Discovision Sues: Discovision Associates of Costa Mesa said Monday that it is suing a compact disc manufacturer for allegedly violating a patent held by Discovision related to optical disc manufacturing.

DVA filed a suit Friday in federal court in Charlottesville, Va., against Nimbus Records Inc. Dennis Fischel, president of DVA, said in a statement that efforts to sell a license to Nimbus failed.

DVA’s patent covers the way digital data is encoded upon an optical disc, Fischel said. DVA is a licensing company and a subsidiary of Tokyo-based Pioneer Electronic Corp.

DVA is also suing parent company Nimbus Records Ltd, which is a 75%-owned division of Maxwell Communications Corp. plc in England. Representatives for Nimbus Records could not be reached for comment.
