“First, the Federal Circuit “has not hesitated to hold preambles limiting when they state an intended purpose for methods of using a compound.” Eli Lilly & Co. v. Teva Pharms. Int’l GmbH, 8 F.4th 1331, 1342 (Fed. Cir. 2021). And where, as here, the claims are directed to methods of using a compound for a specific purpose (i.e., treating a macular degeneration), and the method comprises a single step of administering that compound in an 30 effective amount, the Federal Circuit “[has] generally construed statements of intended purpose in such method claims as limiting.” Id. at 1340. Moreover, “[w]hen limitations in the body of the claim rely upon and derive antecedent basis from the preamble, then the preamble may act as a necessary component of the claimed invention.” Eaton Corp. v. Rockwell Int’l Corp., 323 F.3d 1332, 1339 (Fed. Cir. 2003); see also Eli Lilly & Co., 8 F.4th at 1341. In this case, claim 28 recites “[a] method of treating a macular degeneration, comprising administering an effective amount of a substituted C20-D1-3-retionoid to a patient in need thereof.” The preamble of “treating a macular degeneration” is necessary to understand the patients to whom the substituted C20-D1-3-retionoid should be administered; thus, it limits the claim. See Eli Lilly & Co., 8 F.4th at 1341–42 (citing Jansen v. Rexall Sundown, Inc., 342 F.3d 1329, 1332–33 (Fed. Cir. 2003)); Rapoport v. Dement, 254 F.3d 1053, 1059 (Fed. Cir. 2001) (holding the preamble to be limiting in a claim directed to “[a] method for treatment of sleep apneas comprising administration of a therapeutically effective amount of a [recited] compound . . . to a patient in need of such treatment,” because otherwise “the phrase ‘to a patient in need of such treatment’ would not have a proper antecedent basis”). Thus, we construe the preamble of claim 28 as limiting and give patentable weight to the phrase “method of treating a macular degeneration.” To the extent either party disagrees with our construction, the parties are welcome to further address this issue at trial.” slip op. at 30

“The Petition points to Mata’s express suggestion of “‘[p]harmacologic inhibition of one or more steps in the A2E synthetic pathway’ as ‘an effective treatment strategy for other macular degenerations associated with lipofuscin accumulation.’” Pet. 31 (quoting Ex. 1010, 7159) (alteration in original). The Petition, again relying on Dr. Guengerich’s testimony, further explains Mata taught that deprotonation at C-20 of retinal — involving cleavage of a carbon-hydrogen bond — was “a pre-requisite for undesirable A2E formation,” and that a skilled artisan “would have recognized that this deprotonation likely was a rate-limiting step in A2E formation” such that slowing the deprotonation “would slow A2E formation,” i.e., lower the production of a toxic reaction product. Id. at 41 (citing Ex. 1002 ¶¶ 259– 260). Moreover, although the evidence of record may suggest that, at least as of 1999, “there are no drugs on the market that contain deuterium in the molecule,” Ex. 1046, 85, left col., Petitioner has also provided evidence, for instance in the form of Dr. Calman’s testimony, that “there was significant interest in making deuterated versions of known therapeutics in order to slow rates of undesirable reactions.” Ex. 1004 ¶ 96; see also Pet. 15 (stating that “it was known before 2007 to . . . use deuterium to slow undesirable reaction”) (citing Ex. 1002 ¶ 123; Ex. 1004 ¶¶ 96–102). 18 Kushner et al., Pharmacological Uses and Perspectives of Heavy Water and Deuterated Compounds, 77 CANADIAN J.

We are persuaded, at least at this stage of the proceeding and based on the present record, that Petitioner has shown sufficiently that a skilled artisan would have had a reason to use C20-deuterated vitamin-A in the manner suggested in the Petition, with a reasonable expectation of success, based on alleged similarities between the use of deuterated compounds in the claimed method and use of such compounds to, e.g., lower production of toxic metabolites.” slip op. at 37
