What this shows Kamtec's Innovation Score is 37.5/100 (top 43% 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 Kamtec?

Each dot is one of Kamtec’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). Kamtec’s own 22.5 claims/patent is ABOVE the 12.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Kamtec's grants concentrate

Kamtec Inc. is a focused PatentsView assignee: 9 CPC subclasses with 50% 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 2016 (2 grants) versus a trough of 1 in 2015. By volume, Kamtec sits between Kallyope, Inc. and Katoh Electric Co., Ltd..

Kamtec's three-year grant acceleration

Kamtec Inc. 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.
