According to the Patent Docs, "More Patentees Have Followed Wyeth's Lead in Seeking Additional PTA." They also report that the USPTO filed a Notice of Appeal in the District Court for the District of Columbia on that court's September 30th decision in Wyeth v. Dudas. The Wyeth court determined that the U.S. Patent and Trademark Office had misconstrued 35 U.S.C. § 154(b)(2)(A), and as a result, had denied Wyeth a portion of patent term to which it was entitled under U.S. Patent Law.
