Does more volume mean deeper claims for Drapho?

Each dot is one of Drapho’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). Drapho’s own 10.3 claims/patent is at or below the 15.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Drapho's grants concentrate

Drapho Electronics Technology., Ltd is a focused PatentsView assignee: 1 CPC subclasses with 100% of grants classified under H01R (Electrically-conductive CONNECTIONS; Structural Associations OF A Plurality OF Mutually-insulated Electrical Connecting ELEMENTS; Coupling DEVICES; Current Collectors). Peak complete grant year is 2016 (3 grants) versus a trough of 1 in 2018. By volume, Drapho sits between Dornoch Medical Systems, Inc. and Ductmate Industries, Inc..

Drapho's three-year grant acceleration

Drapho Electronics Technology., Ltd shows 1 grants in 2022–2024 against only 2 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.
