Does more volume mean deeper claims for Epicmems(xiamen)?

Each dot is one of Epicmems(xiamen)’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). Epicmems(xiamen)’s own 9.5 claims/patent is at or below the 13.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Epicmems(xiamen)'s grants concentrate

EPICMEMS(XIAMEN) Co., Ltd. is a focused PatentsView assignee: 2 CPC subclasses with 83.3% of grants classified under H03H (Impedance Networks, e.g. Resonant CIRCUITS; Resonators). Peak complete grant year is 2024 (2 grants) versus a trough of 1 in 2021. By volume, Epicmems(xiamen) sits between Environmentally Safe Products, Inc. and Episys Science, Inc..

Epicmems(xiamen)'s three-year grant acceleration

EPICMEMS(XIAMEN) Co., Ltd. shows 3 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.
