The latest “Patent Law” in China introduced the patent open license
system for the first time, but there is no stipulation on the applicable conditions
in the provisions, so it has become an urgent problem to clarify the applicable
conditions of the open patent licensing system. First, it should be clear that
the subject of the application includes the patentee and the patent applicant.
Secondly, in the process of license withdrawal, the reliance interest of potential
licensees can be protected by means of advance notice withdrawal and limited
interpretation of the “patent implementation period”. Finally, on the basis of
clarifying the attributes of the open license declaration as an offer, a two-part
open license establishment path of “open-general license” is adopted to help the
system operate more efficiently in Chinese current patent trading market.
