Can tourism line (product) development enjoy the legal protection of "patent" and "trademark" in product research and development like other enterprises? Relevant persons pointed out that there is a strict definition of whether it belongs to a "patent". Patentable products must be research and development results related to professional technology and natural science. The planning, design, packaging and publicity of a tourist route by a travel agency is an intellectual activity. "Creative" design, according to international practice and relevant laws and regulations, does not belong to the scope of patent or intellectual property protection. Since "patents" and "trademarks" can't protect the development of travel agencies' routes, how can these "predecessors" who plant trees find some "psychological balance"? There is no conclusion yet. But some "attempts" can be made: legal professionals suggest that since service brands can apply for trademark protection, travel agencies can improve their social awareness of service brands by cultivating their own service brands, and at the same time "bind" newly developed routes with service brands, which can produce "protection" effects to a certain extent. The lawsuit of "Hutong Tour" in Beijing is an example.
