Portfolio overview

Epiroc ROCK Drills Aktiebolag has been granted 35 US utility patents between 2018 and 2025, placing Epiroc ROCK Drills Aktiebolag at rank #9,022 across all assignees tracked by PlainPatent. This portfolio spans 30 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.8 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, Epiroc ROCK Drills Aktiebolag is one of the more focused assignees in the PatentsView dataset. By volume, Epiroc sits between DET International Holding Limited (35 patents, rank #9,018) and Electrolux Do Brasil S.a. (35 patents, rank #9,026) - the closest US assignees by grant volume. The composite Innovation Score of 47.9/100 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 16 grants, compared with 19 in the 2015–2019 window, a -16% 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. Epiroc ROCK Drills Aktiebolag's 15.8 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 30 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Epiroc ROCK Drills Aktiebolag against peers pursuing similar technology classes.

How to use this portfolio

Epiroc's 35 grants land it in the top 18% by Innovation Score, but volume alone doesn't tell you where the strength sits.

  • Read that count against the largest US assignees before treating it as dominance - Epiroc ranks #9,022 of 50,000. Top 50 holders
  • 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.
