Portfolio overview

Kerr Machine Co. has been granted 109 US utility patents between 2017 and 2025, placing Kerr Machine Co. at rank #3,400 across all assignees tracked by PlainPatent. This portfolio spans 18 distinct Cooperative Patent Classification (CPC) subclasses, averaging 18.1 claims per patent with primary concentration in F04B (POSITIVE-DISPLACEMENT MACHINES FOR LIQUIDS; PUMPS). As a US Corporation, Kerr Machine Co. is one of the more focused assignees in the PatentsView dataset. By volume, Kerr sits between Faurecia Interior Systems, Inc. (109 patents, rank #3,396) and Progressive International Corp. (109 patents, rank #3,404) - 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 105 grants, compared with 4 in the 2015–2019 window, a +2525% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. Kerr Machine Co.'s 18.1 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 18 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Kerr Machine Co. against peers pursuing similar technology classes.

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.
