Detailed Summary

Godbersen-Smith Construction Company d/b/a GOMACO Corporation has filed a Petition challenging U.S. Patent No. 11,535,318 on grounds of obviousness (35 U.S.C. § 103). The Petitioner asserts that claims 1 through 8 are rendered unpatentable by combining prior art references CIII and Rio, with additional combinations involving Smolders for specific claims. GOMACO argues that the combination would have been predictable to a Person of Ordinary Skill in the Art (POSITA) seeking to eliminate manual adjustments during slipform paver operations. Furthermore, Petitioner raises issues regarding discretionary denial under § 325(d), stating the examiner failed to consider these relevant references during prosecution.
