Share Article

Today, the United States Patent Office (PTO), through its specialized Central Reexamination Unit, issued a Right of Appeal Notice in the pending reexamination of Tessera's litigated US Patent No. 6,433,419 (the '419 patent). This patent has been the subject of earlier PTO rejections, and the issued Right of Appeal Notice by the PTO today maintains the previous rejections of all claims of the '419 patent which are in reexamination.

This latest action by the PTO ends prosecution on the merits of the '419 patent. Tessera may appeal this decision to the Board of Patent Appeals and Interferences and to the Courts. The Requester of the inter partes reexamination may also participate in and put forth arguments against the '419 patent in any such appeal taken by Tessera. If the PTO's decision is not reversed on appeal, all claims of the '419 patent subject to the reexamination will be cancelled by the PTO.

The reexaminations were requested by Siliconware Precision Industries Co. Ltd. taking advantage of the Patent Office's new inter partes reexamination procedures for addressing validity issues.

Gregory V. Novak is leading the reexaminations with James P. Murphy and Suni Sukduang at Novak Druce + Quigg LLP.
