What this shows Yen's Innovation Score is 39.4/100 (top 38% 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 Yen?

Each dot is one of Yen’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). Yen’s own 5.3 claims/patent is at or below the 9.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Yen's grants concentrate

Yen Sun Technology Corp. is a focused PatentsView assignee: 6 CPC subclasses with 62.5% of grants classified under F04D (Non-positive-displacement Pumps). Peak complete grant year is 2023 (4 grants) versus a trough of 1 in 2020. By volume, Yen sits between Yves Saint Laurent Parfums and Youngblood IP Holdings, LLC.

Yen's three-year grant acceleration

Yen Sun Technology Corp. shows 4 grants in 2022–2024 against only 1 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.
