What this shows Yotrio's Innovation Score is 53.4/100 (top 9% 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 Yotrio?

Each dot is one of Yotrio’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). Yotrio’s own 9.7 claims/patent is at or below the 13.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Yotrio's grants concentrate

Yotrio Group Co., Ltd. is a focused PatentsView assignee: 21 CPC subclasses with 30.8% of grants classified under A45B (Walking Sticks ; UMBRELLAS; Ladies' OR Like Fans). Peak complete grant year is 2017 (4 grants) versus a trough of 1 in 2015. By volume, Yotrio sits between Xuzhou Heavy Machinery Co., Ltd. and Zoomlion Heavy Industry NA, Inc..

Yotrio's three-year grant acceleration

Yotrio Group Co., Ltd. shows 6 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.
