In March 2025, ParkerVision, Inc. faced a legal setback as the U.S. Supreme Court denied its prior attempt to challenge adverse Patent Trial and Appeal Board (PTAB) rulings. These rulings were related to patents asserted against TCL Industries Holdings Co., Ltd. and LG Electronics Inc.
The Supreme Court's denial effectively closes that avenue of appeal for ParkerVision regarding these specific patent validity challenges. This outcome means the company cannot further contest the PTAB's decisions through the Supreme Court.
This development impacts ParkerVision's broader patent enforcement strategy, as it limits the company's options for monetizing its intellectual property in these particular cases. The company's business model is entirely dependent on successful patent litigation and licensing.
