How to apply for a patent? Is it necessary to provide physical objects?

Let me help you answer this question: 1. First of all, what patent do you want to apply for? Is it an invention? Utility model? Or design? Generally speaking, these three kinds of patents do not need to provide physical objects, inventions or utility models need to provide structural schematic diagrams of patents, and design patents need to provide six front views of physical objects of design. If there is no physical object in the design, a six-sided front view of the design must be provided. 2. According to Article 29 of the Patent Law and its detailed rules for implementation, "the administrative department for patent in the State Council may, when it deems it necessary, require the applicant for a patent for design to submit the product or model using the patent for design." At this time, you need physical objects. 3. If the patent involves the biomaterial in the invention patent, a sample of the biomaterial must be provided. For this article, we can refer to the provisions of the second and third paragraphs of Article 25 in the Patent Law and its implementing rules. I don't know if my answer satisfies you. If you have any questions you don't understand, you can consult as a local patent agency.
