Opinion

ORRICK, District Judge:

In this case involving the validity and enforceability of a number of patents on products and processes used in seaming carpets, at the close of the plaintiff’s case the trial judge held invalid a patent which was not in suit on the grounds of fraud against the Patent Office. The trial court then proceeded to declare invalid three other patents on the basis of the doctrine of unclean hands deriving from the fraud found in connection with the patent not in suit, and also on grounds of patent misuse. In finding fraud, the trial judge did not permit the plaintiff to prove good faith, nor did he require the defendant to prove by “clear and convincing evidence” that the fraud was either intentional or grossly negligent. In finding misuse, the trial judge failed to apply the appropriate standards for assessing the antitrust violations found, and specifically applied an erroneous standard to the question of whether the patents accumulated by the appellant were blocking patents. For these reasons, we reverse the judgment in favor of appellees and remand the case to the trial court for further proceedings not inconsistent with this Opinion.

I

Appellant, Carpet Seaming Tape Licensing Corporation (“Carpet Seaming”), a Texas corporation holding the patents here involved, brought these actions against appellees, Best Seam Incorporated (“Best Seam”), a California corporation making and selling hot-melt adhesive carpet seaming tape, Vectron Industries, Inc. (“Vectron”), another California corporation also making and selling hot-melt adhesive carpet seaming tape, and Eugene Tasse, the president of Vectron and, with his wife, the owner of all of its stock, for patent infringement.

A

The method for seaming carpets most accepted today is a face-seaming process using a hot-melt adhesive tape. Carpet sections are positioned pile-side-up on the floor, and the edges to be joined are rolled back just far enough to allow placement of the tape beneath the seam. The adhesive which is in solid form on the tape is then melted, and the carpet edges pressed down upon it for bonding as the adhesive resolidifies. This system has largely supplanted sewing as well as back-seaming (a process in which carpet sections are turned pile-side-down, and the seaming work is performed on the back of the carpet) since it allows the work to be done quickly and without the need for moving cumbersome sections of carpet once they have been positioned as the installer desires.

The tape utilized in this process is composed of three elements. The uppermost element is a layer of hot-melt adhesive. Hot-melt adhesive is solid and nonadhesive at room temperature. When heated, it becomes molten and forms a bond which it retains when cooled and resolidified. During the manufacturing of the tape, the adhesive layer is bonded to the second element of the tape, a layer of synthetic mesh which lends the tape strength. The seaming process actually involves the bonding of two pieces of carpet to this single strip of mesh. The final element of the tape is a paper barrier which prevents the adhesive layer from bonding to whatever lies beneath it when it is heated. As a further refinement, the adhesive layer is embossed into parallel ridges which melt into a single smooth layer of adhesive at the appropriate heat for bonding. The embossing feature provides the worker using the tape with a quick visual index for gauging adequate heating of the adhesive.

B

Of the four patents directly at issue before the district court, three were originally obtained by Charles D. Burgess. Burgess “038” covers the three-element tape described above without the added feature of embossed ridges. Burgess “876” covers the seaming process described above using the “038” tape. Burgess “830” describes the process for manufacturing the “038” tape. The fourth patent (the “Winkler patent”) was obtained by Alexander Winkler and [1136]*1136covered tape using embossed ridges. Two other patents also .involved were Burgess “703”, a predecessor of the Burgess patents outlined above, which describes a process for seaming carpets using a two-element tape like the “038” tape but without the paper barrier, and a patent issued to Michael L. Clymin (the “Clymin patent”) covering a three-element tape in which the adhesive is deposited in unconnected parallel bands on the tape rather than as ridges upon a smooth layer of adhesive as in the Winkler patent.

Charles Burgess in March, 1966, produced a two-element tape and process which could be used successfully to seam carpets, but which required placing newspaper as a barrier beneath the tape to prevent the adhesive from sticking to the floor or padding below the tape. It was only on concrete floors that this step of placing newspapers beneath the two-element tape was not required, since the adhesive used by Burgess would not adhere to concrete. On March 14, 1966, Burgess sent himself a letter by registered mail in which he described his two-element process, and on March 18,1966, he filed a patent application on the process which eventually resulted in issuance on December 10, 1968, of the “703” patent described above. Neither in his application nor in the letter did Burgess disclose the step of placing newspapers beneath the tape, although he regularly used this step in practicing and demonstrating his process. The trial court found that the use of such a barrier was known in the art of carpet seaming for many years prior to March, 1966 (Finding of Fact No. 101), Carpet Seaming Tape Licensing Corp. v. Best Seam Inc., 197 U.S.P.Q. 230, 240 (C.D.Cal.1977) (hereinafter cited as Carpet Seaming), and that omission of this step, which it found necessary to the practice of the two-element process, constituted fraud by Burgess on the Patent Office invalidating not only the “703” patent, but the dther three Burgess patents as well.

In May, 1966, Burgess added a paper barrier web as an element of his tape, and on December 6, 1966, he filed a second patent application, a continuation-in-part to his March 18 application, for patents on the three-element tape described above and the processes for making and using it. A continuation-in-part is an application filed during the lifetime of an earlier application by the same applicant repeating portions or all of the earlier application and adding matter not disclosed in the earlier application. The same Patent Examiner searched both applications together. After further Patent Office action, the December 6 application resulted in the issuance of the “038” patent on September 3, 1968, the “876” patent on October 13, 1970, and the “830” patent on February 16, 1971.

In January, 1968, Burgess sold his business and the pending applications to Giffen Industries, Inc. (“Giffen”), which subsequently transferred them to appellant.

Besides obtaining exclusive licenses for the Burgess patents, appellant also obtained exclusive licenses for the Clymin patent1 and the Winkler patent.2

[1137]*1137The Burgess, Winkler, and Clymin patents have been available for licensing at a four percent royalty rate for flat tape and a five percent rate for embossed and ribbed tape.
