Office Action

§102 §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 Objections Claims 2-14 and 16-22 are objected to because of the following informalities: the mentioned claims recite “device of Claim” which should be changed to “device of claim”. See MPEP 608.01(m) which states that each claim begins with a capital letter and ends with a period. 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: “mechanical means” in claim 9. 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 § 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.

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 text of those sections of Title 35, U.S. Code not included in this action can be found in a prior Office action. 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. Claim(s) 5, 7, 10-14 and 19 is/are rejected under 35 U.S.C. 103 as being unpatentable over US Pat Pub No 20200008549 A1 to Barber et al. (hereinafter “Barber”) in view of US Pat Pub No 20070167936 to Samain et al. (hereinafter “Samain”). Regarding claim 5. Barber discloses the device of Claim 3, but fails to disclose wherein the controller is configured to adjust a pulse duration for the generated wavelength. Samain, form a similar field of endeavor, teaches wherein the duration of the light pulse reaching the keratinous fibers may be between about 100 ps and about 1 μs, better still between about 1 ns and about 100 ns, especially greater than 5 ns, for example around 10 ns (para 0018) to treat keratinous fibers, specially hair fibers (para 0052). It would have been obvious before the filing date of the claimed invention to modify the disclosure of Barber with the teachings of Samain to provide the predictable result of treating hair. Regarding claim 7. Barber discloses the device of Claim 1, but fails to disclose wherein the generated laser beam has a pulse duration between 10 picoseconds and 50 nanoseconds. Samain, form a similar field of endeavor, teaches wherein the duration of the light pulse reaching the keratinous fibers may be between about 100 ps and about 1 μs, better still between about 1 ns and about 100 ns, especially greater than 5 ns, for example around 10 ns (para 0018) to treat keratinous fibers, specially hair fibers (para 0052). It would have been obvious before the filing date of the claimed invention to modify the disclosure of Barber with the teachings of Samain to provide the predictable result of treating hair. It is noted that “where the general conditions of a claim are disclosed in the prior art, it is not inventive to discover the optimum or workable ranges by routine experimentation.” In reAller, 220 F.2d 454, 456, 105 USPQ 233, 235 (CCPA 1955). Regarding claim 10. Barber discloses the device of Claim 1 but fails to disclose further comprising a harmonic doubler configured to generate wavelength harmonics for the generated laser beam. Samain, form a similar field of endeavor, teaches that it is known to provide a frequency doubler for brining the wavelength of the light reaching the keratinous fibers back to about 523 nm. It would have been obvious before the filing date of the claimed invention to modify the disclosure of Barber with the known teachings of Samain to provide the predictable result of bringing the wavelength of the light reaching the keratinous fibers back to about 523 nm. Regarding claim 11. Barber discloses the device of Claim 1 but fails to disclose further comprising a beam expander configured to spread the generated laser beam before it is reflected out from the optical medium and before it is applied to hair strands. Samain, form a similar field of endeavor, teaches wherein the treatment head comprise at least one lens, especially a cylindrical lens, for generating an approximately flat light beam (para 0069; which is understood to expand the laser beam at least in parts). It would have been obvious before the filing date of the claimed invention to modify the disclosure of Barber with the teachings of Samain to provide the predictable result of generating a flat light beam to treat hair. Regarding claim 12. Barber discloses the device of Claim 1 but fails to disclose further comprising a lens configured to adjust the focus the generated laser beam before it is applied to hair strands. Samain, form a similar field of endeavor, teaches providing a device for focusing the light beam emitted by the laser which allows a less powerful, and therefore less expensive, laser to be used, while still achieving an energy level sufficient to destroy the melanin selectively. (para 0062). It would have been obvious before the filing date of the claimed invention to modify the disclosure of Barber with the teachings of Samain to provide the predictable result of allowing a less powerful, and therefore less expensive, laser to be used, while still achieving an energy level sufficient to destroy the melanin selectively. Regarding claim 13. Barber discloses the device of Claim 1 but fails to disclose further comprising a beam shaping lense configured to generate a beam shape for the generated laser beam before it is applied to hair strands. Samain, form a similar field of endeavor, teaches wherein the treatment head comprise at least one lens, especially a cylindrical lens, for generating an approximately flat light beam (para 0069). It would have been obvious before the filing date of the claimed invention to modify the disclosure of Barber with the teachings of Samain to provide the predictable result of generating a flat light beam to treat hair. Regarding claim 14. Barber as modified by Samain renders obvious the device of Claim 13, wherein the beam shape is rectangular (para 0069 “treatment head, especially when the laser is rigidly connected to it, may comprise at least one lens, especially a cylindrical lens, for generating an approximately flat light beam, for example one several millimeters in length by one millimeter in width”) Regarding claim 19. Barber discloses the flat iron of Claim 17, but fails to disclose wherein the controller is configured to adjust a pulse duration for the generated wavelength. Samain, form a similar field of endeavor, teaches wherein the duration of the light pulse reaching the keratinous fibers may be between about 100 ps and about 1 μs, better still between about 1 ns and about 100 ns, especially greater than 5 ns, for example around 10 ns (para 0018) to treat keratinous fibers, specially hair fibers (para 0052). It would have been obvious before the filing date of the claimed invention to modify the disclosure of Barber with the teachings of Samain to provide the predictable result of treating hair. Regarding claim 22. The flat iron of Claim 15 but fails to disclose further comprising a cooling mechanism configured to remove heat generated by the laser beam source. Samain, form a similar field of endeavor, teaches providing cooling means for cooling the lock of hair … when the heating induced by the laser light risks damaging the hair (para 0143). It would have been obvious before the filing date of the claimed invention to modify the disclosure of Barber with the teachings of Samain to provide the predictable result of cooling the hair to prevent damaging the hair.
