8-K: Puma Biotechnology Loses Key Patent Claim in AstraZeneca Lawsuit Despite Jury Win

Puma Biotechnology, despite a jury win in a patent infringement case against AstraZeneca, has had key patent claims invalidated by the court, leading to an appeal.

Summary

• Puma Biotechnology was involved in a patent infringement lawsuit against AstraZeneca regarding their Tagrisso product, with Wyeth as a co-plaintiff.
• The lawsuit alleged that AstraZeneca's Tagrisso infringed on patents held by Puma and licensed from Pfizer.
• A jury trial in May 2024 found in favor of Wyeth, determining that AstraZeneca infringed on the patents and awarded $107.5 million in damages for past infringement through December 31, 2023.
• A bench trial in June 2024 also ruled in favor of Wyeth on all claims and defenses.
• However, in August 2024, the court granted AstraZeneca's motion for judgment as a matter of law, invalidating key claims of the patents due to lack of enablement and adequate written description.
• Puma disagrees with the court's ruling on invalidity and Wyeth has filed an appeal on September 12, 2024.
