Where Hazen's grants concentrate

Hazen Paper Company is a focused PatentsView assignee: 14 CPC subclasses with 54.5% of grants classified under B32B (LAYERED PRODUCTS, i.e. PRODUCTS BUILT-UP OF STRATA OF FLAT OR NON-FLAT, e.g. CELLULAR OR HONEYCOMB, FORM). Peak complete grant year is 2018 (3 grants) versus a trough of 1 in 2015. By volume, Hazen sits between Hangzhou Valgen Medtech Co., Ltd. and Heidelbergcement Ag.

Hazen's three-year grant acceleration

Hazen Paper Company shows 3 grants in 2022–2024 against only 3 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.
