What this shows Tunghai's Innovation Score is 50.5/100 (top 13% 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 Tunghai?

Each dot is one of Tunghai’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). Tunghai’s own 10.7 claims/patent is at or below the 15.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Tunghai's grants concentrate

Tunghai University is a focused PatentsView assignee: 26 CPC subclasses with 25% of grants classified under C07K (Peptides). Peak complete grant year is 2024 (4 grants) versus a trough of 1 in 2016. By volume, Tunghai sits between Toyota Motor Sales, U.S.A., Inc. and Thales Defense & Security, Inc..

Tunghai's three-year grant acceleration

Tunghai University shows 7 grants in 2022–2024 against only 3 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.
