Portfolio overview

Varel International IND., L.l.c. has been granted 49 US utility patents between 2015 and 2021, placing Varel International IND., L.l.c. at rank #6,856 across all assignees tracked by PlainPatent. This portfolio spans 18 distinct Cooperative Patent Classification (CPC) subclasses, averaging 19.0 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, Varel International IND., L.l.c. is one of the more focused assignees in the PatentsView dataset. By volume, Varel sits between University Public Corporation Osaka (49 patents, rank #6,852) and XAAR Technology Limited (49 patents, rank #6,860) - the closest US assignees by grant volume. The composite Innovation Score of 39.9/100 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 7 grants, compared with 42 in the 2015–2019 window, a -83% 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. Varel International IND., L.l.c.'s 19.0 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 18 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Varel International IND., L.l.c. 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.
