RYAN, Chief Judge. This civil' antitrust suit was filed by the United States of America under Section 4 of the Sherman Act, 15 U.S.C.A. § 4 to prevent and restrain alleged violations by the defendant of Sections 1 and 2 of the Act, 15 U.S.C.A. §§ 1, 2. The suit concerns only the United States trade and commerce arising from the importation into the United States of a particular type of household sewing machine known as the “machine-carried multicam zigzag machine.” Many of the relevant and material facts were stipulated by the parties prior to trial following extensive informal hearings held with counsel. The very competent senior attorneys and the junior associates appearing both for the Government and for the defendant gave evidence of their great ability, conscientious application and industry, and zealous advocacy. They were most cooperative and helpful; for this, they have the thanks of the Court. I. THE ISSUES PRESENTED. The complaint alleges that, beginning in at least 1956 and continuing up to December 22, 1959, the date of the filing of the complaint, the defendant and the alleged co-conspirators had been engaged in an unlawful combination and conspiracy to restrain and monopolize; and that the defendant had unlawfully attempted to monopolize interstate and foreign trade and commerce in the importation, sale and distribution of household automatic zigzag sewing machines. The acts alleged to have been committed by the defendant pursuant to the alleged conspiracy and attempt are: (1) the acquisition by the defendant from the alleged co-conspirator Gegauf of two United States patent applications covering automatic zigzag sewing machines; (2) the making of separate agreements with the alleged co-conspirators Gegauf and Vigorelli to insure the granting, with respect to specified patents, of the broadest possible patent claims to each other for the purpose of excluding foreign automatic zigzag sewing machines; (3) the filing of infringement suits and proceedings before the Tariff Commission by the defendant asserting the patent rights assigned to it by Gegauf in conjunction with its own patent rights to exclude the importation into the United States of automatic zigzag sewing machines of foreign manufacture; (4) the action by defendant, in conjunction with the alleged co-conspirators, determining what European manufacturers would be permitted to export foreign made automatic zigzag sewing machines to the United States; and (5) the making by the defendant of a non-aggression cross-licensing agreement with Messersehmitt and the subsequent acquisition by the defendant of the United States Messersehmitt patent application which was the subject of the cross-license agreement, for the purpose of excluding foreign made automatic zigzag sewing machines. The Government does not charge that the acquisition by Singer of three other United States patents — the Harris reissue, Johnson, and Perla, which are later discussed — was unlawful. On the contrary, it concedes that they were lawfully acquired. It is the acquisition of these two Gegauf United States patents, known as Gegauf No. 1 and No. 2, which is claimed by the Government to be unlawful. It is contended that they were acquired by Singer pursuant to the alleged conspiracy and with a purpose to use them in conjunction with the above three lawfully acquired patents to exclude competition. The Government also contends that the Singer “401” machine was fully protected under a Gegauf license and the Johnson patent. From these acts, it is alleged, have flowed the following results: (1) United States importers, distributors and retailers, dealing in household automatic zigzag sewing machines of foreign manufacture, have been precluded from importing, distributing and selling these machines in a market free from unlawful restraints; (2) defendant has been able to acquire and maintain a position of domination and control in the manufacture, sale and distribution of household automatic zigzag sewing machines in the United States; and (3) consumers have been deprived of the opportunity of purchasing household automatic zigzag sewing machines in a free and competitive market. To dissipate these effects, the Government prays that the defendant be enjoined from continuing to carry out the alleged conspiracy and attempt to monopolize and from using its patents and patent rights to effectuate the alleged conspiracy. The main thrust of the defense lies in the contention that all the complained-of activities of Singer were lawful and were done to accomplish a lawful purpose. Defendant maintains that they were initiated and carried out solely to insure Singer’s ability to lawfully protect the manufacture and sale of its “401” sewing machine in the United States and of its “319” sewing machine outside the United States. The specific issues presented are: (1) Was there an unlawful conspiracy among the alleged conspirators to restrain or exclude competition in the trade and commerce involved?; (2) Did Singer attempt to monopolize this trade and commerce?; and (3) Were the agreements entered into between the parties or any of their provisions per se violations of Sections 1 or 2 of the Sherman Act? The Government did not call any witnesses on its ease in chief; it called four witnesses on rebuttal; it offered in evidence 210 exhibits, documentary and physical, during the trial. Defendant called ten witnesses on its case in chief and two in rebuttal; it offered 202 documentary and physical exhibits. After consideration of all this evidence, we make the following findings of fact. II. FINDINGS OF FACT. A. Description of defendant and of others. The sole defendant named is The Singer Manufacturing Company (hereinafter Singer), a New Jersey corporation with its principal place of business in this district. Singer manufactures household sewing machines, including machine-carried multi cam zigzag sewing machines, which are particularly involved in this suit. It sells these machines in the United States through a wholly-owned subsidiary, the Singer Sewing Machine Company, and in various foreign countries through independent distributors. The alleged co-conspirators named in the complaint are: Fritz Gegauf, A. G., Bernina Nahmaschinen Fabrik (hereinafter Gegauf), a Swiss corporation with its principal place of business in Steckborn, Switzerland. Gegauf manufactures household sewing machines in Switzerland, including automatic zigzag sewing machines, and exports some of these machines to various countries including the United States. Arnaldo Vigorelli, S. p. A. (hereinafter Vigorelli) is an Italian corporation, with its principal place of business in Pavia, Italy. Vigorelli manufactures household sewing machines in Italy, including automatic zigzag sewing machines, and exports some of these machines to various countries, including the United States. Although not named as an alleged co-conspirator, there was some evidence presented concerning Messerschmitt, A. G. with whom Singer at times had patent negotiations and dealings. Messerschmitt is a German corporation, engaged in the manufacture and sale of household sewing machines, including zigzag sewing machines. B. A brief description, of household zigzag sewing machines and their operation. Some sewing machines are designed and sold for use principally by housewives for personal and family sewing needs; other machines are produced to meet the requirements of industrial and commercial use. The straight stitch type of household sewing machine comprises three basic devices, namely, a thread-carrying needle which reciprocates in a vertical direction but does not move transverse to the direction of the work feed; a looptaker which, cooperating with the needle, forms a straight line of stitches; and a mechanism which feeds the work to be stitched between such needle and looptaker. These three devices are driven in synchronism by an electric motor or by an operator using a treadle, handcrank, or similar mechanism. The speed of the machine, the length of the stitches and the direction of the feed may be varied by the operator. The zigzag stitch machine has all of the features and functions of a straight stitch machine and may be operated as a straight stitch machine. In addition, the needle may be shifted back and forth laterally of the normal direction of the work feed, from zero to maximum, within the field of lateral throw of the needle, from a fixed neutral position of non-vibration in the center of such field of throw, so as to produce stitches that follow a zigzag path. The size and shape of the pattern of the zigzag stitch may be altered by varying the amplitude of the lateral needle movements and the amplitude and/or direction of the work-feeding movements. Mechanism may be provided for fixing a neutral position of nonvibration of the needle at either the center or at either side of the field of the lateral throw of the needle and for controlling the lateral throw of the needle within such field, from zero to maximum, either across a center line through such field or from either side of such field. Mechanism may also be provided, whereby the needle can be laterally vibrated through predetermined patterns of movement modifying the zigzag stitch path, with the result that stitches may be made having various ornamental configurations other than plain zigzag. There are three general types of household zigzag sewing machines: 1. The manually-operated zigzag machine — a household sewing machine which, in addition to straight stitches, produces continuous plain zigzag stitches and, by manual manipulation, during the operation of the machine, of a handle or lever located on the exterior of the machine, will also produce various ornamental and functional zigzag stitch patterns. 2. The Replaceable Cam ZigZag Machine — a household sewing machine which, in addition to straight stitches, produces without any artistry on the part of the operator, various ornamental and functional zigzag stitch patterns, the preselection of which must be made by the user through the manual removal from the machine of one or more cams and the manual replacement of such cams or cams by one or more substitute cams having cam configurations • different from the replaced cams. 3. The Machine-Carried Multiple Cam Zigzag Machine — a household sewing machine which, in addition to straight stitches, produces without any artistry on the part of the operator, various ornamental and functional zigzag stitch patterns, the preselection of which must be made by the user through a device such as a dial, handle or knob, located on the exterior of the machine, which affects a relative shifting of cam tracking means and a group of machine-carried cams, each having cam configurations different from the other cams. To properly and efficiently operate any household sewing machine, including a zigzag stitch machine, the machine must first be equipped with needle and bobbin threads. Three adjustments must be made to insure that the machine will sew with the requisite thread tension, stitch length and work pressure. During the operation of the machine, the operator must synchronize the speed of the machine to the feed of the material sewn to insure that the stitches will be formed in the desired area of the work material. With each of the three general types of household zigzag sewing machines the operator must in addition make a preselection through a control device determining the width of the zigzag stitch to be produced. With a manually operated machine the zigzag stitch pattern may be varied by the manual manipulation of the stitch width control during machine operation, the results obtained varying with the artistry and skill of the operator. With the replaceable cam and machine-carried multiple cam machines the zigzag stitch pattern is predetermined by the configuration of the particular cam used, which cam in each instance is selected by the operator, by, in the case of the replaceable cam machine, the manual replacement of one cam with another cam and, in the case of the machine-carried multiple cam machine, by the manual use of a dial, handle or knob to select one of a plurality of machine-carried cams. Multicam, replaceable cam and manually operated zigzag sewing machines are not necessarily of corresponding quality, ■either as compared with zigzag sewing machines of the same type or as compared with zigzag sewing machines of a different type. A relatively high priced manually operated machine may be of superior quality to a relatively low priced multicam machine, a relatively low priced replaceable cam machine, or a relatively low priced manually operated machine. The price of the machine, regardless of type, in part depends upon the attachments or appurtenances which may or may not be part of such machine, and ■other factors. Thus, the price may be influenced, as with other commercial products by the reputation of the manufacturer, the availability of service and parts, the available financing arrangements, the instructions as to the use of the sewing machine, type and extent of guarantee, cost of manufacture and distribution, the location and type of shop at which the machine is sold, and the promotion and advertising expenditures. C. Description of the patents. There are five United States patents and one United States patent application which the Government contends are relevant to the wrongful acts charged. Each of these patents and the one patent application is owned by Singer; each discloses a machine carried multicam sewing mechanism. They are as follows: 1. Gegauf Patent No. 2,832,302— application filed May 29, 1953 and patent issued April 29, 1958 (called in this suit Gegauf I). 2. Harris Reissue Patent No. Re. 24,370 — original Harris Patent No. 2,-693,778 issued to Carl Harris on November 9, 1954. Harris Reissue Patent application filed June 16, 1955 and reissue patent issued October 8, 1957. 3. Johnson Patent No. 2,862,468— application filed November 29, 1954 and patent issued December 2, 1958. 4. Perla Patent No. 2,810,360 — application filed December 8, 1954 and patent issued October 22, 1957. 5. Gegauf Patent No. 2,877,726 — divisional application filed December 2, 1957 and patent issued March 17, 1959 (called in this suit Gegauf II). 6. Messerschmitt Application No. 548,481 — application filed November 22, 1955. 1. Gegauf No. I — Patent No. 2,832,302. This patent claims the concept, inter alia, of a mechanism comprising a series of rotary cams having a common axis and a single retractable cam follower, shiftable relative to each other lengthwise of the common cam axis, in order to select a particular cam, but only one cam at a time, for controlling the lateral needle movement. Such a mechanism can produce only as many different zigzag stitch patterns as it has cams, i. e., one for each cam. The Government stipulated that the Singer 401 machine is covered by this patent. 2. Harris Reissue Patent No. Re. 24,370. Reissue Claims 1 through 4 allowed in the Harris Reissue Patent were also allowed in the original Harris Patent No. 2,693,778; these claims do not relate to a multicam mechanism. Eight proposed reissue claims were rejected by the Patent Office. This resulted in a series of amendments, substitutions and rejections of claims until, on May 16, 1956, Singer substituted Claim 22, a limited version of the original Application Claims 5, 7 and 8 taken in combination. On August 22, 1956, this substituted Claim 22 was placed in interference with the United States Gegauf patent application Serial No. 358,377, but subsequently it was allowed by the Patent Office as Claim 1 in Gegauf patent (Gegauf I) No. 2,832,302, issued April 29, 1958. All other substituted claims placed in the reissue application were rejected except Claims 23, 24 and 25; these three substituted claims were allowed in Harris Reissue Patent No. Re. 24,370 as Reissue Claims 5, 6 and 7. Harris reissue allowed Claim 5 includes the limitation, inter alia, of a series of rotatable cams having a common axis with each cam being shiftable lengthwise of the common cam axis with respect to the cam follower in order to select a particular cam. Harris reissue allowed Claim 6 includes the limitation, inter alia, of a series of rotatable cams having a common axis and a cam follower shiftable relative to each other, lengthwise of the common cam axis, in order to select a particular cam, used in combination with a constantly rotatable cam. Harris reissue allowed Claim 7 includes the limitation, inter alia, of a series of rotatable cams having a common axis and a cam follower shiftable relative to each other lengthwise of the common cam axis, in order to select a particular cam used in combination with a particular type of cam follower retracting means. The parties have stipulated that Harris Reissue Patent No. Re. 24,370 discloses a machine which is covered by Claim 1 of Gegauf Patent No. 2,832,302 (Gegauf I). 3. Johnson Patent No. 2,862,468. This patent claims a concept, inter alia, of a mechanism comprising a stack of rotary cams and two cam followers, either of which can track any one cam or in combination can track any two cams simultaneously whereby information from such cam or cams can be utilized to control the lateral movements of the needle. Thus, as the Johnson mechanism has the ability to take information from two cams and combine that information to develop a stitch, it can produce a number of zigzag stitch patterns which far exceeds the number of cams. 4. Perla Patent No. 2,810,360. This patent claims the concept, inter alia, of a mechanism comprising a series of rotary cams with each cam being provided with its own cam follower constrained to engage its associated cam only and with each cam follower being provided with its own individual handle so that each follower can be manually thrown in and out of operative engagement with its associated cam. The cam followers may be used singly to track one cam or in combination to track and combine intelligence from any two cams whereby the information from such cam or cams is utilized to control the lateral movement of the needle. 5. The Gegauf No. 2 — Patent No. 2,877,-726. The Gegauf No. 2 patent claims the concept, inter alia, of a mechanism comprising a series of rotary cams with each cam being provided with its own cam follower constrained to engage its associated cam only, whereby any cam, but only one cam at a time, may be individually selected for controlling the lateral needle movement. Thus, the Gegauf II mechanism can transmit information from any one cam at a time but cannot combine intelligence from two or more cams. 6. Messerschmitt Application No. 548,-481. The Messerschmitt application claimed, inter alia, the concepts of (a) a series of rotary cams with each cam being provided with its own cam follower constrained to engage its associated cam only, whereby any such cam may be individually selected for controlling the lateral needle mechanism and with each cam follower provided with its own individual handle, so that each follower can be manually thrown into and out of operative engagement with its associated cam; and (b) a series of rotary cams with each cam being provided with its own follower to control the work feed by a selected cam. The concept set forth in (a) is the same concept claimed in the Singer United States Perla patent. D. Introduction of zigzag sewing machines into United States and the development of Singer’s 306, 319 and 401 machines. Users of industrial sewing machines, both in the United States and abroad, employed zigzag sewing machines prior to 1900. The known art at that time is illustrated by Leilich United States Patent No. 386,252, issued July 17, 1888, which disclosed an ornamental zigzag stitch sewing machine. This machine had two replaceable cams — one imparted lateral zigzag movement to the needle; the other controlled the amplitude of the work-feeding movement; these cams could be replaced by other cams giving the operator a choice of ornamental stitches. The first Singer zigzag stitch sewing machine manufactured especially for use in the home was the model “206” machine; importation and sale of this machine in the United States commenced in 1951. The “206” machine was manufactured by Singer in its German plant under its Tiesler patent from approximately 1934 to the opening of World War II; later, commencing in 1949, similar machines were manufactured in the Singer factory in Scotland. The “206” was of the manually operated zigzag type with built-in rotating cam; it did not have the replaceable cam of the earlier Leilich. In the “206”, by manual manipulation during the stitching cycle the throw of the cam could be modified and the amplitude of the zigzag stitch varied. In 1948 shipments of an Italian-made “Necchi” zigzag stitch machine (manually operated) first came to the United States. The sales of these “Necchi” machines commercially demonstrated by 1951 that a definite market in a household type zigzag sewing machine existed in the United States. The “Elna” zigzag machine (replaceable cam) was introduced in the United States in 1952. This machine, as the Leilich machine, had two rotary cams and two cam followers. The two cams of the “Elna” machine were replaceable by other cams so that a number of stitch patterns could be produced. Ralph E. Johnson, a member of Singer’s Experimental Department in the Elizabethport, New Jersey plant, commenced work on the development of a household zigzag machine and completed a design of a new machine on April 29, 1953. This design is embodied in the Singer Class 401 machine. The Class 401 machine (machine-carried multiple cam) incorporates a stack of rotary cams and a pair of cam followers, movable lengthwise of the axis of the cam stack, either of which can track any one cam or in combination can track any two cams, whereby information from such cam or cams can be utilized to control the lateral movements of the needle. The Class 401 machine is disclosed in the Johnson U. S. Patent No. 2,862,468 (supra). The design of the Class 401 machine required the manufacture of a new sewing machine. It took Singer four years to develop and to produce the necessary manufacturing and assembly tools so as to permit manufacture of the machine in an efficient and economical manner. The Class 401 machine was placed on the market in June 1957. On March 9, 1953 Martin R. Perla and Edward Koenig, members of Singer’s Experimental Department in Bridgeport, Connecticut plant, were directed to design and develop an improved Class 206 machine, which was to incorporate a replaceable cam. The design of this machine was completed by March 25, 1953 and is embodied in the Singer Class 306 machine (replaceable cam). This design eliminated the cam of the Class 206 machine and superimposed on such machine a zigzag mechanism having a rotary removable cam, otherwise leaving the Class 206 machine substantially in its then existing form. Manufacture and sale of this Class 306 machine was started in the United States and abroad in 1954 and a substantial number of said machines were sold in the United States until 1956 when manufacture, but not sale, of it in the United States was stopped and manufacture of a new Class 319 machine was commenced both abroad and in the United States. The Class 306 machine continues to be manufactured and sold abroad. On April 1, 1954, Martin R. Perla was also directed to design and develop an improved Class 306 machine, which- incorporated a multiple cam arrangement in lieu of the replaceable cam of the Class 306 machine. This design was incorporated in the Singer Class 319 machine. The Class 319 machine (machine-carried multiple cam) incorporates a built in stack of cams, each with its own follower. The cam followers may be used singly or in combination to track one or more selected cams, and to combine intelligence from two or more cams, whereby the information from such cam or cams is utilized to control the lateral movements of the needle. The Class 319 machine is disclosed in the Perla Patent No. 2,810,-360 (supra). The production of this machine was commenced on November 18, 1955 and it was put on sale in 1956, both in the United States and abroad. Manufacture of the Class 319 machine was discontinued in the United States in 1957 when it was superseded by the Class 401 machine. The Class 319 machine continues to be manufactured and sold abroad. In September 1953, the Italian firm of Vigorelli introduced in the United States a multi-cam zigzag stitch sewing machine. The Vigorelli machine incorporated a unitary stack of removable rotary cams, a single cam follower, movable lengthwise of the axis of the cam stack, for tracking any one of such cams, and means for transmitting the motion of the follower to the needle. This involved two ideas. The first idea comprised the concept of utilizing, in combination, a replaceable cam, a cam follower and a means to transmit the motion of the cam follower to the needle bar for the purpose of controlling the lateral needle vibration, in accordance with the shape of the cam, which motion transmitting means included a manually operable mechanism for adjusting and varying the amplitude of such lateral needle vibrations and for determining the neutral position of non-vibration of the needle. This idea was incorporated in the Singer 306 design. The second comprised the concept of utilizing, in combination, a plurality of cams, cam following means and means to transmit the motion of the cam following means to the needle bar for the purpose of controlling the lateral needle vibration in accordance with the shape of any cam, which motion transmitting means included a manually operable mechanism for engaging the cam following means with any one of the cams. This idea was incorporated in the Singer 319 and 401 designs. The first Japanese-made multi-cam zigzag stitch machine was introduced in the United States in September 1954 by Brother International Corporation. This machine, as the Singer 401 and the Vigorelli machine, incorporated a plurality of rotary cams and a single cam follower which could be engaged with any one of the cams for laterally vibrating the needle through a predetermined pattern of movement. In April 1955, Singer first learned that Vigorelli had introduced into the United States a modified form of its multi-cam machine. This modified form differed from the first machine in that in the modified form the single cam follower was adapted not only to engage any one of the cams but in addition to engage any two adjacently disposed cams, which provided an additional variety of ornamental stitches. This idea of taking information from two cams at the same time was embodied in the Singer “401” and “319” machines. E. The sewing machine industry in the United States and Singer’s position in it. Directly after World War II household straight stitch sewing machines were manufactured in the United States by White Sewing Machine Corporation, Free Sewing Machine Company, Inc., The Bell Manufacturing Corporation, Burtman Electric Company, Gelman Manufacturing Company, Inc., and The New Process Gear Company, as well as defendant Singer. By 1959, with the exception of The New Process Gear Company, which manufactures only straight stitch sewing machines on specifications and orders from a single domestic customer, defendant Singer was and now is the sole manufacturer of all household sewing machines made in the United States. During the period 1948 to 1959, importations of household sewing machines, including zigzag machines, from Japan grew from 3,000 machines to 1,100,000 machines; and importations from Europe from 2,500 to 100,000. The only sale and distribution in the United States of sewing machines, including zigzag machines, other than those of defendant and New Process Gear Company, are of machines imported into the United States. White Sewing Machine Corporation discontinued its manufacturing operations in the United States in 1957. According to the White annual report published for the year 1957: Both White and Sears Roebuck & Company had been fighting a side by side but losing battle, over the preceding five or six years, in trying to sell White’s lines of sewing machines made in the United States in competition with foreign-built imports. When Sears discontinued selling the White machines and started importing machines for distribution by Sears, it was obvious that White had no chance of supporting its sewing machine manufacturing facilities. Confronted with this situation, the White management decided to have its lines of sewing machines produced for it in Japan and Germany, and to dispose of its principal sewing machine manufacturing facilities. Most of the sewing machines, including zigzag sewing machines, imported from Europe are complete machines, consisting of head (mechanism of machine), motor, wiring, lights, equipment and appurtenances. Those imported from Japan prior to 1959 consisted only of the “head” —that is, the mechanism of the machine. In 1959, Brother and in 1960 Transworld Industries, two of the largest Japanese importers, began importing heads to which there had been added in Japan the motor, lights and wiring. To the head there is added in the United States, by importers or distributors, carrying cases, cabinets, equipment and appurtenances and, where not already so equipped, motor, wiring and lights. Indeed, some of the various items may also be imported into this country. The assembled units are distributed principally through (1) department stores and mail-order houses, which order directly from distributors or factories in Japan or from distributors in the United States, and (2) wholesale distributors who import the machines directly or purchase them from importers and sell them to retail dealers. Some of these wholesale distributors, including Brother and New Home, two of the largest distributors, are subsidiaries of the two largest Japanese manufacturers and the sole distributors for particular Japanese manufacturers. Most of the retail dealers of imported Japanese and European zigzag machines throughout the United States determine and fix their own list prices for machines handled by them and the actual prices at which they sell such machines, with the result that the same machine may have different list prices and may be sold at different prices in different shops. The price at which such a machine may be sold is generally determined by bargaining at the dealer’s shop, and may be sold at the list price or for an amount off the list price. Dealers’ list prices for a particular European-made zigzag sewing machine do not differ as much as dealers’ list prices for a particular Japanese-made zigzag sewing machine. Generally, a customer can bargain a greater amount off list price for Japanese-made machines than can be bargained off list price for European-made machines. List price includes those prices that a retailer might quote to a customer for the purpose of presenting some price and the actual selling price may be substantially reduced. The defendant Singer presently manufactures household straight stitch, replaceable cam and machine-carried multiple-cam zigzag stitch sewing machines in the States of New Jersey and South Carolina. Singer distributes them in the various states of the United States through its wholly-owned subsidiary, Singer Sewing Machine Company, which operates about 1600 retail stores throughout the United States. The principal portion of the Singer sales in the United States are through these retail stores. In addition, leased outlets are operated by Singer Sewing Machine Company in approximately 80 department stores located in various states. It also sells at wholesale to approximately 270 independent retail stores, which market all three types of zigzag machines. Singer also sells household sewing machines, including all three types of zigzag machines, in various foreign countries of the world through its own and independent distributors, who operate thousands of retail stores in such countries. Singer owns and operates plants manufacturing various types of machines in 14 foreign countries. Singer also offers financing for the purchases of its machines; provides servicing of the machines; and conducts sewing classes in their use. We noted also that Singer cuts its own logs for use in making its cabinets. In the years 1956, 1957, 1958 and 1959, 'Singer sold in the United States the number of units of the Singer 306 and 403 replaceable cam zigzag machines and of the Singer 319 and 401 multiple cam machines below set forth: Model No. 1956 1957 1958 1959 Foreign mfg.— 306 48,014 19,308 9,927 13,308 U. S. mfg.— 403 not in existence 50,269 319 56,965 31,838 4,199 1,028 401 74,503 147,446 155,422 We have observed (supra) that the manufacture by Singer in the United States of the Singer 319 machine was commenced, and of the 306 machine was stopped, in 1956. Of the Class 306 machines above set forth the following number thereof had been manufactured in the Singer Clydebank, Scotland plant (where they continue to be manufactured): 1956, 20,707; 1957, 17,708; 1958, 9,927 (all); 1959, 13,308 (all). All other machines above set forth, except 138 of the Class 319 machines, had been manufactured in the United States. In the years 1958 and 1959 Singer’s dollar volume of sales of the 401 machine amounted to $44,233,800 and $46,626,600 respectively, approximately 45% of its total gross dollar sales of all models of household sewing machines in the United States for each year. Singer’s Class 401 multicam zigzag sewing machine, with carrying case, sells at retail in the United States at $340. Singer’s Class 306 and 403 replaceable cam zigzag sewing machines, with carrying cases, sell at retail in the United States at $202 and $280, respectively. Singer’s Class 206 manual zigzag sewing machine, with carrying case, sale of which terminated in 1958, sold at retail in the United States in 1958 at $202. With the Singer machines, there is no bargaining about price in an outright sale. The Singer 401 was introduced to the market in 1957 over 1% years before the 403; it was supported with a vigorous and expensive advertising campaign: Singer spent in advertising the 401 machine approximately $2,145,000.00 in 1957; $1,270,000.00 in 1958; $1,340,-000.00 in 1959; and $1,399,000.00 in 1960. It was vigorously pushed by salesmen, being the top-of-the-line or most expensive sewing machine, and the salesman’s commission was computed on the basis of the sale price of the sewing machine. The Singer 403 machine was put on the market in April 1959 and Singer spent in advertising this sewing machine approximately $545,000.00 in 1959 and $120,000.00 in 1960. The Singer 404 machine was put on the market in January 1959 and Singer spent in advertising this sewing machine approximately $585,000.00 in 1959 and $130,000.00 in 1960. Notwithstanding the greater effort and expense in promoting and advertising the Singer 401 and its earlier appearance on the market, the sales of both the 403 and 404 machines have had substantial increases, whereas the sales of the 401 have shown little change. In its advertising, Singer presented its 401, 403 and 404 machines as being a group of three sister sewing machines, all of which would perform substantially the same function. It is against this background that we turn to examine the various agreements which, according to the Government, evidence the conspiracy to exclude competition in automatic zigzag sewing machines of foreign origin, in particular, of Japanese origin. F. The alleged conspiracy to restrain and monopolize trade. 1. THE AGREEMENTS CHALLENGED. a. Singer Vigorelli cross license agreement. During the period of the development of the Class 306, 319 and 401 machines, respectively, Singer commenced investigations to determine if Singer were free, from a patent standpoint, to manufacture and market these machines in the various countries of the world. This investigation to insure patent validity and freedom of infringement was continued from time to time during the tooling period of these three machines. In the course of its investigation, Singer in September 1953 came across the Vigorelli multicam zigzag sewing machine (Model-Zigzag ‘A’) and sought from its experts an analysis of the machine and advice on the claims it encompassed and employed. Its patent counsel advised Singer that, although it felt as a case of “last resort”, it could “cast doubt” on the validity of any claims Vigorelli might obtain, it could not say with certainty that it could overcome them. These claims, as we have seen, encompassed a “rotary pattern cam mechanism” with a removable nest of cams out of which a single cam could be selected and manually controlled, which was basically a modified form of the mechanism employed by Singer in its “306” machine disclosed in Singer’s expired United States Tiesler Patent (ideas also incorporated in Singer’s “319” and “401”). Vigorelli had not obtained a patent in the United States for its machine. Although Singer felt that the manually controllable means infringed two Singer-owned foreign patents, it was quite sure that the rotary pattern mechanism of Singer’s “306” infringed that of the Vigorelli Zigzag A. That mechanism had been completely disclosed in an instruction book put out by Vigorelli as early as August 1953; although Singer had found no Vigorelli patents claiming the rotary cam mechanism, it had little doubt that Vigorelli had applied for such a patent in Italy and possibly in the United States. While this possibility was considered by Singer as “the usual business risk”, Singer was far from certain that it could overcome Vigorelli’s claim but thought that it might be in a position to properly question its validity and, if required, to obtain a reasonable agreement. Singer had spent considerable time and money on its machines; the “306” and the “401” were in the process of being developed; nothing could be definitely determined regarding the Vigorelli machine while the patent applications, if any, were not open to inspection. Singer decided to take the risk of marketing its “306” machine while continuing its search for information as to the Vigorelli machine. In 1954, the first Japanese-made multicam machine was introduced by Brother International Corp. It incorporated the mechanism of the Vigorelli Zigzag A and the “401” machines. In April 1955, Singer first learned that Vigorelli had introduced a modified form machine which differed from the earlier Zigzag A in that the rotary cam mechanism through a cam follower could now select a pair of cams instead of just one. Singer also learned that the claims of both the Vigorelli Zigzag A and the modified form machines had been revealed in two unexpired Vigorelli Italian-issued patents, No. 497,557 (filed January 28, 1953) covering the first multicam machine and No. 507,862 (filed September 29, 1953) covering the modified multicam machine. However, the modified machine still retained the manually controllable means which infringed Singer’s foreign patents. More important, however, was the fact that Singer was of the opinion that the Vigorelli modified machine also infringed the Singer “401” machine covered by the Singer owned Johnson patent which had been filed on November 29, 1954. Although this filing date was after the filing of the Vigorelli Italian patents, the Singer “401” machine had been developed prior to the filing date of the second Vigorelli Italian patent. It was on this basis that Singer felt its patent application was dominant to that of Vigorelli’s. This confidence on Singer’s part was not to last long, however, for further examination of the earlier Vigorelli Italian patent led Singer to conclude that, if Vigorelli succeeded in obtaining a patent on the stack of cams with a single follower, it could dominate the basic idea of both the Singer “319” and “401” in foreign countries, and that it was more than likely that someone other than Vigorelli might dominate in the United States. In order to secure as much protection as possible, Singer then purchased the Harris patent No. 2,693,778 filed in the United States on June 9, 1952 and issued to Carl Harris November 9, 1954. Although this did not claim a multicam mechanism and therefore did not dominate any of the Singer zigzag machines, it did disclose, prior to any known use or known patent priority date, a plurality of rotary cams and a single cam follower, for selecting and relating the needle to a particular cam. Having acquired the Harris patent, Singer could endeavor to secure a claim broad enough to protect its “319” and “401” machines by obtaining a reissue of the Harris patent which would combine the Harris claim (which was disclosed but not claimed in the patent as issued) with those incorporated in the “401”, “319”, and the Vigorelli and Brother machines; by filing for a reissue, it could precipitate a patent interference proceeding between a Harris reissue application and any other pending application. A possible result of this course might be that the claims involved in the interference would be awarded to the Harris patent by reason of its prior filing date. Another possible result might be that the Patent Office would reject the claims as too broad. It was the view of Singer that such a rejection would serve as a good indication that no one else could be awarded the claims. It was with this purpose in mind and to protect its “319” and “401” machines that Singer acquired the Harris patent. However, Singer was confronted with still another problem: whether Singer’s broadened claims, if allowed on a reissue application of the original Harris patent, would relate back to the early filing date of June 9, 1952 which would give Singer six months priority over Vigorelli’s Italian patent, on the multicam and selector means, the particular mechanism common to the Singer “319” and “401” machines; and whether, in the happening of such event, this earlier priority date would be given under the law of Italy to the Italian Harris patent which had been filed six months after the Vigorelli Italian patent. If the earlier date of June 9, 1952 were accepted in Italy it would give Singer priority in Italy as well as in the United States. On the other hand it was entirely possible that neither eventuality would occur, and that Singer would not have priority anywhere. But, whatever the result might be, Singer felt that with the Harris patent, it was in a better position to bargain; and even though, Singer was anxious to adjust the matter by agreement with Vigorelli, Singer proceeded with great •caution. Singer did not think it wise to reveal to Vigorelli at that time what its purpose or views were. Litigation developed as anticipated but from an unexpected quarter — Brazil. Here, Vigorelli had filed a patent application, which under Brazilian law Singer felt compelled to oppose lest Vigorelli achieve what might eventuate into a •dominant position. Accordingly, Singer filed opposition to the Vigorelli application in Brazil. Such a step, it knew, would be only the beginning for it foresaw, and rightly so, that to stop Vigorelli from obtaining dominant patent rights it would have to oppose in each country in which Vigorelli might choose to file. Right on the heels of the Vigorelli-Brazil opposition, Singer found itself faced with another application in Brazil by Brutsch & Co. on a multicam arrangement. Singer also felt compelled to oppose this Brutsch application; and also a further application by Vigorelli filed in Great Britain. It was soon quite obvious that the race for a patent on the multicam mechanism promised to become bitterly contested— indeed, a desperate one with the victor unknown. And yet, in spite of the urgency of the situation, Singer adopted a strategy to have its planned encounter with Vigorelli appear “fortuitous” and to proceed with the “greatest caution” in making the first move, especially since it felt that Vigorelli- — as a competitor — ■ might not feel either too sure or too confident of its position. Singer decided to test and explore Vigorelli’s reaction to some agreement and, if it was friendly, to hold a further meeting. Although it was planned by Singer that its New York patent counsel Stanford would go to Italy expressly for any arrangement that might be worked out, Singer went to great pains not to give the impression that anybody from its organization would make a special trip, preferring to have it appear that someone from Singer, while in Europe on other business, could handle the arrangements with Vigorelli. Stanford was to tell Vigorelli that Singer knew that at least two other companies were planning to acquire patents which might adversely affect it and Vigorelli and that standing together both could more effectively dissipate the effectiveness of such an acquisition. He was to convey the thought that Singer could assist Vigorelli. There followed a discussion between Vigorelli and Singer’s Italian representative, Lando, from which it was clear that Vigorelli had a “shrewd idea” of Singer’s plan and was “purposely or otherwise” vague about the Brazilian patent — and pretended ignorance of Singer’s opposition there. During the negotiations, Singer for the first time heard from Vigorelli of a Gegauf patent covering a multicam mechanism which, according to Vigorelli, had been deposited by Gegauf in a small number of countries and that Vigorelli was negotiating with respect to it. Singer’s endless quest for patents on the multieam mechanism had failed to uncover any such patent but Singer was careful to hide this fact from Vigorelli. Singer proceeded then to attempt to learn from Vigorelli “unobtrusively and without any degree of emphasis” the basis of the discussions between Gegauf and Vigorelli. The fears aroused in Singer for the future of its “401” and “319” machines by the discovery of the earlier Vigorelli patent were now further sharpened by the discovery of the even earlier patent, which, according to Vigorelli, had also been deposited in the United States. It was imperative that Singer come to some immediate agreement with Vigorelli, for the alternative of pressing the Harris reissue in an attempt to frighten off Vigorelli and others had lost its value, since Singer feared that, if it did push this application, it would be revealing to Vigorelli and Gegauf the weakness of its position. To make matters worse, it was informed by its British patent counsel that its opposition to the British Vigorelli application would have failed. At this point, Vigorelli had also filed a United States application corresponding to its two earlier Italian patents. Thus concludes the background against which the license agreement was entered into by Singer with Vigorelli on November 17, 1955. It can hardly be seriously contended that the agreement was a preliminary step to effectuate a conspiratorial plan or an attempt to monopolize. In truth, Singer’s back was against the wall in this matter and it was only thru swift and clever tactics that it was able to wrest some sort of victory out of what promised to be total defeat or at best a Pyrrhic victory. It is most significant that throughout its negotiations with Vigorelli and right through the execution of the license agreement, Singer had no independent knowledge or information with respect to the Gegauf I patent. Singer had absolutely no contacts or dealings with Gegauf, whom it did not even know. Had it not been for Vigorelli’s volunteering the very scanty information on the Gegauf I patent, Singer would have remained in total ignorance of it for prior to and even after learning of it, Singer had been unable to discover any trace of such a patent even though its search had been continuous and thorough. As late as November 14, 1955, Singer’s German patent counsel was still searching for German and Italian applications with no success; it was not until January 1956, after its license with Vigorelli had been finally executed, that it discovered Gegauf’s United States application. It was much later that Singer met Gegauf. The fact that Singer knew that Vigorelli was negotiating with Gegauf about, the patent did not charge Singer with knowledge of any possible wrongful purpose of these negotiations, or with the parties’ intent (be it good or bad), nor did it impose on Singer a duty to make further inquiry. There is no evidence to' support an inference that Gegauf knew of the negotiations .between Singer and Vigorelli. At no time during the negotiations with Vigorelli was any mention made of excluding Japanese competition. There is no evidence that ‘ Singer was. then contemplating, or that it had mentioned, that it planned to purchase any patent from Vigorelli, Gegauf or Messerschmitt. The license agreement of November 17, 1955, which Singer made with Vigorelli provided (1) that Singer would not bring any infringement action against Vigorelli under the patents issued or about to be issued in any country with respect to the subject matter disclosed in Vigorelli’s Italian patents 497,557 and 507,862— when embodied in sewing machines manufactured and sold by Vigorelli; and (2) that Vigorelli wiould not bring any infringement action against Singer under patents issued or about to be issued in any country with respect to the subject matter disclosed in United States patents No. 2,693,778 and in United States applications by Johnson No. 471,766 and by Perla No. 386,684 when embodied in sewing machines manufactured and sold by Singer; and (3) that neither would institute any opposition, nullity or invalidation against or otherwise attack any of the above noted patents or applications and Would withdraw any such proceeding if already instituted; but that in the event the parties did become involved in any office priority proceedings such as a “United States interference” or a “Canadian conflict proceeding”, both would work to settle such proceedings in accordance with the laws and regulations of the patent office concerned. The agreement was limited expressly to the patents which threatened to involve the parties in litigation over priority— the two Vigorelli Italian patents Nos. 497,557 and 507,862 and only “when embodied in sewing machines manufactured and sold by Vigorelli”; and the United States Singer patent No. 2,693,778, Johnson No. 471,766 and Perla No. 386,684, and again only when “embodied in sewing machines manufactured and sold by Singer”. The proviso not to sue each ■other for infringement and not to oppose each other’s claims on these patents was perfectly consistent, proper and lawful with the exchange of licenses under their respective patents and, if the lack of opposition did result in permitting the issuance of broad claims to each one under his patents — -it was not unlawful for it was being done for a lawful purpose. There is no duty, for public benefit or otherwise placed on a patentee or licensee to oppose the claims of another in order to narrow or invalidate the scope of patent which might issue to the other. The provision to withdraw any interference proceedings which might have been instituted prior to the agreement and to settle interferences in accordance with the laws and regulations of the patent office involved “and in the spirit of the agreement” were steps — and lawful ones ■ — necessary to effectuate the mutual promises and to carry out the obligation not to become involved in litigation with each other. Neither licensee was nor could be sure enough of his ground to risk patent litigation. Each party in licensing the other, surrendered a valuable property right in exchange for permission to use the other’s property. We find that there was no agreement to use the legitimate means of a license to stifle competition by helping each other acquire broad patent claims and by agreeing to assert the patents only against certain competitors. We find that there was no agreement or understanding between Singer and Vigorelli that was not there expressly stated. There was no promise or commitment made by either of the parties with respect to licensing or not licensing, enforcing or not enforcing, by infringement action or otherwise, of any patent, then owned or subsequently to be acquired, or with respect to the use in any way of any such patent, alone or in conjunction with any other patent; and no agreement that either would restrict in any way its ownership of any patent. We find that in approaching and in bargaining with Vigorelli, Singer was at all times dealing at arm’s length, solely in its own interest for the purpose and with the intent of reaching a cross-licensing agreement. Singer’s purpose in entering into the cross-licensing agreement with Vigorelli was to secure to Singer the ability to sell its “401” and “319” machines in the various foreign countries where sale might otherwise have been foreclosed by enforcement of the Vigorelli patents, or at least to be free from the threat of litigation with respect to these patents. 6. Singer Gegauf license agreement. We have seen that during its negotiations with Vigorelli, Singer for the first time learned about the Gegauf patent and Vigorelli’s negotiations with Gegauf. On October 20, 1955, Singer discovered that the Gegauf patent had been deposited in Switzerland on May 31, 1952, and at the same time obtained a copy of its corresponding Italian patent which enjoyed the same date. This patent disclosed (1) an embodiment of a zigzag stitch machine, having a stack of cams and a single cam follower, which by sliding lengthwise of the axis of the cams could engage any one of such cams, and (2) an embodiment of a zigzag stitch machine having a stack of cams with each cam having its own individual follower. In January 1956, in its continued and extended search, Singer learned that on May 20,1953, Gegauf had filed a United States application corresponding to the Swiss application and bearing the date May 31,1952. This was nine days earlier than the priority date of Singer’s United States Harris patent No. 2,693,778 which had been filed on June 9, 1952. At this time Singer also learned that Vigorelli had entered into a license agreement with Gegauf similar to that which it had with Singer. In January 1956, Singer was advised that its Harris reissue patent was about to issue. Singer feared that an interference might be declared between this patent and the United States application of Gegauf. Singer was therefore most anxious to negotiate an agreement with Gegauf similar to the one it had with Vigorelli. Armed with the knowledge that the Gegauf patent had priority of nine days (which it assumed Gegauf did not know), Singer felt that it was in a better bargaining position and thus Singer was anxious to conclude an agreement before the interference disclosed to Gegauf its superior position. Singer did not inform Vigorelli of its plan however but did suggest to its Italian representative that, without arousing Vigorelli’s curiosity, he find out the details of the Vigorelli-Gegauf agreement and the names of the Gegauf officials with whom Vigorelli negotiated or their patent attorneys as well as the location of their offices. Singer was particularly anxious to know what Vigorelli had found out with respect to Gegauf’s patents which had induced Gegauf to drop its original demand of $160,000 and grant Vigorelli a license for nothing. It is clear that Singer intended to negotiate with Gegauf separately and as secretly as possible. Although it made use of Vigorelli, it did so as a matter of necessity and solely to gain bargaining information. Vigorelli, on its part, apparently was just as secretive about its affairs. Singer’s representative, Dr. Lando, met with Vigorelli on February 29, 1956. As a result of this meeting, Lando was able to report that Vigorelli had stated that it had obtained a free license from Gegauf because of the comparative weakness of Gegauf’s Italian patent, and because of the fact that Gegauf had deposited its patent in only four countries as opposed to filings in seventeen countries by Vigorelli, and because of Vigorelli’s awareness of certain patents which Gegauf considered dangerous to its patent. Lando also reported that Vigorelli’s curiosity as to Singer’s motive had been aroused, but he added that Vigorelli thought Singer was collecting information to oppose the Gegauf patent in the United States in order to prevent the sale of its machine there. Lando further reported that his (Lando’s) expression of doubt as to this disappointed Vigorelli since Vigorelli was apparently hoping that Singer was about to get active against Gegauf in patent contests in the United States, all to its (Vigorelli’s) benefit. Gegauf and Vigorelli were not exchanging confidences nor were they seeking to promote each other’s interests. The treatment accorded Gegauf by Singer was to be no more candid — Singer’s objective being to keep Gegauf in the dark as long as possible and to disclose only what was absolutely necessary to the effectuation of Singer’s plans. Singer had decided to approach Gegauf in substantially the same manner it had approached Vigorelli, that is, with intimations of litigation. The Singer Swiss Manager informed Gegauf that Singer was desirous of discussing “patent questions”. On April 13, 1956, a momentous meeting was held at the Gegauf factory in Steckborn, Switzerland. When entering negotiations at this conference, Singer knew that Gegauf had a patent issued in Switzerland with a priority date nine days before that of the Harris patent and that the principal claim of this patent read directly on the Singer “401” machine. Singer also knew that Gegauf had filed a United States application, claims of which Singer presumed would read on the “319” and “401” machines. Singer was also advised of the fact that Gegauf had an application pending in Germany, which might mature into a patent which would read upon the “319” and “401” machines, and that Gegauf also had an Italian patent the validity of which might be put in question due to the manner in which it was written. Singer also had information that Gegauf was reported to have serious worries as to whether certain prior patents, if called to the attention of Patent Offices, would limit or invalidate its claim. Singer realized too that the Harris reissue application in the United States read on the Gegauf machine and that the various Harris patent applications on file in foreign countries, had claims which if they could be properly amended would read on the Gegauf machine. Waterman of the Singer United States office reported on this 7% hour meeting to New York as one which was not as straightforward as that with Vigorelli, due to a feeling on the part of Gegauf that its situation was superior and that it was “suspicious of our intentions”; that Singer did nothing to dispel Gegauf’s fear that it was going to be hurt in the United States by the lower priced Japanese machines, because “one of the strong points” which was to be used in favor of the agreement was protection against the Japanese. Waterman also reported that Gegauf had thrown out a lot of topics having nothing to do with patents, among them a suggestion that there be a division of territories between Gegauf and Singer which “was brushed aside pronto in short order”. Waterman also felt that Gegauf was very much afraid that Singer wanted to copy its machine and wanted a promise to the effect that it would not do so; and he left Gegauf with no doubt that Singer was going to oppose the issuance of its patent — in all four countries and that it could knock out its claim but that both could be hurt. So suspicious was Gegauf of Singer’s motives that it dre
