Does more volume mean deeper claims for Quadratec?

Each dot is one of Quadratec’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). Quadratec’s own 18.6 claims/patent is ABOVE the 17.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Quadratec's grants concentrate

Quadratec, Inc. is a focused PatentsView assignee: 8 CPC subclasses with 60% of grants classified under B66D (CAPSTANS; WINCHES; Tackles, e.g. Pulley BLOCKS; Hoists). By volume, Quadratec sits between Qintel, LLC and Quality Innovative Products, LLC.

Quadratec's three-year grant acceleration

Quadratec, Inc. shows 2 grants in 2022–2024 against only 1 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.
