Legal analysis: (1) Geographical indications prove the origin of products. Products using geographical indications must be produced in the area marked by them. So geographical indications are named after place names. According to international practice, geographical names that can be used as geographical indications include: local administrative divisions, specific locations and other elements. (2) Geographical indications prove the special quality of products. Products using geographical indications must not only be produced in the marked area, but also the quality or characteristics of the products depend entirely or mainly on local natural factors or human factors. Geographical indications shall not be used for products whose quality or characteristics have nothing to do with geographical environment or have little to do with it.

Legal basis: Article 16 of the Trademark Law of People's Republic of China (PRC) contains geographical indications of goods. If the goods do not originate from the area marked by the marks and mislead the public, they shall not be registered and prohibited from being used; However, the registration in good faith continues to be effective.

The geographical indications mentioned in the preceding paragraph refer to the indication that a commodity originates from a certain region, and the specific quality, reputation or other characteristics of the commodity are mainly determined by natural factors or human factors in the region.
