What this shows K.k.'s Innovation Score is 29.7/100 (32nd percentile 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 K.k.?

Each dot is one of K.k.’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). K.k.’s own 13.6 claims/patent is ABOVE the 11.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where K.k.'s grants concentrate

K.K. Sun Metalon is a focused PatentsView assignee: 6 CPC subclasses with 60% of grants classified under B33Y (Additive Manufacturing, i.e. Manufacturing OF Three-dimensional [3-D] Objects BY Additive Deposition, Additive Agglomeration OR Additive Layering, e.g. BY 3-D Printing, Stereolithography OR Selective ). By volume, K.k. sits between K-lab Corp. and Kaeco Group, Inc..

K.k.'s three-year grant acceleration

K.K. Sun Metalon shows 1 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.
