Answer: A
What is disclosed before the application date is an existing design, and what is disclosed on the application date is not an existing design. The same design displayed by Hugo in the window of Galeries Lafayette on the Champs Elysées in France on July 14, 2019 is a case that has been made public abroad. The design for which patent rights are granted should be significantly different from existing designs or combinations of existing design features. There is no obvious difference between Li Gong's design and the Beetle's design. Zhang San’s patent application and authorization were filed with the Patent Administration Department of the State Council for the same design before the filing date of the patent involved, and were recorded in the patent documents announced after (including the filing date).
