The verdict
Interwell holds 9 US patents across 4 technology areas, rank #29,063 of 50,000 tracked assignees.
Interwell P&A AS has been granted 9 US utility patents between 2017 and 2025, placing Interwell P&A AS at rank #29,063 across all assignees tracked by PlainPatent. This portfolio spans 4 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.0 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 Foreign Corporation, Interwell P&A AS is one of the more focused assignees in the PatentsView dataset. By volume, Interwell sits between Integrated Micro-chromatography Systems, Inc. (9 patents, rank #29,059) and Invetx, Inc. (9 patents, rank #29,067) - the closest US assignees by grant volume. The composite Innovation Score of 43.4/100 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 1 in the 2015–2019 window, a +700% 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. Interwell P&A AS's 14.0 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while specialization in 4 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Interwell P&A AS against peers pursuing similar technology classes.

How to use this portfolio
Interwell's 9 grants land it in the top 28% by Innovation Score, but volume alone doesn't tell you where the strength sits.
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.
