Tech Companies Defend EMC in Patent Case

Six of the biggest names in technology have lined up behind EMC Corp. and other companies caught up in a patent case that highlights a controversy over filing infringement charges against many unrelated defendants. Microsoft Corp., Hewlett-Packard Co., Oracle Corp., Cisco Systems Inc., Yahoo Inc. and SAP AG's U.S. unit filed a brief in the U.S. Court of Appeals for the Federal Circuit, expressing support for EMC's appeal of a patent case brought by Oasis Research LLC. Oasis filed the suit in 2010 in federal court in the Eastern District of Texas against 18 defendants.
