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 4-19 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 4 recites the limitation "the zeolite preparation" in line 1. There is insufficient antecedent basis for this limitation in the claim. The claim should be dependent upon claim 3.
Claims 5-9 recite the limitation “the aqueous precursor” in line 2. There is insufficient antecedent basis for this limitation in the claim. All the claims should be dependent upon claim 3 or 4.
Claim 10 recites the limitation “the product of step (b)” in line 2. There is insufficient antecedent basis for this limitation in the claim. The claim should be dependent upon claim 3 or 4.
Claim 11 recites the limitation “the solution of step (b)” in line 2. There is insufficient antecedent basis for this limitation in the claim. The claim should be dependent upon claim 3 or 4.
Claim 15 recites the limitation “the spraydrying” in line 1. There is insufficient antecedent basis for this limitation in the claim. The claim should be dependent upon claim 14.
Claim 18 recites the limitation “the filtered gel” in line 1. There is insufficient antecedent basis for this limitation in the claim. The claim should be dependent upon claim 17.
Claim Rejections - 35 USC § 102
Claims 1-19 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Ravichandran et al. (EP2548644, cited in IDS).
Regarding claim 1, Ravichandran et al. discloses an FCC catalyst additive obtained by spry drying and calcination of a raw material (paragraph 0064). The FCC catalyst additive comprises zeolite 40 to 60 wt%, phosphate 7 to 12 wt%, clay 20 to 40 wt%, and a binder 10 to 40 wt% (paragraph 0064). The binder comprises silica in an amount of 75 to 100 wt% and alumina in an amount of 0 to 25 wt%. The ranges of wt% for alumina are 0 to 10 wt%, and the ranges of wt% for silica are 7.5 to 40 wt%. A summary is shown below.
Minimum silica: 10 wt% binder, 75 wt% silica
Minimum silica = 7.5 wt%
Maximum silica: 40 wt% binder, 100 wt% silica
Maximum silica = 40 wt%
Minimum alumina = 0 wt%
Maximum alumina: 40 wt% binder, 25 wt% alumina
Maximum alumina = 10 wt%
Regarding claim 2, Ravichandran et al. discloses ZSM-5 is used for preparation of the additive (paragraph 0070). ZSM-5 is a pentasil type zeolite. The ZSM-5 zeolite is described as mesoporous (paragraph 0068).
The process limitations in claims 3-19 are noted. However, the disclosed product of Ravichandran et al. and the instantly claimed product appear to be essentially the same, comprised of the same components, and used in the same manner. When the examiner has found a substantially similar product as in the applied prior art, the burden of proof is shifted to applicant to establish that their product is patentably distinct and not the examiner to show the same process of making. In re Brown, 173 USPQ 685 and In re Fessmann, 180 USPQ 324.
