What this shows Hanwha's Innovation Score is 45.7/100 (top 23% 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 Hanwha?

Each dot is one of Hanwha’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). Hanwha’s own 9.5 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 Hanwha's grants concentrate

Hanwha Total Petrochemical Co., Ltd. is a focused PatentsView assignee: 27 CPC subclasses with 35.3% of grants classified under Y02P (Climate Change Mitigation Technologies IN THE Production OR Processing OF Goods). Peak complete grant year is 2016 (4 grants) versus a trough of 1 in 2017. By volume, Hanwha sits between Guala Closures S.p.A. and Health Management Systems, Inc..

Hanwha's three-year grant acceleration

Hanwha Total Petrochemical Co., Ltd. shows 7 grants in 2022–2024 against only 4 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.
