Patent Reexaminations, Supplemental Examinations, and Post Patent Submissions

The USPTO is required by 35 U.S.C. 131 and 151 to examine applications and, when appropriate, allow applications and issue them as patents. Chapter 30 of Title 35 U.S.C. provides that any person at any time may file a request for reexamination by the USPTO of any claim of a patent on the basis of prior art cited under the provisions of 35 U.S.C. 301. Once initiated, the reexamination proceedings under Chapter 30 are substantially ex parte and do not permit input from third parties. The regulations outlining ex parte reexaminations are found at 37 CFR 1.510-1.570. In addition, 35 U.S.C. 257 permits a patent owner to request supplemental examination of a patent by the USPTO to consider, reconsider, or correct information believed to be relevant to the patent. The regulations outlining supplemental examination are found at 37 CFR 1.601-1.625. The Leahy-Smith America Invents Act terminated inter partes reexamination effective September 16, 2012. However, inter partes reexamination proceedings based on inter partes reexamination requests filed before September 16, 2012, continue to be prosecuted. Therefore, this information collection continues to include items related to the prosecution of inter partes reexamination proceedings. The regulations outlining inter partes reexamination are found at 37 CFR 1.903-1.959. The provisions of 35 U.S.C. 301 and 37 CFR 1.501 govern the ability of a person to submit into the file of an issued patent (1) prior art consisting of patents or printed publications which the person making the submission believes to have a bearing on the patentability of any claim of the issued patent and (2) statements of the owner of the issued patent filed in a proceeding before a Federal court or the USPTO in which the owner of the issued patent took a position on the scope of any claim of the issued patent. This information collection covers information contained in: (1) requests for ex parte reexamination, (2) requests for supplemental examination, (3) submissions made by patent owners and third-party requesters related to the prosecution of an ex parte or inter partes reexamination proceeding, (4) information submitted by the public to aid in ascertaining the patentability and/or scope of the claims of the issued patent, and (5) information submitted by patent owners regarding a position taken before the USPTO or a Federal court regarding the scope of any claim in their issued patent. The USPTO’s use of the statements of the patent owners ((5) above) will be limited to determining the meaning of a patent claim in ex parte reexamination proceedings that already have been ordered and in inter partes review and post grant review proceedings that already have been instituted. The purpose of this information collection is to facilitate requests for ex parte reexamination and supplemental examination, to facilitate prosecution of reexamination and reissue proceedings, and to ensure that the associated documentation is submitted to the USPTO, and to permit relevant post-patent prior art and claim scope information to be entered into a patent file.
