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.
Claim 10 is rejected under 35 U.S.C. 112(b) as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor regards as the invention. Claim “using” a reactor apparatus but, since the claim does not set forth any steps involved in the method/process, it is unclear what method/process applicant is intending to encompass. A claim is indefinite where it merely recites a use without any active, positive steps delimiting how this use is actually practiced. Replacing “by using” in line 2 with “in” is suggested.
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)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention.
Claims 1-10 are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Ida et al. (WO 2022/265056).
Ida et al. discloses claimed reactor apparatus comprising a plurality of first cooling pipes each having a serpentine portion that extends linearly or while curving and at least two of the plurality of first cooling pipes have different distances from an inner wall surface of a reactor. The reactor apparatus also contains a plurality of baffles and one part of a plurality of first cooling pipes is arranged at a position that is between two baffles and spaced apart from the inner wall surface of the reactor. The baffles include a second cooling pipe. The reactor apparatus is also equipped with a reflux condenser and jacket. See Figure 1, Figure 2, Figure 4, and Figure 6. The reactor has an internal capacity of 40 to 300 m3 (paragraph [0038]). The ratio if surface area of the serpentine portion in relation to internal capacity of the reactor is 0.1 to 0.9 m2/m3 (paragraph [0097]). The reactor apparatus is designed for carrying out suspension polymerization of vinyl chloride.
Applicant cannot rely upon the certified copy of the foreign priority application to overcome this rejection because a translation of said application has not been made of record in accordance with 37 CFR 1.55. When an English language translation of a non-English language foreign application is required, the translation must be that of the certified copy (of the foreign application as filed) submitted together with a statement that the translation of the certified copy is accurate. See MPEP §§ 215 and 216.
Claims 1-10 are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Saito et al. (WO 2022/265057).
Saito et al. discloses claimed reactor apparatus comprising a plurality of first cooling pipes each having a serpentine portion that extends linearly or while curving and at least two of the plurality of first cooling pipes have different distances from an inner wall surface of a reactor. The reactor apparatus also contains a plurality of baffles and one part of a plurality of first cooling pipes is arranged at a position that is between two baffles and spaced apart from the inner wall surface of the reactor. The baffles include a second cooling pipe. The reactor apparatus is also equipped with a reflux condenser and jacket. See Figure 1, Figure 2, Figure 4, and Figure 6. The reactor has an internal capacity of 40 to 300 m3 (paragraph [0044]). The ratio if surface area of the serpentine portion in relation to internal capacity of the reactor is 0.1 to 0.9 m2/m3 (paragraph [0105]). The reactor apparatus is designed for carrying out suspension polymerization of vinyl chloride.

See MPEP §§ 215 and 216.
Double Patenting
Claims 1-10 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-14 of copending Application No. 18/518,617. Although the claims at issue are not identical, they are not patentably distinct from each other. Copending claims are drawn to a reactor apparatus having a reactor having a straight body having a tubular shape, a plurality of cooling pipes arranged inside the straight body for circulating a coolant, at least two of the plurality of cooling pipes have different distances from an inner wall surface of the straight body, each of the plurality of cooling pipes has a serpentine portion that extends while repeatedly bending, the serpentine portion includes a plurality of extending portions that extend linearly or extend while curving and a plurality of bending portions that couple ends of two adjacent extending portions, and the internal volume of the reactor is 40 to 300 m3. Copending claims are also drawn to a vinyl-based manufacturing method using the reactor apparatus.
While copending claims do not describe all features recited in instant claims, one of ordinary skill in the art gleans from the disclosure that the reactor apparatus of copending claims is substantially the same as, and therefore not patentably distinct from, the reactor apparatus of instant claims. Applicant’s attention is drawn to MPEP § 804 where it is disclosed that “the specification can always be used as a dictionary to learn the meaning of a term in a patent claim.” In re Boylan, 392 F. 2d 1017, 157 USPQ 370 (CCPA 1986). Further, those portions of the specification which provide support for the patent claims may also be examined and considered when addressing the issue of whether a claim in an application defines an obvious variation of an invention claimed in the patent. In re Vogel, 422 F.2d 438, 164 USPQ 619,622 (CCPA 1970).
This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented.

Copending claims are drawn to a reactor apparatus having a reactor having a straight body having a tubular shape, a plurality of first cooling pipes arranged inside the reactor for circulating a coolant, each of the plurality of cooling pipes has a serpentine portion that extends while repeatedly bending, the serpentine portion includes a plurality of extending portions that extend linearly or extend while curving and a plurality of bending portions that couple ends of two adjacent extending portions, a plurality of baffles which extend substantially parallel to the extending direction of the straight body, and a second cooling pipe which is arranged inside at least one of the plurality of baffles. Copending claims are also drawn to a vinyl-based manufacturing method using the reactor apparatus.

Conclusion
The present invention is drawn to a reactor apparatus comprising a reactor having a tubular shape and a plurality of first cooling pipes arranged inside the reactor for circulating a coolant, wherein each of the plurality of first cooling pipes has a serpentine portion that extends while repeatedly bending, the serpentine portion includes a plurality of extending portions that extend linearly or extend while curving, and a plurality of bending portions that couple ends of two adjacent extending portions, among the plurality of extending portions, at least two of the plurality of first cooling pipes have different distances from an inner wall surface of the reactor, and among the at least two of plurality of first cooling pipes, a length of at least one part of the plurality of extending portions included in a first cooling pipe having a smallest distance from the inner wall surface of the reactor is less than two-thirds of a length of a circumference of the inner wall surface.
Subject of claims is patentably distinct over prior art listed in Applicant’s PTO-1449 and over prior art cited in the accompanying PTO-892.
The closest reference is Ueda et al. (JP 7-233202; US 5,612,437). Prior art teaches a polymerization apparatus comprising a reactor having a tubular shape, serpentine cooling pipes arranged inside the reactor for circulating a coolant, wherein the cooling pipes are arranged between two baffles. The reactor apparatus is also equipped with a reflux condenser. Prior art does not teach a reactor wherein at least two of a plurality of cooling pipes have different distances from an inner wall surface of the reactor.
