USPTO PatentsView assignee record - 100 granted patents across 53 technology areas, active 2015–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: Y02T (CLIMATE CHANGE MITIGATION TECHNOLOGIES RELATED TO TRANSPORTATION).
The verdict
Perkins holds 100 US patents across 53 technology areas, rank #3,662 of 50,000 tracked assignees.
Perkins Engines Company Limited has been granted 100 US utility patents between 2015 and 2025, placing Perkins Engines Company Limited at rank #3,662 across all assignees tracked by PlainPatent. This portfolio spans 53 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.2 claims per patent with primary concentration in Y02T (CLIMATE CHANGE MITIGATION TECHNOLOGIES RELATED TO TRANSPORTATION). As a Foreign Corporation, Perkins Engines Company Limited is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Perkins sits between Laboratory Corporation OF America Holdings (100 patents, rank #3,658) and Research Institute At Nationwide Children's Hospital (100 patents, rank #3,666) - the closest US assignees by grant volume. The composite Innovation Score of 58.3/100 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 61 grants, compared with 39 in the 2015–2019 window, a +56% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. Perkins Engines Company Limited's 15.2 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 53 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Perkins Engines Company Limited against peers pursuing similar technology classes.

How to use this portfolio
Perkins's 100 grants land it in the top 5% 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.
