Hello, Yuyang Intellectual Property Agency will answer for you. Patent search is actually a very complicated task. If you are not a professional, it is recommended not to search by yourself, because patent search is very time-consuming. It is a very challenging and patient work that requires searching for similar or identical patents around the world. Patent searches are also divided into several different search methods. However, if you just lack a query website, it is recommended that you go to China Patent Network. Or you can entrust an agency to help you inquire, and you need to pay a certain fee.
