STEWART & STEVENSON LLC

STEWART & STEVENSON LLC has been granted 22 US utility patents between 2015 and 2025, placing STEWART & STEVENSON LLC at rank #13,682 across all assignees tracked by PlainPatent. This portfolio spans 22 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.7 claims per patent with primary concentration in E21B (EARTH OR ROCK DRILLING; OBTAINING OIL, GAS, WATER, SOLUBLE OR MELTABLE MATERIALS OR A SLURRY OF MINERALS FROM WELLS). As a US Corporation, STEWART & STEVENSON LLC is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 56.8/100 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 18 grants, compared with 4 in the 2015–2019 window — a +350% 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. STEWART & STEVENSON LLC's 15.7 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 22 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark STEWART & STEVENSON LLC against peers pursuing similar technology classes.
