Short Summary
Wabtec has filed an IPR petition challenging Railware’s RE 47835 patent covering railway block‑and‑unblock code systems. The petition asserts obviousness over the FRA‑Report and several secret‑code references.
Detailed Summary
In IPR2026-00134, Westinghouse Air Brake Technologies Corporation (Wabtec) petitions the PTAB to cancel claims 1‑7, 9‑16, and 18‑41 of Railware’s reissued patent RE 47835, which claims a centralized railway traffic control system that blocks track sections and uses a removal or secret release code transmitted to a worker’s device. The petitioner contends that the claimed inventions are obvious in view of the Federal Railroad Administration’s FRA‑Report combined with secret‑code implementations disclosed in the Kruijswijk, Macey, Schmitz, and Byford references. The petition also argues there is no basis for discretionary denial and seeks institution of the review.
