Does more volume mean deeper claims for Eptech?
Each dot is one of Eptech’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). Eptech’s own 12.9 claims/patent is at or below the 14.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
Where Eptech's grants concentrate
Eptech Co., Ltd. is a focused PatentsView assignee: 6 CPC subclasses with 100% of grants classified under E05Y (Indexing Scheme Associated With Subclasses E05d AND E05f, Relating TO Construction Elements, Electric Control, Power Supply, Power Signal OR Transmission, User Interfaces, Mounting OR Coupling, Detail). Peak complete grant year is 2024 (3 grants) versus a trough of 1 in 2020. By volume, Eptech sits between Epileds Technologies, Inc. and Esperance Pharmaceuticals, Inc..
Eptech's three-year grant acceleration
Eptech Co., Ltd. shows 4 grants in 2022–2024 against only 2 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.
