What this shows King's Innovation Score is 40.2/100 (top 36% 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 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 10.6 claims/patent is at or below the 15.2 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 Technology, Inc. is a focused PatentsView assignee: 15 CPC subclasses with 78.8% of grants classified under C02F (Treatment OF Water, Waste Water, Sewage, OR Sludge). Peak complete grant year is 2021 (11 grants) versus a trough of 2 in 2017. By volume, King sits between Kabushiki Kaisha Yakult Honsha and Landis+Gyr AG.

King's three-year grant acceleration

King Technology, Inc. shows 16 grants in 2022–2024 against only 19 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.
