According to this press release, Macrovision has disclosed an adverse ruling regarding the priority of an InterTrust patent (Ginter, et al.) over claims in one of Macrovision's patent (Benson). The release says in part:
In a related action, the United States Board of Patent Appeals and Interferences issued a ruling on April 11, 2005 that was adverse to Macrovision in the Ginter v. Benson Patent Interference which is being litigated between Macrovision and InterTrust Technologies Corporation. The ruling concluded that certain of InterTrust's patent claims have priority over the Macrovision claims; however, this is an ongoing process with other portions of the interference action still under review by the Panel. The InterTrust interference action has no bearing on patents outside the U.S. and the essential international DRM patent applications mentioned above are proceeding to issuance in Europe and Japan, unaffected by the outcome of the U.S. patent interference action.
