Interference No. 103,611 The junior party Stevens does not contend that it actually reduced to practice the invention of the count prior to its filing date. In order to prevail herein as the prior inventor, Stevens submits that it conceived the invention of the count as early as January 8, 1993 and was reasonably diligent from this date to its constructive reduction to practice on August 3, 1993. As between the parties, Miller asserts the earlier date of conception, as early as April 20, 1988. Miller will be entitled to prevail herein as first to conceive and first to reduce to practice (its May 25, 1993 filing date is a constructive reduction to practice) if it has established a date of conception prior to the January 8, 1993 date of conception alleged by Stevens. Count Ambiguity The count is the measure of the invention. Such being the case, we will address the position of Stevens that the count is ambiguous before proceeding to decide the issue of prior conception by Miller. The count is identical to claim 1 in the Stevens application. Based upon alleged different interpretations of the count presented by Miller and Stevens, the junior party contends that the count is ambiguous and should be interpreted in light of Stevens’ specification from which it originated. 5Page: Previous 1 2 3 4 5 6 7 8 9 10 11 NextLast modified: November 3, 2007
