What this shows Bujeon's Innovation Score is 25.0/100 (16th 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 Bujeon?

Each dot is one of Bujeon’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). Bujeon’s own 8.0 claims/patent is at or below the 14.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Bujeon's grants concentrate

Bujeon Co., Ltd. is a focused PatentsView assignee: 4 CPC subclasses with 100% of grants classified under H04R (Loudspeakers, Microphones, Gramophone Pick-ups OR Like Acoustic Electromechanical TRANSDUCERS; Deaf-aid SETS; Public Address Systems). Peak complete grant year is 2021 (5 grants) versus a trough of 1 in 2016. By volume, Bujeon sits between Bread Financial Payments, Inc. and Babcock Power Services, Inc..

Bujeon's three-year grant acceleration

Bujeon Co., Ltd. shows 5 grants in 2022–2024 against only 10 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.
