Belden Inc. v. Berk-Tek LLC, No. 14-1575 (Fed. Cir. 2015)
Annotate this CaseBelden and Berk-Tek compete in making and selling telecommunications cable and cabling systems. Belden’s 503 patent, issued in 2000, discloses a method of making a cable by passing a core and conducting wires through one or more dies, bunching the wires into grooves on the core, twisting the bunch to close the cable, and jacketing the entire assembly. On Berk-Tek’s motion, the PTO instituted inter partes review and rejected claims 1–4 of the 503 patent for obviousness, while confirming claims 5 and 6. The Federal Circuit affirmed rejection of claims 1–4, reversed at to claims 5 and 6, and rejected Belden’s contention that the Board denied it procedural rights.
