Does more volume mean deeper claims for Elevator?

Each dot is one of Elevator’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). Elevator’s own 17.4 claims/patent is ABOVE the 11.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Elevator's grants concentrate

Elevator Safety Company is a focused PatentsView assignee: 2 CPC subclasses with 100% of grants classified under B66B (ELEVATORS; Escalators OR Moving Walkways). Peak complete grant year is 2017 (2 grants) versus a trough of 1 in 2019. By volume, Elevator sits between Electricity North West Property Limited and Ellis Patents (HOLDINGS) Limited.

Elevator's three-year grant acceleration

Elevator Safety Company shows 2 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.
