What this shows EP's Innovation Score is 39.8/100 (top 37% of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for EP?

Each dot is one of EP’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). EP’s own 15.0 claims/patent is ABOVE the 14.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where EP's grants concentrate

EP Minerals LLC is a focused PatentsView assignee: 11 CPC subclasses with 100% of grants classified under B01J (Chemical OR Physical Processes, e.g. Catalysis OR Colloid CHEMISTRY; Their Relevant Apparatus). Peak complete grant year is 2019 (2 grants) versus a trough of 1 in 2015. By volume, EP sits between Enrichment Technology Company Ltd. and Erwin Junker Grinding Technology A.S..

EP's three-year grant acceleration

EP Minerals LLC shows 5 grants in 2022–2024 against only 3 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.
