What this shows Suzhou's Innovation Score is 52.0/100 (top 11% 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 Suzhou?

Each dot is one of Suzhou’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). Suzhou’s own 15.2 claims/patent is at or below the 18.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Suzhou's grants concentrate

Suzhou Littelfuse OVS Co., Ltd. is a focused PatentsView assignee: 13 CPC subclasses with 61.1% of grants classified under H01H (Electric SWITCHES; RELAYS; SELECTORS; Emergency Protective Devices). Peak complete grant year is 2024 (6 grants) versus a trough of 2 in 2021. By volume, Suzhou sits between Strataca Systems Limited and Systems, Machines, Automation Components Corporation.

Suzhou's three-year grant acceleration

Suzhou Littelfuse OVS Co., Ltd. shows 13 grants in 2022–2024 against only 2 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.
