Does more volume mean deeper claims for China?

Each dot is one of China’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). China’s own 14.8 claims/patent is ABOVE the 14.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where China's grants concentrate

China Telecom Corporation Limited is a focused PatentsView assignee: 9 CPC subclasses with 76.9% of grants classified under H04W (Wireless Communication Networks). Peak complete grant year is 2024 (8 grants) versus a trough of 1 in 2016. By volume, China sits between Calmer Holding Company, LLC and Cardiac Assist Holdings, LLC.

China's three-year grant acceleration

China Telecom Corporation Limited shows 9 grants in 2022–2024 against only 0 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.
