Where Digger's grants concentrate

Digger Specialties, Inc. is a focused PatentsView assignee: 6 CPC subclasses with 50% of grants classified under E04F (Finishing Work ON Buildings, e.g. Stairs, Floors). Peak complete grant year is 2019 (2 grants) versus a trough of 1 in 2015. By volume, Digger sits between Dextera Surgical and Dip-Tech, Ltd..

Digger's three-year grant acceleration

Digger Specialties, Inc. 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.
