False Marking Plaintiff Patent Group, LLC Becomes Patent Infringement Plaintiff

Patent Group, LLC filed suit today against at least seven defendants (as of the time of this writing) in the Eastern District of Texas, alleging infringement of U.S. Patent No. 6,603,490, which it asserts it owns by assignment. As some may recall, Patent Group, LLC was first known as a prolific false marking plaintiff, having filed over 175 false marking cases of the close to 1000 such cases filed since the beginning of 2010. Settlements occurred in the majority of Patent Group, LLC's false marking cases, totaling over $2.8 million, half of which Patent Group, LLC itself kept under the pre-AIA version of the false marking statute. Today's filings are the first affirmative patent infringement cases filed by Patent Group, LLC.
