ECOTANE

What this record means

The record shows that ECOTANE is a cancelled Principal Register trademark owned by T2 Laboratories Inc.; its registration was cancelled on March 30 2012 because the owner failed to file an acceptable Section 8 declaration, and the mark is now dead. The registration covered only “performance additive for motor fuel” in International Class 001, so a later use of ECOTANE for fuel additives or similar automotive chemicals would be the closest area of concern, while uses in unrelated fields such as cosmetics or software fall farther from the scope shown. The record does not give T2 Laboratories control over every possible use of the word ECOTANE, just the specific goods listed. The prosecution history shows the mark was granted on the Principal Register in 2001, renewed once under Section 8 in 2007, and then cancelled in 2012; no opposition or cancellation proceedings appear in the file. I'd treat this as a meaningful concern if you plan to market a fuel‑additive product under the same name.
