What this shows Traffic's Innovation Score is 34.3/100 (47th 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 Traffic?

Each dot is one of Traffic’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). Traffic’s own 14.6 claims/patent is at or below the 17.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Traffic's grants concentrate

Traffic Control Technology Co., Ltd is a focused PatentsView assignee: 12 CPC subclasses with 100% of grants classified under B61L (Guiding Railway TRAFFIC; Ensuring THE Safety OF Railway Traffic). Peak complete grant year is 2020 (4 grants) versus a trough of 1 in 2023. By volume, Traffic sits between Thompson Aero Seating Limited and TriReme Medical, LLC.

Traffic's three-year grant acceleration

Traffic Control Technology Co., Ltd shows 5 grants in 2022–2024 against only 9 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.
