What this shows CT's Innovation Score is 45.7/100 (top 22% 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 CT?

Each dot is one of CT’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). CT’s own 18.5 claims/patent is ABOVE the 13.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where CT's grants concentrate

CT Energy Ltd. is a focused PatentsView assignee: 5 CPC subclasses with 50% of grants classified under F01P (Cooling OF Machines OR Engines IN GENERAL; Cooling OF Internal-combustion Engines). Peak complete grant year is 2024 (2 grants) versus a trough of 1 in 2015. By volume, CT sits between CSC Agility Platform, Inc. and Cummins Electrified Power NA Inc..

CT's three-year grant acceleration

CT Energy Ltd. shows 3 grants in 2022–2024 against only 1 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.
