CALSONIC KANSEI CORPORATION

CALSONIC KANSEI CORPORATION has been granted 138 US utility patents between 2015 and 2022, placing CALSONIC KANSEI CORPORATION at rank #2,783 across all assignees tracked by PlainPatent. This portfolio spans 80 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.3 claims per patent with primary concentration in B60K (ARRANGEMENT OR MOUNTING OF PROPULSION UNITS OR OF TRANSMISSIONS IN VEHICLES; ARRANGEMENT OR MOUNTING OF PLURAL DIVERSE PRIME-MOVERS IN VEHICLES; AUXILIARY DRIVES FOR VEHICLES; INSTRUMENTATION OR DASHB). As a Foreign Corporation, CALSONIC KANSEI CORPORATION is one of the broader-portfolio assignees in the PatentsView dataset. The composite Innovation Score of 47.2/100 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 19 grants, compared with 119 in the 2015–2019 window — a -84% 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. CALSONIC KANSEI CORPORATION's 8.3 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 80 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark CALSONIC KANSEI CORPORATION against peers pursuing similar technology classes.
