Does more volume mean deeper claims for Demby?

Each dot is one of Demby’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). Demby’s own 9.5 claims/patent is at or below the 13.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Demby's grants concentrate

Demby Development Co., Ltd. is a focused PatentsView assignee: 5 CPC subclasses with 84.6% of grants classified under E06B (Fixed OR Movable Closures FOR Openings IN Buildings, Vehicles, Fences OR Like Enclosures IN General, e.g. Doors, Windows, Blinds, Gates). Peak complete grant year is 2021 (5 grants) versus a trough of 1 in 2018. By volume, Demby sits between Dashamerica, Inc. and Diesel S.P.A..

Demby's three-year grant acceleration

Demby Development Co., Ltd. shows 5 grants in 2022–2024 against only 7 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.
