Portfolio overview

Zhejiang University has been granted 888 US utility patents between 2015 and 2025, placing Zhejiang University at rank #506 across all assignees tracked by PlainPatent. This portfolio spans 308 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.4 claims per patent with primary concentration in G06T (IMAGE DATA PROCESSING OR GENERATION, IN GENERAL). As a Foreign Corporation, Zhejiang University is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Zhejiang sits between Nissan North America, Inc. (890 patents, rank #502) and Furukawa Electric Co., Ltd. (883 patents, rank #510) - the closest US assignees by grant volume. The composite Innovation Score of 73.5/100 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 753 grants, compared with 135 in the 2015–2019 window, a +458% 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. Zhejiang University's 8.4 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a diversified footprint across 100+ CPC subclasses spreads risk across many technology fronts. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Zhejiang University against peers pursuing similar technology classes.

How to use this portfolio

Zhejiang's 888 grants land it in the top 0.1% 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 - Zhejiang ranks #506 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in G06T - see who else leads that technology area. G06T 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.
