The verdict
Vulcan holds 7 US patents across 1 technology areas, rank #38,173 of 50,000 tracked assignees.
Vulcan Completion Products UK Limited has been granted 7 US utility patents between 2021 and 2025, placing Vulcan Completion Products UK Limited at rank #38,173 across all assignees tracked by PlainPatent. This portfolio spans 1 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.9 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, Vulcan Completion Products UK Limited is one of the more focused assignees in the PatentsView dataset. By volume, Vulcan sits between VK Integrated Systems, Inc. (7 patents, rank #38,169) and Vanmark Equipment, Llc (7 patents, rank #38,177) - the closest US assignees by grant volume. The composite Innovation Score of 37.8/100 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 2021 through 2025, with 7 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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. Vulcan Completion Products UK Limited's 11.9 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while specialization in 1 subclass reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Vulcan Completion Products UK Limited against peers pursuing similar technology classes.

How to use this portfolio
Vulcan's 7 grants land it in the top 42% 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.
