 from generic drug maker Ajanta Pharma Limited (“Ajanta”) dated September 19, 2022, directed to ten of its Oxtellar XR® Orange Book patents.  Supernus’s U.S. Patent Nos. 7,722,898; 7,910,131; 8,617,600; 8,821,930; 9,119,791; 9,351,975; 9,370,525; 9,855,278; 10,220,042; and 11,166,960 generally cover once-a-day oxcarbazepine formulations and methods of treating seizures using those formulations. The FDA Orange Book lists all ten of the Company’s Oxtellar XR® patents as expiring on April 13, 2027.  On October 28, 2022, the Company filed a lawsuit against Ajanta alleging infringement of the Company’s ten Oxtellar XR® patents.  The Complaint—filed in the U.S. District Court for the District of Delaware—alleges, among other things, that Ajanta infringed the Company’s Oxtellar XR® patents by submitting to the FDA an Abbreviated New Drug Application (“ANDA”) seeking to market a generic version of Oxtellar XR® prior to the expiration of the Company’s patents. Filing its October 28, 2022 Complaint within 45 days of receiving Ajanta’s Paragraph IV certification notice entitles Supernus to an automatic stay preventing the FDA from approving Ajanta’s ANDA for 30 months from the date of the Company’s receipt of the Paragraph IV Notice Letter. On January 3, 2023, Ajanta answered the Complaint and denied the substantive allegations of the Complaint, asserting affirmative defenses that include non-infringement and invalidity. Ajanta also asserted Counterclaims seeking declaratory judgments of non-infringement and invalidity. On January

The agreement has been submitted to the applicable governmental agencies.
