What this shows Mainhouse's Innovation Score is 28.3/100 (27th 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 Mainhouse?
Each dot is one of Mainhouse’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). Mainhouse’s own 2.1 claims/patent is at or below the 17.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
Where Mainhouse's grants concentrate
Mainhouse (Xiamen) Electronics Co., Ltd. is a focused PatentsView assignee: 4 CPC subclasses with 17.6% of grants classified under F21K (Non-electric Light Sources Using LUMINESCENCE; Light Sources Using ELECTROCHEMILUMINESCENCE; Light Sources Using Charges OF Combustible MATERIAL; Light Sources Using Semiconductor Devices AS Light-gen). Peak complete grant year is 2018 (6 grants) versus a trough of 1 in 2019. By volume, Mainhouse sits between Music Nomad, LLC and Medic, Inc..
Mainhouse's three-year grant acceleration
Mainhouse (Xiamen) Electronics Co., Ltd. shows 3 grants in 2022–2024 against only 2 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.
