In IPR 2018-01472, brought by Apple Inc., HTC Corporation, HTC America, Inc., and ZTE (USA) Inc. (Apple), the Patent Trial and Appeal Board (PTAB) last week determined all challenged claims of INVT SPE LLC’s (INVT) Patent No. 6,466,563 to be unpatentable as obvious. The ‘563 patent is titled “CDMA [Code Division Multiple Access] Mobile Station and CDMA Transmission Method” and was issued on October 15, 2002. The patent describes an addition of burst data to the end of a transmission “allow[ing] synchronization with the base station apparatus to be maintained,” thus “making it possible to restart communication immediately.” The transmission interval control circuit also “controls the transmission interval of burst data to N times one slot (N: a natural number) at the end of transmission” to conserve power consumption.
