Portfolio overview

CANON DENSHI KABUSHIKI KAISHA has been granted 73 US utility patents between 2015 and 2025, placing CANON DENSHI KABUSHIKI KAISHA at rank #4,755 across all assignees tracked by PlainPatent. This portfolio spans 33 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.1 claims per patent with primary concentration in G03B (APPARATUS OR ARRANGEMENTS FOR TAKING PHOTOGRAPHS OR FOR PROJECTING OR VIEWING THEM; APPARATUS OR ARRANGEMENTS EMPLOYING ANALOGOUS TECHNIQUES USING WAVES OTHER THAN OPTICAL WAVES; ACCESSORIES THEREFOR). As a Foreign Corporation, CANON DENSHI KABUSHIKI KAISHA is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 44.0/100 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 25 grants, compared with 48 in the 2015–2019 window — a -48% 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 DENSHI KABUSHIKI KAISHA's 11.1 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 33 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark CANON DENSHI KABUSHIKI KAISHA against peers pursuing similar technology classes.
