What this shows Tetra's Innovation Score is 47.1/100 (top 19% 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 Tetra?

Each dot is one of Tetra’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). Tetra’s own 16.2 claims/patent is ABOVE the 13.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Tetra's grants concentrate

Tetra Technologies, Inc. is a focused PatentsView assignee: 23 CPC subclasses with 60.7% of grants classified under E21B (Earth OR Rock DRILLING; Obtaining OIL, GAS, Water, Soluble OR Meltable Materials OR A Slurry OF Minerals From Wells). Peak complete grant year is 2016 (9 grants) versus a trough of 2 in 2019. By volume, Tetra sits between Sangamo Biosciences, Inc. and The Industry & Academic Cooperation in Chungnam National University (IAC).

Tetra's three-year grant acceleration

Tetra Technologies, Inc. shows 14 grants in 2022–2024 against only 15 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.
