What this shows Beifa's Innovation Score is 21.8/100 (9th 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 Beifa?

Each dot is one of Beifa’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). Beifa’s own 1.4 claims/patent is at or below the 14.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Beifa's grants concentrate

Beifa Group Co., Ltd. is a focused PatentsView assignee: 5 CPC subclasses with 5.3% of grants classified under B43K (Implements FOR Writing OR Drawing). Peak complete grant year is 2018 (12 grants) versus a trough of 1 in 2016. By volume, Beifa sits between BOE (Hebei) Mobile Display Technology Co., Ltd. and Canadian Tire Corporation, Limited.

Beifa's three-year grant acceleration

Beifa Group Co., Ltd. shows 1 grants in 2022–2024 against only 19 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.
