OPINION OF THE COURT GREENBERG, Circuit Judge. In this case, the American Telephone and Telegraph Company (“AT & T”) seeks to hold the defendants-appellees — Winback and Conserve Program, Inc. (“Winback”) and Alphonse G. Inga — liable for acts of unfair competition by the defendants’ sales representatives. The district court, in an Opinion and Order dated May 12, 1994, denied AT & T’s application for a preliminary injunction, finding that Winback and Inga exerted insufficient control over the sales representatives to justify the imposition of liability upon Win-back and Inga. AT & T v. Winback & Conserve Program, 851 F.Supp. 617 (D.N.J.1994) (“Winback”). Because we find that the district court committed errors of law in denying AT & T’s motion for a preliminary injunction against Winback and Inga, we will vacate the Order of the district court and we will remand the matter for further proceedings. I. Introduction and Factual Background AT & T is a long-distance telecommunications carrier that, as part of its marketing strategy, uses a variety of service marks and trademarks, including the initials “AT & T” and the AT & T “globe” symbol. AT & T markets and sells telecommunications services to customers, and its rates and practices are governed by tariffs it files with the Federal Communications Commission. Not only does AT & T provide services to “end-users” — customers who purchase service for themselves — but, pursuant to a 1976 FCC ruling, AT & T offers long distance telecommunications services it provides under a tariff for resale. See In the Matter of Regulatory Policies Concerning Resale and, Shared Use of Common Carrier Services and Facilities, 60 F.C.C.2d 261 (1976); In the Matter of Regulatory Policies Concerning Resale and Shared Use of Common Carrier Domestic Public Switched Network Services, 83 F.C.C.2d 167 (1980); Winback, 851 F.Supp. at 618. The resale market works as follows: Resellers, or aggregators, subscribe to AT & T programs which provide large discounts for high volume purchases of AT & T telecommunications services. The resellers then sell the services to individual businesses that do not generate sufficient volume to qualify individually for the high-volume discounts. Thus, by providing the services to these end-users, resellers make a profit while end-users receive access to the AT & T network at a significantly lower cost than if they purchased services from AT & T directly. Under some programs — including the one at issue on this appeal — AT & T bills the end-users directly and they make payments directly to AT & T. Also, pursuant to some resale agreements, the end-users receive the services associated with access to the AT & T network directly from AT & T. Nonetheless, in the resale business, only the reseller is a customer of AT & T; the end-users are customers of the reseller and not of AT & T. Appellee Winback is a reseller of 800 inbound telecommunications services and ap-pellee Inga is its president. As a matter of convenience, hereafter we usually will refer to both simply as Winback. Winback offers end-users access to the AT & T 800 inbound network at a discount price. As are other resellers, Winback is both a customer and a competitor of AT & T. This case really began in April 1992, when AT & T filed a complaint and application for a temporary restraining order alleging that one of Inga’s other companies, One Stop Financial, Inc., was infringing on AT & T’s trademarks and service marks, falsely representing that it was affiliated with AT & T and passing itself off as AT & T. The parties resolved the case by entering into a Consent Final Order and Injunction, filed on May 7,1992, which enjoined One Stop and its officers, directors, employees and agents from engaging in such practices. In September 1993, AT & T filed a motion to hold One Stop in civil contempt of the Consent Order. One Stop and Inga defended by arguing that their sales and marketing representatives, over whom One Stop had no control, were responsible for any infringing acts. Consequently, as a result of AT & T’s application, on September 27,1993, the Final Order and Injunction was amended to obligate One Stop to serve each of its sales agents with a copy of the Order, and, in turn, to obligate each of the primary agents to serve the Order upon all subagents they had authorized to market under the name One Stop Financial, Inc. ' Soon after the amended Final Order was filed, AT & T filed a second application to hold One Stop and Inga in contempt, this time basing its claim for relief on allegedly infringing activity on the part of Winback, Inga’s other company (and the corporate defendant in the instant action). Winback, 851 F.Supp. at 620. The district court informed the parties that the motion for contempt would not be heard until discovery was completed. AT & T responded by filing this action, on December 13, 1993, against Win-back and Inga, alleging false designation of origin, passing off, and unprivileged imitation in violation of section 43(a) of the Lanham Act, 15 U.S.C. § 1125(a), as well as various state common law claims. AT & T sought, among other relief, temporary restraints, and preliminary and permanent injunctions. The district court held a hearing on AT & T’s application for a temporary restraining order on December 15, 1993. See Order To Show Cause With Temporary Restraints, app. at 366. On December 17, 1993, the district court issued a temporary restraining order enjoining and restraining “Defendants, together with their officers, agents, servants, employees, attorneys and all persons in active concert or participation with them” from: (a) employing any oral communication, advertisement, label, sign, flyer, envelope or correspondence or any other written documentation that falsely designates the origin of Defendants’ goods or services as being those of the American Telephone and Telegraph Company or of AT & T, or that is likely to cause confusion as to whether Defendants’ goods or services are sponsored by, or affiliated with the American Telephone and Telegraph Company; (b) engaging, producing, creating, encouraging, aiding or abetting any oral communication, advertisement, label, sign, flyer, envelope, correspondence or any other oral or written communication which enables Defendants to pass off their goods or services as being those of the American Telephone and Telegraph Company. Order to Show Cause at 3-4, app. at 367-68. The Order prevented the defendants and their agents from “introducing into ... commerce ... any document promoting or identifying Winback and Conserve Program, Inc., which does not conspicuously identify Win-back and Conserve Program, Inc. as a corporation through the use of the abbreviation, ‘Inc.’ and which does not identify a business mailing address.” Id. Finally, Winback was ordered to serve a copy of the Order upon its primary agents (identified in an Appendix to the Order) who in turn were obligated to serve the Order on any sub-agents they had employed to do Winback’s marketing. The court in that Order set a return date for a hearing on AT & T’s application for a preliminary injunction. Winback answered AT & T’s complaint on January 18, 1994. After expedited discovery, full briefing, and the submission of detailed affidavits, the district court held a hearing on AT & T’s application, between March 1 and March 11, 1994. At the hearing, much of the testimony described Winback’s method of attracting customers. The evidence demonstrated that Winback employs no marketing or sales people on its staff. Rather, it attracts business solely through the use of sales networks and/or marketing representatives. Specifically, it uses about 50 different marketing agencies, which in turn employ or contract with scores more individual sales representatives. The representatives work out of their own offices, and receive no supplies, equipment or space from Winback. Winback compensates these representatives purely on a commission basis, and the representatives are under no minimum obligation to Win-back. Indeed, many representatives market for various resellers. This does not mean, however, that there is little connection between the agents and Winback. The agents are supplied with forms which AT & T requires to be completed to transfer customers to Winback’s services (the transfer forms). Until October 13,1993, these forms contained the initials “AT & T” and the AT & T globe symbol. On that date, AT & T ordered the resellers to delete those references. These forms also make reference to Winback. Moreover, at least one of the representatives contacts Inga on a regular basis, and Inga attempts to “polic[e]” the agents to avoid misrepresentations. Winback, 851 F.Supp. at 619. Generally, as the evidence before the district court demonstrated, sales representatives contact end-users and present them with the Winback plan. The representatives then send prospective customers various forms, including a facsimile .cover sheet, informational documents, the transfer form, and a Main Billed Telephone Numbers Location List (“main billed form”). Interested end-users complete the transfer form and the main billed form and send them back to the representative, who then forwards them to the primary marketing or sales agency. The agency, in turn, sends the forms to Winback, which returns them to AT & T. . Each month, AT & T sends Winback a check for the difference between the discount given Winback by AT & T and the average discount Winback passes on to the end-user. Winback then sends commission checks to the various marketing representatives. At the hearing, AT & T presented evidence that end-user customers were deceived into believing they were dealing with AT & T. First, many witnesses testified that they received telephone solicitations by Winback representatives informing them that they were affiliated with AT & T. See, e.g., Winback, 851 F.Supp. at 621 (citing testimony of Arthur Sanchez and Daniel Flood); certification of Daniel A. Flood at 2, app. 72. Several witnesses also testified that information contained in various written materials misled them into believing that Winback was a division of AT & T. As an example, one employee of an end-user, Debra Vogel, a telecommunications employee of The Toro Company, testified that she was confused by a facsimile transmission entitled “Winback & Conserve Program for AT & T 800 Customers” that she received from a Winback representative. Because ‘Winback & Conserve Program” was not stated as a separate entity (such as by including the letters “Inc.” after “Program”), Vogel believed that Winback & Conserve Program was a marketing arm of AT & T and that the documents she received were official AT & T documents. Winback, 851 F.Supp. at 620-21; certification, app. at 36-40. More generally, several other end-user customers testified to. being confused by the following materials they received .from Win-back’s sales representatives: (1) a facsimile cover sheet not mentioning Winback but stating that “[w]e are bringing you together for less with AT & T network services”, see Winback, 851 F.Supp. at 621; certification of Arthur W. Sanchez at 4 & Exhibit A, app. at 58, 61; (2) a facsimile cover sheet entitled “The New AT & T 800 Winback & Conserve Program” and stating “Please authorize discount acceptance immediately and fax back to 1-800-251-5491 for forwarding to the AT & T Input Department”, see Winback, 851 F.Supp. at 621-22 (citing testimony of Eka-terina Hall, Karen Kelly, Daniel Flood, and Phillip Kenney); (3) the transfer form displaying the AT & T initials and globe symbol in the corner, id. (citing testimony of Ekater-ina Hall, Karen Kelly, Arthur Sanchez, Daniel Flood, Thomas Malanga, and Phillip Ken-ney); (4) a main billed form stating “Win-back & Conserve Program” at the top, id. at 621-23 (citing testimony of Debra Dahl Vo-gel, Ekaterina Hall, Karen Kelly, Phillip Kenney, James Angelici and Kay Mills); (5) an information form detailing the Winback program and instructing the customer to complete the accompanying main billed form “provided to us by AT & T”, id. at 621 (citing testimony of Arthur Sanchez); (6) a form entitled “AT & T 800 Readyline Summary of Charges”, displaying the AT & T initials and globe, id. at 621 (citing testimony of Daniel Flood); and (7) several other documents referencing the ‘Winback and Conserve Program”. Id. at 621-23. Based on the oral representations and the written documents, the witnesses testified that they believed they were dealing with AT & T’s Winback and Conserve Program, rather than with a reseller that was a separate corporation. Id. However, the evidence indicated that all the allegedly infringing actions were performed by the sales agencies or the sales representatives, without the knowledge, consent, assistance or encouragement of Winback or Inga. Id. at 623. Based on this evidence, the district court found that “[tjhere is no question that [AT & T] submitted sufficient proofs to the Court to establish that consumers have been confused by certain oral misrepresentations made by and written documents provided by the Win-back sales representatives.” Id. at 630. The court then addressed whether Winback and Inga could be held responsible for the acts of their sales representatives. The court looked to the common law of torts “to determine the boundaries of liability.” Id. at 624. It then asked whether, pursuant to New Jersey law of agency, Winback and/or Inga could be held vicariously liable for the torts of their sales agents. Relying primarily on a recent New Jersey Supreme Court case distinguishing between agents (for whose torts the principal may be hable) and independent contractors (for whose torts the principal generally may not be held hable), the court found that AT & T only had estabhshed that the sales representatives were independent contractors. AT & T, in the court’s view, had not met its burden of proving that Win-back and/or Inga exercised sufficient control over their sales representatives to constitute an agency relationship. The court primarily rehed on the facts that the representatives are commissioned rather than salaried, that they work on behalf of a number of companies, and that their operating expenses and business are purely their own responsibilities. Thus, the court concluded, “the level of joint activity between [Winback] and Inga and the sales representatives is ... minimal and peripheral to the nuts and bolts of the business of marketing and promoting.” Id. at 626. Furthermore, the court found that AT & T contributed to the customers’ confusion, that the resale business was inherently confusing as to the point of origin of the service, and that the public interest did not weigh in favor of granting an injunction. Thus, the district court denied AT & T’s application for a preliminary injunction, and vacated the temporary restraints. AT & T timely filed a notice of appeal from the district court’s order. We have jurisdiction pursuant to 28 U.S.C. § 1292(a)(1). The district court properly exercised jurisdiction over AT & T’s Lanham Act claims pursuant to 28 U.S.C. §§ 1331, 1338, and 1367. II. Discussion A. Standard of Review “[T]he grant of injunctive relief is an extraordinary remedy ... which should be granted only in limited circumstances.” Frank’s GMC Truck Center, Inc. v. General Motors Corp., 847 F.2d 100, 102 (3d Cir.1988) (citing United States v. City of Philadelphia, 644 F.2d 187, 191 n. 1 (3d Cir.1980)). This proposition is particularly apt in motions for preliminary injunctions, when the motion comes before the facts are developed to a full extent through the normal course of discovery. In ruling on a motion for a preliminary injunction, the court must consider: (1) the likelihood that the plaintiff will prevail on the merits at final hearing; (2) the extent to which the plaintiff is being irreparably harmed by the conduct complained of; (3) the extent to which the defendant will suffer irreparable harm if the preliminary injunction is issued; and (4) the public interest. Opticians Ass’n v. Independent Opticians, 920 F.2d 187, 191-92 (3d Cir.1990). The injunction should issue only if the plaintiff produces evidence sufficient to. convince the district court that all four factors favor preliminary relief. Id. at 192. Merchant & Evans, Inc. v. Roosevelt Bldg. Prods., 963 F.2d 628, 632-33 (3d Cir.1992). Our review of the district court’s decision is limited. We must affirm unless, in denying the motion, “ ‘there has been an abuse of discretion, an error of law, or a clear mistake in the consideration of the proof.’ ” Frank’s GMC Truck Center, 847 F.2d at 101 (quoting Moteles v. University of Pennsylvania, 730 F.2d 913, 918 (3d Cir.), cert. denied, 469 U.S. 855, 105 S.Ct. 179, 83 L.Ed.2d 114 (1984)). The scope of our review is narrow because “ ‘the grant or denial of a preliminary injunction is almost always based on an abbreviated set of facts, requiring a delicate balancing [that] is the responsibility of the district judge.’” Frank’s GMC Truck Center, 847 F.2d at 101-02 (alteration in original) (quoting United States Steel Corp. v. Fraternal Ass’n of Steelhaulers, 431 F.2d 1046, 1048 (3d Cir.1970)). Despite the narrow scope of review, “any determination that is a prerequisite to the issuance of an injunction ... is reviewed according to the standard applicable to that particular determination.” Merchant & Evans, 963 F.2d at 633 (alteration in original) (quoting John F. Harkins Co. v. Waldinger Corp., 796 F.2d 657, 658 (3d Cir.1986), cert. denied, 479 U.S. 1059, 107 S.Ct. 939, 93 L.Ed.2d 989 (1987)). Therefore, “‘[djespite oft repeated statements that the issuance of a preliminary injunction rests in the discretion of the trial judge whose decisions will be reversed only for “abuse”, a court of appeals must reverse if the district court has proceeded on the basis of an erroneous view of the applicable law.’ ” Apple Computer, Inc. v. Franklin Computer Corp., 714 F.2d 1240, 1242 (3d Cir.1983) (quoting Donovan v. Bierwirth, 680 F.2d 263, 269 (2d Cir.), cert. denied, 459 U.S. 1069, 103 S.Ct. 488, 74 L.Ed.2d 631 (1982)), cert. dismissed, 464 U.S. 1033, 104 S.Ct. 690, 79 L.Ed.2d 158 (1984). In the final analysis, “[w]e review the district court’s conclusions of law in a plenary fashion, its findings of fact under a clearly erroneous standard, and its decision to grant or deny an injunction for abuse of discretion.” Johnson & Johnson-Merck Consumer Pharmaceuticals, Inc. v. Rhone-Poulenc Rorer Pharmaceuticals, Inc., 19 F.3d 125, 127 (3d Cir.1994) (citations omitted); see also Duraco Prods., Inc. v. Joy Plastic Enter., Ltd., 40 F.3d 1431, 1438 (3d Cir.1994). B. AT & T’s section 43(a) claim 1. Generally The district court focused primarily on whether AT & T had demonstrated a “likelihood of success on the merits” and held that AT & T had not met its burden by a preponderance of the evidence. We, likewise, will focus on the district court’s conclusion that AT & T failed to demonstrate a likelihood of success on the merits. As a threshold matter, this appeal requires us to decide a question of statutory construction, namely, the extent to which federal courts interpreting federal statutes may import intq such statutes common law doctrines of secondary liability. Section 43(a) of the Lanham Act, originally enacted in 1946 and amended substantially in 1988, provides in relevant part that: [a]ny person who, on or in connection with any goods or services ... uses in commerce any word, term, name, symbol or device ... or any false designation of origin, false or misleading description of fact, or false or misleading representation of fact which ... is likely to deceive as to the affiliation, connection or association of such person with another person, or as to origin, sponsorship or approval of his or her goods, services, or commercial activities by another person ... shall be liable in a civil action by any person who believes that he or she is or is likely to be damaged by such act. 15 U.S.C. § 1125(a). By containing such broad language, the Act “proscribes not only trademark infringement in its narrow sense, but more generally creates a federal cause of action for unfair competition.” Duraco Prods., Inc., 40 F.3d at 1438; American Greetings Corp. v. Dan-Dee Imports, Inc., 807 F.2d 1136, 1140 (3d Cir.1986) (citing Williams v. Curtiss-Wright Corp., 691 F.2d 168, 172 (3d Cir.1982)); see also 3 J. Thomas McCarthy, McCarthy on Trademarks and Unfair Competition, § 27.02[1] at 27-13 (hereinafter “McCarthy on Trademarks”). In order to succeed on its claim, AT & T must prove by a preponderance of the evidence that: (1) Winback uses a false designation of origin, as defined in the Act; (2) That such use of a false designation occurs in interstate commerce in connection with goods and services; (3) That such false designation is likely to cause confusion, mistake or deception as to the origin, sponsorship, or approval of Win-back’s goods or services by another person; and (4) That AT & T has been or is likely to be damaged. See 3 McCarthy on Trademarks, § 27.03[l][a] at 27-21. This appeal focuses on a subset of the first prong of the test: whether Winback falsely designated the origin of its services. AT & T does not argue that Winback directly infringed on its rights. Rather, AT & T bases its claim for relief upon the actions of Winback’s sales representatives. It contends that under common law theories of agency including the doctrine of apparent authority, Winback is liable for the infringing actions of its sales representatives. Winback disclaims any responsibility for its sales representatives, over whom it claims to have little control. The statute, by referring to “any person” who infringes on a plaintiffs rights, is silent as to the existence, or the scope, of vicarious liability; the statutory language is directed solely at the infringers themselves. Thus, we are called upon to examine whether the statute permits us to look beyond its contours at all. See, e.g., Central Bank of Denver, N.A. v. First Interstate Bank of Denver, N.A., — U.S. -, -, 114 S.Ct. 1439, 1446, 128 L.Ed.2d 119 (1994) (“With respect [to] the scope of conduct prohibited by [a statute], the text of the statute controls our decision.”); Electronic Lab. Supply Co. v. Cullen, 977 F.2d 798, 806 (3d Cir.1992) (“ Where a statute specifically limits those who may be held liable for the conduct described by the statute, the courts cannot extend liability ... to those who do not fall within the categories of potential defendants described by the statute.’ ”) (quoting In re Equity Corp. of America Sec. Litig., 416 F.Supp. 161, 181 (C.D.Cal.1976)). The questions to be addressed are (1) whether the district court was correct in importing common law doctrines into section 43(a) of the Lanham Act and (2) if so, whether the district court properly applied those doctrines. 2. The effect of Central Bank Generally, “the applicability of common law doctrines in litigation under federal statutes depends on whether those principles advance the goals of the particular federal statute which plaintiffs allege has been violated.” Petro-Tech, Inc. v. Western Co. of North America, 824 F.2d 1349, 1356 (3d Cir. 1987) (citing American Soc’y of Mechanical Eng’rs v. Hydrolevel Corp., 456 U.S. 556, 570, 102 S.Ct. 1935, 1944-45, 72 L.Ed.2d 330 (1982)); O’Neil v. Q.L.C.R.I., Inc., 750 F.Supp. 551, 555 (D.R.I.1990). Of course, the days of a general federal common law have long since passed, see Erie R. Co. v. Tompkins, 304 U.S. 64, 78, 58 S.Ct. 817, 822, 82 L.Ed. 1188 (1938), and courts should be wary about looking outside of the statute itself to expand the scope of liability, lest they accurately be accused of legislating from the bench. Cf. Stomper v. Amalgamated Transit Union, Local 24.1, 27 F.3d 316, 319 (7th Cir.1994) (“Once Congress has legislated, the common-law rules courts apply to fill interstices fall away.”). Thus, when a statute is self-contained, the scope of our interpretation is constrained by the statutory language itself. See, e.g., Central Bank, — U.S. at-, 114 S.Ct. at 1447. Nonetheless, when the importation of common law doctrines will advance the goals of the statute, courts may utilize the doctrines, provided the courts “conform [the] implied remedies to the rules Congress devised for the remedies it authorized expressly.” Stomper, 27 F.3d at 319. Winback implicitly argues that if we import the doctrines of agency and apparent authority into the statute, we would be violating this settled rule of construction and that we would be legislating in areas where Congress has failed to act. Therefore, Winback concludes, AT & T’s argument more properly is made to Congress rather than to the courts. It relies for this proposition on Central Bank, a recent Supreme Court case refusing to find parties liable for aiding and abetting the violation of a federal securities statute. In Central Bank, the Supreme Court considered whether section 10(b) of the Securities Exchange Act of 1934 (the “Exchange Act”), which has been held to create a private cause of action against parties who “commit a manipulative or deceptive act in connection with the purchase of or sale of securities ... extends as well to those who do not engage in the manipulative or deceptive practice but who aid and abet the violation.” Id. at-, 114 S.Ct. at 1443. Examining the language of the statute, as well as the Court’s own tendency to construe narrowly the scope of conduct prohibited by the Exchange Act, the Court concluded that an action cannot be maintained for aiding and abetting securities fraud: “[T]he statute prohibits only the making of a material misstatement (or omission) or the commission of a manipulative act [and this] proscription does not include giving aid to a person who commits a manipulative or deceptive act.” Id. -, 114 S.Ct. at 1148. The language of Central Bank is undeniably broad, and the dissent warned that other mechanisms of common law secondary liability — such as “respondeat superior and other common-law agency principles” — may not survive the majority’s construction of Section 10(b) of the Exchange Act. Id. at -n. 12, 114 S.Ct. at 1460 n. 12 (Stevens, J. dissenting). Nonetheless, we do not believe that the Court’s restrictive reading of the Exchange Act impacts on the determination of the scope of liability under the Lan-ham Act. In Central Bank, the Supreme Court primarily was concerned with broadening the range of unlawful conduct beyond that specifically proscribed by the Act. As the Court framed the issue, aiding and abetting constituted a separate cause of action, and in order to find such liability, the Court would have to imply a private right of action under the statute beyond that which already had been implied. See id. at-, 114 S.Ct. at 1447 (“statutory text controls the definition of conduct covered by § 10(b) [and] ‘the language of Section 10(b) does not in terms mention aiding and abetting.’”) (quoting Brief for Securities and Exchange Commission as Amicus Curiae at 8). Thus, the Court saw the case as involving another in a series of attempts by plaintiffs and the SEC to broaden the statute to prohibit conduct simply not covered by the actual statutory language. See, e.g., Chiarella v. United States, 445 U.S. 222, 235, 100 S.Ct. 1108, 1118, 63 L.Ed.2d 348 (1980) (“When an allegation of fraud [under section 10(b) ] is based upon nondisclosure, there can be no fraud absent a duty to speak”); Santa Fe Indus., Inc. v. Green, 430 U.S. 462, 476, 97 S.Ct. 1292, 1302, 51 L.Ed.2d 480 (1977) (statute does not prohibit “a breach of fiduciary duty by majority stockholders, without any deception, misrepresentation, or nondisclosure” because such an act is not manipulative or deceptive conduct); Ernst & Ernst v. Hochfelder, 425 U.S. 185, 201, 96 S.Ct. 1375, 1384-85, 47 L.Ed.2d 668 (1976) (refusing to expand scope of liability under section 10(b) of Securities Exchange Act beyond knowing or intentional misconduct). Once again, the Court simply refused to expand “the scope of conduct prohibited by the statute.” Central Bank, — U.S. at -, 114 S.Ct. at 1453. The Supreme Court’s wariness therefore rested on the nature of aiding and abetting liability itself. And in fact, aiding and abetting liability is not a well-settled mechanism for imposing civil liability. Rather, “[a]iding and abetting liability traditionally applies to criminal offenses”, see Electronic Lab. Supply Co., 977 F.2d at 805; PetroTech, 824 F.2d at 1356. While it has been borrowed in certain civil contexts, “[precedent, except in the securities area, is largely confined to isolated acts of adolescents in rural society.” Halberstam v. Welch, 705 F.2d 472, 489 (D.C.Cir.1983) (also quoted in Central Bank, — U.S. at-, 114 S.Ct. at 1450). This is because aiding and abetting liability, with its focus on the defendant’s substantial and knowing assistance to the commission of a tort, rests by definition upon acts that encourage a tort rather than acts constituting the tort. See, e.g., Halberstam, 705 F.2d at 481-86 (canvassing aiding and abetting tort cases). By definition then, the act rendered unlawful under an aiding and abetting theory is different than the act rendered unlawful by the underlying tort. By contrast, courts imposing liability on agency theories are not expanding the category of affirmative conduct proscribed by the relevant statute; rather, they are deciding on whose shoulders to place responsibility for conduct indisputably proscribed by the relevant statute. The principal is held liable not because it committed some wrongdoing outside the purview of the statute which assisted the wrongdoing prohibited by the statute, but because its status merits responsibility for the tortious actions of its agent. Cf. Petro-Tech, Inc., 824 F.2d at 1356-58 (discussing aiding and abetting and vicarious liability separately). Indeed, in some instances, liability cannot be imposed without reference to agency principles — a corporation can only act through its agents, and therefore only can be bound through application of agency principles. Moreover, unlike aiding and abetting liability, which in the federal system largely has been confined to securities fraud, agency doctrine, including the theory of apparent authority, has long been a part of the federal system. As long ago as 1928, the Supreme Court applied as a matter of federal common law general principles of agency law. In so doing, it held that “few doctrines of the law are more firmly established or more in harmony with accepted notions of social policy than that of the liability of the principal without fault of his own.” Gleason v. Seaboard Air Line Ry. Co., 278 U.S. 349, 356, 49 S.Ct. 161, 162-63, 73 L.Ed. 415 (1929). More recently, in American Soc’y of Mechanical Eng’rs, Inc. v. Hydrolevel Corp., the Supreme Court began its analysis of whether apparent authority applies in the antitrust context with the premise that “[t]he apparent authority theory has long been the settled rule in the federal system.” Hydrolevel, 456 U.S. at 567, 102 S.Ct. at 1943 (citing Ricketts v. Pennsylvania R.R. Co., 153 F.2d 757, 759 (2d Cir.1946)). In Hydrolevel, the Supreme Court followed the approach of the Restatement (Second) of Agency, and held that “a principal is liable for an agent’s misrepresentations that cause pecuniary loss to a third party, when the agent acts within the scope of his apparent authority.” Id. 456 U.S. at 566, 102 S.Ct. at 1942 (citing Restatement (Second) of Agency §§ 249, 262 (1957); Rutherford v. Rideout Bank, 11 Cal.2d 479, 80 P.2d 978 (1938)). More recently, following earlier precedents, we have recognized respondeat superi- or liability under Title VII of the Civil Rights Act of 1964. Spain v. Gallegos, 26 F.3d 439, 450 (3d Cir.1994). See also Karibian v. Columbia Univ., 14 F.3d 773, 780 (2d Cir.) (“an employer is liable for the discriminatorily abusive work environment created by a supervisor if the supervisor uses his actual or apparent authority to further the harassment, or if he was otherwise aided in accomplishing the harassment by the existence of the agency relationship”), cert. denied, — U.S. -, 114 S.Ct. 2693, 129 L.Ed.2d 824 (1994). And “[fjederal courts have routinely applied [respondeat superior ] principles in fair housing cases and held principals liable for the discriminatory acts of their agents.” City of Chicago v. Matchmaker Real Estate Sales Center, Inc., 982 F.2d 1086, 1096 (7th Cir.1992), cert. denied, — U.S. -, 113 S.Ct. 2961, 125 L.Ed.2d 662 (1993); see also Northside Realty Assocs. Inc. v. United States, 605 F.2d 1348, 1353-54 (5th Cir.1979). Thus, Central Bank’s discussion of aiding and abetting should not be transplanted into the more settled realm of agency law. But beyond this, it is quite clear under Central Bank’s reasoning, the Supreme Court was concerned with the Exchange Act itself under which the private right of action already had been judicially implied. Accordingly, we think that the Court did not intend to overrule settled constructions of other statutes that relied on common law doctrines to determine the scope of liability. See Central Bank, — U.S. at-, 114 S.Ct. at 1444 (“we pa[y] close attention to the statutory text in defining the scope of conduct prohibited by § 10(b)”). Thus, in contrast to the Court’s restrictive reading of the Exchange Act, the Court has endorsed and applied a theory of secondary liability for trademark infringement that comes very close to aiding and abetting. The Court first enunciated the rule over 70 years ago, prior to the enactment of the Lanham Act, when the Court was concerned with constructing and enforcing a common law of unfair competition. William R. Warner & Co. v. Eli Lilly & Co., 265 U.S. 526, 44 S.Ct. 615, 68 L.Ed. 1161 (1924). In that case, the Court held that a manufacturer of a pharmaceutical product could in certain instances be held liable for acts of infringement by distributors and retailers of the product. Relying on the general proposition that “[o]ne who induces another to commit a fraud and furnishes the means, of consummating it is equally guilty and liable for the injury,” id. at 530-31, 44 S.Ct. at 617 (citing Hostetter Co. v. Brueggeman-Reinert Distilling Co., 46 Fed. 188, 189 (C.C.D.Mo.1891)), the Court reached what it saw as a self-evident conclusion: an entity is liable for trademark infringement if it contributes to the infringement. The theory of “contributory infringement”, as it came to be called, survived into the statutory era. As the Supreme Court explained in a case involving section 32 of the Lanham Act: [Liability for trademark infringement can extend beyond those who actually mislabel goods with the mark of another. Even if a manufacturer does not directly control others in the chain of distribution, it can be held responsible for their infringing activities under certain circumstances. Thus, if a manufacturer or distributor intentionally induces another to infringe a trademark, or if it continues to supply its product to one whom it knows or has reason to know is engaging in trademark infringement, the manufacturer or distributor is contribu-torily responsible for any harm done as a result of the deceit. Inwood Labs., Inc. v. Ives Labs., Inc., 456 U.S. 844, 854, 102 S.Ct. 2182, 2188, 72 L.Ed.2d 606 (1982). “The two elements for contributory infringement are thus summed up as (1) supply of a product, and (2) knowledge of direct infringement.” Fonovisa, Inc. v. Cherry Auction, Inc., 847 F.Supp. 1492, 1498 (E.D.Cal.1994). Of course, there is no reason why the doctrine should be confined in application to manufacturers, and indeed, other courts have expanded it beyond that particular origin. See, e.g., Mini Maid Servs. Co. v. Maid Brigade Sys., Inc., 967 F.2d 1516, 1522 (11th Cir.1992) (doctrine could hold franchisor liable for infringing actions of its franchisee when “franchisor explicitly or implicitly encouraged the trademark violations”); Hard Rock Cafe Licensing Corp. v. Concession Servs., Inc., 955 F.2d 1143, 1149 (7th Cir.1992) (landlord of flea market could be liable for its tenant’s sale of an infringing product where the landlord is found to have been “wilfully blind” to the infringing acts); but see Fonovisa, 847 F.Supp. at 1498 (refusing to apply doctrine of contributory infringement “to impose liability on third parties who have never had a traditional role in enforcing the Lanham Act”). 3. Is there agency liability under section 43(a)? The question, then, is whether application of agency theory, including the doctrine of apparent authority, would further the goals of the statute. See, e.g., Hydrolevel, 456 U.S. at 570, 102 S.Ct. at 1944. In Hydrolevel, the Court, finding that “under general rules of agency law, principals are liable when their agents act with apparent authority and commit torts analogous to the antitrust violation presented by this case”, simply looked at the policy behind the antitrust laws to determine whether the doctrine should be applied. Id. at 565-66, 570, 102 S.Ct. at 1942, 1944. Because “apparent authority theory is consistent with the congressional intent to encourage competition”, the Court applied the doctrine. Id. The contributory infringement cases cited above demonstrate that in certain instances, secondary, indirect liability is a legitimate basis for liability under the federal unfair competition statute. There is a good reason for this: the Lanham Act is derived generally and purposefully from the common law tort of unfair competition, and its language parallels the protections afforded by state common law and statutory torts. Thus, the conduct prohibited by section 43(a) of the Lanham Act is even more analogous to common law torts than the antitrust laws at issue in Hydrolevel. The Act federalizes a common law tort. In construing the Act, then, courts routinely have recognized the propriety of examining basic tort liability concepts to determine the scope of liability. See, e.g., Electronic Lab. Supply Co., Inc., 977 F.2d at 806 (section 34(d)(11) of Lanham Act is like a “tort” statute); Hard Rock Cafe, 955 F.2d at 1148 (trademark infringement is a “species of tort” and “we ... have turned to the common law to guide our inquiry into the appropriate boundaries of liability”); David Berg and Co. v. Gatto Int’l Trading Co., Inc., 884 F.2d 306, 311 (7th Cir.1989) (“unfair competition and trademark infringement are tor-tious”); 3 McCarthy on Trademarks § 25.03[1] at 25-34 (“trademark infringement and unfair competition are torts”). We previously have held that the “federal law of unfair competition under § 43(a) is not significantly different from the New Jersey [common] law of unfair competition” and have applied the identical test to both claims. American Greetings Corp. v. Dan-Dee Imports, Inc., 807 F.2d 1136, 1141 (3d Cir.1986); see also American Home Prods. Corp. v. Barr Lab., Inc., 656 F.Supp. 1058, 1061 (D.N.J.1987) (same), aff'd, 834 F.2d 368 (3d Cir.1987). Other courts have ruled similarly. See, e.g., Words & Data, Inc. v. GTE Communications Servs., Inc., 765 F.Supp. 570, 579 (W.D.Mo.1991) (“Missouri common law regarding unfair competition is coextensive with federal law”); Worthington Foods, Inc. v. Kellogg Co., 732 F.Supp. 1417, 1431 (S.D.Ohio 1990) (“an analysis appropriate for a determination of liability under section 43(a) of the Lanham Act is also appropriate for determining liability under the Ohio Deceptive Trade Practices Act”). Therefore, because section 43(a) parallels state tort law and is derived from tort common law, it is self-evident that application of at least some tort concepts of liability will “advance the goals of [the Act].” Petro-Tech, Inc., 824 F.2d at 1356. Applying the analysis to the facts of this case, it is clear that liability based on agency principles is often appropriate. The Lan-ham Act has the broad purpose of “protect[ing] ... competitors from a wide variety of misrepresentations of products and ser-vice_” 20th Century Wear, Inc. v. Sanmark-Stardust Inc., 747 F.2d 81, 91 n. 13 (2d Cir.1984), cert. denied, 470 U.S. 1052, 105 S.Ct. 1755, 84 L.Ed.2d 818 (1985). By expressly creating a private right of action against the infringer, the Act creates a “statutory tort of broad[ ] scope” that “provides a private remedy to a commercial plaintiff who meets the burden of proving that its commercial interests have been harmed by a competitor’s [misrepresentations]”. Sandoz Pharmaceuticals Corp. v. Richardson-Vicks, Inc., 902 F.2d 222, 227, 230 (3d Cir.1990). Here, the parties recognize that AT & T has the right to sue the sales representatives under section 43(a). But, as Winback acknowledges, “it would be inconvenient for AT & T to initiate suit in separate jurisdictions against every independent contractor which it believes violated its intellectual property rights.” Appellee br. at 13-14. The only feasible way for AT & T to assert its federal rights would be to sue the principal, who, if an agency relationship is established, is able to exercise at least some control over its agents, who authorized the sales representatives to enter into contracts on its behalf, and who receives direct financial benefits from those contracts. If the Act prohibited such liability, then infringing actions would continue undeterred, a company would benefit from undeterred unlawful acts, and the statute’s purpose to prohibit unfair competition would go unrealized. “‘[I]t would be unjust to permit an employer to gain from the intelligent cooperation of others without being responsible for the mistakes, the errors of judgment and the frailties of those working under his direction and for his benefit.’” Petro-Tech, 824 F.2d at 1358 (quoting Restatement (Second) of Agency § 219, comment (a) on subsection (1)). Thus, we hold that the district court properly held that agency principles apply to the instant dispute. Nonetheless, our review of the record compels the conclusion that the. district court erred by failing adequately to consider the various theories of agency under which Winback could be responsible for the torts of its representatives. In particular, the district court should have considered (1) whether Winback is liable for its representatives’ acts, despite the fact that the representatives are independent contractors and despite the absence of a master-servant relationship; and (2) whether the representatives, even if not agents, were acting with the apparent authority of Winback. 4. Agency law We now apply agency law to the facts of this ease. “An agency relationship is created when one party consents to have another act on its behalf, with the principal controlling and directing the acts of the agent.” Sears Mortgage Corp. v. Rose, 134 N.J. 326, 634 A.2d 74, 79 (1993) (citing Arcell v. Ashland Chem. Co., 152 N.J.Super. 471, 378 A.2d 53, 65 (Law Div.1977); 2A C.J.S. Agency § 37 (1972); Restatement (Second) of Agency § 1 (1958)). Depending upon the right of control capable of being exercised by the principal over the agent, agents are characterized either as servants or independent contractors. Servants generally are employees of the principal, and are subject to physical control by the principal. As one court has explained the distinction: ‘An agent is a person who represents another in contractual negotiations or transactions aMn thereto. A servant is a person who is employed to perform personal services for another in his affairs, and who, in respect to his physical movements in the performance of the service, is subject to the other’s control or right of control. Persons who render service but retain control over the manner of doing it are not servants.’ Sanders v. Rowan, 61 Md.App. 40, 484 A.2d 1023, 1028 (1984) (quoting Globe Indem. Co. v. Victill Corp., 208 Md. 573, 119 A.2d 423, 427 (1956)). Thus, if “ ‘the employer assumes the right to control the time, manner, and method of executing the work, as distinguished from the right merely to require certain definite results in conformity to the contract,’ ” a master-servant agency relationship has been created. Stewart v. Midani, 525 F.Supp. 843, 845 (N.D.Ga.1981) (applying Georgia law) (quoting Blair v. Smith, 201 Ga. 747, 41 S.E.2d 133, 135 (1947)). If, however, the agent is not subject to that degree of physical control, but is only subject to the general control and direction by the principal, the agent is termed an independent contractor. Id. at 846; see also Nazworth v. Swire Florida, Inc., 486 So.2d 637, 638 (Fla.Dist.Ct.App.1986) (“ ‘independent contractor’ is a term which is antithetical to the word ‘servant’, although not to the word ‘agent’ ”) (quoting Restatement (Second) Agency section 14N, Comment (a)). Thus, all agents who are not servants are “independent contractors.” Moreover, all non-agents who contract to do work for another are also termed “independent contractors”. For example, a person who contracts to build a swimming pool for another is the latter’s independent contractor. There are, then, agent independent contractors and non-agent independent contractors. Such distinctions matter because the scope of the employer’s liability for the torts of its representatives depends almost exclusively on how the relationship is characterized. “If the principal is the master of an agent who is his servant, the fault of the agent, if acting within the scope of his employment, will be imputed to the principal by reason of respon-deat superior.” Baldasarre v. Butler, 132 N.J. 278, 625 A.2d 458, 464 (1993) (emphasis added) (quoting JMB Enter. v. Atlantic Employers Ins., 228 N.J.Super. 610, 550 A.2d 764, 767 (App.Div.1988)). On the other hand, “the principal [generally] is not vicariously liable for the torts of the independent contractor if the principal did not direct or participate in them.” Baldasarre, 625 A.2d at 465 (emphasis added); Sanders, 484 A.2d at 1028-29 (“where the agent is not a servant, the principal is not liable for the agent’s negligent conduct ‘unless the act was done in the manner authorized or directed by the principal, or the result was one authorized or intended by the principal.’ ”) (citations omitted); Nazworth, 486 So.2d at 638 (“The general rule ... is that an owner, employer, or contractee will not be held liable for the torts of an independent contractor or of the latter’s employees committed in the performance of the contracted work.”) (citations omitted). As the New Jersey Supreme Court has explained, the independent contractor is “ ‘characterized by the attributes of self-employment and self-determination in the economic and professional sense’ ”. Baldasarre, 625 A.2d at 465 (quoting Rokos v. State, Dep’t of Treasury, 236 N.J.Super. 174, 564 A.2d 1217, 1220 (App.Div.1989)). Since the employer ‘has no right of control over the manner in which the work is to be done, it is to be regarded as the contractor’s own enterprise, and he, rather than the employer is the proper party to be charged with the responsibility for preventing the risk, and administering and distributing it.’ Baldasarre, 625 A.2d at 465 (quoting Prosser and Keeton on Torts, § 71). The district court found that the sales representatives are independent contractors and therefore Winback could not be liable for their infringing acts. AT & T’s arguments against this finding can be summed up as follows: (1) the district court erred by failing to categorize the sales representatives as employees or servants of Winback; (2) the district court failed to consider whether the representatives were agent independent contractors or non-agent independent contractors; (3) the district court failed to consider whether Winback had created an apparent master-servant relationship such that Win-back should be held liable for the torts of its sales representatives; (4) Winback should be held liable at any rate. We will address these arguments in turn. a. Servants or independent contractors In reaching its conclusion that Win-back’s sales representatives are independent contractors, the district court relied almost exclusively on Baldasarre. In that ease, the plaintiff had sought to hold a purchaser of land liable for his attorney’s alleged misrepresentations. In denying relief, the Supreme Court of New Jersey reasoned: Attorneys generally are not subject to their clients’ actual control or direction. Indeed, most clients have an attorney because they are unfamiliar with the law and want an attorney to guide them through the intricacies of that field. As professionals, attorneys are deemed responsible for their own acts, and, as in this ease, most clients have legal recourse against the attorney and his law firm for their actions. Baldasarre, 625 A.2d at 465. Therefore, the Court concluded that “[a]n innocent client should not be held vicariously liable for the wrongful conduct of his or her attorney against the attorney’s other clients if the client does not direct, advise, consent to or participate in the attorney’s improper conduct.” Id. at 465. The district court in this case analogized as follows: [T]he level of joint activity between [Win-back] and Inga and the sales representatives is similarly minimal and peripheral to the nuts and bolts of the business of marketing and promoting. Furthermore, as detailed above, no proof was submitted to the Court to establish that [Winback] or Inga advised, consented to or participated in the alleged misrepresentations. Accordingly, plaintiff has failed to establish sufficient proof that the sales representatives are any more than independent contractors. 851 F.Supp. at 623. We hold that the district court correctly concluded that the sales representatives are independent contractors. The district court found that Winback employs no marketing employees on its own, and that the sales representatives “play an integral role in the success of [Winback], financially and otherwise, in that all sales are conducted through these agencies and individuals.” 851 F.Supp. at 626. Nonetheless, the district court correctly recognized that Winback exercises minimal control over the manner in which the representatives perform their work, and no control at all even over whether the representatives choose to market their company. Moreover, the representatives work for any number of companies at the same time, are paid purely based on the results they obtain, and operate their own businesses with their own expenses. The fact that Winback attempted to police the representatives to prevent misrepresentations does not change our result. “[A]n employer does not transform an independent contractor into a servant merely because he wishes to supervise the project as it transpires.” Brady v. Ralph Parsons Co., 308 Md. 486, 520 A.2d 717, 731 (1987). Therefore, the district court properly found that the sales representatives were independent contractors. However, the court erred by stopping at that point. The district court failed to determine whether the sales representatives were agent independent contractors or non-agent independent contractors. b. Agent independent contractors? In this regard, we first must address the scope of the district court’s findings. Although the district court appeared to conclude that the representatives are non-agent independent contractors, a close reading of the decision reveals that the court actually-found only that the representatives were non-serocmi independent contractors. For one thing, the court referred to “the distinctions between employees or agents and non-employees or independent contractors,” implying that once a representative is termed an independent contractor it is by definition a non-agent. Winback, 851 F.Supp. at 626. Moreover, in determining that the representatives were independent contractors, the court used precisely the factors normally used to distinguish between servants and independent contractors: the principal’s right of physical control, the place where the representatives work, the method of payment, the fact that the representatives had their own business enterprises. See Warren A. Seavey, Agency, § 84 at 142 (1964) (hereinafter “Seavey”) (“the relation of master and servant is indicated by the fact that the employee is given a salary and is employed for a considerable period; that he is using an instrumentality of the principal on his premises; that the work is unskilled, usually supervised; that the one employed does not have a distinct business”). The district court’s failure to make the additional finding is crucial, because while generally principals are not liable for the torts of their independent contractors, the common law is littered with exceptions: [TJhere is a range of tortious conduct on the part of an agent that may bind the principal and subject him to liability even where the agent is not a servant, where the act was not done in the manner authorized or directed by the principal, and where the result was not authorized or intended by the principal. Sanders v. Rowan, 484 A.2d at 1029. A principal is not generally liable for physical torts committed by its independent contractor-agent, but a principal will be held liable for the independent contractor-agent’s misrepresentations “upon matters which the principal might reasonably expect would be the subject of representations, provided the other party has no notice that the representations are unauthorized.” Id. at 1029 (quoting Restatement (Second) of Agency § 258); see also Nagels v. Christy, 830 S.W.2d 754, 757 (Mo.1959) (principal liable for misrepresentations by independent contractor sales agent) (citing cases). As one commentator has written: Where an agent is authorized or apparently authorized to conduct a transaction, and the other party is unaware of any limitation upon the agent’s authority, a problem similar to that of the limits of the scope of employment by a servant arises. The difficulties are best seen in the cases of selling agents. Their principals have been held liable for the unauthorized and untrue statements as to the capacity of the machine sold, the age of a second-hand automobile, the construction and material used in building a house, the income from property, the amount of taxes due upon it, the extent of coverage of insurance, the intent of the manufacturer not to disturb a distributorship awarded by it to the plaintiff. Seavey, § 92 at 163. Although liability at common law generally was limited to actions by the purchaser for deceit, we see no reason why the doctrine should not be transplanted to the area of unfair competition. The basis for the common law exception is the injustice in allowing a principal to place agents in the marketplace, to allow the agents to complete contracts on the principal’s behalf, to profit from the agents’ misrepresentations, and then to disclaim liability for the agents’ actions while benefitting from the fraud. The theory relies on the distinction between torts of misrepresentation that benefit the defendant, and torts such as negligently injuring a passerby while driving a car, from which the defendant does not profit at all. Moreover, as the New Jersey Supreme Court has noted, it is appropriate for courts to consider “awareness of the risk and the element of foreseeability of loss in their consideration of liability based on agency principles.” Sears Mortgage Corp., 634 A.2d at 83. Correctly characterized, then, the doctrine simply states a circumstance in which the principal justly is held responsible for the torts of its independent contractor-agent. We hold, then, that when a principal authorizes its independent contractor agent to conduct and conclude a transaction with third parties on the principal’s own behalf, and the principal benefits financially from the contracts, the principal will be liable in an action brought pursuant to section 43(a) of the Lanham Act based on the agents’ foreseeable infringing actions upon which it would be reasonable for the third party to rely, provided the third party has no notice that the representations are unauthorized. Of course, it would be unfair for a principal to be liable for all misrepresentations of its agent independent contractors. Thus, we include the requirements that the misrepresentations be foreseeable and that reliance be reasonable. In considering whether the infringing actions were foreseeable, the district court should consider all of the surrounding circumstances. For instance, if the principal went to great lengths to ensure that the agents knew not to make certain representations, such representations, if made, may be found to be unforeseeable. But if, at the same time, the principal gave the agents carte blanche to hold themselves out as the principal itself, then such infringing actions may become foreseeable, notwithstanding the principal’s efforts at policing the agents. The point, of course, is to hold the principal liable when it is just to do so, but still to encourage the principal to police the agents enough so as to avoid liability. This is the type of balancing the district court must undertake in the first instance. Professor Seavey’s cautionary observations about reliance are also apt: It is difficult to suggest a limitation upon the power of a selling agent to bind the principal if the statements are relevant to the transaction which the agent is authorized to conduct ... A working rule would be the limitation of liability to statements concerning matters as to which the principal might think the agent, or any agent, might misrepresent in forwarding their joint interests. There must be limits. The seller of a New England farm should not be liable to a credulous buyer for tort damages if the agent were to represent that the land to be sold contained oil or gold. Seavey, § 92 at 164. Because the district court failed to address whether the representatives were agents or non-agents, and therefore failed to consider these questions, we must remand the case for further fact findings and renewed application of the law to the facts. Upon remand, then, the district court first must determine whether the sales representatives were agent independent contractors or non-agent independent contractors. The Restatement defines a non-agent independent contractor as follows: A person who contracts to accomplish something for another or to deliver something to another, but who is not acting as a fiduciary for the other is a non-agent contractor. He may be anyone who has made a contract and who is not- an agent. - The term is used colloquially to describe builders and others who have contracted to accomplish physical results not under the supervision of the one who has employed them to produce the results. Restatement (Second) Agency § 14N, Comment (b). Thus, the district court should assess whether the representatives are analogized better to a firm that contracts to perform a particular, discrete task, such as to build a swimming pool, or to a party who is empowered to speak for another and bind the other in contracts. In making this determination, the facts analyzed by the district court and adduced at the hearing are certainly relevant. While the district court should focus on the level of control exercisable by Winback over the manner in which the sales representatives market its product, it should not emphasize physical control (as it properly did in considering whether the representatives were servants). Inga’s testimony that he attempts to police the representatives is certainly relevant to this inquiry, particularly if Winback authorizes the agents to represent themselves as Winback. If the district court finds that the sales representatives are agents, it then must proceed to determine whether they committed infringing acts and whether, under the test we
