Portfolio overview

Beijing Research Institute OF Chemical Industry, China Petroleum & Chemical Corporation has been granted 83 US utility patents between 2015 and 2025, placing Beijing Research Institute OF Chemical Industry, China Petroleum & Chemical Corporation at rank #4,277 across all assignees tracked by PlainPatent. This portfolio spans 50 distinct Cooperative Patent Classification (CPC) subclasses, averaging 26.5 claims per patent with primary concentration in C08F (MACROMOLECULAR COMPOUNDS OBTAINED BY REACTIONS ONLY INVOLVING CARBON-TO-CARBON UNSATURATED BONDS). As a Foreign Corporation, Beijing Research Institute OF Chemical Industry, China Petroleum & Chemical Corporation is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Beijing sits between Acumed Llc (83 patents, rank #4,273) and Change Healthcare Holdings, Llc (83 patents, rank #4,281) - the closest US assignees by grant volume. The composite Innovation Score of 65.3/100 blends portfolio volume, filing velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.

Filing cadence tells the strategic story. Between 2020 and 2025 the company received 39 grants, compared with 44 in the 2015–2019 window, a -11% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. The Foreign Corporation classification further shapes interpretation, since corporate, government, and individual filers pursue patents for materially different reasons.

Claim depth and technology breadth together indicate competitive posture. Beijing Research Institute OF Chemical Industry, China Petroleum & Chemical Corporation's 26.5 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while a multi-domain presence across 50 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Beijing Research Institute OF Chemical Industry, China Petroleum & Chemical Corporation against peers pursuing similar technology classes.

How to use this portfolio

Beijing's 83 grants land it in the top 1% by Innovation Score, but volume alone doesn't tell you where the strength sits.

  • Read that count against the largest US assignees before treating it as dominance - Beijing ranks #4,277 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in C08F - see who else leads that technology area. C08F leaders
  • Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works

Patent counts and the Innovation Score measure patenting activity, not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
