Thailand’s Central Intellectual Property and International Trade (IP&IT) Court has delivered a favorable ruling for Sumitomo Rubber Industries, Ltd., a major player in the tire manufacturing industry, regarding the registration of its motorcycle tire design patent. In this case, Tilleke & Gibbins represented Sumitomo in successfully advocating for recognition of the unique design elements in the company’s motorcycle tire products. Case Overview The case revolved around Sumitomo’s two design patent applications for motorcycle tire designs, which were initially rejected by the Department of Intellectual Property (DIP) on the grounds that they were similar to prior art. Based on an examination of the design elements, primarily focusing on the tire tread patterns, the DIP’s Patent Board had concluded that Sumitomo’s designs were not sufficiently unique to warrant patent protection, as the tread patterns of the new designs were deemed too similar to one found in prior art for tire products. In response, Tilleke & Gibbins filed a complaint with the IP&IT Court on behalf of Sumitomo, seeking a revocation of the Patent Board’s decision and requesting that the court compel the DIP, as the defendant, to proceed with the registration of Sumitomo’s design patents. The complaint emphasized that the designs were novel and distinct, warranting patent protection under Thai law. Legal Strategy The firm’s legal argument focused on the interpretation of Thai patent law, particularly regarding the protection of a product’s external appearance, and emphasized that the determination of a design’s novelty must consider the product’s overall appearance rather than isolating individual features. This approach is consistent with international guidelines on design patents, which require the evaluation of novelty and distinctiveness based on how an informed user would perceive the design as a whole. While Sumitomo’s tire tread patterns may share some superficial similarities to existing designs, the overall impression
