First, Article 22 of the Patent Law stipulates that a patent should be novel, creative and practical. The second is that two or more people or units have jointly completed an invention. It is necessary to know whether they are willing to enjoy the same patent right. If these two conditions are met, you can apply to the relevant departments.
The right to apply for a patent for a cooperative invention-creation shall be shared by all parties. If one party does not agree to apply for a patent, the other party or parties shall not apply for a patent.
