Does more volume mean deeper claims for York?

Each dot is one of York’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). York’s own 16.9 claims/patent is ABOVE the 7.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where York's grants concentrate

York Potash Ltd is a focused PatentsView assignee: 11 CPC subclasses with 100% of grants classified under 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-). Peak complete grant year is 2021 (4 grants) versus a trough of 1 in 2019. By volume, York sits between Yetter Manufacturing Company and Yajun Hu, Eureka LLC.

York's three-year grant acceleration

York Potash Ltd shows 2 grants in 2022–2024 against only 6 in 2019–2021. That prior window is too thin for a growth multiple (rename and spin-out assignees look artificially high when the baseline is near zero), so PlainPatent withholds a ranked acceleration claim here.
