Short Summary
GE Healthcare petitions to invalidate Johns Hopkins' U.S. Patent 12,115,233 covering FAP‑targeting radiopharmaceuticals, asserting obviousness, lack of written description, and lack of enablement.
Detailed Summary
In a petition for post‑grant review (PGR2025‑00059), GE Healthcare Ltd. challenges U.S. Patent No. 12,115,233 owned by Johns Hopkins University. The petitioner contends that claims 1‑4 are obvious in view of US‑633 combined with Meletta and Jansen, and also in view of US‑121 together with Jansen. Additionally, the petition argues that the specification fails to provide a sufficient written description and does not enable the claimed breadth of low‑molecular‑weight FAP‑targeting compounds, which number in the billions. The Board is urged to institute trial and cancel the claims.
Practitioner Note
This case demonstrates the evidentiary and procedural standards applied in patent matters before local courts. Understanding the court's reasoning in GE Healthcare Ltd. et al. vs The Johns Hopkins University et al. is valuable context for structuring arguments or assessing risk in similar proceedings.
