What this shows Phase's Innovation Score is 43.1/100 (top 29% 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 Phase?

Each dot is one of Phase’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). Phase’s own 14.4 claims/patent is at or below the 16.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Phase's grants concentrate

Phase Change Energy Solutions, Inc. is a focused PatentsView assignee: 17 CPC subclasses with 75% of grants classified under Y02E (Reduction OF Greenhouse GAS [GHG] Emissions, Related TO Energy Generation, Transmission OR Distribution). Peak complete grant year is 2018 (5 grants) versus a trough of 1 in 2017. By volume, Phase sits between Perdiemco LLC and Plantic Technologies Ltd..

Phase's three-year grant acceleration

Phase Change Energy Solutions, Inc. shows 7 grants in 2022–2024 against only 5 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.
