Portfolio overview

Canon Anelva Corporation has been granted 185 US utility patents between 2015 and 2025, placing Canon Anelva Corporation at rank #2,127 across all assignees tracked by PlainPatent. This portfolio spans 40 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.2 claims per patent with primary concentration in H01J (ELECTRIC DISCHARGE TUBES OR DISCHARGE LAMPS). As a Foreign Corporation, Canon Anelva Corporation is one of the more focused assignees in the PatentsView dataset. By volume, Canon sits between The Chamberlain Group Llc (186 patents, rank #2,123) and Ossur Iceland EHF (185 patents, rank #2,131) - the closest US assignees by grant volume. The composite Innovation Score of 53.1/100 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 68 grants, compared with 117 in the 2015–2019 window, a -42% 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. Canon Anelva Corporation's 11.2 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 40 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Canon Anelva 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.
