Clarification of Filing Date Requirements for Ex Parte and Inter Partes Reexamination Proceedings

The United States Patent and Trademark Office (Office) is revising the rules of practice relating to the filing date requirements for ex parte and inter partes reexamination proceedings for consistency with the provisions of the patent statute governing ex parte and inter partes reexamination proceedings. The Office is specifically revising the rules to require that a request for ex parte reexamination or for inter partes reexamination must meet all the applicable statutory requirements before a filing date is accorded to the request for ex parte reexamination or for inter partes reexamination.
