What this shows Neofect's Innovation Score is 36.1/100 (top 47% 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 Neofect?

Each dot is one of Neofect’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). Neofect’s own 7.3 claims/patent is at or below the 11.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Neofect's grants concentrate

Neofect Co., Ltd. is a focused PatentsView assignee: 13 CPC subclasses with 32.4% of grants classified under A61B (DIAGNOSIS; SURGERY; Identification). Peak complete grant year is 2022 (12 grants) versus a trough of 2 in 2018. By volume, Neofect sits between Mercury Plastics LLC and Niigata University.

Neofect's three-year grant acceleration

Neofect Co., Ltd. shows 16 grants in 2022–2024 against only 16 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.
