Do I have to pay for the use of published patents?

There are two cases: 1, if it is a patent that has been publicly invalid, it can be used free of charge; 2. If it is a patent that has been made public but is still valid, it is necessary to sign an agreement with the patentee or transfer the patent.

Patent licensing, also known as patent licensing trade, refers to that the owner of patented technology or his authorized person permits others to exploit the patents owned by him in a certain way within a certain period of time and in a certain area, and collects royalties from others. Patent license only transfers the right to use the patented technology, the transferor still owns the patent, and the transferee only has the right to exploit the patented technology, but not the patent ownership. Patent licensing is a kind of licensing trade that allows licensees to use their patents within a certain range by concluding a patent licensing contract and paying royalties.

1, avoid blindly expanding the patent value-for the pre-tender estimate of patent right transfer, it should be based on the principle of being able to clinch a deal, otherwise the cooperation is likely to fail;

2. Don't make a quick decision-patent transfer is a legal procedure, so it is recommended to entrust relevant professionals (such as lawyers) to carry out relevant operations, and don't sign contracts casually;

We should put cooperation in the first place-the purpose of patent development is not only to affirm ourselves, but also to benefit society and contribute to life. A patented technology with a certain technical content and market capacity can only be technology before it is transformed into social productive forces. Therefore, industrialization is the highest standard for the benefit of society and mankind. It is also necessary to make concessions to some extent and lower some pre-tender estimate. After all, cooperation requires the sincerity of both parties.

4. Keep relevant records-keep records of the transfer process as much as possible, which is very important for subsequent problems and income distribution; Before the transfer, don't easily carry out operations such as value evaluation, especially don't easily carry out such operations according to the requirements of the other party. If it is really necessary to conduct an assessment, try to clarify the principle and proportion of the assessment fee to avoid being deceived; Don't hand over technical data and related drawings and other specific materials easily before the handover procedures are completely completed.
