Portfolio overview

National Hospital Organization has been granted 10 US utility patents between 2017 and 2022, placing National Hospital Organization at rank #26,925 across all assignees tracked by PlainPatent. This portfolio spans 11 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.4 claims per patent with primary concentration in A61P (SPECIFIC THERAPEUTIC ACTIVITY OF CHEMICAL COMPOUNDS OR MEDICINAL PREPARATIONS). As a Foreign Corporation, National Hospital Organization is one of the more focused assignees in the PatentsView dataset. By volume, National sits between Nantong Institute OF Nanjing University OF Posts AND Telecommunications Co., Ltd. (10 patents, rank #26,921) and NEW Kailung GEAR Co., Ltd (10 patents, rank #26,929) - the closest US assignees by grant volume. The composite Innovation Score of 26.2/100 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 2 grants, compared with 8 in the 2015–2019 window, a -75% 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. National Hospital Organization's 8.4 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 11 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark National Hospital Organization 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.
