Office Action

§102 §103 §112
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 . Drawings The drawings are objected to because all of the lead lines, reference numerals, and drawing outlines in figs. 1-8 are faded and dotted. Every line must be durable, clean, black, sufficiently dense and dark, and uniformly thick and well-defined. Additionally, the weight of all lines must be heavy enough to permit adequate reproduction. See 37 C.F.R. 1.84(l). Furthermore, the drawings are objected to because figs. 2 and 7 contain an assembly having a plurality of parts, some form of connection to indicate that all of the parts are part of the same assembly is missing. A connecting axis or bracket is needed to shows that the plurality of parts are part of the same assembly. See 37 C.F.R. 1.84(h)(1). Corrected drawing sheets in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. Any amended replacement drawing sheet should include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. The figure or figure number of an amended drawing should not be labeled as “amended.” If a drawing figure is to be canceled, the appropriate figure must be removed from the replacement sheet, and where necessary, the remaining figures must be renumbered and appropriate changes made to the brief description of the several views of the drawings for consistency. Additional replacement sheets may be necessary to show the renumbering of the remaining figures. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either “Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance. Specification Applicant is reminded of the proper language and format for an abstract of the disclosure. The abstract should be in narrative form and generally limited to a single paragraph on a separate sheet within the range of 50 to 150 words in length. The abstract should describe the disclosure sufficiently to assist readers in deciding whether there is a need for consulting the full patent text for details. The language should be clear and concise and should not repeat information given in the title. It should avoid using phrases which can be implied, such as, “The disclosure concerns,” “The disclosure defined by this invention,” “The disclosure describes,” etc. In addition, the form and legal phraseology often used in patent claims, such as “means” and “said,” should be avoided. The abstract of the disclosure is objected to because it contains phrases that are implied (i.e., the term “present disclosure discloses” in line 1 of the abstract). Correction is required. See MPEP § 608.01(b). The disclosure is objected to because of the following informalities: the specification includes section headings which are bolded. Section headings are required to be in all upper case font with no bold text. See MPEP 37 C.F.R. 1.154(c). Claim Objections Claims 1 and 8 are objected to because of the following informalities: In claim 1, lines 8-9, the term “a breather assembly (200), which is provided with an air inlet channel (210) and a second air outlet channel (220) which are spaced from each other” is suggested to be changed to --a breather assembly (200), the breather assembly is provided with an air inlet channel (210) and a second air outlet channel (220), the air inlet channel (210) and the second air outlet channel (220) are spaced from each other-- in order to clarify the claim. In claim 8, line 3, the term “the eyes” is suggested to be changed to --a pair of eyes-- in order to clarify the claim. In claim 8, line 4, the term “the nose and mouth” is suggested to be changed to --a nose and a mouth-- in order to clarify the claim. Appropriate correction is required. Claim Interpretation The following is a quotation of 35 U.S.C. 112(f): (f) Element in Claim for a Combination. – An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof. The following is a quotation of pre-AIA 35 U.S.C. 112, sixth paragraph: An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof. The claims in this application are given their broadest reasonable interpretation using the plain meaning of the claim language in light of the specification as it would be understood by one of ordinary skill in the art. The broadest reasonable interpretation of a claim element (also commonly referred to as a claim limitation) is limited by the description in the specification when 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is invoked. As explained in MPEP § 2181, subsection I, claim limitations that meet the following three-prong test will be interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph: (A) the claim limitation uses the term “means” or “step” or a term used as a substitute for “means” that is a generic placeholder (also called a nonce term or a non-structural term having no specific structural meaning) for performing the claimed function; (B) the term “means” or “step” or the generic placeholder is modified by functional language, typically, but not always linked by the transition word “for” (e.g., “means for”) or another linking word or phrase, such as “configured to” or “so that”; and (C) the term “means” or “step” or the generic placeholder is not modified by sufficient structure, material, or acts for performing the claimed function. Use of the word “means” (or “step”) in a claim with functional language creates a rebuttable presumption that the claim limitation is to be treated in accordance with 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. The presumption that the claim limitation is interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is rebutted when the claim limitation recites sufficient structure, material, or acts to entirely perform the recited function. Absence of the word “means” (or “step”) in a claim creates a rebuttable presumption that the claim limitation is not to be treated in accordance with 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. The presumption that the claim limitation is not interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is rebutted when the claim limitation recites function without reciting sufficient structure, material or acts to entirely perform the recited function. Claim limitations in this application that use the word “means” (or “step”) are being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, except as otherwise indicated in an Office action. Conversely, claim limitations in this application that do not use the word “means” (or “step”) are not being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, except as otherwise indicated in an Office action. This application includes one or more claim limitations that do not use the word “means,” but are nonetheless being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, because the claim limitation(s) uses a generic placeholder that is coupled with functional language without reciting sufficient structure to perform the recited function and the generic placeholder is not preceded by a structural modifier. Such claim limitation(s) is/are: the limitation “a clamping structure is arranged between the second connector (204) and the air tube (202), and the second connector (204) is detachably connected with the air tube (202) through the clamping structure” (claim 6, lines 1-3, the term “structure” is a generic placeholder and the function is “clamping” and “the second connector (204) is detachably connected with the air tube (202) through the clamping structure”). Because this/these claim limitation(s) is/are being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, it/they is/are being interpreted to cover the corresponding structure described in the specification as performing the claimed function, and equivalents thereof. If applicant does not intend to have this/these limitation(s) interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, applicant may: (1) amend the claim limitation(s) to avoid it/them being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph (e.g., by reciting sufficient structure to perform the claimed function); or (2) present a sufficient showing that the claim limitation(s) recite(s) sufficient structure to perform the claimed function so as to avoid it/them being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 2-7 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor, or for pre-AIA the applicant regards as the invention. Regarding claim 2, the limitation “the other end” (line 4) lacks proper antecedent basis. Regarding claim 2, the limitation “a side wall” (line 7) is unclear as to what the structural relationship between the diving mask and the side wall is. Any remaining claims are rejected for their dependency on a rejected base claim. Claim Rejections - 35 USC § 102 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 the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. Claims 1-5 and 8-10 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Le Gall (2022/0135193).

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 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. Claims 6-7 are rejected under 35 U.S.C. 103 as being unpatentable over Le Gall (2022/0135193) in view of Um (KR 102314961). Regarding claims 6-7, Le Gall fails to disclose a clamping structure is arranged between the second connector and the air tube, and the second connector is detachably connected with the air tube through the clamping structure and the clamping structure comprises a hook arranged on the air tube and a mounting hole formed in the second connector; and a hook portion of the hook is accommodated in the mounting hole. However, Um teaches a clamping structure (portion of 172 on 170 in fig. 13 and portion 164 of air tube comprising 164 in fig. 7) is arranged between a second connector (170, fig. 7) and the air tube (air tube comprising 164, fig. 7), and the second connector is detachably connected with the air tube through the clamping structure and the clamping structure comprises a hook (hook on 164, figs. 5-8 and 13-15) arranged on the air tube and a mounting hole (172, fig. 13) formed in the second connector (170); and a hook portion of the hook is accommodated in the mounting hole (see figs. 5-8 and 13-15, paragraphs 0052-0053, 0056, 0060-0061). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the second connected of Le Gall and the air tube of Le Gall to be detachably connected as taught by Um for the purpose of providing a connection that would allow for ease of removal, replacement and cleaning of parts (see paragraphs 0052-0053, 0056, 0060-0061 of Um). Claims 6-7 are rejected under 35 U.S.C. 103 as being unpatentable over Le Gall (2022/0135193) in view of Hsu (2016/0107734). Regarding claims 6-7, Le Gall fails to disclose a clamping structure is arranged between the second connector and the air tube, and the second connector is detachably connected with the air tube through the clamping structure and the clamping structure comprises a hook arranged on the air tube and a mounting hole formed in the second connector; and a hook portion of the hook is accommodated in the mounting hole. However, Hsu teaches a clamping structure (portion of 33 comprising corresponding mounting hole for accommodating 41 and 42, and portion of 10 comprising 41 and 42, see fig. 3) is arranged between a second connector (30, fig. 3) and the air tube (10), and the second connector is detachably connected with the air tube through the clamping structure and the clamping structure comprises a hook (41 and 42) arranged on the air tube and a mounting hole (hole corresponding to 41 and 42, fig. 3) formed in the second connector; and a hook portion of the hook is accommodated in the mounting hole (see figs. 3-5, paragraph 0028). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the second connected of Le Gall and the air tube of Le Gall to be detachably connected as taught by Hsu for the purpose of providing a connection that would allow for ease of removal, replacement and cleaning of parts (see paragraph 0028 of Hsu). Claim 10 is rejected under 35 U.S.C. 103 as being unpatentable over Le Gall (2022/0135193) in view of Lin (CN 106428476). Regarding claim 10, Le Gall discloses that the mask assembly comprises a frame (6, fig. 1, paragraphs 0048-0056), but fails to specifically disclose a mask main body, and a shell; the breather assembly is connected with the frame; the frame is enclosed with the mask main body to form the first air outlet channel and the accommodating cavity; the frame is connected with the shell; and the mask main body is sandwiched between the frame and the shell. However, Lin teaches a frame (7, fig. 1, paragraph 0038), a mask main body (14, paragraph 0038 and see the annotated-Lin fig. 1 above), and a shell (8, fig. 1, paragraph); a breather assembly (4 and 5, fig. 1) is connected with the frame (figs. 1-7); the frame is enclosed with the mask main body to form the first air outlet channel and an accommodating cavity (see fig. 2, as shown the first air outlet channel and accommodating cavity comprises an air outlet channel that is defined by the shell and the mask main body, see outlet in mask where air leaves the mask to 51, see figs. 2-7, paragraphs 0038-0039 and 0043); the frame is connected with the shell (see figs. 1-7); and the mask main body is sandwiched between the frame and the shell (see figs. 1-7 and paragraphs 0038-0054). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the mask of Le Gall to have the frame, shell and main body as taught by Lin for the purpose of providing an alternative mask construction that would allow air to be inhaled and exit through the breather assembly of Le Gall (see paragraphs 0038-0039 and 0043 of Lin). Claim 10 is rejected under 35 U.S.C. 103 as being unpatentable over Le Gall (2022/0135193) in view of Caprice (2016/0297505). Regarding claim 10, Le Gall discloses that the mask assembly comprises a frame (6, fig. 1, paragraphs 0048-0056), but fails to specifically disclose a mask main body, and a shell; the breather assembly is connected with the frame; the frame is enclosed with the mask main body to form the first air outlet channel and the accommodating cavity; the frame is connected with the shell; and the mask main body is sandwiched between the frame and the shell. However, Caprice teaches a frame (12, fig. 1, paragraphs 0090-0100), a mask main body (40, fig. 2, paragraph 0100-0103), and a shell (10, fig. 2, paragraphs 0090, 0093-0095); a breather assembly (20, fig. 2, paragraphs 0095-0099) is connected with the frame (see figs. 1-2); the frame is enclosed with the mask main body to form the first air outlet channel and the accommodating cavity (the first air channel is formed by 92 and 200, see fig. 9, paragraphs 0116-0122); the frame is connected with the shell; and the mask main body is sandwiched between the frame and the shell (see figs. 1-9 and paragraphs 0090-0121). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the mask of Le Gall to have the frame, shell and main body as taught by Caprice for the purpose of providing an alternative mask construction that would allow air to be inhaled and exit through the breather assembly of Le Gall (see paragraphs 0095-0099 of Caprice).
