Response to Arguments
Claim Rejections – 35 U.S.C. §§ 102-103
I. With respect to the rejection of Claim(s) 1-5 and 10-13 – or as stated below - is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by US 2010/0316556 to Wei, et al., the Remarks traverse on the amendment narrowing Claim 1 and Claim 10 to recite the pressure drop, as claimed. (Remarks of 6/5/2026 at 8). The amendment is persuasive insofar as the prior art rejections are concerned. The rejection is WITHDRAWN.
II. With respect to the rejection of Claim(s) 8-9 under 35 U.S.C. 103 as being unpatentable over US 2010/0316556 to Wei, et al., the rejection is WITHDRAWN in view of the discussion above.
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.
I. Claims 1-13 – or as stated below – is/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.
MPEP 2173.05(b) II states:
II. REFERENCE TO AN OBJECT THAT IS VARIABLE MAY RENDER A CLAIM INDEFINITE
A claim may be rendered indefinite when a limitation of the claim is defined by reference to an object and the relationship between the limitation and the object is not sufficiently defined. That is, where the elements of a claim have two or more plausible constructions such that the examiner cannot readily ascertain positional relationship of the elements, the claim may be rendered indefinite. See, e.g., Ex parte Miyazaki, 89 USPQ2d 1207 (Bd. Pat. App. & Inter. 2008) (precedential) and Ex parte Brummer, 12 USPQ2d 1653 (Bd. Pat. App. & Inter. 1989). In Miyazaki, the Board held that claims to a large printer were not sufficiently definite because:
The language of claim 1 attempts to claim the height of the paper feeding unit in relation to a user of a specific height who is performing operations on the printer.... Claim 1 fails to specify, however, a positional relationship of the user and the printer to each other.
Miyazaki, 89 USPQ2d at 1212. In Brummer, the Board held that a limitation in a claim to a bicycle that recited "said front and rear wheels so spaced as to give a wheelbase that is between 58 percent and 75 percent of the height of the rider that the bicycle was designed for" was indefinite because the relationship of parts was not based on any known standard for sizing a bicycle to a rider, but on a rider of unspecified build. Brummer, 12 USPQ2d at 1655.
On the other hand, a claim limitation specifying that a certain part of a pediatric wheelchair be "so dimensioned as to be insertable through the space between the doorframe of an automobile and one of the seats" was held to be definite. Orthokinetics, Inc. v. Safety Travel Chairs, Inc., 806 F.2d 1565, 1 USPQ2d 1081 (Fed. Cir. 1986). The court stated that the phrase "so dimensioned" is as accurate as the subject matter permits, noting that the patent law does not require that all possible lengths corresponding to the spaces in hundreds of different automobiles be listed in the patent, let alone that they be listed in the claims.
Here, Claim 1 and Claim 10 refer to “the substrate layer formed at the lower portion of the growth furnace.” The substrate “layer” is formed of particles (S. 4: [0081]) introduced through a hopper. (S. 9: [0184] – “a component that introduces the substrates into the system through the hopper 251, to the formation furnace 202a”). See generally (S. 12: [0234] et seq.) (discussing continuous production). In batch operations, the substrates are apparently added manually, at the discretion of the user. (S. 12: [0217]-[0219]). As understood, in either case (continuous or batch), this amount of substrate is an object that is variable; something controlled by the user via a valve on the bottom of a hopper, or manually added to a batch reactor. The variable thickness of the layer of substrates in turn would give rise to different (i.e. variable) pressure drops. Thus, the comparison between “the total area of the gas injection ports…” language is indefinite, as it is in reference to something that is variable.
Dependent claims not specifically addressed import the issues of the claims from which they depend.
Conclusion
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).
A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
