In re Adler
July 18, 2013
Panel: Prost, Reyna and Wallach. Opinion by Wallach
Summary
The Examiner rejected all of the pending claims under 35 U.S.C. §103 as obvious over several prior art references, including International Patent Publication WO 00/22975 (“Meron”) in view of Masaru Hirata et al., Study of New Prognostic Factors of Esophageal Variceal Rupture By Use of Image Processing With a Video Endoscope, 116 Surgery 8–16 (1994) (“Hirata”).
The Board of Patent Appeals and Interferences (“the Board”) affirmed the Examiner’s rejection of all pending claims of U.S. Patent Application No. 10/097,096 (the ‘096 application) under 35 U.S.C. §103 as being obvious over a combination of prior art references. Adler appealed the Board’s decision to the Court of Appeals for the Federal Circuit (CAFC). The CAFC affirms holding that the Board did not err in rejecting the pending claims as obvious and did not rely on new grounds for rejection.
