Does more volume mean deeper claims for Mcalpine?

Each dot is one of Mcalpine’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). Mcalpine’s own 19.1 claims/patent is ABOVE the 14.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Mcalpine's grants concentrate

McAlpine & Co. Ltd. is a focused PatentsView assignee: 6 CPC subclasses with 76.9% of grants classified under E03C (Domestic Plumbing Installations FOR Fresh Water OR Waste Water ; Sinks). Peak complete grant year is 2019 (4 grants) versus a trough of 1 in 2020. By volume, Mcalpine sits between Maxim Lighting International, Inc. and Medica Corporation.

Mcalpine's three-year grant acceleration

McAlpine & Co. Ltd. shows 2 grants in 2022–2024 against only 5 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.
