Portfolio overview

Center Rock Inc. has been granted 10 US utility patents between 2017 and 2025, placing Center Rock Inc. at rank #26,024 across all assignees tracked by PlainPatent. This portfolio spans 3 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 US Corporation, Center Rock Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Center sits between Casabella Holdings, L.l.c. (10 patents, rank #26,020) and Cerro Wire Llc (10 patents, rank #26,028) - the closest US assignees by grant volume. The composite Innovation Score of 23.9/100 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 6 grants, compared with 4 in the 2015–2019 window, a +50% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. Center Rock Inc.'s 15.8 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while specialization in 3 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Center Rock Inc. against peers pursuing similar technology classes.

How to use this portfolio

Center's 10 grants land it in the top 87% 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 - Center ranks #26,024 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.
