What this shows Shenyang's Innovation Score is 43.6/100 (top 28% 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 Shenyang?

Each dot is one of Shenyang’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). Shenyang’s own 18.0 claims/patent is ABOVE the 2.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Shenyang's grants concentrate

Shenyang Kangende Medical Science and Technology Co., Ltd. is a focused PatentsView assignee: 3 CPC subclasses with 100% of grants classified under G02C (SPECTACLES; Sunglasses OR Goggles Insofar AS They Have THE Same Features AS SPECTACLES; Contact Lenses). Peak complete grant year is 2024 (3 grants) versus a trough of 2 in 2023. By volume, Shenyang sits between Shanghai dpdupi lighting electrical co. Ltd and Shenzhen Airtok Technology Co., Ltd..

Shenyang's three-year grant acceleration

Shenyang Kangende Medical Science and Technology Co., Ltd. shows 5 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.
