What this shows Sherritt's Innovation Score is 32.7/100 (42nd 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 Sherritt?

Each dot is one of Sherritt’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). Sherritt’s own 32.7 claims/patent is ABOVE the 7.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Sherritt's grants concentrate

Sherritt International Corporation is a focused PatentsView assignee: 7 CPC subclasses with 83.3% of grants classified under C22B (Production AND Refining OF Metals ; Pretreatment OF RAW Materials). Peak complete grant year is 2019 (2 grants) versus a trough of 1 in 2020. By volume, Sherritt sits between Shenzhen Zhouwu Technology Co., Ltd. and Shooting Edge Technology, LLC.

Sherritt's three-year grant acceleration

Sherritt International Corporation shows 1 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.
