Does more volume mean deeper claims for King?

Each dot is one of King’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). King’s own 9.7 claims/patent is at or below the 14.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where King's grants concentrate

King LAI Hygienic Materials Co., Ltd is a focused PatentsView assignee: 4 CPC subclasses with 90% of grants classified under F16K (VALVES; TAPS; COCKS; ACTUATING-FLOATS; Devices FOR Venting OR Aerating). Peak complete grant year is 2016 (3 grants) versus a trough of 1 in 2017. By volume, King sits between Kettering University and KLA-Tencor Technologies Corp..

King's three-year grant acceleration

King LAI Hygienic Materials Co., Ltd shows 4 grants in 2022–2024 against only 1 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.
