Where Norsk's grants concentrate

Norsk Hydro ASA is a focused PatentsView assignee: 28 CPC subclasses with 32% of grants classified under C22C (Alloys). Peak complete grant year is 2021 (6 grants) versus a trough of 1 in 2019. By volume, Norsk sits between Nearmap Australia PTY Ltd. and Naver Business Platform Corporation.

Norsk's three-year grant acceleration

Norsk Hydro ASA shows 11 grants in 2022–2024 against only 8 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.
