Office Action

§102 §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 . 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. Response to Arguments Applicant’s arguments, see page 5 paragraph 4, filed 03/23/2026, with respect to claims 13-17 have been fully considered and are persuasive. The rejections under 35 U.S.C. §112(b) of 01/05/2026 have been withdrawn. Applicant’s arguments, see page 6 ln 3-7, filed 03/23/2026, with respect to the rejection(s) of claim(s) 13-16 under 35 U.S.C. §102(a)(2) have been fully considered and are persuasive. Therefore, the rejection has been withdrawn. However, upon further consideration, a new ground(s) of rejection is made in view of Bayless (US20210183803A1). Applicant’s arguments, see page 6 lines 11-15, filed 03/23/2026, with respect to the rejection(s) of claim(s) 17 under 35 U.S.C. §103 have been fully considered and are persuasive. Therefore, the rejection has been withdrawn. However, upon further consideration, a new ground(s) of rejection is made in view of Bayless (US20210183803A1). 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 14 and 15 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 applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Claim 14 recites the limitation "the product" in line 2. There is insufficient antecedent basis for this limitation in the claim. For the purposes of examination “the product” is interpreted as -the product substrate-. Claim 15 is rejected as depending from an indefinite claim and failing to claim sufficient additional limitations to overcome the indefiniteness. Claim Rejections - 35 USC § 102 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) 13-17 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Bayless (US20210183803A1). In reference to claim 13: Bayless discloses a substrate system for the production of semiconductor components (abstract, para 0002), comprising: a carrier substrate (“carrier wafer 110”, paras 0025-0028, Fig. 5); a product substrate (“device wafer 424”, paras 0051-0054, Figs. 4-5); and an inorganic separating layer arranged in between the carrier substrate and the product substrate, the product substrate being arranged on the inorganic separating layer (“non-elastic material layer 112”, paras 0028-0029, 0031, Fig. 5), wherein the carrier substrate is separable from the product substrate by irradiation of the inorganic separating layer with a laser unit (para 0033, Fig. 5), and wherein the inorganic separating layer fixes the product substrate on the carrier substrate (Figs. 4-5). In reference to claim 14: In addition to the discussion of claim 13, above, Bayless further discloses wherein at least one further layer is arranged between the inorganic separating layer and the product (paras 0032-0034, Figs. 4-5), wherein the product substrate is fixed to the carrier substrate by the at least one further layer (paras 0032-0034, Figs. 4-5), and wherein the at least one further layer is inorganic (paras 0032-0034, Figs. 4-5). In reference to claim 15: In addition to the discussion of claim 14, above, Bayless further discloses wherein the at least one further layer is a bonding layer (para 0040), and wherein the bonding layer is produced at least from a first oxide layer and a second oxide layer by fusion bonding (para 0040). In reference to claim 16: In addition to the discussion of claim 13, above, Bayless further discloses wherein exclusively inorganic layers are arranged between the carrier substrate and the product substrate (paras 0031-0033, Fig. 5). In reference to claim 17: In addition to the discussion of claim 13, above, Bayless further discloses wherein the inorganic separating layer has a separating layer thickness between 10 nm and 500 nm (para 0030 disclosing 1,000-1,500 angstroms, which is 100-150 nm. See MPEP 2131.03). Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
