What this shows EA's Innovation Score is 36.1/100 (top 47% 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 EA?

Each dot is one of EA’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). EA’s own 15.3 claims/patent is ABOVE the 14.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where EA's grants concentrate

EA Pharma Co., Ltd. is a focused PatentsView assignee: 15 CPC subclasses with 84.2% of grants classified under A61P (Specific Therapeutic Activity OF Chemical Compounds OR Medicinal Preparations). Peak complete grant year is 2017 (5 grants) versus a trough of 1 in 2016. By volume, EA sits between Differential Dynamics Corporation and Echostar Ukraine, L.L.C..

EA's three-year grant acceleration

EA Pharma Co., Ltd. shows 3 grants in 2022–2024 against only 7 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.
