Appeal 2006-0959 Application 10/075,914 reinforcement to prevent collapse. Our review of the specification uncovers no disclaimer or disavowal of the ordinary and customary meaning of the term “patency.” In fact, the use of the term in Appellant’s specification is consistent with the ordinary and customary meaning. In re Paulsen, 30 F.3d 1475, 1480, 31 USPQ2d 1671, 1674 (Fed. Cir. 1994)(“An inventor may choose to be his own lexicographer if he defines the specific terms used to describe the invention ‘with reasonable clarity, deliberateness, and precision.’”). Our reviewing court counsels us that the PTO should avoid the temptation to limit broad claim terms solely on the basis of specification passages and tells us that, absent claim language carrying a narrow meaning, the PTO should only limit the claim based on the specification when those sources expressly disclaim the broader definition. In re Bigio, 381 F.3d 1320, 1324-25, 72 USPQ2d 1209, 1210-11 (Fed. Cir. 2004). During prosecution, Appellant is free to amend the claims to include language carrying a narrower meaning. “As an initial matter, the PTO applies to the verbiage of the proposed claims the broadest reasonable meaning of the words in their ordinary usage as they would be understood by one of ordinary skill in the art, taking into account whatever enlightenment by way of definitions or otherwise that may be afforded by the written description contained in the applicant's specification.” In re Morris, 127 F.3d 1048, 1053-54, 44 USPQ2d 1023, 1026-1028 (Fed. Cir. 1997). We, therefore, determine that “maintaining patency” encompasses maintaining the stent open, expanded, and unblocked by any method including by preventing endothelial cell growth or accumulation of debris in the lumen. Ragheb discloses that blockages due to restenosis and occlusion occur due to the stent implantation as further found by the Examiner 6Page: Previous 1 2 3 4 5 6 7 8 9 10 NextLast modified: November 3, 2007
