According to IPStudies, over 12,000 CRISPR patent applications have been filed worldwide, falling into about 4,600 patent families. The number of issued patents is still impressive, more than 740 to date. More than half have been awarded in just two countries. Can you guess where?

China and the US, of course. Players dominating the patent landscape are the University of California and the Broad Institute – where CRISPR was respectively invented and adapted for genome editing in eukaryotes – the Chinese Academy of Sciences, the US company DuPont and the Massachusetts-based biotech firm Editas Medicine.

The struggle between UC and Broad over the standard Cas9 system is still on and is pushing the development of alternatives. CRISPR enzymes now come in approximately 50 different types, including Cpf1, C2c2,  and CasY.

The partial score at the US and the EU patent offices is 34 patents granted to the Boston team and 10 to Berkeley. To learn more, read The Scientist.
