Company patents

Waseda University

Waseda University's patent strategy reveals a surprising recent shift, with significant declines in several key areas. While categories like Catalysts & Reactors, Batteries & Fuel Cells, and Medical Diagnostics & Surgery each represent 8.2% or more of their portfolio, all have seen a 100.0% year-over-year decline in patenting activity so far in 2026, indicating a potential reprioritization away from these established research areas.
