Beijing University of Chemical Technology

Q: What technology areas does Beijing University of Chemical Technology focus on?

Beijing University of Chemical Technology's top technology area is B01J (Chemical OR Physical Processes, e.g. Catalysis OR Colloid CHEMISTRY; Their Relevant Apparatus) with 18 patents, ranking #269 of 2,755 assignees active in that subclass. Grants appear in 75 CPC subclasses total.

Q: How is the Beijing University of Chemical Technology patent data sourced?

All patent data comes from USPTO PatentsView, a public research dataset maintained by the United States Patent and Trademark Office covering US granted utility patents from 2015 to 2025.

USPTO PatentsView assignee record - 64 granted patents across 75 technology areas, recorded in grant years 2015–2025. Grant-trend analysis is cross-referenced to USPTO Patent Public Search; it does not measure application filings, current R&D, or legal strength. Primary class: B01J (Chemical OR Physical Processes, e.g. Catalysis OR Colloid CHEMISTRY; Their Relevant Apparatus).

What this shows Beijing's Innovation Score is 52.9/100 (top 9% 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.

Does more volume mean deeper claims for Beijing?

Each dot is one of Beijing’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Beijing’s own 10.5 claims/patent is at or below the 14.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

How Beijing's grant cadence moved

Between 2020–2024, Beijing University of Chemical Technology received 26 grants versus 27 in 2015–2019 (-4% equal-window velocity, above median growth). Across complete PatentsView years, output peaked in 2024 at 8 grants and bottomed in 2023 at 1. Lead class B01J accounts for 28.1% of the portfolio across 75 subclasses. Volume neighbours: Alma Mater STUDIORUM—UNIVERSITÀ DI Bologna (#5,342) and Canopy Growth Corporation (#5,350).

Beijing's three-year grant acceleration

Beijing University of Chemical Technology shows 15 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.
