This case can reflect the priority of patent. . .
Priority is divided into foreign priority and domestic priority:
L) Paragraph (1) of Article 4 of the Paris Convention stipulates: "Any person or heir to the right who formally applies for the registration of an invention patent, utility model or design in any country of the Union has filed an application with the same content in other member countries of the Union within a certain period of time from the initial application date (called the priority date).
A claim for foreign priority must meet the following conditions
A the priority date must be the date of the first application in a foreign country, and the date of the second or third application cannot be used as the basis for claiming priority.
B the right of priority only applies to the contents of the first application for a patent for invention-creation.
C. The applicant who applies for the first time in a foreign country should be the same person as the applicant who applied in China before he has the right to claim priority. The same applicant includes the heir to the applicant's rights.
D an application must be filed in China within the priority period (inventions and utility models shall be filed within 12 months from the date of the first application abroad, and the design shall be filed within 6 months).
2. Paragraph 2 of Article 29 of China's Patent Law stipulates that "if an applicant files an application for a utility model or a patent for invention with the the State Council Patent Administration Department within 12 months from the date when the invention or utility model is first filed in China, he can enjoy domestic priority.
When claiming domestic priority, we should pay attention to the following issues:
A. The applicant claiming domestic priority is the same person as the applicant of the earlier application. "The same person" includes the heir or successor of the applicant.
B the provisions of domestic priority only apply to inventions or utility models, not to designs.
C like foreign priorities, domestic priorities may require one or more priorities or partial priorities.
D where domestic priority is claimed, the earlier application shall be deemed to have been withdrawn when the latter application is filed.
E. when claiming multiple domestic priorities, several items can be combined in parallel to claim domestic priorities; It is impossible to demand domestic priority on the basis of vertical interdependence.
