1308 (Fed. Cir. 1989), parties involved in interferences, including now Livak, have continually told us that we have to decide patentability when it (1) is raised, (2) fully briefed and (3) evidence has been submitted. Section § 135(a) itself says that the board "may" determine questions of patentability. A review of legislative activity leading up to the 1984 amendment 7 to § 135(a) should convincingly demonstrate that "may" does not mean "shall". H.R. 6286, 98th Cong., 2d Sess., § 202 (Sept. 20, 1984), as introduced by then Congressman Kastenmeier, sought to amend § 135(a) and provided that "The Board of Patent Appeals and Interferences shall determine questions of priority of the inventions and may determine questions of patentability." (Emphasis added). On the other hand, S. 1538, 98th Cong., 2d Sess., § 14(a) (Calendar No. 1016) (June 23, 1983), as introduced by then Senator Mathias,8 also sought to amend § 135(a) and provided that "The Board of Patent Appeals and Interferences shall determine the priority and patentability of invention in interferences." (Emphasis added). A similar provision appeared in S. 1535, 98th Cong., 1st Sess., § 19(a) (Calendar No. 1330) (June 23, 1983).9 Ultimately, the House, as opposed to the Senate, version of the amendment to § 135(a) became law. 7 Patent Law Amendments Act of 1984, Pub.
