January 29, 2010: The USPTO announced the following interim procedure to request PTA recalculation under Wyeth: - Patentees can request PTA recalculation under Wyeth without a fee or petition.
- The procedure is only available for patents issued prior to March 2, 2010.
- A recalculation request must be filed no later than 180 days after the patent issue date.
- The interim procedure is only available if the sole basis for alleged error is the Wyeth issue.
- Form PTO/SB/131 has been made available to make the recalculation request.
- The USPTO has submitted a Federal Register Notice setting forth details.
One leading commentator, however, has questioned the USPTO's authority to provide this interim procedure. Prudent applicants are advised to recheck all parts of USPTO-calculated PTA, observing the formal deadlines under 35 USC 154(b)(4) and 37 CFR 1.705 where possible. Otherwise, applicants may have limited recourse to correct erroneous USPTO recalculations, especially if the recalculation is made more than 180 days after issue.
January 22, 2010: The USPTO has announced that it, and the Department of Justice, have decided not to seek further review of the Federal Circuit's decision in Wyeth v. Kappos. The USPTO further stated it is preparing guidance for expediting requests for PTA recalculation in light of Wyeth, which will be issued as soon as possible. The USPTO again reminds applicants and patent owners dissatisfied with a USPTO-calculated PTA of "the requirement to seek review of that determination within 180 days of patent issuance and the time periods set in the implementing regulations. See 35 USC sec. 154(b)(4) and 37 CFR 1.705." For patents outside the listed deadlines, perhaps some practitioner will succeed in retroactively obtaining the benefit of Wyeth (e.g., certificate of correction, petition to director, equitable tolling), but that path is less certain.
January 12, 2010: While not yet implemented, the USPTO has announced it is in the process of changing its PTA calculation algorithm to conform with Wyeth, pending a determination by the Solicitor General of whether to seek further review of the Federal Circuit holding. Until the change is implemented and tested, Applicants are advised to carefully check USPTO-calculated PTA under Wyeth. The USPTO reminds applicants and patent owners dissatisfied with a USPTO-calculated PTA of "the requirement to seek review of that determination within 180 days of patent issuance and the time periods set in the implementing regulations. See 35 USC 154(b)(4) and 37 CFR 1.705." For patents outside the listed deadlines, perhaps some practitioner will succeed in retroactively obtaining the benefit of Wyeth (e.g., certificate of correction, petition to director, equitable tolling), but that path is less certain.

January 7, 2010: [Updated] Today, the Federal Circuit unanimously affirmed the DC District Court ruling in Wyeth, overturning a USPTO statutory interpretation that resulted in reduced terms for tens of thousands of US patents. This holding, long advocated by the founders of PatentTerm Online, LLC, will result in significantly greater PTA for many patent applications pending more than three years.

August 24, 2009: [Wyeth Briefing Update] Briefing was completed in Wyeth v. Kappos, No. 09-1120 (Fed. Cir.), on June 22, 2009. Oral argument has been scheduled for October 7, 2009.
June 5, 2009: We have confirmed that the USPTO is rejecting some Applications for PTA requesting additional days under the Wyeth ruling. To seek review of a USPTO PTA determination, applicants must file a civil action in the DC District Court within 180 days after the grant of the patent. See 35 USC 154(b)(4)(A). This deadline may apply even where the USPTO has not acted on a pending PTA petition.
November 28, 2008: The USPTO appealed the ruling in Wyeth et al. v. Dudas, 580 F.Supp.2d 138 (D.D.C. 2008). The initial appeal was to the DC Circuit Court, but was subsequently transferred to the Federal Circuit.
November 25, 2008: On November 7, 2008, Ironwood Pharmaceuticals filed suit against the USPTO seeking additional PTA under Wyeth. Of note, the applicant proceeded directly to the DC District Court within 180 days of issue under 35 USC 154(b)(4)(A) without first seeking correction in the USPTO under 37 CFR 1.705.
October 2, 2008: There has been a significant development in PTA law. On September 30, 2008, the DC District Court overturned the USPTO's interpretation of 35 USC 154(b)(2)(A) (the "Actual Delay" limitation) in Wyeth et al. v. Dudas, 580 F.Supp.2d 138 (D.D.C. 2008).
