Portfolio overview

Denso Corporation has been granted 9,480 US utility patents between 2015 and 2025, placing Denso Corporation at rank #39 across all assignees tracked by PlainPatent. This portfolio spans 307 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.5 claims per patent with primary concentration in B60W (CONJOINT CONTROL OF VEHICLE SUB-UNITS OF DIFFERENT TYPE OR DIFFERENT FUNCTION; CONTROL SYSTEMS SPECIALLY ADAPTED FOR HYBRID VEHICLES; ROAD VEHICLE DRIVE CONTROL SYSTEMS FOR PURPOSES NOT RELATED TO THE). As a Foreign Corporation, Denso Corporation is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Denso sits between NEC Corporation (9,672 patents, rank #35) and Sharp Kabushiki Kaisha (8,041 patents, rank #43) - the closest US assignees by grant volume. The composite Innovation Score of 68.0/100 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 4,895 grants, compared with 4,585 in the 2015–2019 window, a +7% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. Denso Corporation's 10.5 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, 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 Denso Corporation against peers pursuing similar technology classes.
