Claim Rejections - 35 USC § 112(b)
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.
Claims 1-10 and 15-22 are 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.

In claim 1 as amended, with respect to, “a core extending between opposing axial ends thereof”, it is unclear to what “thereof” refers. The “opposing axial ends” of the “flush chamber” or the “core”?
The preamble of independent claim 1 specifies a “filter arrangement”. As written the scope of claim 1 and what is intended by this recitation are both unclear. Is the recitation “filter arrangement” intended to define a complete operative apparatus capable of filtering a fluid, or some fraction thereof. In this regard, the transitional phrase “comprising” appears at both line 1 and line 2 of claim 1 making it unclear where the body of the claim begins, thus rendering the scope of the claim unclear and indefinite.
At line 3 of this claim a “flush chamber” is introduced. An individual skilled in the art would understand a “chamber” to be a void, volume, space or cavity. This language is not seen to define structure within the context of the claims. It is unclear what specific structure defines the claimed “flush chamber”. It is unclear what structure defines the boundaries of the “flush chamber”. It is unclear where the “flush chamber” begins or ends.
Allowable Subject Matter
Claims 25-28 are allowed.
The incomprehensibility of claims 1-10 and 15-22 precludes application of prior art.
Response to Arguments
Applicant’s arguments or amendments with respect to those previous rejections no longer appearing above and drawing objections have been effective at removing them.
