What this shows Fidelix's Innovation Score is 47.7/100 (top 18% 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 Fidelix?

Each dot is one of Fidelix’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). Fidelix’s own 13.5 claims/patent is ABOVE the 13.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Fidelix's grants concentrate

Fidelix Co., Ltd. is a focused PatentsView assignee: 8 CPC subclasses with 73.3% of grants classified under G11C (Static Stores). Peak complete grant year is 2016 (4 grants) versus a trough of 1 in 2017. By volume, Fidelix sits between Fast Retailing Co., Ltd. and Fos4x GMBH.

Fidelix's three-year grant acceleration

Fidelix Co., Ltd. shows 4 grants in 2022–2024 against only 0 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.
