A long-running dispute between two groups that claim to have invented the revolutionary CRISPR–Cas9 gene-editing tool is likely to remain unresolved for years to come, lawyers say — despite the US patent office’s latest decision to award key patent rights to one of the teams.
The ultimate outcome of the patent row — which began in 2016 — could mean millions of dollars in royalties for the victor, if and when CRISPR-based therapies make it to market.
