What this shows Yejia's Innovation Score is 24.7/100 (15th percentile 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 Yejia?

Each dot is one of Yejia’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). Yejia’s own 11.7 claims/patent is ABOVE the 8.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Yejia's grants concentrate

Yejia Optical Technology (GUANGDONG) Corporation is a focused PatentsView assignee: 7 CPC subclasses with 66.7% of grants classified under G02B (Optical Elements, Systems OR Apparatus). Peak complete grant year is 2021 (3 grants) versus a trough of 1 in 2020. By volume, Yejia sits between Yamato Protec Corporation and Yongfeng Boyuan Industry Co., Ltd., Jiangxi Province.

Yejia's three-year grant acceleration

Yejia Optical Technology (GUANGDONG) Corporation shows 1 grants in 2022–2024 against only 4 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.
