Portfolio overview
China Medical University has been granted 67 US utility patents between 2015 and 2025, placing China Medical University at rank #5,149 across all assignees tracked by PlainPatent. This portfolio spans 30 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.5 claims per patent with primary concentration in A61P (SPECIFIC THERAPEUTIC ACTIVITY OF CHEMICAL COMPOUNDS OR MEDICINAL PREPARATIONS). As a Foreign Corporation, China Medical University is one of the more focused assignees in the PatentsView dataset. By volume, China sits between Cambridge Mechatronics Limited (67 patents, rank #5,145) and Entrust Corporation (67 patents, rank #5,153) - the closest US assignees by grant volume. The composite Innovation Score of 45.0/100 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 38 grants, compared with 29 in the 2015–2019 window, a +31% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. China Medical University's 8.5 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 30 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark China Medical University against peers pursuing similar technology classes.

How to use this portfolio
China's 67 grants land it in the top 24% 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 - China ranks #5,149 of 50,000. Top 50 holders
- Most of this portfolio concentrates in A61P - see who else leads that technology area. A61P 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.
