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 5-6 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.
Regarding claim 5, the term "preferably" renders the claim indefinite because it is unclear whether the limitations following the phrase are part of the claimed invention. See MPEP § 2173.05(d). The same rejection applies to the additional instances of the limitation.
Regarding claim 6, the terms "preferably" and “such as” render the claim indefinite because it is unclear whether the limitations following the phrase are part of the claimed invention. See MPEP § 2173.05(d).

Claim Rejections - 35 USC § 103
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
Claim(s) 21-24 are rejected under 35 U.S.C. 103 as being unpatentable over LaVergne (US 2020/0215372) in view of Achtmann.
Regarding claim 21, LaVergne discloses a firefighting system comprising:
a water supply line (110);
a foaming concentrate dispenser unit (112) connected to the water supply line (Figure 1B); and
a polymer dispenser unit (115) containing a water-soluble polymer (Paragraph 368), said polymer dispenser unit being connected to the water supply line (Figure 1B), but is silent as to whether the polymer is in solid form.
Achtmann discloses a system wherein a water-soluble polymer in a foam composition is in solid form as an alternative to polymer in a liquid form (Column 6, lines 59-63).
It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify LaVergne with the disclosures of Achtmann, providing the polymer in solid form, as the configurations were known alternatives to provide a foam before the effective filing date of the claimed invention, and the modification would have yielded predictable results, including provision of foam for discharge in a fire protection system.
Regarding claim 22, LaVergne in view of Achtmann discloses the firefighting system according to claim 21, wherein the system also comprises two separate supply lines (116, 119) in connection with the water supply line (Figure 1B), wherein the foaming concentrate dispenser unit is connected to one of said two separate supply lines (116) and wherein the polymer dispenser unit is connected to the other (119) of said two separate supply lines (Figure 1B).
Regarding claim 24, LaVergne in view of Achtmann discloses the firefighting system according to any of claim 21, wherein the water supply line (110) is connected to a main water supply line (102) (Figure 1B).
Pertaining to Claims 21 and 23
Regarding claim 21, LaVergne discloses a firefighting system comprising:
a water supply line (206);
a foaming concentrate dispenser unit (212) connected to the water supply line (Figure 2B); and
a polymer dispenser unit (226) containing a water-soluble polymer (Paragraph 368), said polymer dispenser unit being connected to the water supply line (Figure 2B), but is silent as to whether the polymer is in solid form.
Achtmann discloses a system wherein a water-soluble polymer in a foam composition is in solid form as an alternative to polymer in a liquid form (Column 6, lines 59-63).
It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify LaVergne with the disclosures of Achtmann, providing the polymer in solid form, as the configurations were known alternatives to provide a foam before the effective filing date of the claimed invention, and the modification would have yielded predictable results, including provision of foam for discharge in a fire protection system.
Regarding claim 23, LaVergne in view of Achtmann discloses the firefighting system according to claim 21, wherein the foaming concentrate dispenser unit (212) and the polymer dispenser unit (226) are connected to one and the same supply line (210) which in turn is connected to the water supply line (206) (Figure 2B).
