ParkerVision receives ‘favorable’ Markman rulings in infringement actions

ParkerVision announced that the United States District Court for the Western District of Texas issued its Markman, or claim construction, rulings in ParkerVision’s patent infringement actions against MediaTek Inc. and MediaTek USA Inc. and Realtek Semiconductor Corp. The Court’s claim constructions are largely favorable to ParkerVision. The Court held back-to-back Markman hearings on Friday, January 26, 2024, for the MediaTek and Realtek actions. Consistent with its standard practice, the Court issued preliminary rulings on the disputed claim constructions in advance of the Markman hearings. The Markman hearings were then held to allow the parties to present arguments with regard to any of the Court’s preliminary rulings that they wished the Court to reconsider and/or fine-tune. In ParkerVision v. MediaTek, the Court adopted ParkerVision’s proposed claim constructions for 13 of 16 disputed terms while adopting two proposed terms for MediaTek, and one term the Court construed on its own. In ParkerVision v. Realtek, the Court adopted ParkerVision’s proposed claim constructions for nine of 10 disputed terms, with the one remaining term being a combination of the proposals from both parties. These MediaTek and Realtek infringement actions were initially filed in November 2022 and allege infringement against both parties of the same four ParkerVision patents. Both cases are scheduled for jury trial in December 2024. The Company has inter partes review actions pending against one of the patents. In 2023, ParkerVision filed two additional infringement cases against MediaTek and one new infringement case against Realtek alleging infringement of different ParkerVision patents.
