Wilson Sonsini Secures PTAB Institution in Five IPRs Filed for Azurity Pharmaceuticals
On November 19, 2025, Wilson Sonsini obtained a significant milestone for Azurity Pharmaceuticals, with the Patent Trial and Appeal Board (PTAB) instituting inter partes review in all five petitions the firm filed on Azurity’s behalf. The petitions challenge methods and compositions for treating chemotherapy-induced nausea and vomiting. The Board’s institution decisions found a reasonable likelihood that Azurity will prevail on at least one challenged claim in each proceeding and authorized full trials on the grounds raised. The Board’s decisions are a notable milestone in the current PTAB environment, where institution rates have tightened significantly. Three Administrative Patent Judges independently concluded the challenges were reasonably likely to succeed, and the cases will now proceed to the yearlong trial phase.
