What this shows E2metrix's Innovation Score is 37.9/100 (top 42% 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 E2metrix?

Each dot is one of E2metrix’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). E2metrix’s own 16.5 claims/patent is ABOVE the 12.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where E2metrix's grants concentrate

E2metrix Inc. is a focused PatentsView assignee: 5 CPC subclasses with 100% of grants classified under C02F (Treatment OF Water, Waste Water, Sewage, OR Sludge). By volume, E2metrix sits between E-lids, LLC and Easy Healthcare Corporation.

E2metrix's three-year grant acceleration

E2metrix Inc. shows 2 grants in 2022–2024 against only 1 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.
