What this shows Entrotech's Innovation Score is 45.0/100 (top 24% 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 Entrotech?

Each dot is one of Entrotech’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). Entrotech’s own 26.1 claims/patent is ABOVE the 17.1 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Entrotech's grants concentrate

Entrotech, Inc. is a focused PatentsView assignee: 18 CPC subclasses with 55% of grants classified under Y10T (Technical Subjects Covered BY Former US Classification). Peak complete grant year is 2017 (4 grants) versus a trough of 1 in 2015. By volume, Entrotech sits between Emergency Technology, Inc. and Evenflo Company, Inc..

Entrotech's three-year grant acceleration

Entrotech, Inc. shows 4 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.
