What this shows Microwave's Innovation Score is 36.1/100 (top 47% 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 Microwave?

Each dot is one of Microwave’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). Microwave’s own 10.4 claims/patent is at or below the 14.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Microwave's grants concentrate

Microwave Chemical Co., Ltd. is a focused PatentsView assignee: 18 CPC subclasses with 73.3% of grants classified under B01J (Chemical OR Physical Processes, e.g. Catalysis OR Colloid CHEMISTRY; Their Relevant Apparatus). Peak complete grant year is 2020 (3 grants) versus a trough of 1 in 2023. By volume, Microwave sits between Menara Networks, Inc. and Miso Robotics, Inc..

Microwave's three-year grant acceleration

Microwave Chemical Co., Ltd. shows 4 grants in 2022–2024 against only 5 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.
