“These two proposed definitions of the ordinarily skilled artisan share many consistencies, for example, the types of degrees and experience such a person would have had, but differ in the number of years of experience. Petitioner proposes the ordinarily skilled artisan would have had at least five years of experience and Patent Owner proposes at least three years (which would necessarily include five years, too). Patent Owner also proposes that the ordinarily skilled artisan would have consulted a dentist, oral surgeon, prosthodontist, or periodontist with experience in dental implants and prosthetics. At this point, we find little meaningful difference between the two proposed definitions. In fact, neither does Patent Owner’s witness, Mr. Leinsing, who states that his “opinions would not change under either definition.” Ex. 2011 ¶ 40. Thus, at this stage, we accept and use Petitioner’s proposed definition of the ordinarily skilled artisan, which, unlike Patent Owner’s, does not implicate reliance on the knowledge of people other than the individual ordinarily skilled artisan. Petitioner’s definition appears to comport with the level of skill in the art reflected in the prior art of record and the ’992 patent. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (“the prior art itself [may] reflect[] an appropriate level” of the ordinary level of skill in the art) (quoting Litton Indus. Prods., Inc. v. Solid State Sys.

“Here, the first claim limitation at issue is broad, i.e., different thread pattern/profile between a definite and a temporary screw, and the Specification’s and priority applications’ disclosure is narrow and specific, asymmetric buttress style threads in a temporary screw and symmetrical threads in a definite screw (are different). Any apparent predictability in or maturity of the relevant field here must be contrasted with the fact that the Specification, considering the ’992 patent itself or any of the identified priority applications, never once even discusses the (claimed) concept of specifically differing the thread style between a temporary and a definitive screw. Any differences in thread style are not called out by the disclosure, but are described and can be discerned only in relation to the respective threads’ functionality, i.e., Fig. 75’s temporary screw 190 has buttress-style threading so it can be pulled out rather than unscrewed from the abutment; Fig. 9’s definitive screw 75 has male threads that fill the female threads of the abutment 8 for a secure permanent engagement. Ex. 1001, 15:23–30, 21:25–44, 23:3–36; Ex. 1012, 97–98, Figs. 9, 75. And, although it is possible for a single disclosed species to provide written description support for a claimed genus, “a sufficient description of a genus . . . requires the disclosure of either a representative number of species falling within the scope of the genus or structural features common to the members of the genus so that one of skill in the art can ‘visualize or recognize’ the members of the genus.” Ariad, 598 F.3d at 1350; see also Synthes USA, LLC v. Spinal Kinetics, Inc., 734 F.3d 1332, 1344 (Fed. Cir. 2013). That does not appear to be the case here—the present record does not support that the described asymmetrical buttress, serrated style of different temporary screw threading (relative to that of the definitive screw and regardless of the direction of the threads for rotation) is sufficiently representative of the genus’s “different” thread patterns/profiles. See, e.g., Ex. 1006 (a buttress style thread does not function the same as a buttress reverse or 75º joint profile or rounded, or trapezoidal thread).” slip op. at 30

Thus, the evidence of record shows the ’791 patent recognizes a broad understanding of a “modified PH20 polypeptide” as encompassing PH20 sequences from a variety of different mammalian species, with or without precursor or signal sequences, with or without post-translational modifications, and with up to 150 amino acid replacements. The express definition of “modified PH20 polypeptide” in the ’791 patent permits up to 150 amino acid replacements but only “so long as the resulting modified PH20 polypeptide exhibits hyaluronidase activity.” Ex. 1001, 47:9–11. That is, the provided definition of “modified PH20 polypeptide” in the ’791 patent expressly requires some hyaluronidase activity. On the current record, we therefore adopt the definition for “modified PH20 polypeptide” as recited in the ’791 patent to encompass polypeptides with some hyaluronidase activity. We determine that we need not expressly construe any other claim terms for the purpose of deciding whether to institute post-grant review. See Nidec Motor Corp. v.

“As we noted, on the current record claim 1 is reasonably interpreted to encompass PH20 polypeptides with some hyaluronidase activity. But even if we were to find that immunization using PH20 polypeptide as a contraceptive antigen serves to satisfy the utility requirement for the instant claims, there is a similar concern as to whether modified PH20 polypeptides with significant differences from the native protein as encompassed by claim 1 would maintain the antigenic determinants necessary to function as contraceptives. See Ex. 1003 ¶ 122. That the modified PH20 polypeptides would be homogenous in function is contradicted both by evidence in the ’791 patent itself and by Dr. Hecht and Dr. Parker. The ’791 patent discloses synthesis of 6,753 single amino acid mutations in residues 1‒447 of SEQ ID NO: 3. See Ex. 1001, 199:15–200:34. The ’791 patent teaches that just under 10% of these mutations, i.e. over 600, “exhibit activity that is increased compared to wildtype.” Id. at 233:1–2. Appendix A of Dr. Hecht’s Declaration shows 3,380 of these mutations were inactive, or 57.13%. See Ex. 1003, Appendix A-1, 171. Thus, the ’791 patent evidences that even when only a single mutation is made in the PH20 polypeptide, that single mutation is more likely than not to alter the structure in such a way as to inactivate the hyaluronidase activity found in the native PH20 polypeptide. On this record, Dr. Hecht persuasively demonstrates that when the full scope of claim 1 is addressed, which includes not just single mutations in the PH20 polypeptide, but also multiple mutations, there is no expectation of structural homogeneity, stating that “[i]ntroducing multiple amino acid changes simultaneously . . . could prevent the folding of sequences into secondary structures and structural motifs and can destabilize those structures if they do form.” Ex. 1003 ¶ 59. Dr. Hecht notes that claim 1 allows “up to 21 changes, with each additional change (except at position 309) being to any of 19 alternative amino acids. But the up to 21 changes also can be at any of 433 different positions.” Id. ¶ 129. Dr. Park calculates that the number of distinct polypeptides that meet the claimed criteria “is extremely large by all accounts, ranging from 1049 to 1060 distinct polypeptides.” See Ex. 1004 ¶ 161. Dr. Hecht characterizes the number of possible mutations as “astronomical in size.” Ex. 1003 ¶ 134.” slip op. at 20

“Every patent must describe an invention. It is part of the quid pro quo of a patent.” Ariad, 598 F.3d at 1345. Ariad explains that for generic claims the question may still remain whether the specification, including original claim language, demonstrates that the applicant has invented species sufficient to support a claim to a genus. The problem is especially acute with genus claims that use functional language to define the boundaries of a claimed genus. In such a case, the functional claim may simply claim a desired result, and may do so without describing species that achieve that result. But the specification must demonstrate that the applicant has made a generic invention that achieves the claimed result and do so by showing that the applicant has invented species sufficient to support a claim to the functionally-defined genus. Id. at 1349. Ariad explains “that an adequate written description requires a precise definition, such as by structure, formula, chemical name, physical properties, or other properties, of species falling within the genus sufficient to distinguish the genus from other materials.” Id. at 1350. Ariad also held that functional claim language can meet the written description requirement when the art has established a correlation between structure and function. . . . But merely drawing a fence around the outer limits of a purported genus is not an adequate substitute for describing a variety of materials constituting the genus and showing that one has invented a genus and not just a species.

See Ex. 1006, code (57), 7:7–26, 8:19–29. For the policy teachings, Petitioner relies upon Beaumont’s “content provider DNS server that directs requests (traffic) according to a preference table (policy).” Pet. 15–16 (citing Fig. 1, ¶¶ 6, 17, 23). Petitioner also asserts that the Beaumont-Hasan GUI would enable an administrator to set policies for a selected content delivery server to allow setting server preferences and rules. Id. at 17–18 (citing, inter alia, Ex. 1007 ¶¶ 76–77). In support, Dr. Lin testifies that: The Beaumont-Hasan GUI would enable an administrator to select a content delivery server (e.g., in Japan) and set policies for that server. Hasan, 8:30–36, 10:25–34, 10:53–67; Beaumont, [0031]. For example, given the description in Hasan, selecting a server would bring up a menu enabling an administrator to assign the preferences shown in Fig. 3 of Beaumont. Hasan, 10:25–34; Beaumont, Figs. 2, 3, [0029]–[0031]. A POSITA would thus have recognized the combined GUI to “support[] the setting of said at least one policy using a decision tree representing rules” because it is presented in a “familiar tree structure” and would allow users to set server preferences and rules. Ex. 1003 ¶ 77 (emphasis added). Beaumont provides support for Dr. Lin’s testimony. Beaumont discloses that “rules such as selecting one [a server] based on user preferences can be used . . . [f]or example, a preference number can be assigned to each content delivery server and a destination domain.” Ex. 1007 ¶ 31. Beaumont further states that “FIG. 3 shows an illustrative example of incorporating preference numbers in a column.” Id. Thus, contrary to Patent Owner’s arguments, Beaumont discloses that rules or policies, represented by the preference number, are represented in the table shown in Figure 3 of Beaumont. Dr. Lin also testifies that in the Beaumont-Hasan combination “the GUI supports the setting of” policy is taught. Ex. 1003 ¶ 77. Hasan provides support that service policies can be modified by the use of a GUI. See Ex. 1006, 8:30–36, 10:25–34, 10:53–67. Accordingly, in the combination of Beaumont and Hasan, wherein the preference database is replaced by the GUI decision tree, Petitioner has provided sufficient evidence at this juncture that the combination of Beaumont and Hasan teaches that the GUI obtains a policy, the preference number, for the direction of network traffic, where the GUI supports the setting of the policy using a decision tree representing rules.” slip op. at 19

In its Reply, Petitioner still does not provide an articulated reason for placing user profile selection buttons, labeled with user names, within Horn’s panes 2601 or 2602. Reply 12–14. Although Horn does describe personalized profile, Petitioner points to no disclosure of Horn as to how a user would have selected his or her own profile from among a plurality of user profiles. Petitioner presents no reason for placing these user profile selection buttons, labeled with user names, gleaned from or suggested by Baumgartner, within either pane 2601 or pane 2602 in Horn’s workspace view. Further, pane 2602 contains “a list of all collections defined by MFS and the user,” and pane 2601 lists the source examined by the user to create his or her collections. Ex. 1005, 19:41–46. That disclosure suggests the contents of panes 2601 and 2602 are tied to one particular user.

“The test for sufficiency of a written description under 35 U.S.C. § 112 is whether the earlier application’s disclosure “reasonably conveys to those skilled in the art that the inventor had possession of the claimed subject matter as of the filing date.” Ariad Pharms., Inc. v. Eli Lilly & Co., 598 F.3d 1336, 1351 (Fed. Cir. 2010) (en banc). The specification must “clearly allow persons of ordinary skill in the art to recognize that [the inventor] invented what is claimed.” Id. The Court of Appeals for the Federal Circuit has explained: One shows that one is “in possession” of the invention by describing the invention, with all its claimed limitations, not that which makes it obvious. Id. (“[T]he applicant must also convey to those skilled in the art that, as of the filing date sought, he or she was in possession of the invention.
