What this shows Dominion's Innovation Score is 38.0/100 (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 Dominion?

Each dot is one of Dominion’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). Dominion’s own 18.3 claims/patent is ABOVE the 10.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Dominion's grants concentrate

Dominion Engineering, Inc. is a focused PatentsView assignee: 13 CPC subclasses with 62.5% of grants classified under G21C (Nuclear Reactors). Peak complete grant year is 2017 (2 grants) versus a trough of 1 in 2016. By volume, Dominion sits between DMC, Inc and Douxmatok Ltd.

Dominion's three-year grant acceleration

Dominion Engineering, Inc. shows 2 grants in 2022–2024 against only 2 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.
