What this shows Singer's Innovation Score is 50.4/100 (top 13% of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for Singer?

Each dot is one of Singer’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). Singer’s own 16.1 claims/patent is at or below the 17.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Singer's grants concentrate

Singer Sourcing Limited LLC is a focused PatentsView assignee: 10 CPC subclasses with 66.7% of grants classified under D05B (Sewing). Peak complete grant year is 2023 (5 grants) versus a trough of 1 in 2017. By volume, Singer sits between SignalFox, Inc. and Smart Packaging Solutions.

Singer's three-year grant acceleration

Singer Sourcing Limited LLC shows 10 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.
