Broad RNAi Patent Granted to Allele Biotechnology In China  
2/10/2010 3:02:42 PM

Allele Biotechnology & Pharmaceuticals, a San Diego based private company with associate offices and laboratories in China and distribution channels in 30 countries, was granted a major landmark patent in China in the field of RNA interference (RNAi). The patent CN02828345.7, issued on January 20, 2010, covers compositions of DNA molecules that can be transcribed into RNAi-mediating RNA molecules, including the commonly used shRNA and miRNA-like designs. The patent also grants Allele Biotech rights to the process of introducing such DNA molecules into cells. To induce gene silencing by RNA interference, researchers often bring DNA molecules that encode interfering RNAs into cells via plasmid or viral vectors. The rights to use related technologies for the purposes of completely or partially abolishing gene functions through the mechanism of RNAi are granted to Allele Biotech.

Additional claims include methods of studying gene functions using DNA-encoded RNAi agents, or modifying gene expression profile by introducing gene expression-altering DNA molecules that will induce RNAi. The patent further protects the use of DNA-mediated RNAi in creating cell, animal models, and for curing human diseases. Allele Biotech intends to fully realize the value of this broad patent by providing opportunities to R&D centers, service providers, and reagent sellers to license at reasonable fees, so that this great technology will continue to be widely used and further developed through original research and investment.
