What this shows Sierra's Innovation Score is 32.2/100 (40th 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 Sierra?

Each dot is one of Sierra’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). Sierra’s own 14.3 claims/patent is at or below the 22.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Sierra's grants concentrate

Sierra Sciences, LLC is a focused PatentsView assignee: 7 CPC subclasses with 87.5% of grants classified under A61K (Preparations FOR Medical, Dental OR Toiletry Purposes). Peak complete grant year is 2024 (2 grants) versus a trough of 1 in 2016. By volume, Sierra sits between Sichuan Xingzhi Zhihui Intellectual Property Operation Co., Ltd. and Silicon Space Technology Corporation.

Sierra's three-year grant acceleration

Sierra Sciences, LLC shows 3 grants in 2022–2024 against only 3 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.
