What this shows Casco's Innovation Score is 55.1/100 (top 7% 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 Casco?

Each dot is one of Casco’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). Casco’s own 9.8 claims/patent is at or below the 15.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Casco's grants concentrate

Casco Signal Ltd. is a focused PatentsView assignee: 23 CPC subclasses with 76.5% of grants classified under B61L (Guiding Railway TRAFFIC; Ensuring THE Safety OF Railway Traffic). Peak complete grant year is 2024 (12 grants) versus a trough of 4 in 2023. By volume, Casco sits between Buffalo Filter LLC and Centaurus Biopharma Co., Ltd..

Casco's three-year grant acceleration

Casco Signal Ltd. shows 16 grants in 2022–2024 against only 0 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.
