Where Shedrain's grants concentrate

Shedrain Corporation is a focused PatentsView assignee: 3 CPC subclasses with 57.1% of grants classified under A45B (Walking Sticks ; UMBRELLAS; Ladies' OR Like Fans). Peak complete grant year is 2023 (7 grants) versus a trough of 1 in 2018. By volume, Shedrain sits between SF Diamond Co., Ltd. and Ship AND Ocean Industries R&dcenter.

Shedrain's three-year grant acceleration

Shedrain Corporation shows 9 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.
