II. Claims 16-22 and 38-44, drawn to a method for preventing or treating HIV-1 using the pharmacological composition of Group I, classified in class 514, subclass 2.” 14

15. Restriction Requirement The Examiner also stated that: “[n]o matter which group is elected, a further election of species is required. This application contains claims directed to the following patentably distinct species: Various peptidomimetics (see for example claims 3- 5).” The Examiner also stated that: “[n]o matter which group is elected, a further election of species is required. This application contains claims directed to the following patentably distinct species: Various peptidomimetics (see for example claims 3- 5).” 15

17. Arguments: Interstrand linkers of Formula I and II are not patentably distinct because They belong to the same genus of the compound of the formula depicted below: Formula III They belong to the same genus of the compound of the formula depicted below: Formula III 17

18. Successful Outcome The arguments overcame the species election requirement. “Applicant’s election with traverse of invention I... is acknowledged. The traversal is on the ground(s) that peptide T1249 and C34 are not patentably distinct from the elected peptide DP179; linker I and II are not patentably distinct. This is found persuasive because of applicants’ arguments.” The arguments overcame the species election requirement. “Applicant’s election with traverse of invention I... is acknowledged. The traversal is on the ground(s) that peptide T1249 and C34 are not patentably distinct from the elected peptide DP179; linker I and II are not patentably distinct. This is found persuasive because of applicants’ arguments.” 18

27. Argued in June 20, 2006 Response Obviousness –Neither reference provides any suggestion or motivation for making a thrombin variant that has two substitutions, let alone two substitutions W215A and E217A. –Claimed invention is non-obvious because of the unexpected properties. –The combination product WE has an synergy effect on reducing the release of fibrinopeptides A and B. See Tables 1 and 2 » (Fibrinogen: E217A: W215A:WE = 0.27:0.034:0.00089; Fibrin: E217A: W215A:WE = 0.15:0.053:0.0021) –Contrary to the examiner’s assertion, the combination of E217 and W215A produces a dramatically decreased, rather than enhanced, protein C activity. See Table 2 data for Protein C + TM (E217A:W215A:WE = 140:75:33).

28. Final Office Action Aug. 24, 2006: Examiner maintained rejections Enablement –“determining which of all polypeptides having at least 80% homology to SEQ ID NO: 3 have the desired activity would require undue experimentation.” Insufficient written description – Claim 1 fails to provide any functional limitations for the recited thrombin variants. Therefore, the polypeptides encompassed by the recited genus have any or no activity. Enablement –“determining which of all polypeptides having at least 80% homology to SEQ ID NO: 3 have the desired activity would require undue experimentation.” Insufficient written description – Claim 1 fails to provide any functional limitations for the recited thrombin variants. Therefore, the polypeptides encompassed by the recited genus have any or no activity. 28

29. In Final Office Action Aug. 24, 2006, Examiner maintained rejections Obviousness –The “synergistic effect is not unexpected” and that “many enzymes have allosteric sites that act synergistically in both the activation and inhibition of the enzyme.” Citing Metzler et al (2001). –“The skilled artisan would know that it is the ratio of protein C activity to fibrinogen clotting activity (PA/FC), not the absolute protein C activity, that determines whether the action of thrombin will be primarily anti- coagulation, via the activation of protein C, or procoagulation, via cleavage of thrombin*.” (*: fibrinogen) Obviousness –The “synergistic effect is not unexpected” and that “many enzymes have allosteric sites that act synergistically in both the activation and inhibition of the enzyme.” Citing Metzler et al (2001). –“The skilled artisan would know that it is the ratio of protein C activity to fibrinogen clotting activity (PA/FC), not the absolute protein C activity, that determines whether the action of thrombin will be primarily anti- coagulation, via the activation of protein C, or procoagulation, via cleavage of thrombin*.” (*: fibrinogen) 29

Comparative Data Between Cited References and the Invention (Exhibit A continued) PropertyPrimary Reference E229A (E217A) Secondary Reference W215A Invention WE PA/FC *19.11702865 32 *PA/FC here are calculated from the data shown in Tables 1 and 2. The term "PA/FC ratio" as used herein refers to the ratio of the percent of wild-type protein C activation (PA) activity remaining in a thrombin variant relative to the percent of wild-type fibrinogen clotting (FC) activity remaining in the thrombin variant. A value of PA/FC greater than 1.0 indicates that the thrombin variant has reduced procoagulant fibrinogen cleavage activity relative to the residual anticoagulant activity resulting from protein C activation.

33. Response to the Final Office Action: Vigorously Refuted Examiner’s points The life science/Biotechnology being in the area of unpredictable art, a synergistic effect cannot reasonably or necessarily be expected from allosteric sites. –McLennan reported that Hemoglobin has three allosteric sites, and their interactions are non- synergistic but are simply additive. See attached Abstract (Biochemistry and Molecular Biology International, Vol. 44, No. 1, pages 175-183, 1998). –Rao G.S. reported that Ascaris suumphosphofructokinase has two allosteric sites, one for fructose 2,6-biphosphate and one for AMP, and that their effects on the enzyme are additive and not synergistic.

34. Vigorously Refuted Examiner’s points in Response to the Final Office Action Examiner shifted the basis of motivation after Applicants had responded by pointing out that the combination of E217A and W215A produced a decreased, rather than enhanced protein C activity. if the motivation to combine the two references were really that obvious as the Examiner alleged, the Examiner would have asserted the motivation based on the skilled artisan's desire to provide an enhanced PC/PF ratio at the first place, rather than alleged “the skilled artisan's desire to provide a thrombin variant with enhanced protein C activation.

35. Successful Outcome Enablement and written description rejection were withdrawn for the following reasons. “The means by which the function of thrombin is regulated by its structure has been well characterized (Tsiang et al, 1995; Richardson et al, 2000). Therefore, it would not be undue experimentatikon for the skilled artisan to make and use the full scope of the recited thrombin variants; Applicants were in possession of their recited invention.” Enablement and written description rejection were withdrawn for the following reasons. “The means by which the function of thrombin is regulated by its structure has been well characterized (Tsiang et al, 1995; Richardson et al, 2000).

36. Successful Outcome Overcame obviousness rejection –“The extent of synergy resulting from the double W215A+E217A mutation is far greater than expected. As disclosed by Applicant’s analysis in Exhibit A, filed Jan. 18, 2007, the single mutation E217A gives a PA/FC of 19.1 (Gibbs et al; Table 1), the single mutation W215A gives a PA/FC of 170 (Arosio et al; Table 1), while Applicants’ W215A_E217A thrombin variant has a PA/FC of 2865. Such dramatic synergy is far greater than expected and, as such, the unexpected results overcome the prior obviousness rejection (MPEP 716.02(c)). For these reasons, rejections of Claims 1, 2, 6, 7, 16-18, 44 and 45 under 35 USC 103(a)... is withdrawn.
