Does more volume mean deeper claims for Maclean-fogg?

Each dot is one of Maclean-fogg’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). Maclean-fogg’s own 16.9 claims/patent is ABOVE the 13.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Maclean-fogg's grants concentrate

Maclean-Fogg Company is a focused PatentsView assignee: 21 CPC subclasses with 69.6% of grants classified under F16B (Devices FOR Fastening OR Securing Constructional Elements OR Machine Parts Together, e.g. Nails, Bolts, Circlips, Clamps, Clips OR WEDGES; Joints OR Jointing). Peak complete grant year is 2016 (4 grants) versus a trough of 1 in 2015. By volume, Maclean-fogg sits between Ming CHI University OF Technology and Mavenir Networks, Inc..

Maclean-fogg's three-year grant acceleration

Maclean-Fogg Company shows 6 grants in 2022–2024 against only 6 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.
