What this shows Chunghwa's Innovation Score is 32.2/100 (40th 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.
Chunghwa Chemical Synthesis & Biotech Co. Ltd. is a focused PatentsView assignee: 9 CPC subclasses with 50% of grants classified under C07D (Heterocyclic Compounds). Peak complete grant year is 2021 (2 grants) versus a trough of 1 in 2017. By volume, Chunghwa sits between Christiana Care Health System, Inc. and Cisbio Bioassays.
Chunghwa Chemical Synthesis & Biotech Co. Ltd. shows 3 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.
