Does more volume mean deeper claims for Protrend?
Each dot is one of Protrend’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). Protrend’s own 8.1 claims/patent is at or below the 16.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
Where Protrend's grants concentrate
Protrend Co., Ltd. is a focused PatentsView assignee: 5 CPC subclasses with 83.3% of grants classified under A47B (TABLES; DESKS; Office FURNITURE; CABINETS; DRAWERS; General Details OF Furniture). Peak complete grant year is 2023 (4 grants) versus a trough of 1 in 2015. By volume, Protrend sits between Premier Magnesia, LLC and Pain TEQ, LLC.
Protrend's three-year grant acceleration
Protrend Co., Ltd. shows 8 grants in 2022–2024 against only 0 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.
