Regarding claim 19, Hanna discloses the method as discussed in claim 15. Hanna further discloses fitting the dynamic dental appliance (30) on either (i) the lower dental arch, (ii) the upper dental arch, or (iii) both the upper and lower dental arches (see Figs. 3-8 and 10; the mouth protector 30 is fitted on both the upper and lower dental arches). Claim Rejections - 35 USC § 103 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. Claim(s) 12 is/are rejected under 35 U.S.C. 103 as being unpatentable over Carrillo Gonzalez, as evidenced by Hanna. Regarding claim 12, Carrillo Gonzalez discloses the invention as discussed in claim 1. Although Carrillo Gonzalez does not explicitly disclose wherein the exerted adjustable force is in the range of from about 0.1 Newton to about 400 Newtons, it is noted that the applicant does not indicate that the claimed dimension is used for a particular purpose, solves a stated problem, or is otherwise critical (see paragraph [0061] of Applicant’s specification). Therefore, in Gardner v. TEC Syst., Inc., 725 F.2d 1338, 220 USPQ 777 (Fed. Cir. 1984), cert. denied, 469 U.S. 830, 225 USPQ 232 (1984), the Federal Circuit held that, where the only difference between the prior art and the claims was a recitation of relative dimensions of the claimed device and a device having the claimed relative dimensions would not perform differently than the prior art device, the claimed device was not patentably distinct from the prior art device, and thus it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the exerted adjustable force of Carrillo Gonzalez to be in the range from about 0.1 Newton to about 400 Newtons, as US 2011/0030704 A1 Hanna also discloses that children have an average occlusal force between 126.15 and 239 Newtons, and adults can have an occlusal force of 380-728 Newtons, see [0017] of Hanna, and thus modifying the exerted adjustable force to be in this range from about 0.1 Newton to about 400 Newtons allows the dental appliance to properly protect various user’s teeth and jaw more effectively while discouraging clenching. Claim(s) 13 and 16 is/are rejected under 35 U.S.C. 103 as being unpatentable over Carrillo Gonzalez in view of Hanna. Regarding claim 13, Carrillo Gonzalez discloses the invention as discussed in claim 1. Carrillo Gonzalez further discloses a bruxism treatment method comprising using at least one dynamic dental appliance according to claim 1 (see claim 1) installed in an individuals mouth and fitting on either the upper dental arch, the lower dental arch, or both the upper and lower dental arches to exert an adjustable force between the individual’s jaws (see Fig. 1 showing the dental appliance 1 installed in an individuals mouth on both the upper and lower dental arches and spring mechanism 53 is there to exert an adjustable force between the individuals jaws). Carrillo Gonzalez is silent on to exert an adjustable force between the individual’s jaws during clenching to resist the clenching and counter brain-drive clench stimulus. However, Hanna teaches an analogous dynamic dental appliance (30) installed in an individual’s mouth and fitted on both the upper and lower dental arches (see Figs. 3-8) to exert an adjustable force between the individual’s jaws during clenching to resist the clenching and counter brain-drive clench stimulus (see Figs. 3-8 and 11-12; spring assemblies 36 are an analogous biasing mechanism that is configured to exert an adjustable force between the individual’s jaws during clenching to resist the clenching and counter brain-drive clench stimulus, see [0066]-[0067]), providing to prevent bruxism while providing an open airway during sleep (see [0067]). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the method of Carrillo Gonzalez during clenching to resist the clenching and counter brain-drive clench stimulus as taught by Hanna to have provided an improved bruxism treatment method that prevents bruxism while providing an open airway during sleep (see [0067]). Regarding claim 16, Carrillo Gonzalez in view of Hanna discloses the method as discussed in claim 13. Although Carrillo Gonzalez in view of Hanna does not explicitly disclose wherein the exerted adjustable force is in the range of from about 0.1 Newton to about 400 Newtons, it is noted that the applicant does not indicate that the claimed dimension is used for a particular purpose, solves a stated problem, or is otherwise critical (see paragraph [0061] of Applicant’s specification). Therefore, in Gardner v. TEC Syst., Inc., 725 F.2d 1338, 220 USPQ 777 (Fed. Cir. 1984), cert. denied, 469 U.S. 830, 225 USPQ 232 (1984), the Federal Circuit held that, where the only difference between the prior art and the claims was a recitation of relative dimensions of the claimed device and a device having the claimed relative dimensions would not perform differently than the prior art device, the claimed device was not patentably distinct from the prior art device, and thus it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the exerted adjustable force of Carrillo Gonzalez in view of Hanna to be in the range from about 0.1 Newton to about 400 Newtons, as Hanna also discloses that children have an average occlusal force between 126.15 and 239 Newtons, and adults can have an occlusal force of 380-728 Newtons, see [0017] of Hanna, and thus modifying the exerted adjustable force to be in this range from about 0.1 Newton to about 400 Newtons allows the dental appliance to properly protect various user’s teeth and jaw more effectively while discouraging clenching. Claim(s) 8 is/are rejected under 35 U.S.C. 103 as being unpatentable over Kondo. Regarding claim 8, Kondo discloses the invention as discussed in claim 7. Although Kondo does not explicitly disclose wherein, in the activated position, the angle of the occlusal pads is in the range of from about 5 degrees to about 4 degrees, it is noted that the applicant does not indicate that the claimed dimension is used for a particular purpose, solves a stated problem, or is otherwise critical (see paragraph [0058] of Applicant’s specification). Therefore, in Gardner v. TEC Syst., Inc., 725 F.2d 1338, 220 USPQ 777 (Fed. Cir. 1984), cert. denied, 469 U.S. 830, 225 USPQ 232 (1984), the Federal Circuit held that, where the only difference between the prior art and the claims was a recitation of relative dimensions of the claimed device and a device having the claimed relative dimensions would not perform differently than the prior art device, the claimed device was not patentably distinct from the prior art device, and thus it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified in the activated position, the angle of the occlusal pads of Kondo to be in the range of from about 5 degrees to about 45 degrees to better protect a user’s teeth and jaws. Claim(s) 17-19 is/are rejected under 35 U.S.C. 103 as being unpatentable over Hanna. Regarding claim 17, Hanna discloses the method as discussed in claim 14. Although Hanna does not explicitly disclose wherein the exerted adjustable force is in the range of from about 0.1 Newton to about 400 Newtons, it is noted that the applicant does not indicate that the claimed dimension is used for a particular purpose, solves a stated problem, or is otherwise critical (see paragraph [0061] of Applicant’s specification). Therefore, in Gardner v. TEC Syst., Inc., 725 F.2d 1338, 220 USPQ 777 (Fed. Cir. 1984), cert. denied, 469 U.S. 830, 225 USPQ 232 (1984), the Federal Circuit held that, where the only difference between the prior art and the claims was a recitation of relative dimensions of the claimed device and a device having the claimed relative dimensions would not perform differently than the prior art device, the claimed device was not patentably distinct from the prior art device, and thus it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the exerted adjustable force of Hanna to be in the range from about 0.1 Newton to about 400 Newtons, as Hanna also discloses that children have an average occlusal force between 126.15 and 239 Newtons, and adults can have an occlusal force of 380-728 Newtons, see [0017] of Hanna, and thus modifying the exerted adjustable force to be in this range from about 0.1 Newton to about 400 Newtons allows the dental appliance to properly protect various user’s teeth and jaw more effectively while discouraging clenching. Regarding claim 18, Hanna discloses the method as discussed in claim 15. Although Hanna does not explicitly disclose wherein the exerted adjustable force is in the range of from about 0.1 Newton to about 400 Newtons, it is noted that the applicant does not indicate that the claimed dimension is used for a particular purpose, solves a stated problem, or is otherwise critical (see paragraph [0061] of Applicant’s specification). Therefore, in Gardner v. TEC Syst., Inc., 725 F.2d 1338, 220 USPQ 777 (Fed. Cir. 1984), cert. denied, 469 U.S. 830, 225 USPQ 232 (1984), the Federal Circuit held that, where the only difference between the prior art and the claims was a recitation of relative dimensions of the claimed device and a device having the claimed relative dimensions would not perform differently than the prior art device, the claimed device was not patentably distinct from the prior art device, and thus it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the exerted adjustable force of Hanna to be in the range from about 0.1 Newton to about 400 Newtons, as Hanna also discloses that children have an average occlusal force between 126.15 and 239 Newtons, and adults can have an occlusal force of 380-728 Newtons, see [0017] of Hanna, and thus modifying the exerted adjustable force to be in this range from about 0.1 Newton to about 400 Newtons allows the dental appliance to properly protect various user’s teeth and jaw more effectively while discouraging clenching. Regarding claim 19, Hanna discloses the method as discussed in claim 18. Hanna further discloses fitting the dynamic dental appliance (30) on either (i) the lower dental arch, (ii) the upper dental arch, or (iii) both the upper and lower dental arches (see Figs. 3-8 and 10; the mouth protector 30 is fitted on both the upper and lower dental arches).
