Does more volume mean deeper claims for Concraft?
Each dot is one of Concraft’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). Concraft’s own 10.5 claims/patent is at or below the 10.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
Where Concraft's grants concentrate
Concraft Holding Co., Ltd. is a focused PatentsView assignee: 18 CPC subclasses with 36.4% of grants classified under H04R (Loudspeakers, Microphones, Gramophone Pick-ups OR Like Acoustic Electromechanical TRANSDUCERS; Deaf-aid SETS; Public Address Systems). Peak complete grant year is 2020 (8 grants) versus a trough of 1 in 2016. By volume, Concraft sits between Changs Ascending Enterprise Co., Ltd. and Crypto LAB Inc..
Concraft's three-year grant acceleration
Concraft Holding Co., Ltd. shows 1 grants in 2022–2024 against only 13 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.
