You should be able to apply for a patent in Tianjin, right? Where? Where do you go after entering the Intellectual Property Office?

Hello:

You can submit your application at the Patent Agency of Tianjin Intellectual Property Office.

Application documents must be in duplicate, including: claims, description, abstract of the description, drawings of the description (utility models must have drawings) and other related documents.

If you want to apply for priority for your patent, you cannot submit it in person in Tianjin, but must apply to the Patent Department of the State Intellectual Property Office.

Hope the answer is helpful to you.
