What this shows Osang's Innovation Score is 26.0/100 (19th 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 Osang?

Each dot is one of Osang’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). Osang’s own 11.8 claims/patent is ABOVE the 7.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Osang's grants concentrate

Osang Healthcare Co., Ltd. is a focused PatentsView assignee: 7 CPC subclasses with 60% of grants classified under G01N (Investigating OR Analysing Materials BY Determining Their Chemical OR Physical Properties). By volume, Osang sits between Orlucent Inc. and Ossis Limited.

Osang's three-year grant acceleration

Osang Healthcare Co., Ltd. shows 1 grants in 2022–2024 against only 2 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.
