Intellectual Property

Under the Exclusive License and Sublicense Agreement with Ligand, dated March 24, 2025, the Company acquired exclusive rights to a robust IP portfolio that provides material coverage for ZELSUVMI, which includes patents and patent applications covering the ZELSUVMI product and its use for treating molluscum contagiosum; trademarks; and know-how and trade secrets covering various aspects of the nitric oxide NITRICIL Technology Platform in addition to manufacturing, research, development, formulation, analytical chemistry and analytical science know-how.

There are 14 issued U.S. patents covering ZELSUVMI which are listed in the Orange Book and which are expected to expire during the time period beginning in 2026 and ending in 2035. Upon the initial approval of ZELSUVMI, we applied for 1,280 days of patent term extension (“PTE”) for the U.S. patent covering ZELSUVMI compositions. Assuming grant of the PTE application, the term of this patent may be extended from February 27, 2034, to August 30, 2037.

In addition, in certain instances, a patent’s term can be adjusted to recapture a portion of the USPTO’s delay in examining and issuing the patent, and extended to recapture a portion of the patent term effectively lost as a result of the FDA regulatory review period of the drug covered by the patent. However, as to the FDA component, the restoration period cannot be longer than five years, the total patent term including the restoration period must not exceed 14 years following FDA approval of the drug, and the extension may only apply to one patent that covers the approved drug (and to only those patent claims covering the approved drug or a method for using it). There can be no assurance that any such patent term adjustment or extension will be obtained. The duration of foreign patents varies in accordance with provisions of applicable local law, but typically is also 20 years from the earliest effective non-provisional filing date. However, the actual protection afforded by a
