Does more volume mean deeper claims for Kingclean?
Each dot is one of Kingclean’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). Kingclean’s own 9.5 claims/patent is at or below the 12.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
Where Kingclean's grants concentrate
Kingclean Electric Co., Ltd. is a focused PatentsView assignee: 7 CPC subclasses with 69.2% 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 2023. By volume, Kingclean sits between Kepler Vision Technologies B.V. and Kohler Interiors Furniture Company.
Kingclean's three-year grant acceleration
Kingclean Electric Co., Ltd. shows 5 grants in 2022–2024 against only 7 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.
