Does more volume mean deeper claims for Shenzhen?

Each dot is one of Shenzhen’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). Shenzhen’s own 14.0 claims/patent is ABOVE the 1.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Shenzhen's grants concentrate

Shenzhen Bluetrum Technology Co., Ltd. is a focused PatentsView assignee: 7 CPC subclasses with 42.9% 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 2023 (3 grants) versus a trough of 1 in 2021. By volume, Shenzhen sits between Shenzhen Adaps Photonics Technology Co. Ltd. and Shenzhen Dalianpin Technology Trading Co., Ltd..

Shenzhen's three-year grant acceleration

Shenzhen Bluetrum Technology Co., Ltd. shows 4 grants in 2022–2024 against only 1 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.
