Office Action

§103
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Claim Rejections - 35 USC § 103 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) 1, 11, and 20 is/are rejected under 35 U.S.C. 103 as being unpatentable over Uebo (JP 2003299520 A, see machine translated ver.) in view of Kim (US 20230172333 A1) and Wagner (US 20070272267 A1). Re. Claim 1, Uebo discloses a method of applying solutions to a wearer's eyelashes (Fig. 5) comprising the steps of: (1) placing a base component (10) with double adhesive tape (14; Fig. 5b; Par. 17) on a wearer's eyelid (Par. 17, Fig. 5-6 where it is placed on the bottom surface on top of a wearer’s eyelid); (2) applying a solution to the wearer's eyelashes (Par. 18); (3) placing a band component (52; Fig. 5a) on top of the wearer’s eyelashes such that the base component traps the eyelashes (51 to the surface of the base component (10) for a duration to allow the solution to effectively react with the wearer’s eyelashes (Par. 18); Wherein the method avoids application of agents which harden from liquid form into solid form to be applied concomitantly to the eyelashes (Uebo discloses in Par. 14 that double adhesive is applied and does not use a liquid adhesive. It should also be noted that instead of double adhesive tape Uebo can substitute it with a liquid adhesive but is optional). However, Uebo is silent to a coupled magnetic system and a band component having a corresponding second magnetic element on top of the wearer's eyelashes such that the band component traps the eyelashes to the surface of the base component for a duration to allow the solution to effectively react with the wearer's eyelashes; and wherein the base component has a maximum thickness of 6 mm. Uebo does disclose that the base component (52) may have metal (Par. 10-11) and the eyelashes are held between base component (10) and band component (52). Kim discloses a eyelash holding system in the same field of endeavor and further discloses a base component (111; Fig. 3-4) and a band component (112; Fig. 3-4) wherein the base component (111) has a first magnetic element (Par. 44) and the band component (112) has a second magnetic element (Par. 44). It would have been obvious to someone skilled in the art before the effective filing date to have the method of Uebo to have a coupled magnetic system and a band component having a corresponding second magnetic element on top of the wearer's eyelashes such that the band component traps the eyelashes to the surface of the base component for a duration to allow the solution to effectively react with the wearer's eyelashes as taught by Kim to provide alternative means to hold the eyelashes in place. Wagner discloses the eyelash rod in the same field of endeavor and further discloses varying sizes of eyelash perming rods (Fig. 30) where the size used by user is dependent on the user’s eyes and eyelashes (Par. 12), wherein a base component can have a thickness of 4 mm, 5 mm or 6 mm (Fig. 3; Par. 13). It would have been obvious to someone skilled in the art before the effective filing date to have the base component of Uebo and Kim to have a thickness of 6 mm as taught by Wagner as it is a design choice dependent on the user’s eye/eyelash size. Re. Claim 11, Uebo discloses a method of applying solutions to a wearer's eyelashes comprising the steps of: (1) placing a base component (10) with double adhesive tape (14; Fig. 5b; Par. 17) on a wearer's eyelid (Par. 17, Fig. 5-6 where it is placed on the bottom surface on top of a wearer’s eyelid); (2) applying a solution to the wearer's eyelashes (Par. 18); (3) placing a band component (52; Fig. 5a) on top of the wearer’s eyelashes such that the base component traps the eyelashes (51 to the surface of the base component (10) for a duration to allow the solution to effectively react with the wearer’s eyelashes (Par. 18). However, Uebo is silent to a coupled magnetic system and a band component having a corresponding second magnetic element on top of the wearer's eyelashes such that the band component traps the eyelashes to the surface of the base component for a duration to allow the solution to effectively react with the wearer's eyelashes; wherein the method does not include a step of application of adhesive to the eyelashes and wherein the base component has a maximum thickness of 6 mm. Uebo does disclose that the base component (52) may have metal (Par. 10-11) and the eyelashes are held between base component (10) and band component (52). Kim discloses a eyelash holding system in the same field of endeavor and further discloses a base component (111; Fig. 3-4) and a band component (112; Fig. 3-4) wherein the base component (111) has a first magnetic element (Par. 44) and the band component (112) has a second magnetic element (Par. 44). It would have been obvious to someone skilled in the art before the effective filing date to have the method of Uebo to have a coupled magnetic system and a band component having a corresponding second magnetic element on top of the wearer's eyelashes such that the band component traps the eyelashes to the surface of the base component for a duration to allow the solution to effectively react with the wearer's eyelashes as taught by Kim to provide alternative means to hold the eyelashes in place. As such, the combination of Uebo and Kim would provide teaching of wherein the method does not include a step of application of adhesive to the eyelashes as a magnetic coupling system is implemented taught by Kim. Wagner discloses the eyelash rod in the same field of endeavor and further discloses varying sizes of eyelash perming rods (Fig. 3) where the size used by user is dependent on the user’s eyes and eyelashes (Par. 12), wherein a base component can have a thickness of 4 mm, 5 mm or 6 mm (Fig. 3; Par. 13). It would have been obvious to someone skilled in the art before the effective filing date to have the base component of Uebo and Kim to have a thickness of 6 mm as taught by Wagner as it is a design choice dependent on the user’s eye/eyelash size. Re. Claim 20, Uebo discloses a method of applying solutions to a wearer's eyelashes comprising the steps of: (1) placing a base component (10) with double adhesive tape (14; Fig. 5b; Par. 17) on a wearer's eyelid (Par. 17, Fig. 5-6 where it is placed on the bottom surface on top of a wearer’s eyelid); (2) applying a solution to the wearer's eyelashes (Par. 18); (3) placing a band component (52; Fig. 5a) on top of the wearer’s eyelashes such that the base component traps the eyelashes (51 to the surface of the base component (10) for a duration to allow the solution to effectively react with the wearer’s eyelashes (Par. 18); and Wherein the method avoids application of agents which harden from liquid form into solid form to be applied concomitantly to the eyelashes (Uebo discloses in Par. 14 that double adhesive is applied and does not use a liquid adhesive. It should also be noted that instead of double adhesive tape Uebo can substitute it with a liquid adhesive but is optional). However, Uebo is silent to a coupled magnetic system and a band component having a corresponding second magnetic element on top of the wearer's eyelashes such that the band component traps the eyelashes to the surface of the base component for a duration to allow the solution to effectively react with the wearer's eyelashes; wherein the method does not include a step of application of adhesive to the eyelashes and wherein the base component has a maximum thickness of 6 mm. Uebo does disclose that the base component (52) may have metal (Par. 10-11) and the eyelashes are held between base component (10) and band component (52). Kim discloses a eyelash holding system in the same field of endeavor and further discloses a base component (111; Fig. 3-4) and a band component (112; Fig. 3-4) wherein the base component (111) has a first magnetic element (Par. 44) and the band component (112) has a second magnetic element (Par. 44). It would have been obvious to someone skilled in the art before the effective filing date to have the method of Uebo to have a coupled magnetic system and a band component having a corresponding second magnetic element on top of the wearer's eyelashes such that the band component traps the eyelashes to the surface of the base component for a duration to allow the solution to effectively react with the wearer's eyelashes as taught by Kim to provide alternative means to hold the eyelashes in place. As such, the combination of Uebo and Kim would provide teaching of wherein the method does not include a step of application of adhesive to the eyelashes as a magnetic coupling system is implemented taught by Kim. Wagner discloses the eyelash rod in the same field of endeavor and further discloses varying sizes of eyelash perming rods (Fig. 30) where the size used by user is dependent on the user’s eyes and eyelashes (Par. 12), wherein a base component can have a thickness of 4 mm, 5 mm or 6 mm (Fig. 3; Par. 13). It would have been obvious to someone skilled in the art before the effective filing date to have the base component of Uebo and Kim to have a thickness of 6 mm as taught by Wagner as it is a design choice dependent on the user’s eye/eyelash size. Claim(s) 2-6, 10, 12-16 is/are rejected under 35 U.S.C. 103 as being unpatentable over Uebo (JP 2003299520 A, see machine translated ver.) in view of Kim (US 20230172333 A1), Wagner (US 20070272267 A1), and Lee (KR 102606409 B1, see machine translated ver.).
