Portfolio overview

University Of South China has been granted 6 US utility patents between 2022 and 2025, placing University Of South China at rank #43,837 across all assignees tracked by PlainPatent. This portfolio spans 13 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.3 claims per patent with primary concentration in G01N (INVESTIGATING OR ANALYSING MATERIALS BY DETERMINING THEIR CHEMICAL OR PHYSICAL PROPERTIES). As a Foreign Corporation, University Of South China is one of the more focused assignees in the PatentsView dataset. By volume, University sits between University Of Connecticut Health Center (6 patents, rank #43,833) and University Of The Witwatersrand (6 patents, rank #43,841) - the closest US assignees by grant volume. The composite Innovation Score of 46.9/100 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 2022 through 2025, with 6 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. University Of South China's 12.3 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 13 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark University Of South China against peers pursuing similar technology classes.

How to use this portfolio

University's 6 grants land it in the top 20% 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 - University ranks #43,837 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.
