Barnes & Noble’s Patent-Misuse Claim Against Microsoft Rejected

Barnes & Noble Inc.’s claim that Microsoft Corp. is misusing patents to undermine competition from Google Inc.’s Android operating system was thrown out by a U.S. trade judge.

U.S. International Trade Commission Judge Theodore Essex rejected today Barnes & Noble’s arguments the patents should be held unenforceable, Microsoft Deputy General Counsel David Howard said in a statement. Essex’s decision is subject to review by the six-member commission, which has the power to block imports of products that violate U.S. patent rights.
