상표 검색 및 통관을 위한 AI

Trademark clearance usually happens in stages. A quick knockout search screens out obvious conflicts. A full search then covers national and foreign registers, state registrations, and unregistered (common-law) sources such as websites, domain names, app stores and business directories. Finally, an attorney writes an opinion on the risk. AI mostly speeds up the first two stages, but its output only makes sense once you know the legal test it serves. That test is likelihood of confusion, not identity. In the United States, the Trademark Trial and Appeal Board and the courts weigh factors set out in In re E. I. du Pont de Nemours & Co. (1973). These include how similar the marks are in appearance, sound, meaning and overall commercial impression, how related the goods or services are, and the channels of trade. Search tools are built around those dimensions: Phonetic matching catches sound-alikes, such as a word spelled with K instead of C; Orthographic (spelling) matching uses edit distance and character patterns to find near spellings; Semantic matching looks for synonyms, translations and shared meaning. This matters under the doctrine of foreign equivalents, which lets a foreign word be translated before comparison; and Visual search compares logos and design marks by shape, and can be combined with the design codes that trademark offices assign to image elements. Public tools now include image search, notably the WIPO Global Brand Database and the EUIPO's search services. Commercial providers such as Corsearch and Clarivate's CompuMark sell broader searches and risk ranking. The common misconception is that a clean result means a mark is safe, or that a hit means it is blocked. A similarity score is not a probability of refusal. An attorney still weighs how strong the earlier mark is, how crowded the field is, whether the goods are really related, and how the marks are used in the market. Databases capture those facts poorly.
