Portfolio overview

HANGZHOU CITY UNIVERSITY has been granted 23 US utility patents between 2023 and 2025, placing HANGZHOU CITY UNIVERSITY at rank #12,957 across all assignees tracked by PlainPatent. This portfolio spans 42 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.3 claims per patent with primary concentration in H05H (PLASMA TECHNIQUE ; PRODUCTION OF ACCELERATED ELECTRICALLY-CHARGED PARTICLES OR OF NEUTRONS; PRODUCTION OR ACCELERATION OF NEUTRAL MOLECULAR OR ATOMIC BEAMS). As a Foreign Corporation, HANGZHOU CITY UNIVERSITY is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 58.9/100 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. Historical data spans 2023 through 2025, with 23 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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. HANGZHOU CITY UNIVERSITY's 8.3 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 42 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark HANGZHOU CITY UNIVERSITY against peers pursuing similar technology classes.

Guides to patent portfolio analysis

How to use this portfolio

Hangzhou's 23 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 - Hangzhou ranks #12,957 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in H05H - see who else leads that technology area. H05H 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.
