Affymetrix Provides Update on Litigation Against Incyte (http://biz.yahoo.com/prnews/990412/ca_affymet_2.html ) SANTA CLARA, Calif., April 12 /PRNewswire/ -- Affymetrix, Inc. (Nasdaq: AFFX - news) reported today that the United States Patent and Trademark Office (''PTO'') has issued an ''Order to Show Cause'' in connection with Incyte's request to declare interferences between the narrower claims of Affymetrix' issued United States Patent No. 5,800,992 (the '''992'' patent, relating to ''two color assays'' patent) and to the claims of its United States Patent 5,744,305 (the '''305'' patent, relating to arrays of nucleic acids with more than 400 probes per square centimeter), and a pending patent application licensed to Incyte Parmaceuticals, Inc. (Nasdaq: INCY - news). Vern Norviel, Senior Vice President and General Counsel of Affymetrix stated, ''We welcome the involvement of the Patent Office in clarification of Affymetrix' patent rights, as we originally sought to provoke an interference with the Incyte patent when we filed the application that matured into the '992 patent. We believe that the PTO is well equipped to resolve the matters raised by Incyte and that, following these proceedings, the PTO will have disposed with most, if not all, of Incyte's defenses to our infringement claims against them as to these particular claims.'' Mr. Norviel noted that the PTO's actions also have the following effects: -- Affymetrix' claim against Incyte based on U.S. Patent No. 5,445,934 (the '''934'' patent directed to arrays of nucleic acids with more than 1,000 probes in a square centimeter) was not affected by the interference. Mr. Norviel noted that the PTO specifically rejected one of Incyte's main defenses on the '934 patent, finding that oligonucleotides are polynucleotides; -- As to the '992 two color patent, the broadest claims of this patent (which are infringed by Incyte) are not part of the interference. Incyte has provided no basis for believing that these uninvolved claims are not both valid and infringed; and -- Even as to the particular claims that are involved in the patents, Affymetrix was designated as the senior party. Normally the senior party wins an interference because of the heavy burdens of proof on the junior party. At present, it is not known whether the PTO's action will have any effect on the scheduled hearing of Affymetrix' Motion for a Preliminary Injunction against Incyte, which is set for April 30. The PTO order requires Incyte to produce all evidence it has asserted in support of its motion and then allows Affymetrix to file an opposition to Incyte's request in order to enable the PTO to determine whether Incyte's evidence is sufficient to warrant a finding that Incyte has made a ''prima facie'' showing in support of its interference request. Even as to the few claims that are involved in the interference, the normal interference proceedings will not continue if Affymetrix is able to demonstrate that Incyte's heavy burden of proof has not been met. The PTO order sets forth a timeline for a ruling on these proceedings in late summer 1999, which Affymetrix believes will likely strengthen its patent portfolio.
