Portfolio overview

Funai Electric Co., Ltd. has been granted 541 US utility patents between 2015 and 2024, placing Funai Electric Co., Ltd. at rank #843 across all assignees tracked by PlainPatent. This portfolio spans 121 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.5 claims per patent with primary concentration in B41J (TYPEWRITERS; SELECTIVE PRINTING MECHANISMS, i.e. MECHANISMS PRINTING OTHERWISE THAN FROM A FORME; CORRECTION OF TYPOGRAPHICAL ERRORS). As a Foreign Corporation, Funai Electric Co., Ltd. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Funai sits between Digimarc Corporation (543 patents, rank #839) and Citic Dicastal Co., Ltd. (538 patents, rank #847) - the closest US assignees by grant volume. The composite Innovation Score of 60.6/100 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 173 grants, compared with 368 in the 2015–2019 window, a -53% 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. Funai Electric Co., Ltd.'s 15.5 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a diversified footprint across 100+ CPC subclasses spreads risk across many technology fronts. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Funai Electric Co., Ltd. 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.
