Questão jurídica principal
Whether the plaintiffs' combined word/image trademark was forfeited for non-use during the grace period.
Decisão extraída
The combined mark was not used in a way that preserved its registered character; the non-use forfeiture was upheld.
Fundamentação extraída
Use of the word element alone, or separated from the image element, did not preserve the overall graphic character of the combined mark; the kennzeichnungskräftiger Kern was altered.
