Does more volume mean deeper claims for Topper?

Each dot is one of Topper’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). Topper’s own 16.3 claims/patent is ABOVE the 13.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Topper's grants concentrate

Topper Manufacturing Corporation is a focused PatentsView assignee: 4 CPC subclasses with 85.7% of grants classified under B01D (Separation). Peak complete grant year is 2019 (2 grants) versus a trough of 1 in 2017. By volume, Topper sits between Tohoku Magnet Institute Co., Ltd. and TouGas Oilfield Solutions GmbH.

Topper's three-year grant acceleration

Topper Manufacturing Corporation shows 2 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.
