Does more volume mean deeper claims for Viskase?

Each dot is one of Viskase’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). Viskase’s own 22.4 claims/patent is ABOVE the 16.1 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Viskase's grants concentrate

Viskase Companies, Inc. is a focused PatentsView assignee: 16 CPC subclasses with 100% of grants classified under A22C (Processing Meat, Poultry, OR Fish). Peak complete grant year is 2022 (2 grants) versus a trough of 1 in 2017. By volume, Viskase sits between Virginia Venture Industries, LLC and Viza Electronics Pte. Ltd..

Viskase's three-year grant acceleration

Viskase Companies, Inc. shows 4 grants in 2022–2024 against only 0 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.
