Several companies cooperate to apply for patents, how to allocate the right to use them?

Article 15 of the Patent Law clearly stipulates that if there is an agreement on the right to apply for a patent or the exercise of the patent right, such agreement shall prevail. If there is no agreement, * * * someone can exploit the patent alone or license others to exploit it by ordinary license; Where another person is licensed to exploit the patent, the royalties collected shall be distributed among the owners. Except in the circumstances specified in the preceding paragraph, the exercise of all the patent application rights or patent rights of * * * shall be subject to the consent of the owner of * * *. That is to say:

(1) If a patent application is signed in advance, it shall be handled according to the contract.

(2) If the contract is not signed in advance, it can be executed by itself, without the consent of the * * * owner and without income distribution.

(3) If a contract is not signed in advance, it can be licensed to others by general license alone, without the consent of the owner, but the income should be distributed.

(4) Anyone who exercises his rights in other ways without signing a contract in advance must obtain the consent of the * * * owner. The patent rankings are in no particular order, but the evaluation titles are in order, generally the top three.
