Our company would like to promote our "Roman Tile" products in Vietnam. In Thailand, Roman Tile is a generic name for tile with a flat shape containing one or two rolls and a disclaimer shall be applied for this term. Please confirm whether it is similar in Vietnam. If yes, we will convinct our team to promote this tile in Vietnam.
Also, please provide me with estimated cost of conducting trademark search to find who use the word "Roman Tile" whether it stand alone or combine with other words.
