What this shows Hazen's Innovation Score is 38.7/100 (top 40% 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 Hazen?

Each dot is one of Hazen’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). Hazen’s own 17.1 claims/patent is ABOVE the 15.1 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

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.
