Does more volume mean deeper claims for Wagstaff?

Each dot is one of Wagstaff’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). Wagstaff’s own 18.8 claims/patent is ABOVE the 15.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Wagstaff's grants concentrate

Wagstaff, Inc. is a focused PatentsView assignee: 7 CPC subclasses with 100% of grants classified under B22D (Casting OF METALS; Casting OF Other Substances BY THE Same Processes OR Devices). Peak complete grant year is 2024 (5 grants) versus a trough of 1 in 2016. By volume, Wagstaff sits between Visual Physics, LLC and Wgrs Licensing Company, LLC.

Wagstaff's three-year grant acceleration

Wagstaff, Inc. shows 11 grants in 2022–2024 against only 4 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.
