Does more volume mean deeper claims for Spartan?

Each dot is one of Spartan’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). Spartan’s own 16.7 claims/patent is ABOVE the 11.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Spartan's grants concentrate

Spartan Chemical Company, Inc. is a focused PatentsView assignee: 5 CPC subclasses with 58.3% of grants classified under C08L (Compositions OF Macromolecular Compounds). Peak complete grant year is 2020 (2 grants) versus a trough of 1 in 2018. By volume, Spartan sits between Solo Gelato Ltd. and Speedx PTY Ltd.

Spartan's three-year grant acceleration

Spartan Chemical Company, Inc. 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.
