Does more volume mean deeper claims for Spellbound?
Each dot is one of Spellbound’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). Spellbound’s own 12.7 claims/patent is at or below the 13.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
Where Spellbound's grants concentrate
Spellbound Development Group, Inc. is a focused PatentsView assignee: 8 CPC subclasses with 70% of grants classified under B26B (Hand-held Cutting Tools NOT Otherwise Provided FOR). Peak complete grant year is 2019 (5 grants) versus a trough of 1 in 2015. By volume, Spellbound sits between Spark Biomedical, Inc. and SpringActive, Inc..
Spellbound's three-year grant acceleration
Spellbound Development Group, Inc. shows 1 grants in 2022–2024 against only 8 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.
