Portfolio overview
Cambridge Resonant Technologies Ltd. has been granted 6 US utility patents between 2015 and 2018, placing Cambridge Resonant Technologies Ltd. at rank #39,487 across all assignees tracked by PlainPatent. This portfolio spans 7 distinct Cooperative Patent Classification (CPC) subclasses, averaging 22.7 claims per patent with primary concentration in G06K (GRAPHICAL DATA READING ; PRESENTATION OF DATA; RECORD CARRIERS; HANDLING RECORD CARRIERS). As a Foreign Corporation, Cambridge Resonant Technologies Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Cambridge sits between California Exotic Novelties Llc (6 patents, rank #39,483) and Can-am Tool Corp. (6 patents, rank #39,491) - the closest US assignees by grant volume. The composite Innovation Score of 29.7/100 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 0 grants, compared with 6 in the 2015–2019 window, a -100% 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. Cambridge Resonant Technologies Ltd.'s 22.7 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while concentration in 7 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Cambridge Resonant Technologies Ltd. against peers pursuing similar technology classes.

- Most of this portfolio concentrates in G06K - see who else leads that technology area. G06K leaders
- Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works
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.
