What this shows Tata's Innovation Score is 41.1/100 (top 34% 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.

Where Tata's grants concentrate

Tata Chemicals Limited is a focused PatentsView assignee: 14 CPC subclasses with 50% of grants classified under C01P (Indexing Scheme Relating TO Structural AND Physical Aspects OF Solid Inorganic Compounds). Peak complete grant year is 2022 (4 grants) versus a trough of 1 in 2020. By volume, Tata sits between Tango Therapeutics, Inc. and Telepresence Technologies, LLC.

Tata's three-year grant acceleration

Tata Chemicals Limited shows 4 grants in 2022–2024 against only 2 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.
