What this shows Ulife's Innovation Score is 24.8/100 (16th 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 Ulife?

Each dot is one of Ulife’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). Ulife’s own 9.1 claims/patent is at or below the 15.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Ulife's grants concentrate

Ulife Healthcare Inc. is a focused PatentsView assignee: 5 CPC subclasses with 86.7% of grants classified under A47C (CHAIRS; SOFAS; Beds). Peak complete grant year is 2020 (5 grants) versus a trough of 1 in 2023. By volume, Ulife sits between Turntide Technologies, Inc. and University Industry Foundation, Yonsei University Wonju Campus.

Ulife's three-year grant acceleration

Ulife Healthcare Inc. shows 3 grants in 2022–2024 against only 11 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.
