What this shows Tesaro's Innovation Score is 51.8/100 (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 Tesaro?

Each dot is one of Tesaro’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). Tesaro’s own 17.6 claims/patent is ABOVE the 16.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Tesaro's grants concentrate

Tesaro, Inc. is a focused PatentsView assignee: 13 CPC subclasses with 72.2% of grants classified under A61K (Preparations FOR Medical, Dental OR Toiletry Purposes). Peak complete grant year is 2023 (7 grants) versus a trough of 1 in 2020. By volume, Tesaro sits between Tempra Technology, Inc. and The Automation Partnership (Cambridge) Limited.

Tesaro's three-year grant acceleration

Tesaro, Inc. shows 11 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.
