What needs to be explained here is that patents are unique in law. If one company applies, another company cannot use it. For example, the project you want to do includes "smart home", which is already a patent of company A. Then you can only talk to one company. The bidding law stipulates that this situation can be avoided, but you can talk directly and let a company do it.
Actually, when I was reading a book, I also had a question here:
Still the above example, for example, my project includes "smart home", but the proportion of "smart home" in my project is very small (the total project is 300 million, and the smart home is 3 million). "Smart home" definitely still exists and cannot be dismantled, and it is closely related to other disciplines and cannot be dismantled. At this time, Company A is not qualified to build a 300 million project. What should we do? Is it necessary to wait until the qualification of Company A is upgraded?
In addition, if company A is qualified enough, but I don't want to find company A as the main body, but company A says that if you don't give me the main body, my smart home will not be made for you. Is this requirement legally allowed?
I never understood.
