Portfolio overview

Cameron International Corporation has been granted 692 US utility patents between 2015 and 2025, placing Cameron International Corporation at rank #644 across all assignees tracked by PlainPatent. This portfolio spans 120 distinct Cooperative Patent Classification (CPC) subclasses, averaging 18.2 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, Cameron International Corporation is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Cameron sits between Arizona Board Of Regents On Behalf Of The University Of Arizona (696 patents, rank #640) and Immatics Biotechnologies Gmbh (690 patents, rank #648) - the closest US assignees by grant volume. The composite Innovation Score of 62.0/100 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 213 grants, compared with 479 in the 2015–2019 window, a -56% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. Cameron International Corporation's 18.2 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a diversified footprint across 100+ CPC subclasses spreads risk across many technology fronts. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Cameron International Corporation against peers pursuing similar technology classes.

How to use this portfolio

Cameron's 692 grants land it in the top 3% 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 - Cameron ranks #644 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.
