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.

“It is their de­ci­sion. They knew about the re­quest, but they chose not to re­spond to

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
