A patent holding company will get another chance to press its infringement allegations against T-Mobile USA Inc.
The U.S. Court of Appeals for the Federal Circuit Sept. 4 revived Intellectual Ventures I LLC’s lawsuit against the mobile carrier, relating to a patent for allocating data network resources.
The district court ruled that T-Mobile didn’t infringe the patent and threw out that part of the lawsuit. But the appeals court said the lower court misinterpreted a term in the patent claim, leading to the non-infringement ruling.
The case will go back to the district court for further proceedings using the correct interpretation of the patent claim.
The Federal Circuit affirmed the district court’s ruling that another claim in the patent was invalid because it’s indefinite.
The case is Intellectual Ventures I LLC v. T-Mobile USA, Inc., Fed. Cir., No. 17-2434, 9/4/18.
