Does more volume mean deeper claims for Lin'an?

Each dot is one of Lin'an’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). Lin'an’s own 1.8 claims/patent is at or below the 13.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Lin'an's grants concentrate

Lin'an Thumb Cleaning Products Co., Ltd. is a focused PatentsView assignee: 3 CPC subclasses with 11.1% of grants classified under A47L (Domestic Washing OR Cleaning ; Suction Cleaners IN General). Peak complete grant year is 2020 (5 grants) versus a trough of 1 in 2019. By volume, Lin'an sits between LiftWerx Holdings Inc. and Lit Motors Corporation.

Lin'an's three-year grant acceleration

Lin'an Thumb Cleaning Products Co., Ltd. shows 1 grants in 2022–2024 against only 8 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.
