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:
Claim limitation “component” in claims 1 has/have been interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, because it uses/they use a generic placeholder “component" coupled with functional language “…configured to correct for spherical aberration caused by mismatch in refractive index…” without reciting sufficient structure to achieve the function. Furthermore, the generic placeholder is not preceded by a structural modifier. A review of the specification shows that, although it is not clear, the following appears to be the corresponding structure described in the specification for the 35 U.S.C. 112, sixth paragraph limitation: The limitation “…configured to correct for spherical aberration…" has been described in Page 4 cited: “…The spherical aberration can also be corrected in several different ways. In one configuration, the one or more optical elements includes a lens with an adjustable correction collar to correct for spherical aberration within the sample at the target location. Alternatively, the one or more optical elements may include a lens with a fixed correction for spherical aberration within the sample at the target location. Alternatively still, the one or more optical elements can include a lens and a phase plate configured to correct for spherical aberration within the sample at the target location. Yet another alternative is that the one or more optical elements includes a combination of lenses configured to introduce a spherical aberration in the laser light which is partially or wholly cancelled by spherical aberration caused by mismatch in refractive index at the surface of the sample. Yet another alternative is that the one or more optical elements includes an adaptive optical element configured to correct for spherical aberration within the sample at the target location. The adaptive optical element (or active optical element) can include a spatial light modulator (SLM). Examples of spatial light modulators include liquid crystal SLMs such as liquid crystal on/over silicon SLMs (LCOS SLMs). Other examples include mirror-based adaptive optical element such as digital micro-mirror devices / deformable mirror devices. Sometimes these mirror based devices may also be referred to as mirror based SLMs…”.
Claim limitation “drive mechanism” in claims 1 has/have been interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, because it uses/they use a generic placeholder “mechanism" coupled with functional language “…configured to move…” without reciting sufficient structure to achieve the function. Furthermore, the generic placeholder is preceded by an insufficient structural modifier “drive”. A review of the specification shows that, although it is not clear, the following appears to be the corresponding structure described in the specification for the 35 U.S.C. 112, sixth paragraph limitation: The limitation “…drive mechanism…" has been described in Page 7 cited: “…a mechanical drive mechanism is provided for moving the sample holder and/or one or more of the optical elements based on the measured tilt angle to correct for coma aberration caused by the tilt angle whereas spherical aberration can be corrected by other one or more of the other methods described herein…”, such that it is mechanical driver.
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 § 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.

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 Nagura’s laser system with a spatial light modulator, as taught by Ghauri, in order to provide the capability of a more uniform irradiance distribution of beam cross-section (refer to abstract cited: “…an optical amplifier coupled to the spatial modulator to receive the laser beam output from the spatial light modulator and generate an amplified laser beam containing the same optical pattern as generated by the spatial light modulator, the amplified laser beam from the optical amplifier having a substantially uniform amplification across the cross-section of the beam, the amplified beam maintaining the substantially uniform irradiance distribution over its beam cross-section …”).
Claims 14-15 and 17-18 are rejected under 35 U.S.C. 103 as obvious over Nagura (US2007/0104045A1 previously cited) herein set forth as Nagura, in view of Togashi (US2001/0046195A1 previously cited) herein set forth as Togashi, further in view of Sato et al (US7248543B2 newly cited) herein set forth as Sato, and further in view of Barron et al (US2006/0196858A1 previously cited) herein set forth as Barron.
Regarding claim 14, the modification of Nagura, Togashi and Sato discloses substantially all features set forth in claim 1, Nagura does not specifically disclose wherein the laser light source is configured to provide pulsed laser light having a pulse length of less than 10 picoseconds.
In the field of marking and scanning, Barron discloses wherein the laser light source is configured to provide pulsed laser light range of fs to ps(refer to Paragraph 0014 cited: “…This regime relies on the use of a tightly focused pulsed laser beam with extremely short pulse duration, i.e., in the range of a few fs (fs: femtosecond, 1 fs=10.sup.-15 s) to about 200 ps (ps: picosecond, 1 ps=10.sup.-12 s).…”).
Barron does not specifically discloses wherein the laser light source is configured to provide pulsed laser light having a pulse length of less than 10 picoseconds.
However, since Barron disclosed value is lie inside/ overlap the range disclosed by the present application, 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 wherein the laser light source is configured to provide pulsed laser light having a pulse length of less than 10 picoseconds, in this case where the claimed ranges “overlap or lie inside ranges disclosed by the prior art” a prima facie case of obviousness exists. Refer In re Wertheim, 541 F.2d 257, 191 USPQ 90 (CCPA 1976); In re Woodruff, 919 F.2d 1575, 16 USPQ2d 1934 (Fed. Cir. 1990), such that it would provide a more efficient laser and consume lesser energy (refer to Paragraph 0014 cited: “…be comparable or a few times higher than the threshold energy required to induce permanent structural changes (damages) in the host transparent material, for the selected laser wavelength and focusing characteristics …”).
Regarding claim 15, the modification of Nagura, Togashi and Sato discloses substantially all features set forth in claim 1, Nagura does not specifically disclose wherein the laser light source is configured to provide pulsed laser light with pulse energies of between 10nJ and 300nJ.
In the field of marking and scanning, Barron discloses wherein the laser light source is configured to provide pulsed laser light with pulse energies of between 20nJ and 90nJ (refer to Paragraph 0017 cited: “…using laser pulses carrying an energy that was varied in the range from about 20 nJ (nanoJoules) to 90 nJ …”).
Barron does not specifically discloses the range of 10nJ and 300nJ.
However, since Barron disclosed value is lie inside/ overlap the range disclosed by the present application, 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 range of 10nJ to 300nJ, in this case where the claimed ranges “overlap or lie inside ranges disclosed by the prior art” a prima facie case of obviousness exists. Refer In re Wertheim, 541 F.2d 257, 191 USPQ 90 (CCPA 1976); In re Woodruff, 919 F.2d 1575, 16 USPQ2d 1934 (Fed. Cir. 1990), such that it would provide a more efficient laser and consume lesser energy (refer to Paragraph 0014 cited: “…be comparable or a few times higher than the threshold energy required to induce permanent structural changes (damages) in the host transparent material, for the selected laser wavelength and focusing characteristics …”).
Regarding claim 17 and 18, the modification of Nagura, Togashi and Sato discloses substantially all features set forth in claim 1, Nagura does not specifically disclose such sample is diamond or gemstone.
In the field of marking and scanning, Barron discloses that the sample can be gemstone and diamond (refer to abstract cited: “…A method and an apparatus for laser marking indicia in the volume of gemstones such as diamonds …”).
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 Nagura’s laser system’s sample to be gemstone and diamond, as taught by Barron, such that it would increase the marketability of Okamoto’s laser system, such that would increase in value, utilities and demand of the laser system, and provide different option of marking.
Claim 16 is rejected under 35 U.S.C. 103 as obvious over Nagura (US2007/0104045A1 previously cited) herein set forth as Nagura, in view of Togashi (US2001/0046195A1 newly cited) herein set forth as Togashi, further in view of Sato et al (US7248543B2 newly cited) herein set forth as Sato, and further in view of Sakamoto et al (US8187689B2 previously cited) herein set forth as Sakamoto.
Regarding claim 16, the modification of Nagura, Togashi and Sato discloses substantially all features set forth in claim 1, Nagura, Togashi or Sato does not specifically disclose wherein the one or more optical elements are configured to focus the laser light within the sample with an optical numerical aperture of at least 0.8, 1, or 1.2.
In the field of marking and scanning, Sakamoto discloses wherein the one or more optical elements are configured to focus the laser light within the sample with an optical numerical aperture is 0.85 (refer to Col 10 line 63-64 cited: “…Numerical aperture N.A.=0.85, laser wavelength .lamda.=405 nm, recording linear velocity=4.9 m/s, mark write pulse=30 ns…”).
Sakamoto does not specifically discloses numerical aperture of at least 0.8, 1, or 1.2.
However, since Sakamoto disclosed value is lie inside the range disclosed by the present application, 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 a numerical aperture is 0.85, in this case where the claimed ranges “overlap or lie inside ranges disclosed by the prior art” a prima facie case of obviousness exists. Refer In re Wertheim, 541 F.2d 257, 191 USPQ 90 (CCPA 1976); In re Woodruff, 919 F.2d 1575, 16 USPQ2d 1934 (Fed. Cir. 1990), such that it would complete the marking in a short time (refer to Col 1 line 16-17 cited: “…a large number of replica substrates may be manufactured in a short time at low cost…”).
