In re: AT&T Intellectual Property II

by
AT&T’s patent is directed to a method of compressing and transmitting transform coefficients in a manner that does not rely on scanning the coefficients in any particular order; all of the coefficients in a block are transmitted at once. Days before the America Invents Act inter partes review procedures went into effect, LG requested inter partes reexamination of the patent, alleging anticipation. Before the PTO decided whether to initiate reexamination, LG asked the PTO to suspend its rule prohibiting a requester from filing documents between requesting inter partes reexamination and the PTO’s initial office action on the merits so that it could file a second request, requesting denial of its initial request. LG did not withdraw, nor did it withdraw its reexamination request. The PTO granted LG’s initial request and declined to suspend the rules. The examiner found new grounds of rejection. While discussions between AT&T and the examiner were ongoing, LG withdrew. The examiner suspended the prohibition against interviews during inter partes reexamination proceedings. Before any amendment, the examiner issued an Action Closing Prosecution that explained a different basis for finding the patent anticipated. The Board and the Federal Circuit affirmed. The Board did not exceed its statutory authority when instituting the reexamination and substantial evidence supported the finding of anticipation.
