However, you still completed it on the basis of other people's patented technology!
So according to the normal procedure, you have to get the permission of the patentee before you can use it. You can earn money if you have money, hehe.
2. If we want to implement the technical scheme obtained by secondary development, it is likely to infringe the patent right of that patent, and it may be in trouble then.
The above two answers are that the patent you mentioned is a valid patent. Because not all patents published online are authorized patents, let alone valid patents, when you plan to use a patented technology, you must first determine the status of the patent: is it in the process of examination or has it been closed? Is the closed patent authorized, rejected or abandoned? If it has been authorized, is it still valid?
For patents that have been authorized and are still valid at present, the above two problems will be involved.
For the patent under review, whether it can be authorized is unknown, so there is a 50% possibility that these two issues will be involved.
Specific analysis of specific problems, hehe ... keep asking questions if you have any questions!
