What this shows Tamkang's Innovation Score is 44.9/100 (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 Tamkang?

Each dot is one of Tamkang’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). Tamkang’s own 12.5 claims/patent is at or below the 16.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Tamkang's grants concentrate

Tamkang University is a focused PatentsView assignee: 45 CPC subclasses with 11.5% of grants classified under H04W (Wireless Communication Networks). Peak complete grant year is 2020 (8 grants) versus a trough of 1 in 2024. By volume, Tamkang sits between Soroco Private Limited and THE Antenna Company International N.V..

Tamkang's three-year grant acceleration

Tamkang University shows 4 grants in 2022–2024 against only 12 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.
