What this shows Powercell's Innovation Score is 32.5/100 (41st percentile 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 Powercell?

Each dot is one of Powercell’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). Powercell’s own 13.2 claims/patent is at or below the 14.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Powercell's grants concentrate

Powercell Sweden AB is a focused PatentsView assignee: 13 CPC subclasses with 85.7% of grants classified under Y02E (Reduction OF Greenhouse GAS [GHG] Emissions, Related TO Energy Generation, Transmission OR Distribution). Peak complete grant year is 2015 (8 grants) versus a trough of 1 in 2017. By volume, Powercell sits between Oz-Post International, LLC and Petrowell Limited.

Powercell's three-year grant acceleration

Powercell Sweden AB shows 1 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.
