The verdict
Petróleo holds 185 US patents across 112 technology areas, rank #2,132 of 50,000 tracked assignees.
Petróleo Brasileiro S.a.—petrobras has been granted 185 US utility patents between 2015 and 2025, placing Petróleo Brasileiro S.a.—petrobras at rank #2,132 across all assignees tracked by PlainPatent. This portfolio spans 112 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.8 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, Petróleo Brasileiro S.a.—petrobras is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Petróleo sits between Cooler Master Co., Ltd. (185 patents, rank #2,128) and Zedel (185 patents, rank #2,136) - the closest US assignees by grant volume. The composite Innovation Score of 70.2/100 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 151 grants, compared with 34 in the 2015–2019 window, a +344% 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. Petróleo Brasileiro S.a.—petrobras's 11.8 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, 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 Petróleo Brasileiro S.a.—petrobras against peers pursuing similar technology classes.

How to use this portfolio
Petróleo's 185 grants land it in the top 0.1% 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.
