Cammenga Company, Llc has been granted 6 US utility patents between 2017 and 2019, placing Cammenga Company, Llc at rank #39,298 across all assignees tracked by PlainPatent. This portfolio spans 9 distinct Cooperative Patent Classification (CPC) subclasses, averaging 17.8 claims per patent with primary concentration in B26B (HAND-HELD CUTTING TOOLS NOT OTHERWISE PROVIDED FOR). As a US Corporation, Cammenga Company, Llc is one of the more focused assignees in the PatentsView dataset. By volume, Cammenga sits between Cakeboxx Technologies, Llc (6 patents, rank #39,294) and Canberra Industries, Inc. (6 patents, rank #39,302) - the closest US assignees by grant volume. The composite Innovation Score of 28.0/100 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 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 US 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. Cammenga Company, Llc's 17.8 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 9 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Cammenga Company, Llc against peers pursuing similar technology classes.

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.
