Ishikawa Prefecture in Japan is facing a legal dispute over the trademark rights to the 'Ruby Roman' grape variety in Korea, as domestic seed producers are challenging the trademark's validity. Despite the Patent Examination Board's decision to cancel the 'Ruby Roman' trademark in 2022, it remains officially registered, causing confusion. This situation does not affect the variety name's registration under the 'Plant Variety Protection Act' and does not necessarily impact Ishikawa Prefecture's request to cancel the 'Ruby Roman' variety name with the National Seed Resource Center.
