What this shows Yangtze's Innovation Score is 34.0/100 (46th 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 Yangtze?

Each dot is one of Yangtze’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). Yangtze’s own 11.6 claims/patent is ABOVE the 10.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Yangtze's grants concentrate

Yangtze Optical Fibre AND Cable Joint Stock Limited Company is a focused PatentsView assignee: 11 CPC subclasses with 92.9% of grants classified under G02B (Optical Elements, Systems OR Apparatus). Peak complete grant year is 2020 (6 grants) versus a trough of 1 in 2022. By volume, Yangtze sits between World Emergency Network-Nevada, Ltd. and Zhongshan Yinghao Solar Technology Co., Ltd..

Yangtze's three-year grant acceleration

Yangtze Optical Fibre AND Cable Joint Stock Limited Company shows 5 grants in 2022–2024 against only 9 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.
