Portfolio overview

Field Controls, Llc has been granted 16 US utility patents between 2016 and 2024, placing Field Controls, Llc at rank #17,669 across all assignees tracked by PlainPatent. This portfolio spans 15 distinct Cooperative Patent Classification (CPC) subclasses, averaging 17.8 claims per patent with primary concentration in F23L (SUPPLYING AIR OR NON-COMBUSTIBLE LIQUIDS OR GASES TO COMBUSTION APPARATUS IN GENERAL ; VALVES OR DAMPERS SPECIALLY ADAPTED FOR CONTROLLING AIR SUPPLY OR DRAUGHT IN COMBUSTION APPARATUS ; INDUCING DRA). As a US Corporation, Field Controls, Llc is one of the more focused assignees in the PatentsView dataset. By volume, Field sits between Frankie4 IP 1 Pty Ltd (16 patents, rank #17,665) and Florida Institute For Human And Machine Cognition, Inc. (16 patents, rank #17,673) - the closest US assignees by grant volume. The composite Innovation Score of 40.8/100 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 4 grants, compared with 12 in the 2015–2019 window, a -67% 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. Field Controls, Llc's 17.8 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 15 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Field Controls, Llc against peers pursuing similar technology classes.
