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 Objections Claims 1, 4-5, 12, 14-16, and 18-19 are objected to because of the following informalities: Claims 1, 4-5, 12, 15-16, and 18-19: the claims contain “is used for” and “for” language (“the first pad is used for”, “for irradiating the lips”, etc.). For consistency, this should be changed to “configured to” or “configured for” language. Claim 1: “or” should be changed to “for” (line 4). Claim 14: “consisting of but is not limited to” (line 2) should be changed to “comprising”. See MPEP 2111.03. Claim 1: “or” should be changed to “for” (line 5). Appropriate correction is required. 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. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. Claims 1-4, 6-7, and 11 are rejected under 35 U.S.C. 103 as being unpatentable over Wang et al. (CN 221752066), hereinafter ‘Wang’, in view of Peng (CN 212730739), hereinafter ‘Peng’. Quotations of the English translations of the documents are used for claim mapping. Regarding claim 1, Wang teaches a phototherapy face mask (cosmetic mask 1, Fig. 1, "The light emitting element 14 can emit light when it is electrified, as the light source of the cosmetic mask 1, so as to realize the cosmetic or phototherapy function of the cosmetic mask 1 to the facial skin"), comprising: a shell (housing body 111, Fig. 3) adapted to fit on the face of a user ("Exemplary, the mask main body 10 can be arc-shaped, which is good for the mask main body 10 to adapt the user face outline"); a first opening in the shell (observation hole 17 and viewing ports 171/172, Fig. 2) for eyes of the user ("In some embodiments, the mask body 10 may be provided with an observation hole 17 which may extend through the mask body 10. Exemplary, the viewing port 17 may include a first viewing port 171, a second viewing port 172"); a first pad arranged around the first opening (eyeshade 20, Fig. 1), the first pad is used for resting against periphery of eyes of the user to control the distance between shell and the face of the user (“it has a certain height and can isolate light, so it can effectively prevent the light from irradiating to the eye, so as to protect the eye from being damaged, so that the user can use the beauty mask 1”); and a light source assembly in the shell (light emitting elements 14, see Fig. 2) for providing phototherapy to the face of the user (“The light emitting element 14 can emit light when it is electrified, as the light source of the cosmetic mask 1, so as to realize the cosmetic or phototherapy function of the cosmetic mask 1 to the facial skin”). Wang does not specifically teach a second shell opening for the nose, or a second pad for supporting the chin. Peng teaches a combined multifunctional cosmetic mask (see abstract, Fig. 1) further comprising: a second opening in the shell or nose tip of the user (nose frame 21, Fig. 2); and a second pad installed at the bottom of the shell for supporting chin of the user (supporting cushion 33, Fig. 2). It would have been prima facie obvious before the effective filing date of the claimed invention to have modified Wang to incorporate the teachings of Peng to include a nose opening and chin pad. Doing so would allow for accommodation of the user’s nose and to separate the LED lamp and the user’s face, as recognized by Peng (“four direction supporting cushion 33 is worn by the face part contact with the face part, the LED lamp 32 and the user face between the distance, so as to increase the irradiation area of the LED lamp 32, so as to improve the use effect of the cosmetic mask”). Regarding claim 2, Wang and Peng teach the device of claim 1.
