What this shows Chunghwa's Innovation Score is 36.4/100 (top 46% 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 Chunghwa?

Each dot is one of Chunghwa’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). Chunghwa’s own 9.9 claims/patent is at or below the 17.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Chunghwa's grants concentrate

Chunghwa Telecom Co., Ltd. is a focused PatentsView assignee: 21 CPC subclasses with 51.9% of grants classified under H04L (Transmission OF Digital Information, e.g. Telegraphic Communication). Peak complete grant year is 2020 (7 grants) versus a trough of 1 in 2015. By volume, Chunghwa sits between Charm Sciences, Inc. and Contentful GmbH.

Chunghwa's three-year grant acceleration

Chunghwa Telecom Co., Ltd. shows 5 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.
