Finisar Corp. sued XM and Sirius for allegedly infringing a patent for an information-transmission system, the AP reported.
The firm makes fiber optic systems for telecommunications networks. It filed in April in U.S. District Court for the Eastern District of Texas, according to a regulatory filing this week. It seeks damages payments and an injunction to stop infringement.
“The court assigned to the case the same judge who ruled in favor of Finisar when it sued satellite television provider DirecTV Group Inc. for infringing the same patent,” AP reported. “Finisar received damages payments, but DirecTV was allowed to continue using the technology in return for licensing payments. The patent covers the transmission of large packets of data using relatively little capacity.”
