Kason Industries, Inc. (Kason) appeals from the May 27, 1987, judgment of the United States District Court for the Eastern District of New York,
Background
The ’265 patent is for a self-closing, сam-lift hinge having a concealed light switch within the body of the hinge. The hinge is designed for use on the doors of refrigerators used in the food service industry. The application for the patent was filed on March 14, 1977, and the patent issued on April 17, 1979.
Standard-Keil Hardware Mfg. Co. (S-K) is a division of Buildex. S-K manufactures and sells hardware compоnents for the food service industry. Traulsen & Co. (Traulsen) manufactures refrigerators and is a leading customer of S-K.
In 1975, Traulsen’s Vice President of Manufacturing, Erich Maier, met with three S-K employees, including the named inventor of the '265 patent, Dermot Holden. Maier asked the S-K employees if it would be possible to incorporatе a light switch into their cam-lift hinge. Holden and SK’s engineers worked on the problem and came up with the hinge described in the ’265 patent.
Holden showed representatives of Traul-sen a working model of the hinge in October, 1975, about five months before the critical date of March 14, 1976. At a later meeting, Ed Czemiawski, a purchasing agent аt Traulsen, discussed with a representative of S-K the terms on which S-K would sell the hinge to Traulsen. In a Traulsen internal memorandum dated October 21,1975, Czemiawski reported the substance of the discussion to Maier which included an estimated cost of $2.80 per unit. A “Quotation” dated November 3, 1975, from Irving Brown, Sales Manager of S-K, to Czemiawski, was alsо produced from Traulsen’s corporate files. The quotation bears the notation “Terms of Sale” and lists a quantity of 50,000 pieces at a price of $2.84 each.
S-K agreed with Traulsen to file a patent application on the hinge and to sell the hinge exclusively to Traulsen. Traulsen in turn agreed to pay for cеrtain tooling expenses incurred by S-K and to use the hinge for its own use exclusively.
Kason appeals from the judgment with respect to the “on sale” bar, best mode, and inequitable conduct, and asks that we remand the case for determination of its entitlement to attorney fees under 35 U.S.C. § 285. Because we reverse the part of the judgment holding that the patent is not invalid under § 102(b), we need not consider the best mode issue. We remand the case, however, for a redetermination of inequitable conduct and for consideration of Kason’s request for attorney fees.
OPINION
A. “On Sale” Bar
An inventor loses his right to a patent if he has placed his invention “on sale in this country, more than one year prior to the date of the application for patent in the United States.” 35 U.S.C. § 102(b). The defendant, Kason, had the burden of proving that there was a definite sale
or offer to sell
more than one year before the application for the patent.
See UMC Elecs. Co. v. United States,
The district court found that Kason failed to demonstrate by clear and convincing evidence that S-K offered the hinge for sale before March 14, 1976. Although the issue of whether an invention is “on sale” is ultimately a question of law,
UMC,
*1463 1. “Clear and Convincing” Evidence of the Offer for Sale
Under 35 U.S.C. § 282, a patent is presumed valid, and an attack on its validity requires proof of facts by “clear and convincing evidence or its equivalent, by whatever form of words it may be expressed.”
American Hoist & Derrick Co. v. Sowa & Sons,
The district court found that “the available and credible evidence about the Brown quotation and the course of dealings between S-K and Traulsen failed to provide clear and convincing proof that S-K offеred the hinge for sale before March 14, 1976.” This finding, as far as it rests on disputed issues of fact, is clearly erroneous. In fact, all available evidence points to the opposite conclusion, clearly and convincingly we think, that S-K offered the hinge for sale several months before the critical date.
At trial, Kason rеlied on the deposition testimony of Irving Brown to show the offer for sale. Brown testified as follows:
Q. What was the result of the conversations between Traulsen and yourself, and Traulsen and Dermot Holden and Frank Loikitz? What was the result of that series of communications?
A. Well, there were several prototypes that were madе. They were presented with physical samples for evaluation and after the engineering people at Traulsen resolved, you know, or concluded what it was that they wanted incorporated in their hinge, we worked up a price and presented a price with Traulsen and we were successful in receiving the order.
Q. Did the prototypes work? Did Traulsen come back and indicate that they were satisfied?
A. Yes.
Q. The goal during this period that we’re discussing now was, I take it, sales of these hinges by Standard-Keil to Traulsen, am I correct?
A. Exactly.
Q. Do you recall Standard-Keil after the delivery of these working prototypes from Standard-Keil to Traulsen making a quote to Traulsen with a price?
A. Yes.
Q. And the quote, I take it would have specified quantities as well?
A. Yes.
Q. Was the quotation accepted?
A. Yes.
These events are corroborated by the Czemiawski memorandum dated October 21, 1975. This memorandum shows that the terms of the offer for sale had been discussed by that date. In it, Czemiawski reported to Maier that the “[t]otal cost ... is estimated at $2.80/ea.” and that samples of the hinge were available.
The most telling evidence, however, is the “Quotation” dated November 3, 1975, from Brown to Czemiawski. There is some dispute over this document because two different versions were produced from the respective records of Traulsen and S-K. Traulsen had оnly the first page of the two-page “Quotation” in its corporate files. This page, however, has the essential terms of quantity and price typed on it and bears the signature of Irving Brown. A copy of both pages of the quotation was produced from the personal files of Leon *1464 ard Berger, a regional salesmаn of S-K, which he kept in his home. This version, marked “COPY” and “CONFIDENTIAL,” is unsigned, but has the name “Irv Brown” typed below the signature line on page 2. Other than minor differences, such as handwritten notations, the first page of each is the same.
The district court accepted the authenticity of the Brown quotation and relied on it as “clear and convincing proof” in its later decision on the motion for relief from the judgment. The court did not give much weight to the quotation in its first opinion, however, as establishing an offer for sale, because there was “no testimony that it had been received by Traulsen before March 14, 1976 and no testimony as to when S-K began to ship the hinge with the switching feаture to Traulsen.”
It is not necessary that a sale be consummated for the bar to operate. Even if no delivery is made prior to the critical date, the existence of a sales contract or the signing of a purchase agreement prior to that date has been held to demonstrate an “on sale” stаtus for the invention.
J.A. LaPorte, Inc. v. Norfolk Dredging Co.,
The available evidence further indicates that Traulsen received the quotation before March 14, 1976. In his deposition testimony, Brown testified that the date on the quotation corresponded approximately to the time that it was created and sent to Traulsen. Brown admitted on cross-examination that it was possible, although doubtful, that the quotation was not sent to Traulsen beсause he had no personal recollection of it being sent. This supposition, however, which Buildex makes much of, is refuted by the fact that the signed first page of the quotation was produced from Traulsen’s corporate files in response to Kason’s subpoena. The page was attached to an internal Traulsen memorandum from Maier to Mr. Traulsеn in which Maier specifically referred to it as “their [S-K’s] quotation of 11/3/75.”
Considering all the evidence, we are convinced that the district court’s finding that Kason failed to prove by clear and convincing evidence that S-K offered the hinge for sale to Traulsen before March 14, 1976, is clearly erroneous.
See
Fed.R.Civ.P. 52(a). A finding is cleаrly erroneous when, although there is evidence to support it, the reviewing court is left with the definite and firm conviction that a mistake has been committed.
Anderson v. City of Bessemer City,
2. The Joint Development Argument
Once Kason showed that S-K made an offer to sell the hinge to Traulsen before the critical date of March 14, 1976, Buildex had to come forward with an explanation of the circumstances surrounding what would otherwise appear to be сommercialization prior to the grace period.
UMC,
On motion for relief from the judgment, the district court held that if the dealings between S-K and Traulsen before the critical date constituted an offer for sale, the invention was still not on sale within the *1465 meaning of the statute because it was not placed on sale to a person “outside the inventorship entity.” Although the court had earlier found that Holden was the sole inventor of the invention of the ’265 patent, it held that the invention was jointly developed by Traulsen and S-K and thus came within an asserted “joint development” exception to the on-sale bar. The court considered the policies behind the on-sale bar and determined that on the facts of this case “not one of the policy considerations that section 102(b) was designed to advance is implicated.”
We disagree. To begin, this court has never recognized a “joint development” exception to the “on sale” bar. We have dеliberately resisted rigid formulas and per se exceptions in applying § 102(b), instead considering the totality of the circumstances in each case.
See, e.g., Western Marine Electronics, Inc. v. Furuno Electric,
A sale or offer to sell must, of course, be between two separate entitiеs,
In re Caveney,
Nor does the exclusive selling arrangement between S-K and Traulsen excuse S-K’s commercialization prior to the one year grace period.
Cf. Caveney,
Equally mistaken is the district court’s reasoning that the policy expressed in
UMC,
S-K simply waited too long to file its patent application. Fred Weinmann, who made the decision to pursue patent protec *1466 tion on the hinge for S-K, admitted that “in those early days we probably waited a little bit longer to approach our patent people than we did later on.” That is obviously what happened here.
Accordingly, we conclude that the invention claimed in the ’265 patent was on sale within the meaning of § 102(b). Traulsen’s participation in the development of the hinge does riot excuse S-K’s attempt to commercialize the invention by offering it for sale more than one year priоr to the filing of the patent application.
B. Inequitable Conduct and Attorney Fees
The district court rejected Kason’s counterclaim for unenforceability of the ’265 patent for inequitable conduct (denominated “fraud”) in part because of its finding that Kason failed to show that the patented hinge was on sale more than one year before the filing of the patent application. Kason alleged that both the inventor Holden and Buildex, the corporate assign-ee, knew of the offer for sale before the critical date and intentionally withheld this material information from the Patent Office, the elements of what we now call “inequitable conduct.”
Although this issue may appear moot in view of our holding that the ’265 patent is invalid under § 102(b), the question of Holden’s and Buildex’s conduct in the procurement of the patent is still relevant to Ka-son’s request for attorney fees under 35 U.S.C. § 285, which was not decided by district court, as bearing on the question whether the case is “exceptional.”
See, е.g., Orthopedic Equip. Co. v. All Orthopedic Appliances, Inc.,
Conclusion
The judgment of the district court that the ’265 patent is not invalid under § 102(b) is reversed. The case is remanded to the district court for a redetermination of inequitable conduct and for consideration of Kason’s request for attorney fees.
