Portfolio overview

YORK Potash Ltd has been granted 8 US utility patents between 2019 and 2024, placing YORK Potash Ltd at rank #33,940 across all assignees tracked by PlainPatent. This portfolio spans 11 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.9 claims per patent with primary concentration in C05G (MIXTURES OF FERTILISERS COVERED INDIVIDUALLY BY DIFFERENT SUBCLASSES OF CLASS C05; MIXTURES OF ONE OR MORE FERTILISERS WITH MATERIALS NOT HAVING A SPECIFIC FERTILISING ACTIVITY, e.g. PESTICIDES, SOIL-). As a Foreign Corporation, YORK Potash Ltd is one of the more focused assignees in the PatentsView dataset. By volume, YORK sits between Yetter Manufacturing Company (8 patents, rank #33,936) and Yajun Hu, Eureka Llc (8 patents, rank #33,944) - the closest US assignees by grant volume. The composite Innovation Score of 31.7/100 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 7 grants, compared with 1 in the 2015–2019 window, a +600% 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. YORK Potash Ltd's 16.9 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 11 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark YORK Potash Ltd against peers pursuing similar technology classes.

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.
