Does more volume mean deeper claims for Twin-star?

Each dot is one of Twin-star’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). Twin-star’s own 13.5 claims/patent is at or below the 13.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Twin-star's grants concentrate

Twin-star International, Inc. is a focused PatentsView assignee: 20 CPC subclasses with 23.8% of grants classified under F24C (Domestic Stoves OR Ranges ; Details OF Domestic Stoves OR Ranges, OF General Application). Peak complete grant year is 2016 (5 grants) versus a trough of 1 in 2015. By volume, Twin-star sits between Truck Accessories Group, LLC and Telogis, Inc..

Twin-star's three-year grant acceleration

Twin-star International, Inc. shows 2 grants in 2022–2024 against only 10 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.
