Portfolio overview

Hitachi Medical Corporation has been granted 116 US utility patents between 2015 and 2016, placing Hitachi Medical Corporation at rank #3,226 across all assignees tracked by PlainPatent. This portfolio spans 31 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.0 claims per patent with primary concentration in A61B (DIAGNOSIS; SURGERY; IDENTIFICATION). As a Foreign Corporation, Hitachi Medical Corporation is one of the more focused assignees in the PatentsView dataset. By volume, Hitachi sits between BOOZ Allen Hamilton Inc. (116 patents, rank #3,222) and KOA Corporation (116 patents, rank #3,230) - the closest US assignees by grant volume. The composite Innovation Score of 43.3/100 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 0 grants, compared with 116 in the 2015–2019 window, a -100% 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. Hitachi Medical Corporation's 12.0 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 31 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Hitachi Medical Corporation 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.
