What this shows At&s(china)'s Innovation Score is 41.6/100 (top 33% 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 At&s(china)?

Each dot is one of At&s(china)’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). At&s(china)’s own 18.1 claims/patent is at or below the 18.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where At&s(china)'s grants concentrate

AT&S(China) Co. Ltd. is a focused PatentsView assignee: 13 CPC subclasses with 97.1% of grants classified under H05K (Printed CIRCUITS; Casings OR Constructional Details OF Electric APPARATUS; Manufacture OF Assemblages OF Electrical Components). Peak complete grant year is 2021 (9 grants) versus a trough of 2 in 2019. By volume, At&s(china) sits between Adocia and Aileron Therapeutics, Inc..

At&s(china)'s three-year grant acceleration

AT&S(China) Co. Ltd. shows 16 grants in 2022–2024 against only 19 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.
