We determine that neither of the two limitations identified by Petitioner requires an express construction for purposes of this Decision.

    “ApoE4+ patient with AD using tramiprosate over the Caltagirone reference, which disclosed treatment of ApoE4+ “all-comers” (containing at least one ApoE4 allele, either heterozygous or homozygous) with tramiprosate. See, e.g., Ex. 1002, 204–208. When Patent Owner responded to the Examiner by highlighting data (i.e., Figure 8 of the specification giving rise to the ’029 patent) showing a notable increase in cognitive function in patients with two ApoE4 alleles (homozygous) who were administered tramiprosate as compared to the ApoE4 “all-comers” (mixed homozygous/heterozygous population), the Examiner suggested narrowing the pending claims to treatment of ApoE4 homozygotes. Ex. 1002, 342. Patent Owner submitted amended claims requiring selection of patients for treatment who were homozygous for ApoE4, and argued: The presently amended claims . . . select only ApoE4 homozygotes for treatment with tramiprosate or a prodrug thereof, necessarily omitting ApoE4 heterozygotes from such treatment. . . . Caltagirone fails to teach or suggest a patient selection strategy that would limit tramiprosate treatment to patients having two ApoE4 alleles and, in fact, teaches away from such selection. Kong fails to contradict or overcome these deficiencies in Caltagirone. Kong does not refer to any patient selection strategy, much less one that would limit tramiprosate prodrug treatment to ApoE4 homozygotes. The Office's reliance on Kong is solely for its teaching of a tramiprosate prodrug. Thus, the combination of Caltagirone and Kong, taken under the Office’s interpretation, suggests treatment of all ApoE4+ patients with a prodrug of tramiprosate. This falls far short of suggesting the presently claimed patient selection and treatment strategy which selects only ApoE4 homozygotes for treatment and does not treat ApoE4 heterozygotes.

    “Babic ascertained that “different effects of a drug could be observed in different subpopulations of patients based on ApoE4 carrier status”” and that “drug effects in homozygous carriers could be greater than those in the heterozygous carriers and non-carriers who did not respond to the drug.” Ex. 1003 ¶ 107. As stated, this testimony does not support Petitioner’s contention that an ordinary artisan would have been motivated “to select homozygous ApoE4 carriers for treatment with any drug for which response has been correlated to ApoE4 carrier status.” See Pet. 41 (emphasis added). In particular, we find an insufficient factual basis for Petitioner’s contention that results obtained for galantamine, an acetylcholinesterase inhibitor (Ex. 1003 ¶ 105) would have motivated an ordinary artisan to replace the galantamine taught in Babic with tramiprosate (homotaurine), a GABA receptor agonist that works by a different mechanism (Ex. 1007, 582). We have also considered Dr. Ruffalo’s testimony that the ordinary artisan would have been motivated to replace Babic’s galantamine with tramiprosate as taught in Caltagirone or Val-APS as taught in Kong. Ex. 1003 ¶¶ 276–277. Dr. Ruffalo posits that Babic’s disclosures would have motivated the ordinary artisan to analyze Caltagirone’s data to ascertain if tramiprosate is more effective in homozygotes, and to replace galantamine with tramiprosate or Val-APS as taught in Kong because of their improved safety profiles as compared to galantamine, and because the replacement drugs target the underlying disease and not symptom amelioration as does galantamine. Id. Dr. Ruffalo also posits that the prior art would have imparted the following knowledge to the ordinary artisan: because the effect of tramiprosate was dependent on the required ApoE4 allele, homozygotes having the highest number of ApoE4 allele copies would derive, at the very least, as much benefit as from the drug as the heterozygotes having only one copy of the allele, and most likely the homozygotes would have the greatest therapeutic response to tramiprosate since they have the maximum number of copies of the required allele. Having done this simple assessment, A POSA would conclude that tramiprosate would be expected to exhibit a greater therapeutic effect in homozygotes and thus would have been motivated to treat homozygotes with tramiprosate, including in an oral dosage form as taught by Aisen. Id. Dr. Ruffalo further posits that the skilled artisan would have had a reasonable expectation of success in administering tramiprosate to treat homozygous ApoE4 patients because they “would almost certainly have the greatest response to the drug.” Id. ¶ 286. Patent Owner argues that the Examiner previously examined the issue of whether ApoE4 genotypes in treatment decisions should be considered during prosecution, with respect to Caltagirone, where ApoE4 genotypes were included, and Sleegers (Ex. 1002, 685, 1137), where studies led away from such inclusion.

    “We do not find Petitioner’s argument persuasive for the reasons set forth on pages 34–40 of the Preliminary Response. Most particularly, we note that the phrase “[a] chimeric antigen receptor (CAR)” occurs solely in the preamble of independent claim 24. Terms in a preamble, however, are not generally construed as limiting. See Allen Eng’g Corp. v. Bartell Indus., Inc., 299 F.3d 1336, 1346 (Fed. Cir. 2002). More specifically, “when the claim body describes a structurally complete invention such that deletion of the preamble phrase does not affect the structure or steps of the claimed invention,” the preamble is not considered a limitation. Catalina Mktg. Int’l, Inc. v. Coolsavings.com, Inc., 289 F.3d 801, 809 (Fed. Cir. 2002). In the present case, we find it plausible—if not likely—that the Examiner gave no weight to the terms in the preamble of claim 24 such that the remaining language did not expressly or implicitly require either a 32 transmembrane domain, or a “T-cell activation moiety” specific to CAR constructs. The Examiner appears to have recognized, however, that CAR constructs differ from Kalled’s antibodies at least in having a transmembrane domain as expressly recited in claims 29 and 30. See Ex. 2005, 605, 745–749 (allowing amended claims). This view is underscored by the Examiner’s decision not to reject claims 34 and 38 as anticipated by Kalled. See Ex. 2005, 604. Notably, claims 34 and 38 recite SEQ ID Nos 4–12, each of which encodes a complete CAR construct and, thus, implicitly includes a transmembrane domain.
