What this shows Kataoka's Innovation Score is 50.8/100 (top 12% 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 Kataoka?

Each dot is one of Kataoka’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). Kataoka’s own 12.7 claims/patent is ABOVE the 12.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Kataoka's grants concentrate

Kataoka Corporation is a focused PatentsView assignee: 14 CPC subclasses with 76.5% of grants classified under C12N (Microorganisms OR ENZYMES; Compositions THEREOF; Propagating, Preserving, OR Maintaining MICROORGANISMS; Mutation OR Genetic ENGINEERING; Culture Media). Peak complete grant year is 2022 (5 grants) versus a trough of 1 in 2016. By volume, Kataoka sits between Kyokutoh Co., Ltd. and Kionix, Inc..

Kataoka's three-year grant acceleration

Kataoka Corporation shows 13 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.
