The verdict
Downing holds 29 US patents across 4 technology areas, rank #10,599 of 50,000 tracked assignees.
Downing Wellhead Equipment, Llc has been granted 29 US utility patents between 2020 and 2025, placing Downing Wellhead Equipment, Llc at rank #10,599 across all assignees tracked by PlainPatent. This portfolio spans 4 distinct Cooperative Patent Classification (CPC) subclasses, averaging 27.2 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, Downing Wellhead Equipment, Llc is one of the more focused assignees in the PatentsView dataset. By volume, Downing sits between Depuy International Limited (29 patents, rank #10,595) and Enswers Co., Ltd. (29 patents, rank #10,603) - the closest US assignees by grant volume. The composite Innovation Score of 45.1/100 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. Historical data spans 2020 through 2025, with 29 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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. Downing Wellhead Equipment, Llc's 27.2 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while specialization in 4 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Downing Wellhead Equipment, Llc against peers pursuing similar technology classes.

How to use this portfolio
Downing's 29 grants land it in the top 24% 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.
