What this record means
The record shows that ECOTENE is a cancelled Principal Register trademark owned by ERMENEGILDO ZEGNA CORPORATION; its registration was cancelled on March 6 2020 because the owner failed to file an acceptable Section 8 declaration. The only goods listed are “Clothing, namely, jackets” in International Class 025, so a similar name used for apparel—especially jackets—would raise the closest record‑based concern, while uses in unrelated categories fall farther from the scope shown. The record does not give the owner control over every possible use of the word ECOTENE, only over the specific clothing description recorded. There is no Supplemental Register filing to note, and the prosecution history simply tracks the normal filing, allowance, registration and the later Section 8 cancellation. The supplied history contains no oppositions, cancellations by third parties, or other enforcement actions. I'd treat this as a meaningful concern if you plan a clothing brand with a similar name.
