Office Action

§102 §103 §112
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 . Continued Examination Under 37 CFR 1.114 A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 4 February 2026 has been entered. Election/Restrictions Applicant’s election without traverse of Species A, claims 1-8 in the reply filed on 3 July 2025 was previously acknowledged. Claims 9-14 are withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to a nonelected invention, there being no allowable generic or linking claim. Claims 15-17 are added. 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: shared remote plasma unit wherein no specific structure for performing the function was located in the specification. 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 the first paragraph of 35 U.S.C. 112(a): (a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention. The following is a quotation of the first paragraph of pre-AIA 35 U.S.C. 112: The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention. As discussed above, “shared remote plasma unit” invokes interpretation under U.S.C. 112(f). However, no reference thereof in the disclosure details a specific structure to perform the claimed function attributed thereto. Without any disclosure of any structure, materials, or acts for performing the functions or any link of structure to the functions, one cannot conclude that the inventor was in possession of the claimed invention. Therefore, claims 1-8 are rejected under 35 U.S.C. 112(a) or pre-AIA 35 U.S.C. 112, first paragraph. In order to expedite examination, any feature capable of performing the claimed function has been interpreted as readable thereon. Any claim not mentioned specifically is rejected based on its dependency. 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. Claim 1 limitation “shared remote plasma unit” invokes 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. However, the written description fails to disclose the corresponding structure, material, or acts for performing the entire claimed function and to clearly link the structure, material, or acts to the function. Therefore, claims 1-8 are indefinite and are rejected under 35 U.S.C. 112(b) or pre-AIA 35 U.S.C. 112, second paragraph. See above for claim interpretation. Any claim not mentioned specifically is rejected based on its dependency. Applicant may: (a) Amend the claim so that the claim limitation will no longer be interpreted as a limitation under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph; (b) Amend the written description of the specification such that it expressly recites what structure, material, or acts perform the entire claimed function, without introducing any new matter (35 U.S.C. 132(a)); or (c) Amend the written description of the specification such that it clearly links the structure, material, or acts disclosed therein to the function recited in the claim, without introducing any new matter (35 U.S.C. 132(a)). If applicant is of the opinion that the written description of the specification already implicitly or inherently discloses the corresponding structure, material, or acts and clearly links them to the function so that one of ordinary skill in the art would recognize what structure, material, or acts perform the claimed function, applicant should clarify the record by either: (a) Amending the written description of the specification such that it expressly recites the corresponding structure, material, or acts for performing the claimed function and clearly links or associates the structure, material, or acts to the claimed function, without introducing any new matter (35 U.S.C. 132(a)); or (b) Stating on the record what the corresponding structure, material, or acts, which are implicitly or inherently set forth in the written description of the specification, perform the claimed function. For more information, see 37 CFR 1.75(d) and MPEP §§ 608.01(o) and 2181. 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. Claim(s) 1-6 and 17 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by U.S. Patent Pub. No. 2010/00012273 to Sankarakrishnan et al. Regarding claim 1: Sankarakrishnan et al. disclose a substrate processing apparatus, comprising: a plurality of reaction chambers (Fig. 2, 202x2); a shared remote plasma unit (262) configured to (i.e. capable of) receiving a cleaning gas (see, e.g., paras. 37 and 47); a plurality of first cleaning gas lines (e.g., 292 and 296) configured to fluidly couple the shared remote plasma unit to the reaction chambers, wherein each of the first cleaning gas lines is provided with a respective valve (e.g. 300; also see e.g., para. 35) and is connected to a sidewall (212) of each reaction chamber of the plurality of reaction chambers. Paragraph 35 of Sankarakrishnan et al. states: “It is also contemplated that each region 202 may have gas delivery thereto controlled by a separate dedicated valve 300 so that the flow of cleaning gas may be delivered selectively and independently to each region 202, including delivering cleaning gas to one of the regions 202 and not the other.” Note: each region 202 corresponds to individual ones of the plurality of reaction chambers. With respect to claim 2, which is drawn to the identity of a gas used in the apparatus during an intended use thereof, it is noted that the courts have ruled expressions relating the apparatus to contents thereof during an intended operation are of no significance in determining patentability of the apparatus claim. Ex parte Thibault, 164 USPQ 666, 667 (Bd. App. 1969). Nevertheless, it is also noted that Sankarakrishnan et al. teaches that at least one of the claimed gases may be used for processing (see, e.g., para. 44). With respect to claim 3, Sankarakrishnan et al. further disclose the apparatus comprising a susceptor (230) positioned within each reaction chamber of the plurality of reaction chambers, each susceptor constructed and arranged to support a substrate. With respect to claims 4-5, Sankarakrishnan et al. further disclose the apparatus comprising a shower plate (274 and 276) constructed and arranged to face each of the susceptors, wherein each shower plate is provided with plurality of holes (280 and 284) capable of supplying the cleaning gas. With respect to claim 6, Sankarakrishnan et al. further disclose the apparatus comprising a plurality of second cleaning lines/process gas line (each 290 and each 260) each of which is disposed between the shared remote plasma unit and a respective shower plate, including the shower plate. With respect to claim 17, which is drawn to intended use of the claimed apparatus of which Sankarakrishnan et al. is capable, it is noted that the courts have ruled a claim containing a “recitation with respect to the manner in which a claimed apparatus is intended to be employed does not differentiate the claimed apparatus from a prior art apparatus” if the prior art apparatus teaches all the structural limitations of the claim. Ex parte Masham, 2 USPQ2d 1647 (Bd. Pat. App. & Inter. 1987). 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. This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention. Claim(s) 7-8 and 15-16 is/are rejected under 35 U.S.C. 103 as being unpatentable over Sankarakrishnan et al. as applied to claims 1-6 and 17 above and as further set forth below. With respect to claim 7, Sankarakrishnan et al. disclose the substrate processing apparatus substantially as claimed and as described above. However, Sankarakrishnan et al. fails to each of the second cleaning lines/process gas lines is provided with a respective gate valve to supply a process gas to the reaction chamber through the respective shower plate. Nevertheless, as described above, elsewhere in Sankarakrishnan et al. it is disclosed that using individual, separate, dedicated valves for providing a gas from a shared source to two separate processing regions/structures via separate gas lines allows for a gas to be delivered selectively and independently to the separate processing regions/structures, including delivering a gas to one region/structure and not the other (see, e.g., para. 35). Thus, it would have been obvious to one of ordinary skill in the art before Applicant’s invention was effectively filed to have provided in Sankarakrishnan et al. each of the second cleaning lines/process gas lines with individual, separate, dedicated gate valves in order to allow for a process gas to be delivered selectively and independently to the separate processing regions, including delivering the process gas to one region and not the other as taught elsewhere in Sankarakrishnan et al. With respect to claims 8 and 16, which are drawn to intended uses of the claimed apparatus of which modified Sankarakrishnan et al. is capable, it is noted that the courts have ruled a claim containing a “recitation with respect to the manner in which a claimed apparatus is intended to be employed does not differentiate the claimed apparatus from a prior art apparatus” if the prior art apparatus teaches all the structural limitations of the claim. Ex parte Masham, 2 USPQ2d 1647 (Bd. Pat. App. & Inter. 1987). With respect to claim 15, modified Sankarakrishnan et al. fails to disclose each process gas line is below the respective gate valve. However, the courts have ruled the mere rearrangement of parts which does not modify the operation of a device is prima facie obvious. In re Japikse, 181 F.2d 1019, 86 USPQ 70 (CCPA 1950). In re Kuhle, 526 F.2d 553, 188 USPQ 7 (CCPA 1975). In the instant case there is no evidence that the exact position of the respective gate valves provided as described above would affect the function as claimed. Response to Arguments Applicant’s arguments with respect to claim(s) 1-8 and 15-17 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. Conclusion The prior art made of record previously and not relied upon is considered pertinent to applicant's disclosure. US Patent Pubs. 2006/0266288; 2014/0374024; and 2017/0294292 disclose apparatus wherein a remote plasma unit is shared by a plurality of reaction chambers.
