Modem Expert in Chip Technology

Case Description:

A modem expert was needed for an infringement dispute. The plaintiff claimed infringement of several of its patents. The defendant was a developer of digital signal processor (DSP) chips specializing in communications chip technology for network equipment. The patents involved universal modems with preloaded telephone system parameters of multiple countries and the functionality of host signal processing modems in regard to software emulation of UART (universal asynchronous receiver or transmitter).

IMS ExpertServices was asked to locate a team of modem experts experienced in product development or testing. The experts needed to have experience in reading patents and understand the chip technology of these patents.
