Portfolio overview

Nippon Medical School Foundation has been granted 11 US utility patents between 2015 and 2025, placing Nippon Medical School Foundation at rank #24,861 across all assignees tracked by PlainPatent. This portfolio spans 13 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.0 claims per patent with primary concentration in A61K (PREPARATIONS FOR MEDICAL, DENTAL OR TOILETRY PURPOSES). As a Foreign Corporation, Nippon Medical School Foundation is one of the more focused assignees in the PatentsView dataset. By volume, Nippon sits between Ningbo Royalux Lighting Co., Ltd. (11 patents, rank #24,857) and Noramco, Llc (11 patents, rank #24,865) - the closest US assignees by grant volume. The composite Innovation Score of 40.7/100 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 6 grants, compared with 5 in the 2015–2019 window, a +20% 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. Nippon Medical School Foundation's 10.0 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 13 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Nippon Medical School Foundation against peers pursuing similar technology classes.

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.
