After making headway in a patent infringement lawsuit targeting Samsung Electronics Co. and HTC Corp., Cascades Computer Innovation LLC, a descendent of the “original patent troll,” is looking to reboot its related antitrust case against the technology companies and codefendant RPX Corp.

Cascades and its lawyers at Niro, Haller & Niro, including senior partner Raymond Niro, last week urged U.S. District Judge Yvonne Gonzalez Rogers in Oakland, Calif., to lift a stay in their antitrust lawsuit challenging RPX's business model. RPX, which bills itself as a “defensive patent aggregator” that shields members from nonpracticing entities, or “trolls,” offers companies access to its portfolio of patents for a fee.

Cascades was founded by onetime Jenner & Block partner Anthony Brown, whose prior business venture, TechSearch, famously inspired Intel's former general counsel to coin the phrase “patent troll.” The company's antitrust suit, filed in 2012, alleges that RPX and several Android smartphone makers illegally boycotted licensing offers on a portfolio of more than 35 Cascades patents.
