Portfolio overview

Qingdao University OF Technology has been granted 143 US utility patents between 2019 and 2025, placing Qingdao University OF Technology at rank #2,712 across all assignees tracked by PlainPatent. This portfolio spans 134 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.3 claims per patent with primary concentration in Y02P (CLIMATE CHANGE MITIGATION TECHNOLOGIES IN THE PRODUCTION OR PROCESSING OF GOODS). As a Foreign Corporation, Qingdao University OF Technology is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Qingdao sits between Hutchinson (143 patents, rank #2,708) and Teleflex Medical Incorporated (143 patents, rank #2,716) - the closest US assignees by grant volume. The composite Innovation Score of 67.7/100 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 142 grants, compared with 1 in the 2015–2019 window, a +14100% 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. Qingdao University OF Technology's 9.3 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 Qingdao University OF Technology against peers pursuing similar technology classes.

How to use this portfolio

Qingdao's 143 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 - Qingdao ranks #2,712 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in Y02P - see who else leads that technology area. Y02P 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.
