Argument Recap – REGENXBIO Inc. v. Sarepta Therapeutics, Inc.

Last week, the Federal Circuit heard oral argument in a patent case we have been following because it attracted three amicus briefs. The case, REGENXBIO Inc. v. Sarepta Therapeutics, Inc., raises questions relating to eligibility of a genetically engineered cultured host cell that contains nucleic acid sequences from at least two different organisms spliced together into a single molecule. This case asks whether a district court erred in holding patent claims ineligible because the inventors merely “combined natural products and put them in a host cell.” Judges Dyk, Hughes, and Stoll heard the oral argument. This is our argument recap.

Late last month, the Federal Circuit issued its opinion in Dinh v. United States, a case we have been monitoring because it attracted an amicus brief.
