What this shows Sina's Innovation Score is 41.9/100 (top 32% 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 Sina?

Each dot is one of Sina’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). Sina’s own 12.2 claims/patent is at or below the 12.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Sina's grants concentrate

Sina Robotics and Medical Innovators Co. Ltd is a focused PatentsView assignee: 5 CPC subclasses with 100% of grants classified under A61B (DIAGNOSIS; SURGERY; Identification). Peak complete grant year is 2022 (2 grants) versus a trough of 1 in 2019. By volume, Sina sits between Simex Inc. and Sioux Corporation.

Sina's three-year grant acceleration

Sina Robotics and Medical Innovators Co. Ltd shows 4 grants in 2022–2024 against only 1 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.
