What this shows Beijing's Innovation Score is 65.3/100 (top 1% of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

How Beijing's grant cadence moved

Between 2020–2024, Beijing Research Institute OF Chemical Industry, China Petroleum & Chemical Corporation received 31 grants versus 44 in 2015–2019 (-30% equal-window velocity, below median growth). Across complete PatentsView years, output peaked in 2016 at 15 grants and bottomed in 2019 at 4. Lead class C08F accounts for 57.8% of the portfolio across 50 subclasses. Volume neighbours: Acumed LLC (#4,273) and Change Healthcare Holdings, LLC (#4,281).

Beijing's three-year grant acceleration

Beijing Research Institute OF Chemical Industry, China Petroleum & Chemical Corporation shows 21 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.
