Portfolio overview

Lufkin Industries, Llc has been granted 11 US utility patents between 2015 and 2020, placing Lufkin Industries, Llc at rank #24,718 across all assignees tracked by PlainPatent. This portfolio spans 13 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.4 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, Lufkin Industries, Llc is one of the more focused assignees in the PatentsView dataset. By volume, Lufkin sits between Linx Printing Technologies Limited (11 patents, rank #24,714) and Lzlabs Gmbh (11 patents, rank #24,722) - the closest US assignees by grant volume. The composite Innovation Score of 30.6/100 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 10 in the 2015–2019 window, a -90% 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. Lufkin Industries, Llc's 15.4 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 Lufkin Industries, Llc against peers pursuing similar technology classes.
