What this shows Thornton's Innovation Score is 28.1/100 (26th 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 Thornton?

Each dot is one of Thornton’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). Thornton’s own 14.2 claims/patent is at or below the 14.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Thornton's grants concentrate

Thornton Tomasetti Limited is a focused PatentsView assignee: 10 CPC subclasses with 33.3% of grants classified under E04F (Finishing Work ON Buildings, e.g. Stairs, Floors). Peak complete grant year is 2021 (2 grants) versus a trough of 1 in 2017. By volume, Thornton sits between Thintronics, Inc. and ThyssenKrupp Bilstein of America Inc..

Thornton's three-year grant acceleration

Thornton Tomasetti Limited shows 1 grants in 2022–2024 against only 4 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.
