What this shows Defond's Innovation Score is 44.6/100 (top 25% 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 10.8 claims/patent is at or below the 12.3 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 Electech Co., Ltd. is a focused PatentsView assignee: 31 CPC subclasses with 70% of grants classified under H01H (Electric SWITCHES; RELAYS; SELECTORS; Emergency Protective Devices). Peak complete grant year is 2020 (9 grants) versus a trough of 3 in 2018. By volume, Defond sits between Darfon Electronics (SUZHOU) Co., Ltd. and Echostar Technologies International Corporation.

Defond's three-year grant acceleration

Defond Electech Co., Ltd. shows 16 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.
