(Paper 3), the parties have notified the board of the abandoned status of the Waterman application. An interference may be declared between a pending application and an unexpired patent when the Commissioner is of the opinion that the application and patent claim the same patentable invention. 35 U.S.C. § 135(a); 37 CFR § 1.606. B. Discussion The Patent Statute (35 U.S.C. § 135(a)) does not authorize an interference between an abandoned application and an unexpired patent. Since the Waterman application was abandoned as of the date the interference was declared, it follows that the board lacked subject matter jurisdiction over the interference. Compare Petrie v. Welsh, 21 USPQ2d 2012 (Bd. Pat. App. & Int. 1991) (patent versus application interference terminated for lack of subject matter jurisdiction where it was discovered patent had expired prior to declaration of interference). In light of the board's lack of subject matter jurisdiction in this interference, and notwithstanding the ORDER entered 9 February 2000 (Paper 2), there will be no further evaluation of the Rule 608(b) showing which has been presented by Waterman. The board appreciates the prompt manner in which counsel have called our attention to the abandoned status of the Waterman application. - 2 -Page: Previous 1 2 3 4 NextLast modified: November 3, 2007
