How Asahi's grant cadence moved

Between 2020–2024, Asahi Kasei Chemicals Corporation received 6 grants versus 163 in 2015–2019 (-96% equal-window velocity, below median growth). Across complete PatentsView years, output peaked in 2015 at 54 grants and bottomed in 2022 at 1. Lead class C07C accounts for 30.8% of the portfolio across 78 subclasses. Volume neighbours: Sumitomo Bakelite Co., Ltd. (#2,302) and Danieli & C. Officine Meccaniche S.P.A. (#2,310).

Asahi's three-year grant acceleration

Asahi Kasei Chemicals Corporation shows 1 grants in 2022–2024 against only 14 in 2019–2021. That prior window is too thin for a growth multiple (rename and spin-out assignees look artificially high when the baseline is near zero), so PlainPatent withholds a ranked acceleration claim here.
