Office Action

§112
DETAILED ACTION The present application is being examined under the pre-AIA first to invent provisions. Continued Examination 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and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114.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 11/24/2025 has been entered. Double Patenting The non-statutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the "right to exclude" granted by a patent and to prevent possible harassment by multiple assignees. See In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); and In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969). A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) may be used to overcome an actual or provisional rejection based on a non-statutory double patenting ground provided the conflicting application or patent is shown to be commonly owned with this application. See 37 CFR 1.130(b). Effective January 1, 1994, a registered attorney or agent of record may sign a terminal disclaimer. A terminal disclaimer signed by the assignee must fully comply with 37 CFR 3.73(b). It is further emphasized that claims 13, 14 and 17 remain rejected under the judicially created doctrine of obviousness-type double patenting s being unpatentable over claims 1-7 of US 11084015. It is maintained that, although the conflicting claims are not identical, they are not patentably distinct from each other because all positively recited features of the instant claims are entirely within the scope of claims 1-7 of US 11084015. The rejection will not be held in abeyance. 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 13-14 and 17-30, as amended, 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 pre-AIA the applicant regards as the invention. In the amended claim 13, it is unclear from the claim language how the ‘polar medium’ recited in line 10 must be inter-related with the ‘polar medium’ recited in the preceding line 6. Similarly, it is unclear how the ‘polar medium’ recited in the paragraph of lines 11—14 must be inter-related with the ‘polar medium’ recited in the preceding lines. The same considerations apply to ‘polar medium’ recited in the second stepof ‘disposing’ and in the step of ‘flowing’, where many recitations in question lack antecedent basis. See also claims 14, 17, 23-24 and 27-28. Note that it is applicants’ responsibility to locate and correct all instances of the raised issues. Response to Arguments All of the Applicant s arguments have been fully considered but they are not persuasive, or moot in view of new grounds of rejection.
