Response to Amendment
Election/Restrictions
Claims 43, 46, 48-49, 58, 60-67 are allowable. The restriction requirement between inventions and species, as set forth in the Office action mailed on January 17, 2025, has been reconsidered in view of the allowability of claims to the elected invention pursuant to MPEP § 821.04(a). The restriction requirement is hereby withdrawn as to any claim that requires all the limitations of an allowable claim. Specifically, the restriction requirement of January 17, 2025 is partially withdrawn. Claims 44 and 50, directed to the electrode surface species and the cleaning species, respectively, are no longer withdrawn from consideration because the claim(s) requires all the limitations of an allowable claim. However, claims 10 and 22-23, directed to solid support systems remain withdrawn from consideration because the patentability of a product does not depend on its method of production. See MPEP § 2113.
In view of the above noted withdrawal of the restriction requirement, applicant is advised that if any claim presented in a divisional application is anticipated by, or includes all the limitations of, a claim that is allowable in the present application, such claim may be subject to provisional statutory and/or nonstatutory double patenting rejections over the claims of the instant application.
Once a restriction requirement is withdrawn, the provisions of 35 U.S.C. 121 are no
longer applicable. See In re Ziegler, 443 F.2d 1211, 1215, 170 USPQ 129, 131-32 (CCPA 1971). See also MPEP § 804.01.
Claim Rejections - 35 USC § 112
Claims 44 and 50 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 44
lines 1-2, recite “wherein the electrode surface comprises platinum, titanium, or a combination thereof”.
Claim 43, line 4, recite “wherein the electrode surface comprises a surface of a semiconductor chip”.
It is unclear from the claim language what the relationship is between the surface of a semiconductor chip and the platinum, titanium, or a combination thereof.
Claim 50
line 1, is dependent upon cancelled claim 47.
line 1, “the compound” lacks antecedent basis.
Antecedent basis must be laid for each recited element in a claim, typically, by
introducing each element with the indefinite article (“a” or “an”). See Slimfold Mfg. Co. v. Kincaid Properties, Inc., 626 F. Supp 493, 495 (N.D. Ga. 1985), aff'd, 810 F.2d 1113 (Fed. Cir. 1987) (citing P. Rosenberg, 2 Patent Law Fundamentals § 14.06 (2d. Ed. 1984)). Subsequent mention of an element is to be modified by the definite article “the”, “said” or “the said,” thereby making the latter mention(s) of the element unequivocally referable to its earlier recitation.
Allowable Subject Matter
The following is a statement of reasons for the indication of allowable subject matter:
Claims 43-44, 46, 48-50, 58 and 60-67 define over the prior art of record because the prior art does not contain any language that teaches or suggests a method of preparing an electrode surface for oligonucleotide synthesis, comprising the steps of: (a) cleaning, (a-1) electrochemically cleaning, (b) introducing, (c) electrografting, (d) stripping and (e) performing as presently claimed, esp., wherein the electrode surface comprises a surface of a semiconductor chip, wherein the cleaning in (a) is performed by using a plasma, (a-1) electrochemically cleaning the plasma-cleaned electrode surface prior to step (b), and wherein the electrochemically cleaning is performed in the presence of p-toluenesulfonic acid. Therefore, a person skilled in the art would not have been motivated to adopt the above conditions, and a prima facie case of obviousness cannot be established.
Maurer et al. and CN 108774588 do not teach (a-1) electrochemically cleaning the plasma-cleaned electrode surface prior to step (b), wherein the electrochemically cleaning is
performed in the presence of p-toluenesulfonic acid.
Claims 44 and 50 would be allowable if rewritten or amended to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action.
