What changed

The EPO published electro-optical component patent EP4548153A1 filed by the University of Salford (inventor: Mark Hughes), covering photonic integrated circuits with applications in quantum computing systems. The patent specifies IPC classifications including G02F 1/00 (electro-optical devices), G06N 10/40 (quantum computing), and B82Y 20/00 (nanophotonics).

This is a patent publication notice rather than a regulatory rule. No compliance actions, deadlines, or penalties apply. Technology companies developing photonic integrated circuits or quantum computing hardware may wish to conduct freedom-to-operate analyses to assess potential infringement risks.
