Does more volume mean deeper claims for WM?

Each dot is one of WM’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). WM’s own 10.0 claims/patent is at or below the 13.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where WM's grants concentrate

WM Intellectual Property Holdings, L.L.C. is a focused PatentsView assignee: 42 CPC subclasses with 43.2% of grants classified under Y02W (Climate Change Mitigation Technologies Related TO Wastewater Treatment OR Waste Management). Peak complete grant year is 2023 (15 grants) versus a trough of 1 in 2015. By volume, WM sits between Teijin Pharma Limited and Aware, Inc..

WM's three-year grant acceleration

WM Intellectual Property Holdings, L.L.C. shows 41 grants in 2022–2024 against only 15 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.
