Does more volume mean deeper claims for Changzhou?
Each dot is one of Changzhou’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). Changzhou’s own 11.3 claims/patent is at or below the 12.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
Where Changzhou's grants concentrate
Changzhou AAC Raytech Optronics Co., Ltd. is a focused PatentsView assignee: 7 CPC subclasses with 66.7% of grants classified under H04N (Pictorial Communication, e.g. Television). Peak complete grant year is 2024 (11 grants) versus a trough of 3 in 2022. By volume, Changzhou sits between Cal Poly Corporation and Corporation for National Research Initiatives.
Changzhou's three-year grant acceleration
Changzhou AAC Raytech Optronics Co., Ltd. shows 19 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.
