Where SWCC's grants concentrate

SWCC Showa Cable Systems Co., Ltd. is a focused PatentsView assignee: 19 CPC subclasses with 54.5% of grants classified under H01B (CABLES; CONDUCTORS; INSULATORS; SELECTION OF MATERIALS FOR THEIR CONDUCTIVE, INSULATING OR DIELECTRIC PROPERTIES). Peak complete grant year is 2015 (4 grants) versus a trough of 1 in 2016. By volume, SWCC sits between Suzhou Huazao Shunwei Intelligent Technology Co., Ltd. and Syntest Technologies, Inc..

SWCC's three-year grant acceleration

SWCC Showa Cable Systems Co., Ltd. shows 1 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.
