Cascades Ventures Inc.–a descendant of the “original patent troll”–may have reached the end of its campaign against the self-described troll-fighter RPX Corporation and a quintet of tech companies that allegedly orchestrated an illegal boycott of Cascades’s patents.

In a 24-page decision issued on Thursday, U.S. District Judge Yvonne Gonzalez Rogers in Oakland, Calif., dismissed an antirust complaint Cascades brought against RPX, which licenses patents to companies for defensive purposes. Cascades accused RPX of illegally conspiring with five of its members–Dell Inc., HTC Corporation, LG Electronics Inc., Motorola Mobility Inc., and Samsung Electronics Co.–to make it impossible for Cascades to license its patents at a fair price.
