Portfolio overview

A. Finkl & Sons Co. has been granted 7 US utility patents between 2017 and 2020, placing A. Finkl & Sons Co. at rank #34,039 across all assignees tracked by PlainPatent. This portfolio spans 13 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.0 claims per patent with primary concentration in C22C (ALLOYS). As a US Corporation, A. Finkl & Sons Co. is one of the more focused assignees in the PatentsView dataset. By volume, A. sits between 9143-8010 Quebec Inc. (7 patents, rank #34,035) and AB Ludvig Svensson (7 patents, rank #34,043) - the closest US assignees by grant volume. The composite Innovation Score of 27.1/100 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 2 grants, compared with 5 in the 2015–2019 window, a -60% 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. A. Finkl & Sons Co.'s 12.0 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 13 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark A. Finkl & Sons Co. 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.
