Netscape Communications Corp. v. Konrad
Netscape Communications Corp. v. Konrad, 295 F.3d 1315 (Fed. Cir. 2002),〔(Netscape Communications Corp. v. Konrad, 295 F.3 1315 (Fed. Cir. 2002) )〕 was a decision of the United States Court of Appeals for the Federal Circuit. It affirmed that public use or commercialization of an invention more than one year prior to the filing date will cost the inventor his patent rights (see also ). The inventor in this case was Allan M. Konrad, a Lawrence Berkeley National Laboratory employee who devised and implemented a method for accessing and searching data objects stored on a remote computer (U.S. patents 5,544,320; 5,696,901; 5,974,444). Netscape moved to invalidate Konrad's patents in U.S. district court immediately after Konrad filed a patent infringement suit against Netscape customers. The district court concluded that Konrad's patents were invalid because they did not meet the public-use and on-sale bar eligibility criteria of .
In particular, the district court found that Konrad (1) placed his invention in the public domain by demonstrating it to others without a confidentiality agreement and (2) tried to sell it to other legal entities, both more than one year before he filed for the patent. The appeals court, upon review, affirmed the district court decision for the same reasons.
== Background ==
Alan M. Konrad owns U.S patents 5,544,320;〔 5,696,901;〔 5,974,444;〔 all concerning a system for accessing and searching a database residing on a remote computer. On February 8, 2000, Konrad filed a patent infringement suit in U.S. District Court for the Eastern District of Texas against thirty-nine customers of Netscape Communications Corp., including Microsoft Corp. and America Online, Inc. Netscape, acting in the interest of its customer relationships, asked the U.S. District Court for the Northern District of California to invalidate Konrad's patents via a declaratory judgment. Netscape argued that Konrad's system was in public use and on-sale before Jan. 8, 1992—exactly one year before he filed the first patent for this invention. According to , a patent is valid unless "the invention was patented or described in a printed publication in this or a foreign country or in public use or on sale in this country, more than one year prior to the date of the application for patent in the United States". Netscape prevailed in its argument; the district court judged the patent to be invalid on June 18, 2001. Konrad then appealed the decision to the U.S Court of Appeals for the Federal Circuit.
