What this shows STC's Innovation Score is 45.8/100 (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 STC?

Each dot is one of STC’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). STC’s own 14.1 claims/patent is at or below the 15.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where STC's grants concentrate

STC, Inc. is a focused PatentsView assignee: 8 CPC subclasses with 93.1% of grants classified under G08G (Traffic Control Systems). Peak complete grant year is 2023 (6 grants) versus a trough of 1 in 2019. By volume, STC sits between Sistema Plastics Limited and Suez Groupe.

STC's three-year grant acceleration

STC, Inc. shows 14 grants in 2022–2024 against only 6 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.
