What this record means
The record shows that ECOSTONE was a Principal Register trademark owned by Dodge Delaware Inc., but its registration was cancelled on May 13 2016 because the owner failed to file a proper Section 8 declaration, so the mark is no longer live. The registration covered only Class 019 goods – specifically rubber flooring, rubber floor tiles and rolls, and tiles made of rubber and recycled material – and the record’s concern is limited to that narrow category of flooring products. Because the filing is cancelled, the USPTO record does not give the owner control over every use of the word “ECOSTONE” in other industries or contexts. The prosecution history shows the mark moved through normal examination, was approved for publication, and ultimately registered on Oct 6 2009 before the later cancellation; there are no entries indicating oppositions, cancellations by third parties, or other enforcement actions. I'd treat this as a moderate concern if you plan to use a similar name for flooring or related rubber products, but the risk is far lower for unrelated goods.
