Portfolio overview

Anhui University OF Science AND Technology has been granted 34 US utility patents between 2017 and 2025, placing Anhui University OF Science AND Technology at rank #9,179 across all assignees tracked by PlainPatent. This portfolio spans 41 distinct Cooperative Patent Classification (CPC) subclasses, averaging 7.5 claims per patent with primary concentration in G01N (INVESTIGATING OR ANALYSING MATERIALS BY DETERMINING THEIR CHEMICAL OR PHYSICAL PROPERTIES). As a Foreign Corporation, Anhui University OF Science AND Technology is one of the more focused assignees in the PatentsView dataset. By volume, Anhui sits between ALI S.p.a.—carpigiani Group (34 patents, rank #9,175) and ASM America, Inc. (34 patents, rank #9,183) - the closest US assignees by grant volume. The composite Innovation Score of 59.4/100 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 32 grants, compared with 2 in the 2015–2019 window, a +1500% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. Anhui University OF Science AND Technology's 7.5 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 41 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Anhui University OF Science AND Technology against peers pursuing similar technology classes.

How to use this portfolio

Anhui's 34 grants land it in the top 4% 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 - Anhui ranks #9,179 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in G01N - see who else leads that technology area. G01N 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.
