Portfolio overview

Butts Properties, Ltd. has been granted 8 US utility patents between 2015 and 2020, placing Butts Properties, Ltd. at rank #31,112 across all assignees tracked by PlainPatent. This portfolio spans 8 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.9 claims per patent with primary concentration in F25J (LIQUEFACTION, SOLIDIFICATION OR SEPARATION OF GASES OR GASEOUS ; OR LIQUEFIED GASEOUS; MIXTURES BY PRESSURE AND COLD TREATMENT ; OR BY BRINGING THEM INTO THE SUPERCRITICAL STATE). As a US Corporation, Butts Properties, Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Butts sits between Bullard Spine, Llc (8 patents, rank #31,108) and C.m.i. Cerniere Meccaniche Industriali S.r.l. (8 patents, rank #31,116) - 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 1 grants, compared with 7 in the 2015–2019 window, a -86% 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. Butts Properties, Ltd.'s 15.9 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 8 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Butts Properties, Ltd. against peers pursuing similar technology classes.
