√ 2. According to Article 9 of the Patent Law, China's patent law adopts the principle of "application first", that is, if two or more people apply for a patent for the same invention-creation, the patent right will be granted to the person who applies first.
X 3。 According to the definition of invention patent and utility model patent in Article 2 of the Patent Law, we can know that utility model patent refers to a new practical technical scheme for product shape, structure or their combination, and the invention in this case is a "new method to improve the quality and efficiency of floor processing", which obviously does not belong to utility model patent, so we cannot declare utility model patent. An invention patent refers to a new technical scheme for a product, method or its improvement, so the invention in this case belongs to a new processing technology, that is, a new method, so it conforms to the definition of an invention patent and can apply for an invention patent.
According to the examination system of utility model patent and invention patent, the examination and approval period of utility model patent authorization is shorter than that of invention, and the patent right can be obtained as soon as possible.
4. In this case, Gong Li is an electronic engineer. In his spare time, he mainly used the material conditions of his unit to develop a new technology to improve the quality and efficiency of floor processing, that is, he did not complete the above inventions by completing the tasks of his unit. According to the third paragraph of Article 6 of the Patent Law, "if an invention-creation completed by using the material and technical conditions of the entity has a contract with the inventor or designer, the ownership of the patent application right and patent right shall be stipulated", so it is possible for Gong Li to obtain the patent application right through consultation with the entity.
