What this shows Seatwirl's Innovation Score is 27.7/100 (24th 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 Seatwirl?

Each dot is one of Seatwirl’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). Seatwirl’s own 11.7 claims/patent is ABOVE the 10.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Seatwirl's grants concentrate

Seatwirl AB is a focused PatentsView assignee: 11 CPC subclasses with 100% of grants classified under Y02E (Reduction OF Greenhouse GAS [GHG] Emissions, Related TO Energy Generation, Transmission OR Distribution). Peak complete grant year is 2020 (2 grants) versus a trough of 1 in 2017. By volume, Seatwirl sits between Sealink Corp. and SEE—Soluções, Energia e Meio Ambiente Ltda..

Seatwirl's three-year grant acceleration

Seatwirl AB shows 1 grants in 2022–2024 against only 3 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.
