What this shows Tronox's Innovation Score is 44.6/100 (top 25% 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 Tronox?

Each dot is one of Tronox’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). Tronox’s own 19.3 claims/patent is ABOVE the 15.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Tronox's grants concentrate

Tronox LLC is a focused PatentsView assignee: 21 CPC subclasses with 55.6% of grants classified under C01P (Indexing Scheme Relating TO Structural AND Physical Aspects OF Solid Inorganic Compounds). Peak complete grant year is 2016 (3 grants) versus a trough of 1 in 2015. By volume, Tronox sits between Toshiba America Business Solutions, Inc. and UI Technologies, Inc..

Tronox's three-year grant acceleration

Tronox LLC shows 5 grants in 2022–2024 against only 5 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.
