Portfolio overview

HOYA Corporation has been granted 718 US utility patents between 2015 and 2025, placing HOYA Corporation at rank #614 across all assignees tracked by PlainPatent. This portfolio spans 82 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.4 claims per patent with primary concentration in A61B (DIAGNOSIS; SURGERY; IDENTIFICATION). As a Foreign Corporation, HOYA Corporation is one of the broader-portfolio assignees in the PatentsView dataset. By volume, HOYA sits between Exxonmobil Research AND Engineering Company (724 patents, rank #610) and FG Innovation Company Limited (714 patents, rank #618) - the closest US assignees by grant volume. The composite Innovation Score of 63.0/100 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 344 grants, compared with 374 in the 2015–2019 window, a -8% 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. HOYA Corporation's 13.4 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 82 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark HOYA 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.
