What this shows Panasonic's Innovation Score is 31.2/100 (37th 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 Panasonic?

Each dot is one of Panasonic’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). Panasonic’s own 12.5 claims/patent is at or below the 17.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Panasonic's grants concentrate

Panasonic Appliances Refrigeration Devices Singapore is a focused PatentsView assignee: 10 CPC subclasses with 93.3% of grants classified under F04B (Positive-displacement Machines FOR LIQUIDS; Pumps). Peak complete grant year is 2019 (5 grants) versus a trough of 1 in 2021. By volume, Panasonic sits between PTI Marketing Technologies Inc. and PathogenDx, Inc..

Panasonic's three-year grant acceleration

Panasonic Appliances Refrigeration Devices Singapore shows 4 grants in 2022–2024 against only 9 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.
