Patenting trends in circular plasticsAs environmental concerns and legislative pressures mount globally, innovation in plastics recycling and sustainable materials is no longer a niche pursuit; it is a commercial imperative. For UK businesses at the forefront of these developments, the European Patent Office (EPO) provides a valuable resource: Plastics in Transition, a technology platform that provides valuable patent information on the circular plastics economy.

Case Law Review: Board of Appeal Decision T 1741/22Patent applications related to data processing often fall foul of the EPO’s exclusions on “mathematical methods”. Applicants in the MedTech space in particular may find it far easier to protect the hardware in their wearable devices and tools than to protect the software that processes and analyses that data. A recent board of appeal decision T 1741/22 seems to contradict the Guidelines for Examination and previous Board of Appeal decisions. This decision may shed some light on how the EPO may approach these data processing applications in future.
