Across all tracked assignees
USPTO PatentsView assignee record - 9 granted patents across 7 technology areas, active 2021–2024. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: F02D (CONTROLLING COMBUSTION ENGINES).
The verdict
Denso holds 9 US patents across 7 technology areas, rank #28,537 of 50,000 tracked assignees.
Denso Daishin Corporation has been granted 9 US utility patents between 2021 and 2024, placing Denso Daishin Corporation at rank #28,537 across all assignees tracked by PlainPatent. This portfolio spans 7 distinct Cooperative Patent Classification (CPC) subclasses, averaging 7.7 claims per patent with primary concentration in F02D (CONTROLLING COMBUSTION ENGINES). As a Foreign Corporation, Denso Daishin Corporation is one of the more focused assignees in the PatentsView dataset. By volume, Denso sits between DELK, Inc. (9 patents, rank #28,533) and Deviceeng Co., Ltd. (9 patents, rank #28,541) - the closest US assignees by grant volume. The composite Innovation Score of 41.9/100 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. Historical data spans 2021 through 2024, with 9 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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 Daishin Corporation's 7.7 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 7 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Denso Daishin Corporation against peers pursuing similar technology classes.

How to use this portfolio
Denso's 9 grants land it in the top 32% by Innovation Score, but volume alone doesn't tell you where the strength sits.
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.
