What this shows Feng's Innovation Score is 52.0/100 (top 11% 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 Feng?

Each dot is one of Feng’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). Feng’s own 11.5 claims/patent is at or below the 14.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Feng's grants concentrate

Feng Chia University is a focused PatentsView assignee: 37 CPC subclasses with 16.7% of grants classified under A61K (Preparations FOR Medical, Dental OR Toiletry Purposes). Peak complete grant year is 2015 (6 grants) versus a trough of 1 in 2022. By volume, Feng sits between Eveready Battery Company, Inc. and Furcifer Inc..

Feng's three-year grant acceleration

Feng Chia University 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.
