What this shows Littelfuse's Innovation Score is 34.3/100 (47th 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 Littelfuse?

Each dot is one of Littelfuse’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). Littelfuse’s own 14.9 claims/patent is ABOVE the 13.1 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Littelfuse's grants concentrate

Littelfuse Electronics (Shanghai) Co., Ltd. is a focused PatentsView assignee: 14 CPC subclasses with 57.1% of grants classified under H01C (Resistors). Peak complete grant year is 2019 (4 grants) versus a trough of 1 in 2022. By volume, Littelfuse sits between Links Medical Products Incorporated and Lixin County Minghang Magnetic Soft Screen Door Co., Ltd..

Littelfuse's three-year grant acceleration

Littelfuse Electronics (Shanghai) Co., Ltd. shows 3 grants in 2022–2024 against only 4 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.
