USPTO to Issue RXi siRNA Sequence-Specific Patents

Premium

RXi Pharmaceuticals this week said it has received notices of allowance from the US Patent and Trademark Office on patent applications, filed by Thermo Fischer Scientific and licensed to RXi, covering siRNA sequences against a number of gene targets.

Specifically, the applications cover siRNAs targeting superoxide dismutase, amyloid beta precursor protein, interleukin-1 receptor-associated kinase 4, hepatocyte growth factor receptor, and cyclin-dependent kinase inhibitor p27, RXi said.

"These sequence-specific patent applications and the ones we expect to follow add another important component to our robust intellectual property portfolio," RXi President and CEO Tod Woolf said in a statement.
