Portfolio overview

GUANDONG OCEAN UNIVERSITY has been granted 40 US utility patents between 2019 and 2025, placing GUANDONG OCEAN UNIVERSITY at rank #8,036 across all assignees tracked by PlainPatent. This portfolio spans 56 distinct Cooperative Patent Classification (CPC) subclasses, averaging 6.8 claims per patent with primary concentration in Y02A (TECHNOLOGIES FOR ADAPTATION TO CLIMATE CHANGE). As a Foreign Corporation, GUANDONG OCEAN UNIVERSITY is one of the broader-portfolio assignees in the PatentsView dataset. The composite Innovation Score of 61.9/100 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. Between 2020 and 2025 the company received 39 grants, compared with 1 in the 2015–2019 window — a +3800% 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. GUANDONG OCEAN UNIVERSITY's 6.8 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 56 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark GUANDONG OCEAN UNIVERSITY against peers pursuing similar technology classes.

How to use this portfolio

Guandong's 40 grants land it in the top 3% 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 — Guandong ranks #8,036 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in Y02A — see who else leads that technology area. Y02A 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.
