Portfolio overview

Statoil Petroleum AS has been granted 144 US utility patents between 2015 and 2023, placing Statoil Petroleum AS at rank #2,700 across all assignees tracked by PlainPatent. This portfolio spans 57 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.7 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 Foreign Corporation, Statoil Petroleum AS is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Statoil sits between Pilkington Group Limited (144 patents, rank #2,696) and Contemporary Visions, Llc (143 patents, rank #2,704) - the closest US assignees by grant volume. The composite Innovation Score of 52.5/100 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 21 grants, compared with 123 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 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. Statoil Petroleum AS's 16.7 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 57 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Statoil Petroleum AS against peers pursuing similar technology classes.

  • Most of this portfolio concentrates in E21B - see who else leads that technology area. E21B leaders
  • 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.
