SAN FRANCISCO — IP litigator Matthew Powers has taken aim at Microsoft Corp., a company that counted him among its go-to defenders before he crossed over to plaintiffs work.
Represented by Powers’ firm, Tensegrity Law Group, IPLearn-Focus sued Microsoft in U.S. District Court for the Northern District of California on Friday for patent infringement. The Mountain View–based company claims that Microsoft’s Xbox products infringe three of its patents for aspects of systems with detached sensors. Microsoft did not respond to IPLearn-Focus’s offer to discuss a licensing partnership, according to the complaint.
