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:
“radiation emitting elements” in claim 15-21 interpreted as pixels, micromirrors [0049-0050] and equivalents thereof.
“radiation transmitting elements” in claim 15-21 interpreted as pixels, micromirrors [0049-0050] and equivalents thereof.
“turning mechanism” in claim 21 interpreted as a robotic arm [0048] and equivalents thereof.
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.
Claim(s) 15-21 is/are rejected under 35 U.S.C. 103 as being unpatentable over Richardson (prev. presented US 2004/0204785) in view of US Patent Application Publication 20200038994 of Demuth et al., hereinafter Demuth and US Patent 5306447 of Marcus et al., hereinafter Marcus.
Regarding claim 15, Richardson teaches an additive chemical vapor deposition CVD manufacturing system (abstract, Fig 2), comprising: a deposition chamber (108 Fig 2) [0080] and deposition surface support (stage 20 Fig 2, [0081]), and an energy source capable (light source 100 Fig 2, [0077]) of generating pulsed light [0081] of at least one specified wavelength [0081] and with at least one specified pulse frequency ([0081], [0103]). Richardson fails to teach at least a first and a second programable radiation modules capable of directing radiation onto a specified deposition surface and initiating chemical vapor deposition at the deposition surface, wherein each programable radiation module comprises individually addressable radiation emitting and/or transmitting elements capable of being activated with the pulsed light from the energy source, and wherein each of the first programmable radiation module and the second programmable radiation module contains a dynamic mask containing one or more of the following: a liquid crystal display (LCD), a digital light processing (DLP) projector and/or digital micromirror device (DMD); and wherein the first programmable radiation module is positioned in a first direction relative to the deposition surface and the second programmable radiation module is positioned in a second direction relative to the deposition surface, thereby the first programmable radiation module and the second radiation module are positioned to irradiate the deposition surface from two different directions, causing a multidirectional crystal growth on the deposition surface. In the same field of endeavor of additive manufacturing using lasers (abstract), Demuth teaches a programmable radiation module (mask 210 Fig 2A) containing a dynamic mask [0056], [0061], [0043] containing a liquid crystal display [0043] to control the irradiation of the substrate with the laser beam as an alternative to scanning with a laser beam because this is more scalable and reduces thermal warpage [0021]. It would have been obvious to a person having ordinary skill in the art before the effective filing date of the claimed invention to modify Richardson to include the programmable radiation module including a dynamic liquid crystal display mask as taught by Demuth because Demuth teaches this is an improvement over single position scanning by a laser (operation of Richardson).
Regarding the inclusion of two programmable radiation modules and the first programmable radiation module is positioned in a first direction relative to the deposition surface and the second programmable radiation module is positioned in a second direction relative to the deposition surface, thereby the first programmable radiation module and the second radiation module are positioned to irradiate the deposition surface from two different directions, causing a multidirectional crystal growth on the deposition surface, in the same field of endeavor of chemical vapor deposition to produce a three dimensional structure (col 1, ln 15-20 and col 2, ln 35-65), Marcus teaches as an alternative to irradiating from one laser source (48 Fig 1), an arrangement in which the structure is built using irradiation from two laser sources that are perpendicular to each other (Fig 4, see 62 and 64). Marcus teaches this enables control of the energy and combination of wavelength to produce the desired material deposition (col 11, ln 64 to col 12, ln 17). It would have been obvious to a person having ordinary skill in the art before the effective filing date of the claimed invention to modify Richardson to include two lasers at different directions relative to the deposition surface because Marcus teaches this a functional alternative that allows for increased control of the irradiation (col 11, ln 64 to col 12, ln 17). Note that in the combination because two laser sources are used, there would be two programmable radiation modules (one for each laser source) and they would follow the beam direction positioning of the laser and therefore be positioned to irradiate the substrate at two different directions. The limitation “causing multidirectional crystal growth on the deposition surface” is directed to the intended use of the apparatus; however Marcus demonstrates this result (see Fig 4).
Regarding claim 16, the combination remains as applied to claim 15 above. Richardson teaches the substrate support is a deposition table (stage 20 Fig 2, [0081]).
Regarding claim 17, the combination remains as applied to claim 15 above. Richardson teaches at least one wall of the deposition chamber comprises one or more radiation transparent windows (107 Fig 2). Further note that Marcus also teaches transparent windows (70, 72 Fig 4) on the chamber walls. Therefore, the position of the transparent window on the chamber wall is an obvious rearrangement of parts assuming arguendo the window of Richardson is not on a chamber wall.
Regarding claim 18, the combination remains as applied to claim 15 above. Richardson teaches the deposition chamber is equipped with at least one gas inlet (23 Fig 2) and at least one gas outlet (line having valve 117, gas scrubber 118, exhaust pump 119, and external port 120 Fig 2 [0082]).
Regarding claim 19, the combination remains as applied to claim 15 above. Demuth as applied in the combination teaches the array of individually addressable radiation-emitting or transmitting elements, is configurable to irradiate individual points of the deposition support surface ([0023]).
Regarding claim 20, the combination remains as applied to claim 15 above. Richardson teaches the energy source is a programmable source of radiation capable of generating impulse light with different frequencies and/or wavelengths ([0081], [0103]).
Regarding claim 21, the combination remains as applied to claim 16 above. Richardson teaches a turning mechanism (21 Fig 2) for relative rotation between the rotatable mandrel or the deposition table and the radiation modules ([0069], note five axis is inclusive of rotation (i.e. rotation around an axis perpendicular to a main surface of the substrate) and that relative rotation is inclusive of tilting of the substrate (i.e. rotation around an axis extending along the bar shown connecting the stage 20 to the turning mechanism 21)).
Claim(s) 16 is/are additionally and/or alternatively rejected under 35 U.S.C. 103 as being unpatentable over Richardson in view of Demuth and Marcus as applied to claim 16 above, and further in view of Brown (prev. presented US 2016/0271870).
Regarding claim 21, the combination remains as applied to claim 16 above. This rejection is provided additionally and/or alternatively in the event applicant can persuasively argue that the five axis movement of Richardson is not inclusive of a relative rotation between the deposition table and the radiation module. In the same field of endeavor of additive manufacturing [0001], Brown teaches a substrate holding table (224 Fig 8, 10) is able to have relative movement between the substrate holding table and the radiation module(s) (160 Fig 8 or 160, 162, 260 Fig 10) including rotation [0103] or translation [0103]. It would have been obvious to a person having ordinary skill in the art at the time the invention was filed to modify the apparatus of Richardson including the movement mechanism (21) to use the movement mechanism of Brown because this represents a simple substitution of one known element for another to achieve predictable results (movement of the substrate to expose different portions to the irradiation).
Response to Arguments
Applicant's arguments filed 01/02/2026, hereinafter reply, have been fully considered but they are not persuasive.
Applicant’s arguments regarding Fang (reply p12-14) is moot in view of the new grounds of rejection including Demuth and Marcus which was necessitated by the claim amendments. Fang is no longer being applied as a reference.
Regarding claim 17 (reply p14-15), Examiner notes that element 107 may be considered on a chamber wall because it is on a wall defining the processing chamber space. It is noted the chamber is not limited to top wall, bottom wall, and side wall(s) only. Additionally, it is noted that newly cited reference Marcus demonstrates windows on the chamber top and side wall as cited above. Therefore the argument is not persuasive.
For these reasons the arguments are not persuasive as to the allowability of the instant claims.
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. US 2015/0234295 teaches a dynamic patterning apparatus (Fig 1).
Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a).
