The verdict
Cambridge holds 67 US patents across 24 technology areas, rank #5,145 of 50,000 tracked assignees.
Cambridge Mechatronics Limited has been granted 67 US utility patents between 2015 and 2025, placing Cambridge Mechatronics Limited at rank #5,145 across all assignees tracked by PlainPatent. This portfolio spans 24 distinct Cooperative Patent Classification (CPC) subclasses, averaging 19.6 claims per patent with primary concentration in F03G (SPRING, WEIGHT, INERTIA OR LIKE MOTORS; MECHANICAL-POWER PRODUCING DEVICES OR MECHANISMS, NOT OTHERWISE PROVIDED FOR OR USING ENERGY SOURCES NOT OTHERWISE PROVIDED FOR). As a Foreign Corporation, Cambridge Mechatronics Limited is one of the more focused assignees in the PatentsView dataset. By volume, Cambridge sits between Ancestry.com Operations Inc. (67 patents, rank #5,141) and China Medical University (67 patents, rank #5,149) - the closest US assignees by grant volume. The composite Innovation Score of 63.6/100 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 58 grants, compared with 9 in the 2015–2019 window, a +544% 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. Cambridge Mechatronics Limited's 19.6 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 24 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Cambridge Mechatronics Limited against peers pursuing similar technology classes.

How to use this portfolio
Cambridge's 67 grants land it in the top 2% 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.
