Whose invention patent is the mobile phone? Do you have to pay the inventor a certain fee for each mobile phone now?

The existing mobile phone is composed of X patented technologies, and different mobile phones have different patent technology combinations. Of course, it can't all expire. As for whether to pay for each mobile phone, it depends on how the patent use contract is stipulated! One more thing is clear: the ownership of the patent does not belong to the inventor, but to the applicant! In the patent literature, there are two concepts. If I am the inventor of many invention patents of 10, but the research funds come from the state, the applicant is a unit, and the natural ownership is a unit. If someone wants to use it, he will pay the unit instead of the inventor. As for the reward given to me by the unit, it is another matter.
