383 F.2d 455 | 3rd Cir. | 1967
The appeal and cross appeal at bar concern patent rights and trade secrets respecting a “Snap Action Device” among whose uses are a switch for an automobile directional signal flasher, a thermostat, a circuit breaker and an overload protector. In the suit at bar, however, we are concerned only with the device’s use as a switch for an automobile directional signal flasher. We shall discuss it primarily in this connection. The device is disclosed by Reissue Patent 24,023.
I. The Issue op Validity op Reissue Patent 24023.
In 1952, Schmidinger, the individual plaintiff, was issued United States Reissue Patent 24,023 for the “Snap Action
Schmidinger and Tung-Sol assert that the Welflash flasher constitutes an infringement of claims of the 023 patent and that the defendants are guilty of unfair competition in that Welsh misappropriated the plaintiffs’ trade secrets for the mass production of flashers. The defendants assert that the 023 patent is invalid, deny infringement and unfair competition. Jurisdiction is based on Section 1338 and 1400(b), 28 U.S.C.
The court below held five claims (hereinafter set out) of the 023 patent valid and infringed by the Welflash device but that there had been no misappropriation of trade secrets. See 243 F.Supp. 852.
Schmidinger and Tung-Sol have appealed at our No. 15830 from the ruling of the court below that there was no misappropriation of trade secrets. The defendants have appealed at our No. 15831. from the holding that the 023 patent is valid and infringed by the Welflash device.
The patent specification describes a snap action device that may be actuated by electrical, thermal, or mechanical forces, or by a combination of them. The device comprises three elements; (1) a disc, (2) a laterally flexible pull wire or strip secured at its ends to the disc at the opposite ends of a diameter, and (3) a support element secured to the pull strip, preferably at the center of said pull strip. The disc is of spring material and has a crease along its diameter underlying the laterally flexible pull strip. The pull strip may be continuous between the points of its attachment to the disc and is mounted on a support under longitudinal tension. The support is to be so constructed as to permit adjustment or variation of the tension in the strip. The specification goes on to state that the disc under predetermined increase of tension in the pull strip snaps from a position in which the halves of the disc on each side of the crease extend outwardly away from the pull strip at an angle of less than 180° to a second position in which the disc is bowed in the opposite direction about a diameter of 90° to the preformed crease.
As to the operation of the device, the court below stated, id. supra, at 855:
“In operation, and in the initial starting position, tension in the pull ribbon holds the buckling member in its snapped position. In this position the center of the buckling member is bowed out to form a channel positioned 90° to the permanent deformation and*458 of opposite curvature thereto. The 90° channel of opposite curvature causes a gap to form between the buckling member and the pull ribbon. This 90° channel of opposite curvature is characteristic of the snap action of what plaintiffs termed the ‘hard’ buckler of the patented device, which Schmidinger achieved by means of a single flexible pull ribbon arranged on the convex side of the buckling member parallel to the deformation.
“When the buckling member is in its snapped position, a gap is formed between the buckling member and pull ribbon. At such time the electrical contacts are closed. When the operator of the automobile moves the signal lever into signalling position, electric current passes through the buckling member and pull ribbon in a divided flow to generate heat and relax the tension in the ribbon. As a result, the buckling member snaps to close the gap and open the electrical contacts. Thereupon, the buckling member and pull ribbon cool and contract, until the tension in the ribbon is restored to snap the buckling member and open the gap. The electrical contacts again close, and the cycle is automatically repeated as long as the directional signal lever remains in signaling position.
“In each of the two positions assumed by the buckling member in its back- and-forth snap action, there is a so-called ‘locking’ effect, where the buckling member dwells in position. This dwelling in each position is due to the differential expansion and contraction of the pull ribbon and buckling member. The buckling member remains or dwells in each position while the pull ribbon is expanding or contracting, but thereafter suddenly snaps and moves very rapidly through an equilibrium position located between the two ‘locked’ positions. The differential expansion and contraction are caused by the divided ciicuit flow of current through the buckling member and pull ribbon, and the ambient cooling thereof.” '
In an attempt to describe the operation of the 023 device as a directional signal flasher in simplest terms, we state that an electric current flows through the flexible pull ribbon to the disc. The pull ribbon when heated by the current, expands and thereby allows the disc to snap to its natural shape which breaks the flow of electricity through the disc to the flasher light. As the metals of the pull ribbon and the disc cool the disc returns to its original creased condition causing the flasher light to go on again and the cycle is repeated.
The claims in issue are set out in the footnote.
The plaintiffs seemingly concede and we conclude, as did the court below, that the three elements of the specification as hereinbefore stated were fully anticipated by the prior art but they contend that the combination of those three elements creates a device that is new, useful and nonobvious, and therefore patentable. We agree for the reasons stated hereinafter.
We desire to make it clear that we are aware that the validity of claims of a combination patent cannot rest on any “essential” element “gist” or “heart” asserted to lie in the invention. Aro Manufacturing Company v. Convertible Top Replacement Company, 365 U.S. 336, 345, 81 S.Ct. 599, 5 L.Ed.2d 592 (1961).
If we turn to Claim 12 of the patent which we deem to be substantially similar to the other claims in issue save Claim 26, we find that it claims a snap-action device “according to claim 10”; the tension pull ribbon and the disc to be varied by the differential expansion and contraction of the pull ribbon and the disc by passing an electric current through them.
The issue presented, therefore, is whether 023 meets the test of Section 103 of the Patent Act of 1952, 35 U.S.C. The standard was declared by the Supreme Court by Mr. Justice Clark in Graham v. John Deere Co., 383 U.S. 1, 86 S.Ct. 684, 15 L.Ed.2d 545 (1966).
“The questions, involved in each of the companion cases before us, are what effect the 1952 Act had upon traditional statutory and judicial tests of patentability and what definitive tests are now required. We have concluded that the 1952 Act was intended to codify judicial precedents embracing the principle long ago announced by this Court in Hotchkiss v. Greenwood, 11 How. 248, 13 L.Ed. 683 (1851), and that, while the clear language of § 103 places emphasis on an inquiry into obviousness, the general level of innovation necessary to sustain patentability remains the same.” Mr. Justice Clark went on to make clear that the factors by which non-obviousness are to be tested are substantially the same as were those of the decisional law as it existed prior to the time of the 1952
Schmidinger at the trial described how he developed his 023 snap-action flasher. Until 1954 motor vehicle flashers had operated by magnetism. Tung-Sol had manufactured a magnetic flasher devised by Schmidinger which had wide use in the motor vehicle field. Schmidinger had secured a patent No. 2,177,671 for a "Thermal Switch and the Like”, issued on October 31, 1939 on an application filed on April 30, 1937. He also had received a patent No. 2,299,767 for a "Thermally Operated Switch and the Like”, issued on October 27, 1942 on an application filed on February 2, 1940. The teachings of the 671 and 767 patents are prior art in this case. Schmidinger testified that in 1943, attempting to improve his non-magnetic flasher, he directed his attention to the device shown in Fig. 11 of 671. He removed the glass bead at the end of the left arm at numeral 52. He then changed the position of the pull wire to the proximity of the vane, at numeral 12. The design thus created was somewhat similar to that shown at Fig. 25 of 767.
Schmidinger then applied the electric current to the center of the pull wire. There was nothing new about this as is shown by the Hanson (Netherlands) Patent No. 6,711 published March 15, 1922 for an “Automatic Circuit Breaker.” Schmidinger next bent his buckling member in the center at right angles to the pull ribbon as shown by Fig. 8 of the Klahn Patent No. 1,784,450, issued on December 8, 1930 on an application filed February 25, 1926. Klahn’s Fig. 8 discloses such a deformation but what it fails to show is a deformation along the long axis. The defendants insist that a diametrically deformed disc-shaped buckling member created by creasing it through the diameter would be obvious to a man having ordinary skill in the art. But with this we cannot agree. Schmidinger next employed a pull ribbon in lieu of a pull wire. There can be nothing non-obvious in exchanging a pull ribbon for a pull wire but the pull means is described in 023 as both “laterally flexible” and “expansible”. Moreover, as disclosed by 023 the pull strip is attached to the disc in such a manner as to bow the disc in the opposite direction about a diameter of 90° to the preformed crease. Schmidinger then experimented with disc-shaped buckling members, as disclosed in the Spencer Patent No. 1,883,252 issued on October 18, 1932 on an application filed August 15, 1931.
It appears that there was a period of experimentation by Schmidinger as to the size and operation of the members of the device evolved by the disclosures of the patent in suit. This period of experimentation was not as extensive as the plaintiffs contend. The court below laid emphasis upon the fact that Schmidinger had begun his work on automobile signals installations in 1931 and progressed through electromagnetic flashers to mechanical ones. But it is necessary to point out that Schmidinger’s experiments on mechanical flashers, resulting in the device of 023, were not prolonged and were brought to fruition in not more than two years. The period required by Schmidinger to perfect his device is not too helpful to him here.
The court below stated, 243 F.Supp. at 860: "The interrelationship of the parts, as put together by Schmidinger, and their functioning dependency on each other, has produced a unit capable of performing the reciprocating snap action with its ‘locking’ effect, and of generating the heavy snap forces required for opening and closing the electrical contacts with firm contact pressure, fast
This statement is undoubtedly supported by the record, but we point out that the court below employed functional terms in describing the operation of the 023 device and that patent claims at least under the circumstances at bar cannot be sustained by functional conclusions. We do not undervalue Sehmidinger’s experiments; nor do we conclude that he was merely routineering. We note again that the last sentence of Section 103 states: “Patentability shall not be negatived by the manner in which the invention was made.” An invention made even accidentally is patentable,
We have given consideration to the substantial commercial success of Schmidinger’s flasher, well founded in the record, commencing with the sale of the 023 device in 1956 to the Pontiac division of General Motors. The record shows that by 1963 approximately 99% of the flashers employed in the automotive industry were Schmidinger’s. While a portion of these large sales may well have been brought about by the decreased electric current presently employed to operate flashers,
Considering the prior art and weighing the whole record on this phase of the case, we conclude that Schmidinger’s disclosures were not “obvious * * * to a person having ordinary skill in the art.” 35 U.S.C. § 103. We therefore hold all claims in issue valid,
As to Claim 26, no support is claimed. The court below stated, id. supra, 243 F.Supp. at 860, “However, while a support may be necessary for an operable structure, it is not a basic element of the invention, and need not, therefore, be set forth in the claim. It is quite apparent that one skilled in the art would know how to support the device of claim 26 in order to make it operable.” This is not enough and the court below was in error in so concluding. A support is necessary to make Schmidinger’s device operable and in a combination patent there is no single essential element. Every element in the combination must join in setting out and defining an operable device possessing utility. Aro Manufacturing Company v. Convertible Top Company, supra, 365 U.S. at 344-345, 81 S.Ct. at 603-604. We hold Claim 26 to be invalid.
II. The Issue of Infringement
The defendants contend that during the prosecution of 023 in the Patent Office the patentee agreed to certain limitations of his asserted claims. Having agreed to these limitations in order to obtain allowance of 023, the defendants contend that Schmidinger cannot now claim that which he previously had released to the public domain. Specifically, the defendants argue that Schmidinger, in order to overcome Patent Office objections based on prior art, limited
An understanding of the current scope of Reissue Patent 24,023 requires an analysis of proceedings before the Patent Office started on July 6, 1944. On that date, Schmidinger filed application No. 543,623 for a “Thermal Control Means”. During the prosecution of that application, the Patent Office rejected Claims 1, 18, 19, and 20 on prior art claiming Schmidinger’s device disclosed no new invention over Schmidinger 767 and 309 and Newton 2,267,164. Schmidinger responded by amending Claims 1, 18, 19, and 20, noting in his “Remarks” that such amendments were directed specifically to attaching the support solely to the pull means in order to overcome the prior art. A reading of the amended claims does indeed disclose that the support is connected only to the pull means. By his oath Schmidinger repeated the importance of this arrangement and argued that it overcame successfully the prior art. Subsequently, Schmidinger added Claims 41-44 to application 623. These new claims described the buckling member as being supported solely by the pull means. 623 was later abandoned in favor of application No. 237,958, filed July 21, 1951, which resulted in Patent No. 2,615,106 issued on October 21, 1952, which in turn was the basis for the Reissue Patent in suit. In the prosecution of 958 Schmidinger continued Claim 41 of 623 as new Claim 10. Claim 41, as noted, provided that the buckling member be supported solely by the pull means. After 958 had been allowed and Schmidinger had experimented with a device which had the support attached to the buckling member, on advice of counsel, he requested a reissue patent which would include claims for a support attached to the buckling member. In a supplemental oath to the reissue application he swore: “[T]he claims of said patent are inoperative to protect adequately [the] invention in that they are limited to attachment of a support to the pull means * * In order to achieve a broadening, Schmidinger included Claim 25 in his reissue application, a claim which could be read to include a support on either the buckling member or the pull means. The-Patent Office rejected Claim 25 on Norwegian Patent 957, and subsequently rejected as new matter the language in the specifications which implied that the support could be attached to the buckling member. The Patent Office demanded deletion of all like language and stated in a letter of September 8, 1954: “The support was not originally disclosed as being connected directly to the disc and to refer to such a construction * * * is to disclose new matter * * * Claims 25-27 are rejected as containing new material * * *.” Schmidinger complied by deleting all of the alleged offensive language. Moreover, Schmidinger had previously amended Claim 25 to remove any implication that the support could be attached to the buckling member. Thus, Schmidinger did not succeed in broadening his claims to include a device in which the support was attached directly to the buckling member. He cannot now claim that such a device infringes his patent. * * *
As noted, the defendants also contend that Schmidinger limited his device to a disc-shaped buckling member. The definition of the word “disk” or “disc” is given in Webster's New International Dictionary of the English language, 2 ed., as “A flat circular plate; as, a disk of metal * * The definition is one of common usages and we accept it.
In the original application 623 and its accompanying figures Schmidinger claimed buckling members of varying shapes. The Patent Office responded in a letter of October 28, 1946, stating: “In view of the rejection, below, of the generic claims, election of a single species (i. e. a single form of support and a single form of buckling member) is required * * This demand was
The alleged infringing devices variously have rectangular buckling members, not discs and their pull means are not fastened to the support.
The court below despite the fact that it found that there was no literal infringement of 023 nonetheless disregarded the particular structure and the elements of the claims, broadly employing
Here, Schmidinger abandoned too much and now faces the limitations imposed on his claims by those abandonments. He cannot be permitted to recover what he lost in the Patent Office proceedings. We hold that there was no infringement.
III. Unfair Competition.
The issues presented under this heading will be discussed briefly. The court below was requested not to disclose any of the details concerning the plaintiffs’ asserted trade secrets in its opinion. We need not refer specifically to facts for it is clear from the record that the court below had substantial bases for its findings. The court stated, 243 F.Supp. at 865, as follows: “A careful consideration of that part of the record relating to plaintiffs’ cause of action for unfair competition leads the Court to conclude, in light of applicable law, that plaintiffs have not sustained their burden of proving by a preponderance of the evidence that what they claim as confidential information and trade secrets are in fact such, or, if they could be so classified, that defendants have utilized such data in their mass production of the infringing device.”
In respect to the trial judge’s concept of the law of trade secrets he stated that Schmidinger’s work in measuring the snap and unsnap forces of his buckling member “involved no more than the application of ordinary engineering skill to obtain uniformity of these forces.”
There can be no point in remanding the case so that the trial judge may simply rephrase his conclusions of law. His decree was correct. Accordingly, we will affirm the decision of the court below on the issue of unfair competition.
The judgment of the court below on the issue of validity of the claims, save only Claim 26, will be affirmed. The judgment of the court below on the issue of infringement, as indicated, will be reversed.
. Reissue Patent 24,023 was reissued June 14, 1955 upon an application dated May 3, 1954, Serial No. 427406. The original Patent 2,615,106 was dated October 21, 1952, Serial No. 237958, July 21, 1951.
. The defendant, Oxford Electric Corporation and its wholly-owned subsidiaries, defendants Hudson Lamp Company, Inc. and Best Manufacturing Company, Inc., have acquired all the physical assets, manufaeuring techniques, and knowledge of Welflash, Inc., to carry on the business of that company in the production of the accused device which is a directional signal flasher. Oxford, Hudson and Best manufacture the Welflash flasher, the alleged infringing device.
. Second and third counterclaims, charging unfair competition and violation of antitrust laws, referred to in tha opinion 243 F.Supp. at 854 as being reserved, were dismissed with prejudice by a stipulation approved by Judge Augelli on November 15, 1965. The judgment appealed from is final.
. Charles Becker, Manager of the Sales Department of Tung-Sol, describes the Schmidinger device, P-2, in lay terms as “This is the Tung-Sol series flasher that incorporates the buckling member with a hot wire attached to either end on the convex side, current flowing through the wire causes the buckler to snap, opening and closing contact, [and thereby] flashes the lamp.”
. “12. The snap action device according to claim 10 wherein said pull means and disc are of electrical conducting material and the tension in said pull means is varied by differential expansion and contraction of said pull means and disc with passage of current therethrough.” (Emphasis added.)
Claim 10, not in issue, is incorporated into claim 12. Claim 10 reads as follows:
“10. A snap action device comprising a disc having an inherent diametral deformation therein tending to cause it to assume a constrained shape, a support element having laterally flexible pull means fastened thereto and radiating out therefrom, the outer ends of said pull means being fastened to points of said disc at opposite ends of the deformation therein and on the convex side thereof whereby when the tension in said pull means is reduced the center of the disc snaps in one direction to assume its constrained shape and when the tension in said pull means increases the snap action of the*459 center of the disc occurs in the other direction.”
The other claims in issue follow:
“17. A thermal switch device comprising a support, a buckling member having a portion adapted to occupy two different positions for operating a circuit opening and closing contact, and linear expansible pull means carried by said support and fastened at two spaced points to said buckling member to control the buckling thereof to cause said portion to occupy one of said positions responsively to current flowing through the expansible means, and said buckling member being carried by said expansible pull means, the buckling member being the form of a constrained disc with the outer ends of the expansible means fastened to one side of the disc at diametrically opposite points adjacent its periphery.”
“18. A thermal switch device comprising a support, a buckling member having a portion adapted to occupy two different positions for operating a circuit opening and closing contact, and linear expansible pull means carried by said support and fastened at two spaced points to said buckling member to control the buckling thereof to cause said portion to occupy one of said positions responsively to current flowing through the expansible means, and said buckling member being carried by said expansible pull means, the buckling member being a disc of comparatively thin spring metal doubly constrained by having a transverse bend formed therein and by the pull of the expansible means fastened at its ends to the convex side of said bend.”
“23. A thermal switch device comprising a support, a substantially circular buckling member carrying a contact and having an inherent constraint tending to move said contact through a dead center position to occupy a circuit controlling position and linear expansible pull means carried by said support and fastened to said buckling member at two spaced points on the opposite sides of a transverse line passing through said contact to control the buckling thereof responsively to current flowing through the expansible means and said buckling member being carried by said expansible pull means.”
“26. In a current responsive snap action device, a disc-like member of resilient electrically conductive material having a preformed crease along one diameter only to provide a single stable conformation in which the portions of the disc-like member on each side of the diameter form an included angle of less than 180°, and a flexible ribbon of electrically conductive material fixed to the disc-like member only at opposite ends of said diameter and overlying said diameter on the convex side of the crease, said disc-like member, depending upon the tension in said ribbon being either in the said position of stable conformation or in a position wherein it is bent oppositely thereto and about a diameter of 90° to said preformed crease whereby differential expansion and contraction of said ribbon and disc-like member with passage of current there-through changes the tension in said ribbon and causes snap action of said disc-like member through a neutral planar position from one of the other of said first mentioned positions.”
. The Supreme Court decided three cases. See the star note cited to the text at 383 U.S. 1, 86 S.Ct. 684. The three cases are collectively called the “John Deere Cases.” See also United States v. Adams, 383 U.S. 39, 86 S.Ct. 708, 15 L. Ed.2d 572, decided the same day as the cases referred to, supra, in this note.
. Ҥ 103. Conditions for patentability; non-obvious subject matter
“A patent may not be obtained though the invention is not identically disclosed or described as set forth in section 102 of this title, if the differenees between the subject matter sought to be patented and the prior art are such that the subject matter as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains. Patentability shall not be negatived by the manner in which the invention was made.”
We need not discuss the provisions of §§ 101 and 102. In any event we hold that Schmidinger’s disclosures satisfy the requirements of the designated sections.
. See for example Electric Storage Battery Co. v. Shimadzu, 123 F.2d 890, 893 (3 Cir. 1941). Compare the history of the discovery of Charles Goodyear’s vulcanized- rubber: Goodyear v. Day, 10 Fed.Cas. p. 678, No. 5,569 (1852).
. See Schmidinger’s testimony pp. 767a-68a.
. In respect to the provisions of 35 U.S.C. § 282, the statutory statement creating presumptive validity, we agree with the court below that the burden of proving invalidity in the face of the presumption is a heavy one, but the presumption is by no means conclusive. See Mumm v. Jacob E. Decker & Sons, 301 U.S. 168, 57 S.Ct. 675, 81 L.Ed. 983 (1937). It is our conclusion that the presumption of validity conferred by the statute has not been overcome in respect to the 023 device.
. Claim 11 was also rejected as not readable on the elected embodiment, but for other reasons. See Patent Office letter dated January 11, 1949 referring to an earlier letter dated October 28, 1946.
. The alleged infringing devices are identified in a stipulation dated April 11, 1963 and approved by the court below in its Pre-Trial Order dated April 16, 1963, viz., the structures of the devices to Tag Nos. 1, 5, 6, 13A-13H, 13J, 13K, 19, 20 and 24. .See Paragraph 13 of the judgment of August 25, 1965.
. The court below in its opinion at 863 stated: “[A]t no time during the prosecution of the several applications in the patent office did Schmidinger insert the word ‘disc’ or the expression ‘support attached to pull ribbon’ into any of the claims in order to overcome or avoid a rejection on the prior art patents. Nor does it appear that Schmidinger abandoned all shapes for his buckling member, other than round, when he made an election of species of a disc. In fact, the patentee at all times asserted claims to a buckling member regardless of shape, or to a ‘disc-like’ buckling member which was the equivalent of the other shaped buckling members of the prior art patents.”
We cannot agree with the import of this statement. The file wrapper history of 023 will not permit the broad construction and the use of equivalents as claimed by Schmidinger. He obtained the issuance of 023 by distinguishing prior art and he cannot now validly obtain that which was previously by limitation excised from his applications and claims. This matter was well put in Exhibit Supply Company v. Ace Patents Corporation, 315 U.S. 126, 136, 62 S.Ct. 513, 518, 86 L.Ed. 736 (1942), in which the court said: “Assuming that the patentee would have been entitled to equivalents embracing the accused devices had he originally claimed a ‘conductor means embedded in the table’, a very different issue is presented when the applicant, in order to meet objections in the Patent Office, based on references to the prior art, adopted the phrase as a substitute for the broader one ‘carried by the table’. Had Claim 7 been allowed in its original form, it would have read upon all the accused devices, since in all the conductor means complementary to the coil spring are ‘carried by the table’. By striking that phrase from the claim and substituting for it ‘embedded in the table,’ the applicant restricted his claim to those combinations in which the conductor means, though carried on the table, is also embedded in it. By the amendment he recognized and emphasized the difference between the two phrases and proclaimed his abandonment of all that is embraced in that difference. * * *; cf. in case of disclaimer Altoona Publix Theatres v. American Tri-Ergon Corp., 294 U.S. 477 , 492, 493, 55 S.Ct. 455, 79 L.Ed. 1005. The difference which he thus disclaimed must be regarded as material, and since the amendment operates as a disclaimer of that difference it must be strictly construed against him.”
. The Restatement is as follows: “A trade secret may be a device or process which is patentable; but it need not be that. It may be a device or process which is clearly anticipated in the prior art or one which is merely a mechanical improvement that a good mechanic can make.”
. The parties to the litigation have not discussed, apparently deeming discussion unnecessary, the question of what law is applicable on the issue of unfair competition, the pendent or ancillary cause of action in this case. See the opinion of Mr. Justice Douglas in United Mine Workers of America v. Gibbs, 383 U.S. 715, 726, 86 S.Ct. 1130, 1139, 16 L.Ed. 2d 218 (1966), wherein it was stated that the justification for deciding a pendent proceeding “lies in considerations of judicial economy, convenience and fairness to litigants; if these are not present a federal court should hesitate to exercise jurisdiction of state claims even though bound to apply state law to them.” Citing Erie R. Co. v. Tompkins, 304 U.S. 64, 58 S.Ct. 817, 82 L.Ed. 1188 (1938). Cf. Taussig v. Wellington Fund, Inc., 313 F.2d 472, 475 (3 Cir. 1963) and Chief Judge Wright’s opinion in that case, 187 F.Supp. 179, 191, 193 (D.Del.1960). The court below made no findings as to whether the unfair competition phase of the litigation was multistate in effect or where the cause or causes of action allegedly arose. We conclude that it is not necessary to remand the cause to the court below to ascertain the applicable law of the State or States involved in the action. We are aware of no law, state or general, which would permit recovery on the unfair competition claim under the circumstances at bar.
In conclusion, we state that the evidence in the patent phase of the litigation and in the unfair competition phase are sufficiently integrated to permit the adjudication of the unfair competition cause.
