What this shows Taiwan's Innovation Score is 44.8/100 (top 25% 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 9.9 claims/patent is at or below the 11.9 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 Carbon Nano Technology Corporation is a focused PatentsView assignee: 23 CPC subclasses with 38.9% of grants classified under G01N (Investigating OR Analysing Materials BY Determining Their Chemical OR Physical Properties). Peak complete grant year is 2022 (3 grants) versus a trough of 1 in 2016. By volume, Taiwan sits between Szent Co. and TE Connectivity Sensors Germany GmbH.

Taiwan's three-year grant acceleration

Taiwan Carbon Nano Technology Corporation shows 7 grants in 2022–2024 against only 4 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.
