What this shows Defond's Innovation Score is 46.1/100 (top 22% 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 Defond?

Each dot is one of Defond’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). Defond’s own 11.9 claims/patent is at or below the 13.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Defond's grants concentrate

Defond Componets Limited is a focused PatentsView assignee: 36 CPC subclasses with 63.2% of grants classified under H01H (Electric SWITCHES; RELAYS; SELECTORS; Emergency Protective Devices). Peak complete grant year is 2020 (9 grants) versus a trough of 1 in 2015. By volume, Defond sits between Delta Tooling Co., Ltd. and Duke Manufacturing Co..

Defond's three-year grant acceleration

Defond Componets Limited shows 13 grants in 2022–2024 against only 17 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.
