Does more volume mean deeper claims for Marshall?

Each dot is one of Marshall’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). Marshall’s own 15.7 claims/patent is ABOVE the 14.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Marshall's grants concentrate

Marshall Excelsior Co. is a focused PatentsView assignee: 16 CPC subclasses with 52.2% of grants classified under Y10T (Technical Subjects Covered BY Former US Classification). Peak complete grant year is 2016 (6 grants) versus a trough of 1 in 2015. By volume, Marshall sits between Mullen Technologies, Inc. and Megabyte Limited.

Marshall's three-year grant acceleration

Marshall Excelsior Co. shows 4 grants in 2022–2024 against only 5 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.
