MPHJ Technology Investments, which has been aggressively attempting to enforce a patent on networked scanning technology, has sued the Federal Trade Commission over what it called unconstitutional threats about its enforcement tactics.

Meanwhile, MPHJ marked a number of milestones in a busy litigation portfolio. On Tuesday, New York Attorney General Eric Schneiderman announced a settlement concerning the outfit’s patent enforcement activities. And MPHJ scored at least a temporary victory in Nebraska, where a federal judge imposed a preliminary injunction against Attorney General Jon Bruning’s attempt to block patent enforcement efforts by MPHJ’s law firm, Farney Daniels of Georgetown, Texas.
