Technique has lost commercial value after researcher stopped application
Han Chunyu, a Chinese researcher who gained the spotlight for a next-generation approach to gene-editing that research groups across the world later said could not be repeated, could lose his patent for the process.
The State Intellectual Property Office notified Han and co-applicant Shen Xiao from Zhejiang University on Jan 9 that the application for his NgAgo gene-editing approach was deemed to have been withdrawn because they did not furnish documents that the office requested in July.
The patent faces the risk of being revoked within two months, according to the office.
Zheng Haifeng, a patent agent from the Hangzhou Qiushi Patent Office in Zhejiang province, said that it was the applicants’ choice to let the application be withdrawn.

Applicants can request the recovery of their application within two months if they can provide good reasons, but Zheng said he did not know whether Han and Shen would start that procedure.
Han and Shen, with two other authors, published a paper in Nature Biotechnology in May that claimed they had discovered a new gene-editing tool named NgAgo that was believed to be more efficient than the widely used CRISPR/ Cas9 approach, also known as
