The verdict
Liberty holds 10 US patents across 13 technology areas, rank #26,757 of 50,000 tracked assignees.
Liberty Ollfield Services Llc has been granted 10 US utility patents between 2020 and 2024, placing Liberty Ollfield Services Llc at rank #26,757 across all assignees tracked by PlainPatent. This portfolio spans 13 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.8 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, Liberty Ollfield Services Llc is one of the more focused assignees in the PatentsView dataset. By volume, Liberty sits between Lee Valley Tools Ltd. (10 patents, rank #26,753) and Linktel Technologies Co., Ltd. (10 patents, rank #26,761) - the closest US assignees by grant volume. The composite Innovation Score of 39.3/100 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 2024, with 10 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. Liberty Ollfield Services Llc's 13.8 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 13 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Liberty Ollfield Services Llc against peers pursuing similar technology classes.

How to use this portfolio
Liberty's 10 grants land it in the top 38% 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.
