What this shows Tokamak's Innovation Score is 44.5/100 (top 26% 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 Tokamak?

Each dot is one of Tokamak’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). Tokamak’s own 14.2 claims/patent is at or below the 14.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Tokamak's grants concentrate

Tokamak Energy Ltd is a focused PatentsView assignee: 21 CPC subclasses with 86.8% of grants classified under Y02E (Reduction OF Greenhouse GAS [GHG] Emissions, Related TO Energy Generation, Transmission OR Distribution). Peak complete grant year is 2021 (8 grants) versus a trough of 1 in 2017. By volume, Tokamak sits between Tekion Corp and VDyne, Inc..

Tokamak's three-year grant acceleration

Tokamak Energy Ltd shows 17 grants in 2022–2024 against only 16 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.
