ParkerVision, Inc. v. NXP Semiconductors N.V. et al.

The patent infringement litigation ParkerVision, Inc. v. NXP Semiconductors N.V. et al. (6:23-cv-00389-ADA) involves ParkerVision, Inc. as the Plaintiff and NXP Semiconductors N.V., NXP B.V., and NXP USA, Inc. d/b/a NXP Semiconductors USA, Inc. as the Defendants. ParkerVision is a Jacksonville, Florida-based technology licensing company that designs, develops, and markets proprietary radio frequency (RF) technologies and integrated circuits for wireless communication products, holding a substantial patent portfolio and focusing on intellectual property enforcement through licensing and litigation. NXP Semiconductors is a Dutch semiconductor manufacturing and design company headquartered in Eindhoven, Netherlands, providing high-performance mixed-signal and standard product solutions for automotive, industrial & IoT, mobile, and communication infrastructure markets.

The lawsuit, filed on May 19, 2023, accuses NXP of infringing United States Patent No. 7,483,686 ("the '686 Patent"), along with two other patents, 7,865,177 and 9,118,528. The '686 Patent generally relates to multi-mode communications devices and, more particularly, to such devices implemented using universal frequency translation technology, providing a universal platform module (UPM) for signal reception, transmission, and/or processing. While the specific accused products are not explicitly detailed in the immediately available search results, ParkerVision's lawsuits generally target providers of mobile handsets, smart televisions, and other WiFi products, and their chip suppliers, for infringement of its RF patents.

The case is being heard in the United States District Court for the Western District of Texas, Waco Division, before Judge Alan D. Albright. This venue is notable because Judge Albright, a former patent litigator, actively sought to attract patent cases to his courtroom, leading to a surge in patent litigation filings in the Waco Division, particularly from non-practicing entities (NPEs). While the Western District of Texas had been a leading venue, case assignment reforms implemented in 2024 have impacted the concentration of cases before Judge Albright, though he remains a significant figure in patent litigation. The case is currently stayed pending Inter Partes Reviews (IPRs) concerning the '177 and '528 patents, which NXP joined after Texas Instruments filed initial petitions, with the Patent Trial and Appeal Board (PTAB) expected to issue final written decisions by November 26, 2025. The existing case summary states the trial date is rescheduled for February 9, 2026. This IPR linkage and the strategic choice of venue in the Western District of Texas highlight the complex procedural landscape and common tactics in modern patent litigation.

The patent infringement litigation ParkerVision, Inc. v. NXP Semiconductors N.V. et al. (6:23-cv-00389-ADA) has seen several key legal developments since its filing. The case is currently stayed pending the outcome of parallel Inter Partes Review (IPR) proceedings concerning two of the three asserted patents.

Here's a chronological summary of the key legal developments:

• Filing & Initial Pleadings (2023-05-19): ParkerVision, Inc. filed the complaint on May 19, 2023, accusing NXP Semiconductors N.V., NXP B.V., and NXP USA, Inc. of infringing U.S. Patent Nos. 7,483,686 ('686 Patent), 7,865,177 ('177 Patent), and 9,118,528 ('528 Patent). Details regarding NXP's answer and any counterclaims are not explicitly available in the provided sources.

• Pre-trial Motions of Substance:

  • Motion to Stay Pending IPR (Filed 2025): NXP filed a motion to stay the case pending the outcome of two Inter Partes Reviews concerning the '177 and '528 patents. ParkerVision opposed this motion.
  • Order Granting Stay (2025-05-27): The Court granted NXP's Motion to Stay Pending Inter Partes Review on May 27, 2025. The stay is in effect until the Patent Trial and Appeal Board (PTAB) issues its Final Written Decisions (FWDs) for the IPRs, which are expected by November 26, 2025.

• Claim Construction (Markman) Outcomes:

  • Markman Hearing (2024-06-14): A Special Master appointed in the case held a Markman hearing on June 14, 2024, to construe disputed claim terms.
  • Report & Recommendation and Adoption (2024): The Special Master subsequently issued a report and recommendation regarding claim construction (ECF No. 45), which the Court adopted (ECF No. 65). The '686 patent was part of this claim construction process, with ParkerVision previously seeking reconsideration of certain constructions related to it and the '528 patent, which the Court had consistently maintained in prior litigations. All disputed terms were reported as "finally construed."

• Discovery Milestones:

  • Discovery Hearing (2025-04-03): The Court held a discovery hearing on April 3, 2025. ParkerVision's counsel failed to appear, and the Court issued several orders related to document production and depositions, including requirements for ParkerVision to provide descriptions of recently produced documents, a list of search terms used, and a certification of complete document production.
  • Fact Discovery Close (Scheduled): Fact discovery was scheduled to close approximately one month after the May 27, 2025, order granting the stay. The Court noted that NXP had been the only party to notice or take any party depositions, and multiple fact depositions remained to be taken.

• Trial Events, Verdict, and Post-trial Motions:

  • There have been no trial events, verdict, or post-trial motions to date as the case is currently stayed, and the trial is scheduled for February 9, 2026.

• Final Disposition or Present Posture:

  • The case is currently stayed as of May 27, 2025, pending the PTAB's Final Written Decisions for the IPRs on the '177 and '528 patents. An amended scheduling order had previously rescheduled the trial date from August 18, 2025, to February 9, 2026.

• Parallel PTAB IPR/PGR Proceedings:

  • IPR Filings by Texas Instruments (2024-05-18): Texas Instruments, a defendant in a related lawsuit by ParkerVision, filed IPR petitions on the '177 Patent and '528 Patent on May 18, 2024.
  • IPR Filings by NXP (2024-06-20): NXP filed "copycat" IPR petitions and requested to join Texas Instruments' IPR proceedings on June 20, 2024.
  • Institution of IPRs (2024-11-26 and 2024-12-19): The PTAB granted Texas Instruments' petitions on November 26, 2024. The PTAB subsequently granted NXP's petitions and requests for joinder to the TI proceedings on December 19, 2024.
  • Effect on Litigation: The pendency of these IPRs led to the district court granting NXP's motion to stay the infringement litigation, with FWDs expected by November 26, 2025. It is important to note that the '686 patent, one of the patents at issue in the litigation, is not among the patents subject to these IPR proceedings.
