Portfolio overview

Drillform Technical Services Ltd. has been granted 11 US utility patents between 2019 and 2025, placing Drillform Technical Services Ltd. at rank #24,196 across all assignees tracked by PlainPatent. This portfolio spans 8 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.8 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 Foreign Corporation, Drillform Technical Services Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Drillform sits between Dornbracht Ag & Co. KG (11 patents, rank #24,192) and Dezurik, Inc. (11 patents, rank #24,200) - the closest US assignees by grant volume. The composite Innovation Score of 30.3/100 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 8 grants, compared with 3 in the 2015–2019 window, a +167% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. The Foreign 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. Drillform Technical Services Ltd.'s 14.8 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 Drillform Technical Services Ltd. against peers pursuing similar technology classes.

  • Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works

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.
