(171) Treatment of Non-Conforming Requests to Revoke or Invalidate U.S. Patents The Patent and Trademark Office (PTO) has received an extremely large number of contemporaneously filed form letters requesting that certain U.S. patents be revoked or invalidated. These form letters, while identifying U.S. patents which are believed to be invalid, do not include any prior art patents and/or printed publications to support such belief. The bases for challenging patentability within the PTO are: (1) Submission of a protest under 37 CFR 1.291; (2) Submission of prior art under 35 U.S.C. 301; and (3) Submission of a third party reexamination request under 35 U.S.C. 302. These form letters do not comport with any one of the bases for challenging patentability within the PTO. To respond individually to these form letters (by pointing out deficiencies and forwarding them to the patentee) would be unduly burdensome to the PTO. Therefore, these form letters will not be responded to individually and will not be placed in the patent files. August 17, 1998 STEPHEN G. KUNIN Deputy Assistant Commissioner For Patent Policy and Projects [1214 OG 77]
