What this shows Touchstone's Innovation Score is 28.4/100 (27th 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 Touchstone?

Each dot is one of Touchstone’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). Touchstone’s own 8.4 claims/patent is at or below the 14.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Touchstone's grants concentrate

Touchstone Research Laboratory Ltd. is a focused PatentsView assignee: 10 CPC subclasses with 42.9% of grants classified under B32B (Layered Products, i.e. Products Built-up OF Strata OF Flat OR Non-flat, e.g. Cellular OR Honeycomb, Form). Peak complete grant year is 2021 (3 grants) versus a trough of 1 in 2020. By volume, Touchstone sits between Totally Tubular Mfg., Inc. and Tradecapture OTC Corp..

Touchstone's three-year grant acceleration

Touchstone Research Laboratory Ltd. shows 3 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.
