In case the appeal is not filed this time, you may wait until nearly the end of the year 2017 and re-file a new application for the mark “Alpine” in Class 16 in Yemen. When the cited mark “Alpine” of Winpac is raised again, you may at that time try to invalidate its validity based on 5-year non-use in Yemen. However, if Winpac uses its mark “Alpine” with the registered goods in Class 16 in Yemen, such cancellation will not bring about a successful result.
