1. Case Against Google

• Plaintiff(s): Personalized Media Communications, LLC
• Defendant(s): Google LLC
• Jurisdiction: U.S. District Court for the Eastern District of Texas (Marshall Division)
• Case Number: 2:19-cv-00090
• Filing Date: March 15, 2019
• Outcome or Current Status: This case has a complex and notable history.
  • March 2021: Following a jury trial, the jury found that Google's services, including YouTube, infringed on the patent. The jury awarded PMC $308.5 million in damages.
  • August 2021: In a rare move, Judge J. Rodney Gilstrap overturned the jury's verdict and ruled in favor of Google. The judge found that PMC was barred from enforcing the patent against Google due to the doctrine of "prosecution laches," concluding that PMC had engaged in an unreasonable and inexcusable delay in prosecuting its patent applications to the prejudice of Google.
  • May 2023: PMC appealed the decision to the U.S. Court of Appeals for the Federal Circuit (CAFC). The CAFC reversed Judge Gilstrap's ruling, finding that the district court had erred in its application of the prosecution laches defense. The Federal Circuit reinstated the original $308.5 million jury verdict against Google.
  • Current Status: The case was remanded back to the district court for further proceedings consistent with the appellate ruling. Google's subsequent petition for an en banc rehearing by the full Federal Circuit was denied. The case is effectively active again at the district court level, with the verdict reinstated, pending any further appeals by Google to the Supreme Court or a potential settlement between the parties.

2. Case Against Apple

While part of a broader campaign, the litigation against Apple involving this patent family had a very different outcome, primarily driven by proceedings at the Patent Office.

• Plaintiff(s): Personalized Media Communications, LLC
• Defendant(s): Apple Inc.
• Jurisdiction: U.S. District Court for the Eastern District of Texas
• Case Number: 2:15-cv-01366
• Filing Date: August 14, 2015
• Outcome or Current Status: Terminated in Apple's favor.
  • In response to the lawsuit, Apple challenged the validity of numerous PMC patents, including claims of U.S. Patent 8,069,073, by filing petitions for inter partes review (IPR) with the Patent Trial and Appeal Board (PTAB).
  • The PTAB instituted reviews and ultimately found many of the asserted claims of PMC's patents, including those from the '073 patent, to be unpatentable.
  • PMC appealed the PTAB's decisions to the U.S. Court of Appeals for the Federal Circuit.
  • In a series of decisions, most notably in 2021, the Federal Circuit affirmed the PTAB's findings, invalidating the relevant claims of the patents asserted against Apple.
  • Outcome: Due to the successful invalidation of the patent claims at the PTAB, PMC's infringement case against Apple was effectively ended. The case was ultimately dismissed.
