What this shows Polnox's Innovation Score is 27.1/100 (22nd 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 Polnox?

Each dot is one of Polnox’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). Polnox’s own 7.8 claims/patent is at or below the 13.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Polnox's grants concentrate

Polnox Corporation is a focused PatentsView assignee: 12 CPC subclasses with 77.8% of grants classified under C10M (Lubricating Compositions ; USE OF Chemical Substances Either Alone OR AS Lubricating Ingredients IN A Lubricating Composition). Peak complete grant year is 2015 (2 grants) versus a trough of 1 in 2018. By volume, Polnox sits between Plasticolor Molded Products Inc. and PowerbyProxi Limited.

Polnox's three-year grant acceleration

Polnox Corporation shows 1 grants in 2022–2024 against only 3 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.
