The verdict
Kanagawa holds 6 US patents across 7 technology areas, rank #41,226 of 50,000 tracked assignees.
Kanagawa Prefectural Hospital Organization has been granted 6 US utility patents between 2016 and 2024, placing Kanagawa Prefectural Hospital Organization at rank #41,226 across all assignees tracked by PlainPatent. This portfolio spans 7 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.0 claims per patent with primary concentration in C07K (PEPTIDES). As a Foreign Corporation, Kanagawa Prefectural Hospital Organization is one of the more focused assignees in the PatentsView dataset. By volume, Kanagawa sits between Kyowa Leather Cloth Co., Ltd. (6 patents, rank #41,222) and Kappler Med + Org Gmbh (6 patents, rank #41,230) - the closest US assignees by grant volume. The composite Innovation Score of 29.3/100 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 1 grants, compared with 5 in the 2015–2019 window, a -80% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. Kanagawa Prefectural Hospital Organization's 11.0 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 7 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Kanagawa Prefectural Hospital Organization against peers pursuing similar technology classes.

How to use this portfolio
Kanagawa's 6 grants land it in the top 70% by Innovation Score, but volume alone doesn't tell you where the strength sits.
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.
