The original text of the Patent Law says, "No patent right shall be granted to inventions and creations obtained or utilized in violation of laws and administrative regulations and completed by relying on genetic resources."
In other words, the acquisition and utilization channels of genetic resources violate the provisions of laws and administrative regulations. In this case, the patent right cannot be granted. Therefore, inventions involving genetic resources need to submit a genetic resources disclosure form at the time of application, indicating its acquisition method.
As long as it meets the requirements of the patent law, it can still be authorized. You can also search in the patent library. Many strains and DNA fragments are protected by national patents.
