Kyle Bass IPR petition against Lialda granted for review of U.S. Patent No. 6,773,720
From the National Law Review:
After filing over thirty petitions for Inter Partes Review of Orange Book-listed patents for various drugs, Kyle Bass and his Coalition for Affordable Drugs finally has made it over the first hurdle. The USPTO Patent Trial and Appeal Board (PTAB) decided to institute IPR proceedings against U.S. Patent No. 6,773,720, which is listed in Orange Book for Lialda®. This is bad news for Shire, since this is the only Orange Book-listed patent for Lialda®, and also bad news for pharmaceutical companies who hoped Kyle Bass would get discouraged and stop his campaign again pharmaceutical patents. -
One notes that not all of Bass's petitions have been denied. Some are pending.
