What this shows Tunghsu's Innovation Score is 53.5/100 (top 9% 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 Tunghsu?

Each dot is one of Tunghsu’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). Tunghsu’s own 16.0 claims/patent is ABOVE the 10.1 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Tunghsu's grants concentrate

Tunghsu Group Co., Ltd. is a focused PatentsView assignee: 16 CPC subclasses with 56.3% of grants classified under C03B (Manufacture, Shaping, OR Supplementary Processes). Peak complete grant year is 2023 (7 grants) versus a trough of 1 in 2020. By volume, Tunghsu sits between TRC Recreation, LP and TXC Corporation.

Tunghsu's three-year grant acceleration

Tunghsu Group Co., Ltd. shows 14 grants in 2022–2024 against only 2 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.
