‚As part of the ANDA process, a generic manufacturer must make a certification addressing each patent identified in the Orange Book pertaining to its drug. 21 U.S.C. § 355(j)(2)(A)(vii). Specifically, the generic manufacturer must select one of four alternatives permitting use of the patented product or process: … (III) the patent is set to expire on a certain date [referred to as a Paragraph III certification]; or (IV) the patent is invalid or will not be infringed by the manufacture, use or sale of the generic drug. 21 U.S.C. § 355(j)(2)(A)(vii) [referred to as a Paragraph IV certification]. … If a generic manufacturer wishes to seek FDA approval for a use not covered by a method-of-use patent for a listed drug, it must make a “section viii statement”. 21 U.S.C. § 355(j)(2)(A)(viii). Along with the Section viii statement, the generic manufacturer must submit a proposed label to the FDA that does not contain the patented method of using the listed drug. When considering approval of these requests for a use not covered by a patent, the FDA relies on the applicable patent's use code narrative to determine the scope of the patented method [as discussed below]’. Novo, 601 F.3d at 1361.

The Supreme Court's ruling in Chevron USA, Inc. v. Natural Resources Defense Council, Inc., 467 US 837 (1984), set forth the legal test for determining whether to grant deference to a government agency's interpretation of its own statutory mandate. In a subsequent decision the Supreme Court summarized Chevron deference by stating ‘[w]hen a statute speaks clearly to the issue at hand we” must give effect to the unambiguously expressed intent of Congress”, but when the statute “is silent or ambiguous” we must defer to a reasonable construction by the agency charged with its implementation’.
