Rexnord Indus., LLC v. Kappos, No. 11-1434 (Fed. Cir. 2013)
Annotate this CaseIn 2003 Habasit filed an infringement suit against Rexnord, then filed a request for reexamination of the 680 patent, which describes a mechanical conveyor belt that is formed of rows of belt modules interlinked by transverse rods. The interlinked modules form an endless belt that is capable of following a curved path. The spaces between the belt modules are blocked by plastic “webs” so that the spaces are too small to pinch small items such as a finger. The district court stayed the suit pending reexamination. The examiner held all of the claims in the 680 patent unpatentable for anticipation and obviousness. The PTO Board reversed and held the claims patentable. The Federal Circuit affirmed that the claims were not anticipated, but reversed and held that the claimed invention was obvious in view of prior art.
