Does more volume mean deeper claims for Danxiao?
Each dot is one of Danxiao’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). Danxiao’s own 13.3 claims/patent is at or below the 16.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
Where Danxiao's grants concentrate
Danxiao Information Tech Ltd. is a focused PatentsView assignee: 10 CPC subclasses with 41.7% of grants classified under A61H (Physical Therapy Apparatus, e.g. Devices FOR Locating OR Stimulating Reflex Points IN THE BODY; Artificial RESPIRATION; MASSAGE; Bathing Devices FOR Special Therapeutic OR Hygienic Purposes OR Specifi). Peak complete grant year is 2022 (6 grants) versus a trough of 1 in 2017. By volume, Danxiao sits between D.C. Water and Sewer Authority and DE Grisogono S.A..
Danxiao's three-year grant acceleration
Danxiao Information Tech Ltd. shows 8 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.
