Narrative Opinion Summary
In this case, the court addressed motions for partial summary judgment concerning allegations of inequitable conduct and Walker Process fraud related to U.S. Patent Nos. 6,502,917 and 6,550,902. Ninestar Technology and Dataproducts USA sought to declare these patents unenforceable, asserting that Seiko Epson Corporation failed to disclose significant prior art during the patent prosecution process. Specifically, Ninestar argued that Epson withheld a material reference from its WO '352 Application, which was crucial to the patent's issuance. However, the court granted Epson's Cross-Motion for Partial Summary Judgment, finding no inequitable conduct or fraud. The court determined that Epson's disclosure of the WO '352 Application's abstract, along with accessible translations, made the withheld information cumulative, thus not material. Additionally, no intent to deceive the Patent and Trademark Office was found. The court's decision reflects tightened standards from the Federal Circuit regarding inequitable conduct claims, concluding that Ninestar's motion lacked substantial evidence. The outcome maintained the enforceability of Epson's patents and rendered the prior order to stay antitrust issues moot.
