, Defendants’ proposal that “payment data” can only represent “actual payment made or record of payment made” is too narrow. The specification and cited claim language uses payment data broadly to refer to whatever data is being used “for making a payment.” ’720 Patent at 21:15; ’598 Patent at Cl. 8. Accordingly, “payment data” is construed to mean “data that can be used to make a payment for content.”

2. “payment validation system”

The parties agree that the “payment validation system” is a system that validates payment data. The parties dispute whether “payment validation system” should have the additional limitation that it authorizes payment.

Smartflash argues that the claim language is clear and that no construction is necessary. Opening Brief at 7. Smart-flash contends that Defendants’ proposal would exclude certain embodiments. Id. at 7-8. According to Smartflash, Defendants’ construction relies on certain embodiments in the specification where a user device transfers payment data to a data supplier that relies on a third party payment authority to process and authorize the payment. Id. at 8 (citing ’720 Patent at 11:66-12:4). Smartflash argues • that other portions of the specification directly contradict this construction because “payment validation system” is also used to refer to a system that validates payment data without performing the additional functions of a banking process system. Id. (citing ’720 Patent at 13:53-13:62).

Defendants contend that the specification teaches that the “payment validation data” both validates and authorizes payment. Apple Resp. at 5 (citing ’720 Patent at 8:21-23). Defendants argue that this is the only portion of the specification that describes the role of the “payment validation system.” Id. According to Defendants, their construction only requires that the payment validation system be capable of validating payment data and authorizing payment in response to receipt of payment data, thus infringement is not tied to a particular use as Smartflash contends. Id. at 6-7 (citing Nazomi Commc’ns, Inc. v. Nokia Corp., 739 F.3d 1339, 1344 (Fed.Cir.2014)). Defendants argue that this is consistent with the inventors’ stated goal of reducing data piracy by “binding the data access and payment together.” Samsung Resp. at 5 (citing ’720 Patent at 1:66-2:3).

The Summary of the Invention states:

The combination of the payment validation means with the data storage means allows the access to the downloaded data[,] which is to be stored by the data storage means, to be made conditional upon checked and validated payment being made for the data. Binding the data access and payment together allows the legitimate owners of the data to make the data available themselves over the internet without fear of loss of revenue, thus undermining the position of data pirates.

The terminal reads payment data from the data carrier and transmits this to a payment validation system for validating the data and authorizing payment. This may be part of the data supplier’s computer system or it may be a separate system such as an e-payment system.

The payment validation system may be part of the data supplier’s computer systems or it may be a separate e-payment system. In one embodiment the method further comprises receiving payment validation data from the payment validation system; and transmitting at least a portion of the payment validation data to the data supplier.

’720 Patent at 1:62-2:3, 8:21-25 & 8:64-9:2 (emphasis added).

Smartflash is correct that “[t]he fact that a patent asserts that an invention achieves several objectives does not require that each of the claims be construed as limited to structures that are capable of achieving all of the objectives.” See Liebel-Flarsheim Co. v. Medrad, Inc., 358 F.3d 898, 908 (Fed.Cir.2004). Indeed, the specification also discloses e-payment systems where payment authentication is performed at a later stage. See ’720 Patent at 23:22-33 (“[p]ayment may be made directly to the system owner, and either concurrently with the content access and download process, or at some later stage ....”) (emphasis added). In such a system, the content supplier could “validate” the payment by allowing a purchase on credit, with actual payment to occur at a later time. Thus, the specification is not as clear as Defendants have argued. Indeed the specification disclosure of “validating the data and authorizing the payment” suggests that “authorizing” is distinct from “validating.” See ’720 Patent at 8:21-25.

However, Smartflash’s proposed construction is not complete. The payment validation system is not limited to returning data in response to only valid payment data. The system must return whatever data results from an attempt to validate payment data. See ’772 Patent at Claim 30 (“code to receive payment validation data defining if said payment validation system has validated payment for said selected at least one content data item”). The purpose of a validation system would be moot if it only worked when valid payment data was sent. Accordingly, “payment validation system” is construed to mean “system that returns payment validation data based on an attempt to validate payment data.”

3. “payment validation data”

The dispute for this term is similar to the previous dispute for “payment validation system.” Smartflash argues that “payment validation data” is data returned from a payment validation system indicating that payment data is valid. Opening Brief at 11. Smartflash contends that “payment validation data” is not required to authorize payment as Defendants’ construction would require. Id. According to Smartflash, Defendants’ construction is inconsistent with the plain language of the term, which refers to validation data, not authorization data. Id. at 12.

Defendants’ construction requires that the “payment validation data” represent that payment data was both validated and authorized. Defendants rely on the same arguments discussed previously for “payment validation system.” See Apple Resp. at 5-7; Samsung Resp. at 5-8. Thus, if the “payment validation system” must authorize the payment data, then the “payment validation data” must represent that authorization.

As previously discussed, the parties’ constructions for this term are too narrow. See ’772 Patent Claim 80 (“code to receive payment validation data defining if said payment validation system has validated payment for said selected at least one content data item.”). Thus, “payment validation data” is merely data received from a payment validation system and relates to whether a payment has been validated. Such a construction would add little clarity to the plain language of the term. Accordingly, “payment validation system” is construed to have its plain meaning.

4. “content data memory” / “non-volatile data memoiy” / “memory ... for storing data” / “memory configured to store ... content” / “parameter memory” / “use rule memory”

These terms all deal with types of memory for storing content. Smartflash contends that these “memory” terms do not need to be construed because the plain and ordinary meaning is sufficient. Opening Brief at 12. According to Smartflash, “the mere fact that some claims use two different phrases to identify required memory does not imply that those claims require ‘physically’ separate memories” because a single component may satisfy multiple elements of a claim. Id. at 13 (citing Cannon Rubber Ltd. v. First Years, Inc., 163 Fed.Appx. 870, 877 (Fed.Cir.2005) & Intellectual Property Development, Inc. v. UA-Columbia Cablevision, 336 F.3d 1308, 1320 n.9 (Fed.Cir.2003)). Smartflash argues that many of the asserted claims recite memory used to store different things, but that none of the claims require the memories be “physically separate.” Id. at 12-13. Smartflash contends that Defendants’ argument is flawed because the claims in the ’772 Patent require “non-volatile memory configured to store multimedia content,” but do not require any “parameter memory” or “use rule memory.” Id. at 13. Thus, according to Smartflash, Defendants’ construction would require that “parameter memory” and “use rule memory” be physically separate from the claimed memory, even though “parameter memory” and “use rule memory” are not actually required by the claims. Id.

Defendants respond that the use of the conjunction “and” in a claim indicates that an inventor intended to claim distinct, separate components. Apple Resp. at 16 (citing TIP Sys., LLC v. Phillips & Brooks/Gladwin, Inc., 529 F.3d 1364, 1375-76 (Fed.Cir.2008) & Gaus v. Conair Corp., 363 F.3d 1284, 1288 (Fed.Cir.2004)). Defendants also rely on the prosecution history for the ’720 Patent. Defendants point to a response to a 2007 office action, where the applicants amended their claims to include “parameter memory” separate from the “content memory” as well as a requirement that “use rules” and “use status data” be read “from the parameter memory.” Apple Resp. at 18. Defendants argue that these amendments require separate memory, stored on separate chips, because the prior art Hiroya “disclosed that the ticket information and the electronic signature would be stored separately on the same chip.” Id. at 19. According to Defendants, this separate storage is needed to achieve the goals of the invention, otherwise “use status data” could not be updated as described in the patentsl Samsung Resp. at 11 (citing ’720 Patent at 4:53-5:24).

Distinctly recited limitations are usually interpreted as distinct structures. See Becton, 616 F.3d at 1254 (“Where a claim lists elements separately, the clear implication of the claim language is that those elements are distinct components of the patented invention.”) (citations and internal quotation marks omitted). The specification discloses distinct memory structures. See ’720 Patent at 17:40-42, 18:8-10, & 18:18-20. Likewise, Figure 9 in the specification illustrates the “content data memory 214” and “non-volatile data memory 218” separately.

Defendants rely on the prosecution history to argue that these distinct memories must also be “physically separate.” The patentee’s statements regarding the Hiro-ya prior art reference are as follows:

22. (Currently Amended) A method of controlling access to content data on a data carrier, the data carrier comprising non-volatile data memory storing content memory and non-volatile parameter memory storing use status data and use rules, the method comprising:

receiving a data access request from a user for at least one content item of the content data stored in the non-volatile data memory;

reading the use status data and use rules from the parameter memory that pertain to use of the at least one requested content item; and evaluating the use status data using the use rules to determine whether access to the stored data at least one requested content item stored in the content memory is permitted; and [[.]] displaying to the user whether access is permitted for each of the at least one requested content item stored in the non-volatile data memory.

Claims 22, 23, 35-50, and 59-62 are rejected under 35 U.S.C. § 102(b) as being anticipated by Hiroya (U.S. Patent No. 5,754,654). Applicants respectfully submit that Hiroya does not disclose each element of these claims.

For example, Applicants’ claim 22 as amended recites a method of controlling access to content data on a data carrier, the data carrier comprising non-volatile data memory storing content memory and non-volatile parameter memory storing use status data and use rules, the method comprising:

receiving a data access request from a user for at least one content item of the content data stored in the nonvolatile data memory;

reading the use status data and use rules from the parameter memory that pertain to use of the at least one requested content item;

evaluating the use status data using the use rules to determine whether access to the at least one requested content item stored in the content memory is permitted; and

displaying to the user whether access is permitted for each of the at least one requested content item stored in the non-volatile data memory

... Such limitations are not disclosed by Hiroya.

Hiroya discloses an electronic ticket vending and refunding system wherein a ticket purchaser can purchase a ticket to an event, etc., through a man-machine interface, whereby the ticket information is transferred to an electronic ticket storage device (col. 11, lines 36-49). In this system, the electronic ticket is stored in the electronic ticket storage device and includes ticked [sic, ticket] information data and an electronic signature (col. 15, lines 62-67), and the ticket can he redeemed by decrypting the electronic signature and ticket information data so that a man-machine interface can verify the validity of the electronic ticket (col. 23, line 64-col. 24, line 18). Hiroya does not disclose status data and use rules stored in a parameter memory, wherein the use rules stored on the non-volatile memory are used to analyze the use status data stored on the non-volatile memory to determine whether access to separately-stored requested content is permitted as required in Applicants’ claim 22 as amended. Hi-roya discloses that electronic ticket information itself includes both the ticket data and the validity data, and that the electronic ticket information must be decrypted to be validated. Hiroya does not disclose use status data stored separately from associated content data, and since ticket data is either valid or not valid in and of itself and does not in-, elude separate use data, Hiroya does not suggest or provide motivation to store use data as recited in claim 22. Further, as Hiroya discloses only .ticket information that can be redeemed, and not content that can be accessed multiple times, partially used, used at different times, etc., such that there would be no motivation to include use data with the device of Hiroya. As Hiroya does not disclose such limitations, Hiroya cannot anticipate Applicants’ claim 22 or the claims that depend therefrom.

Doc. No. 160, Ex. G, 2/6/2007 Amendment at 2 & 9-10 (emphasis and formatting modified). Defendants interpret these statements as applicant arguing that content data being stored in a separate chip is what distinguishes it from the prior art.

Reading the statements in their entirety, the applicant was not arguing that the content data must be physically separate from other data. Instead, the applicant relied on evaluating “separate use data” according to use rules. The applicant contrasted the invention with the electronic ticket information of Hiroya, which was validated by an electronic signature, not use rules. The applicants’ remarks do not rise to the level of “definitive statements” or a “clear and unmistakable” disclaimer that warrants importing Defendants’ limitation. See Omega Eng’g, Inc. v. Raytek Corp., 334 F.3d 1314, 1324 (Fed.Cir.2003) (“As a basic principle of claim interpretation, prosecution disclaimer promotes the public notice function of the intrinsic evidence and protects the public’s reliance on definitive statements made during prosecution.”) (emphasis added); see also San-Disk Corp. v. Memorex Prods., Inc., 415 F.3d 1278, 1286-87 (Fed.Cir.2005) (“There is no ‘clear and unmistakable’ disclaimer if a prosecution argument is subject to more than one reasonable interpretation, one of which is consistent with a proffered meaning of the disputed term.”) (citations and internal quotation marks omitted).

Additionally, Defendants rely on corporate documents created by Smartflash’s predecessor that refer to a “Smartflash card” with a “second flash memory chip which can store downloaded music.” Apple Resp. at 13 (quoting Ex, K at SF00031496; citing Ex. H at SF00015316). However, relying on extrinsic evidence to import a limitation is disfavored. See Phillips v. AWH Corp., 415 F.3d 1303, 1317 (Fed.Cir.2005) (“[W]hile extrinsic evidence can shed useful light on the relevant art, we have explained that it is less significant than the intrinsic record in determining the legally operative meaning of claim language.”) (citations and internal quotation marks omitted); id. at 1319 (“[E]x-trinsic evidence may be useful to the court, but it is unlikely to result in a reliable interpretation of patent claim scope unless considered in the context of the intrinsic evidence.”). Defendants’ proposed limitation is rejected. Accordingly, “content data memory,” “non-volatile data memory,” “memory ... for storing data,” “memory configured to store ... content,” “parameter memory,” and “use rule memory” are construed to have their plain meaning. The patent does not' require that these be physically separate.

5. “data carrier”

The dispute over “data carrier” is whether the data carrier can be a general data storage medium, as Smartflash proposes, or whether it must be a smart card or integrated circuit card.

Smartflash believes no construction is necessary for “data carrier.” Smartflash argues that Defendants’ proposals improperly import new limitations into the claims. Opening Brief at 17 (citing Phillips, 415 F.3d at 1324-27, 1329-30). According to Smartflash, some, but not all, embodiments of a data carrier are removable smart cards or IC cards. Id. at 18. In support, Smartflash cites to portions of the specification it contends disclose data carriers integrated with other apparatuses. Id. (citing ’720 Patent at 16:6-10). Additionally, Smartflash argues that the “data carrier” does not require separate nonvolatile memories for the same reasons as the previous “memory” terms. Opening Brief at 20. Finally, Smartflash contends that the construction should not define what must be stored on all data carriers because each claim specifies what must be on the carrier. Id. at 21.

Defendants respond that the patents’ descriptions and embodiments uniformly describe the “data carrier” as a removable smart card or IC card. Apple Resp. at 7. Defendants also note that Smartflash has proposed that another disputed term— “the card” — be construed to mean “the data carrier.” Id. at 8. In support of their proposal to require separate memories, Defendants argue that “applicants expressly disclaimed a data carrier with only one memory” by “distinguish[ing] the Hi-roya reference because it lacked separate memories for respectively[ ] storing (1) use status data and (2) content storage memory.” Id. at 11.

The first issue is whether to require a “removable smart card.” The Summary of the Invention states:

The data memory for storing content data may be optic, magnetic or semiconductor memory, but preferably comprises Flash Memory.... Preferably the card is configured as an IC card or smart card and has a credit card-type format, although other formats such as the “memory stick” format may also be used. This provides a small and convenient portable format and facilitates removable interfacing with a variety of devices.

’720 Patent at 6:17-31 (emphasis added); see id. at 4:62-64 (“use rules may be linked to payments made from the- card ....”) (emphasis added). Defendants are correct that consistent usage of a claim term in a particular manner could warrant a narrower construction than would otherwise be appropriate based on. the claim language. AstraZeneca LP v. Apotex, Inc., 633 F.3d 1042, 1052 (Fed.Cir.2010) (“[W]hen a pat-entee uses a claim term throughout the entire patent specification, in a manner consistent with only a single meaning, he has defined that term by implication.”).

The specification does disclose a “portable data carrier (30)” that is illustrated as a card in Figure 2 and states that it is “based on a standard smart card....” ’720 Patent at 11:36-40. The same paragraph refers to the “card (30)” using the same numeral (30) that the specification used to refer to the data supplier. Id. at 11:40. Thus, “data carrier” and “card” are used interchangeably to some degree. However, the specification refers to “a data carrier or smart Flash card.” See ’720 Patent at 18:55-58 (“FIGS. 11a and lib show a flow diagram of a process for registering a data carrier or smart Flash card with a data supplier or system owner operating a data supply system as illustrated in FIG. 6.”) (emphasis added). The usage of “or” could either imply that “data carrier” and “smart Flash card” are synonyms, or that a “data carrier” can be something broader than a smart card.

Additionally, the .specification also shows that “data carrier” need not be removable. ’720 Patent at 16:1-10 (“In most embodiments of the terminal the SFC interface allows the smart Flash card data carrier to be inserted into and removed from the terminal, but in some embodiments the data carrier may be integral with the terminal.”) (emphasis added); see id. at 4:42-43 (“the data carrier may also be integrated into other apparatus, such as a mobile communications device.”) (emphasis added). An integrated data carrier would be contrary to the idea of a removable card.

Considering the specification in its entirety, Defendants’ proposed construction would improperly limit “data carrier” to a preferred embodiment. See Constant v. Advanced Micro-Devices, Inc., 848 F.2d 1560, 1571 (Fed.Cir.1998) (“Although the specification may aid the court in interpreting the meaning of disputed language in the claims, particular embodiments and examples appearing in the specification will not generally be read into the claims.”). None of the extrinsic evidence offered by Defendants warrants limiting the generic term “data carrier” to the specific physical structure of a removable card. Additionally, Defendants’ proposal requiring “separate” memories is rejected for the same reasons discussed in the previous term.

Although Smartflash contends that no construction is necessary, “data carrier” will be construed so as to clarify that the “carrier” portion of the term does not refer to a signal carrier wave, such as for wireless communications. Accordingly, “data carrier” is construed to mean “medium capable of storing information.”

6. “portable data carrier”

The dispute over this term is similar to the dispute over the “data carrier” term. The key difference is the dispute over the term portable. Smartflash contends that the word “portable” is commonly understood and thus does not need to be construed. Opening Brief at 22.

The Apple Defendants respond that the specification equates portability with the ability to interface -with a variety of devices.” Apple Resp. at 14-15 (citing ’720 Patent at 6:26-31). The Samsung Defendants contend that “data carrier” and “portable data carrier” are used synonymously throughout the patents. Samsung Resp. at 20 (citing ’720 Patent at 8:10-15, 9:61-63, 10:66, 11:36, 16:4, & 16:7-8). Alternatively, the Samsung Defendants agree with the Apple Defendants that the only difference between a “data carrier” and a “portable data carrier” is that a “data carrier” is a removable card that interfaces with a single or dedicated device, whereas a “portable data carrier” can interface with a variety of devices. Samsung Resp. at 21.

The Summary of the Invention refers to portability as allowing the data carrier to “access content or, in the example, play music without the need to be linked to a communications system or to be on-line to the internet.” ’720 Patent at 5:12-15. Additionally, it states that the “ ‘memory stick’ format may be used .... [to] provide[ ] a small and convenient portable format [that] facilitates removable interfacing with a variety of devices.” Id. at 6:17-31 (emphasis added). These disclosures don’t warrant giving “portable” a special meaning beyond its ordinary meaning of being readily moveable. See Constant, 848 F.2d at 1571; see also Phillips, 415 F.3d at 1323. Based on the previous construction of the term “data carrier,” “portable data carrier” is construed to have its plain meaning.

7. “use rule(s)” / “use rule(s) data” / “data use rule data”

Smartflash contends that there is no ■basis in the patents or prosecution history for the proposition that “use rules” or “access rules” must be “physically separate” from content. Opening Brief at 24. Smartflash argues that there was no clear disavowal in the in the prosecution history, and that any disavowal would not apply to different claim terms appearing in later continuation applications. Id. at 25. Smartflash contends that Defendants’ proposed “indicating permissible use ...” and “specifying under what conditions ...” limitations are taken directly from certain claims and placed into the claim term definitions. Id. at 26. According to Smart-flash, this would force language into other claims where it would not make sense. Id.

For “access rule(s),” Defendants respond that the applicant argued that access rules and content data were written in physically separate memories in order to overcome Hiroya. Apple Resp. at 21. Defendants contend that their construction “aligns with the teachings of the patent to explain that these ‘access rules’ are used to control access to specific content data items....” Id. (citing ’720 Patent at 7:31-33 & 23:59-24:8.).

Defendants argue that their proposed construction for the “use rul
