Do I have to pay the search report fee for the patent application for utility model? Under what circumstances?

If you ask the patent agency to help you search, they will charge you a fee. If you are in trouble, you should explain to them, win their sympathy and ask for their relief. They have the right. When I applied for a patent in 2009, I didn't spend any money searching online! I invented, found and wrote my own application materials, all of which are free. I applied to the Patent Office myself, and their staff were very enthusiastic. The state encourages inventions and creations, and they all take the initiative to reduce or exempt them. All inventions need to be searched before they can be patented. If you don't search, if someone else has applied for the patent of the same invention before you, it will be a waste of manpower and material resources. Only by searching, can we know ourselves and ourselves, and win every battle. Many things happen. Good luck! You can click on "Chui Fu Da Roast Duck" on the Internet to learn about my patent.
