What this shows Polyplus's Innovation Score is 44.9/100 (top 24% 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 Polyplus?

Each dot is one of Polyplus’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). Polyplus’s own 17.2 claims/patent is ABOVE the 15.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Polyplus's grants concentrate

PolyPlus Battery Company is a focused PatentsView assignee: 12 CPC subclasses with 100% of grants classified under H01M (Processes OR Means, e.g. Batteries, FOR THE Direct Conversion OF Chemical Energy Into Electrical Energy). Peak complete grant year is 2020 (9 grants) versus a trough of 2 in 2021. By volume, Polyplus sits between Oneplus Technology (SHENZHEN) Co., Ltd. and Radiant Opto Electronics (Suzhou) Co., Ltd..

Polyplus's three-year grant acceleration

PolyPlus Battery Company shows 15 grants in 2022–2024 against only 11 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.
