What this shows Nanokem's Innovation Score is 42.6/100 (top 30% 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 Nanokem?

Each dot is one of Nanokem’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). Nanokem’s own 8.8 claims/patent is at or below the 13.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Nanokem's grants concentrate

Nanokem Co., Ltd. is a focused PatentsView assignee: 10 CPC subclasses with 80% of grants classified under G08B (Signalling OR Calling SYSTEMS; Order TELEGRAPHS; Alarm Systems). Peak complete grant year is 2024 (2 grants) versus a trough of 1 in 2022. By volume, Nanokem sits between Nanobridge Semiconductor, Inc. and Nanopaper, LLC.

Nanokem's three-year grant acceleration

Nanokem Co., Ltd. shows 3 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.
