What this shows Entrantech's Innovation Score is 57.1/100 (top 5% 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 Entrantech?

Each dot is one of Entrantech’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). Entrantech’s own 26.8 claims/patent is ABOVE the 14.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Entrantech's grants concentrate

Entrantech Inc. is a focused PatentsView assignee: 14 CPC subclasses with 75% of grants classified under H02J (Circuit Arrangements OR Systems FOR Supplying OR Distributing Electric POWER; Systems FOR Storing Electric Energy). Peak complete grant year is 2023 (4 grants) versus a trough of 1 in 2021. By volume, Entrantech sits between Elysium Health, Inc. and Esthetic Implant Solutions, LLC.

Entrantech's three-year grant acceleration

Entrantech Inc. shows 8 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.
