Answer: (1) Jinhua Company has obtained the right to use the patent through the implementation of the patent licensing contract. It is not the patentee and has no right to license others to use the patent without the permission of the patentee. Therefore, the company's behavior constitutes patent infringement.
(2) "Fangfang" Textile Factory did not know that the patent it implemented was not licensed by the patentee, so it did not constitute infringement.
(3) According to the provisions of the Patent Law, for infringement, the people's court can order it to stop the infringement and compensate for losses. Therefore, the People's Court has the right to order "Jinhua" Company to stop infringement and compensate "Baihua" Company for its losses. "Fangfang" company does not constitute infringement and therefore does not assume liability.
