What this shows Taiwan's Innovation Score is 24.3/100 (14th 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 Taiwan?

Each dot is one of Taiwan’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). Taiwan’s own 4.6 claims/patent is at or below the 15.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Taiwan's grants concentrate

Taiwan Hopax Chemicals Mfg. Co., Ltd. is a focused PatentsView assignee: 10 CPC subclasses with 14.3% of grants classified under B42D (BOOKS; Book COVERS; Loose LEAVES; Printed Matter Characterised BY Identification OR Security FEATURES; Printed Matter OF Special Format OR Style NOT Otherwise Provided FOR; Devices FOR USE Therewith A). Peak complete grant year is 2015 (4 grants) versus a trough of 1 in 2020. By volume, Taiwan sits between TSI Manufacturing LLC and Tenax Energy Solution, LLC.

Taiwan's three-year grant acceleration

Taiwan Hopax Chemicals Mfg. Co., Ltd. shows 1 grants in 2022–2024 against only 7 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.
