What this shows Semyungtech's Innovation Score is 44.5/100 (top 25% of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for Semyungtech?

Each dot is one of Semyungtech’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). Semyungtech’s own 11.0 claims/patent is ABOVE the 10.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Semyungtech's grants concentrate

Semyungtech Co., Ltd. is a focused PatentsView assignee: 10 CPC subclasses with 66.7% of grants classified under B60T (Vehicle Brake Control Systems OR Parts THEREOF; Brake Control Systems OR Parts Thereof, IN General ; Arrangement OF Braking Elements ON Vehicles IN GENERAL; Portable Devices FOR Preventing Unwanted MO). Peak complete grant year is 2022 (4 grants) versus a trough of 1 in 2023. By volume, Semyungtech sits between Sejong University Industry Academy Cooperation Foundation and Sentec E&E Co., Ltd..

Semyungtech's three-year grant acceleration

Semyungtech Co., Ltd. shows 6 grants in 2022–2024 against only 0 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.
