What this shows Yungjin's Innovation Score is 35.3/100 (top 50% 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 Yungjin?

Each dot is one of Yungjin’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). Yungjin’s own 7.0 claims/patent is ABOVE the 5.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Yungjin's grants concentrate

Yungjin Pharm. Co., Ltd. is a focused PatentsView assignee: 9 CPC subclasses with 100% of grants classified under A61P (Specific Therapeutic Activity OF Chemical Compounds OR Medicinal Preparations). Peak complete grant year is 2016 (2 grants) versus a trough of 1 in 2015. By volume, Yungjin sits between Yongkang Chunkai Import & Export Co., Ltd and Yamato Corporation.

Yungjin's three-year grant acceleration

Yungjin Pharm. Co., Ltd. shows 2 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.
