What this shows Posco's Innovation Score is 42.2/100 (top 31% 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 Posco?

Each dot is one of Posco’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). Posco’s own 7.6 claims/patent is at or below the 10.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Posco's grants concentrate

Posco Chemical Co., Ltd. is a focused PatentsView assignee: 8 CPC subclasses with 87.5% of grants classified under Y02E (Reduction OF Greenhouse GAS [GHG] Emissions, Related TO Energy Generation, Transmission OR Distribution). Peak complete grant year is 2024 (3 grants) versus a trough of 1 in 2021. By volume, Posco sits between Polaris Group and Power Spin Inc..

Posco's three-year grant acceleration

Posco Chemical Co., Ltd. shows 5 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.
