Alnylam Pharmaceuticals said this week that the Japanese Patent Office has granted claims in a second patent application in the so-called Tuschl II patent series.
The application, No. 2006-317758, is entitled, "RNA Interference Mediating Small RNA Molecules," according to the company.
The patent "includes 38 claims broadly covering compositions, methods, uses, and systems for double-stranded RNAs having key structural elements that are widely recognized as important for the therapeutic activity of siRNAs," Alnylam said. The Japanese Patent Office granted a related set of claims in May last year, it noted.
