Allan M. Konrad appeals from the judgment of the United States District Court for the Northern District of California granting Netscape Communications Corp., Microsoft Corp., and America Online, Inc. (“Netscape”) summary judgment that U.S. Patent Nos. 5,544,320 (the “'320 patent”), 5,696,901 (the “'901 patent”), and 5,974,444 (the “'444 patent”) are invalid under the public use and on-sale bars of 35 U.S.C. § 102(b). Netscape Communications Corp. v. Konrad, No. C 00-20789 JW (N.D. Cal. April 2, 2001). Because we agree with the district court that Konrad has not raised a genuine issue as to any material fact pertaining to pre-critical date demonstrations, public uses by others, and his commercial offer to create the high energy physics remote database object, we affirm.
Background
Konrad is the owner of the '320, '901, and '444 patents, all directed to systems that allow a computer user to access and search a database residing on a remote computer. He began working as a staff scientist for the Lawrence Berkeley Laboratory in 1977, where he studied how an individual computer workstation user could obtain services from a remote computer. On September 26, 1990, while working with Cynthia Hertzer, a Lawrence Berkeley Laboratory staff assistant, Konrad successfully tested the remote database object system. The first prototype of this system was configured to access Lawrence Berkeley Laboratory’s STAFF database from a remote workstation. The Lawrence Berkeley Laboratory STAFF database resided on an IBM mainframe computer on the Berkeley campus of the University of California. A local starter portion of the remote database object system prototype was created for installation on users’ personal computers to allow the display of an icon by which the user could access the remote database. In 1991, Konrad and Hertzer adapted the Lawrence Berkeley Laboratory STAFF remote database ob
The '320 patent, Konrad’s first issued patent, is a continuation of an application filed on January 8, 1993. The '901 patent is a continuation of the '444 patent application, which is a continuation of the '320 patent application. Thus, the earliest filing date that Konrad is entitled to is January 8, 1993, making the critical date for the public use and on-sale inquiry January 8,1992.
On February 8, 2000, Konrad filed a patent infringement suit in the District Court for the Eastern District of Texas, alleging that thirty-nine commercial entities, all customers of Netscape, had infringed the '320, '901, and '444 patents. Citing threatened customer relationships, Netscape filed a declaratory judgment action against Konrad in the District Court for the Northern District of California, seeking a judgment of invalidity, nonin-fringement, and unenforceability. Netscape moved for partial summary judgment that prototypes of the invention were in public use or on-sale under 35 U.S.C. § 102(b) based on Konrad’s activities prior to January 8, 1992. The California district court entered partial summary judgment for Netscape concluding that: (1) Konrad’s demonstration of the claimed invention to Shuli Roth and Dick Peters, University of California computing personnel, without any obligation of confidentiality was a public use; (2) his demonstration of the high energy physics remote database object to the Stanford Linear Accelerator Center in conjunction with the use of the remote database object by University Research Association Superconducting Super Colli-der Laboratory employees was a public use; and (3) his offer to create the high energy physics remote database object system for the University Research Association Superconducting Super Collider Laboratory in exchange for four months full-time employment or no more than $48,000, and his stipulation that the reduction to practice of the invention occurred prior to that event, satisfied the on-sale bar. Konrad stipulated that all of the claims of the patents in suit would be invalid if the court were to find that his activities qualified as prior art. In view of this stipulation, on June 18, 2001, the district court entered the parties’ joint stipulation for final judgment on invalidity. We have jurisdiction pursuant to 28 U.S.C. § 1295(a)(1).
Discussion
We review a district court’s grant of summary judgment de novo. Bose Corp. v. JBL, Inc.,
Under 35 U.S.C. § 102(b), “[a] person shall be entitled to a patent unless ... the invention was in public use or on
I.
Public use includes “any use of [the claimed] invention by a person other than the inventor who is under no limitation, restriction or obligation of secrecy to the inventor.” Petrolite Corp. v. Baker Hughes Inc.,
The law recognizes that an inventor may test his invention in public without incurring the public use bar. “Experimental use negates public use; when proved, it may show that particular acts, even if apparently public in a colloquial sense, do not constitute a public use within the meaning of section 102.” Baxter Int’l, Inc. v. Cobe Labs., Inc.,
We look to the totality of the circumstances when evaluating whether there has been a public use within the meaning of section 102(b). Sinskey v. Pharmacia Ophthalmics Inc.,
A.
Konrad argues that the district court erred in determining that his 1991 demonstration of the Lawrence Berkeley Laboratory STAFF remote database object to University of California computing personnel was an invalidating public use. He maintains that the invention disclosure he submitted to the Lawrence Berkeley Laboratory patent department in October of 1990, established an expectation of confidentiality from Roth and Peters. Netscape responds that the district court correctly determined that Konrad failed to establish a genuine issue of material fact that the demonstrated prototype was not in public use, and was prior art for the purpose of evaluating the validity of the patents in suit.
We agree with Netscape. Konrad did not show that Roth or Peters were ever made aware of any requirement of confidentiality or even apprised of the invention disclosure forms that he submitted to the Lawrence Berkeley Laboratory patent department. He also did not make any dis-cernable effort to inform the 1991 demonstration attendees of the requirement of confidentiality, or otherwise indicate to them that they would owe him a duty of confidentiality.
“In some circumstances, ... it would be significant that no pledge of confidentiality was obtained from the user.” TP Labs., Inc.,
Next, Konrad argues that the 1991 demonstration was not a public use because he did not disclose every limitation of his invention, particularly the starter client of the remote database object, to Roth and Peters. • We are not persuaded. Section 102(b) may bar patentability by anticipation if the device used in public includes every limitation of1 the later claimed invention, or by obviousness if the differences between the claimed invention and the device used would have been obvious to one of ordinary skill in the art. See Lough v. Brunswick Corp.,
Konrad also argues that the 1991 demonstration was an experimental use for the purpose of obtaining technical support to incorporate upgrades and make the invention run more smoothly. To establish that -an otherwise public use does’ not run afoul of section 102(b), it must be shown that the activity was “substantially for purposes of experiment.” Baker Oil Tools, Inc.,
Konrad also argues that at all relevant times he took affirmative steps to maintain control of his invention and questions the substantiality of the evidence to the contrary. He asserts that Moleculon Research Corp. v. CBS, Inc.,
B.
Konrad argues that the district court erred in determining that the demonstration of the high energy physics remote database object system to Stanford Linear Accelerator Center and use by University Research Association Superconducting Super Collider Laboratory employees were invalidating public uses under section 102(b). He contends that the Department of Energy owned all of the intellectual property rights to the invention, and that all Department of Energy laboratory employees were under an obligation of confidentiality to the government during all demonstrations and testing. To support this contention, Konrad relies on the testimony of Paul Martin concerning the invention disclosure rules of Lawrence Berkeley Laboratory, and the contract between Lawrence Berkeley Laboratory and the Department of Energy. Konrad also relies on the testimony of Louise Addis, a librarian at Stanford Linear Accelerator Center, to support his position that he maintained control over his invention through the use of passwords.
Konrad tries to cloak his failure to protect the confidentiality of his invention and maintain control of others use by arguing that because the Department of Energy was providing the funding for his project, it ultimately owned the invention; therefore, anyone working on the remote database object server was subject to Department of Energy confidentiality. This argument is without merit. Konrad is the
Konrad says that the demonstration of the high energy physics remote database object system at the Stanford Linear Accelerator Center was not enabling because there was no evidence that the source code was delivered to the Superconducting Super Collider Laboratory before the critical date. However, it is the claims that define a patented invention. See Constant v. Advanced Micro Devices, Inc.,
II.
The on-sale bar applies when the invention is the subject of a commercial offer for sale, and is ready for patenting before the critical date. Pfaff v. Wells Electronics, Inc.,
Konrad primarily argues that the court erroneously concluded that his offer to make the high energy physics remote database object for the University Research Association Superconducting Super Collider Laboratory in .exchange for four months full time employment or no more than $48,000 constituted a commercial offer for sale. He contends that the memorandum purchase order memorializing the agreement is not a contract, but merely an accounting instrument used to track the transfer of .research funds between two Department of Energy laboratories, and therefore did not involve the sale of a commercial embodiment of the invention.
Netscape responds that the memorandum purchase order is only one of the contemporaneous documents relied on by the district court in its analysis of whether Konrad’s offer was within the purview of the on-sale bar of section 102(b). It contends that the memorandum purchase order is an offer to sell a' working prototype of'the remote database object to the Stanford Linear Accelerator Center and qualifies as such by listing the product to be purchased, the delivery date, and the price. The district court observed that Konrad had extended commercial offers for the sale of the remote database object prototype to the University Research Association Superconducting Super Collider Laboratory in September of 1991. The court also determined that he failed to establish a genuine issue of material fact that the commercial offer -between Lawrence Berkeley Laboratory and University Research Association Superconducting Super Collider Laboratory involved two Department of Energy controlled entities.
The evidence on summary judgment evinces that the memorandum purchase order memorialized Konrad’s proposal, which was accepted by Lawrence Berkeley Laboratory subject to revisions, to provide a working prototype of a remote database object configured to support the high energy physics database at Stanford Linear Accelerator Center for $48,000. But, we have held that a sale or offer to sell under section 102(b) must be between two separate entities. In re Caveney,
The only remaining question is whether the invention was ready for patenting at the time of the offer for sale. Konrad admitted that the reduction to practice date was on or about September 26, 1990, before the critical date, and his disclosure
Conclusion
Accordingly, the judgment of the United States District Court for the Northern District of California is affirmed,
AFFIRMED.
Notes
. Konrad also appeals the California district court's determination that his pre-critical date demonstrations and offer to create the remote database object were material under 37 C.F.R. § 1.56. Because the patents at issue are invalid we do not reach the issue of materiality.
