Office Action

§102 §103 §112
DETAILED ACTION Representative Figures PNG media_image1.png 1046 677 media_image1.png Greyscale 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 1-5 and 9-15 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, it is unclear what minimal structure is intended by the recitation, “wherein the filtering component is adapted to be assembled against a first identical filtering component so that their facing respective internal faces define a space that is circumferentially compartmented by the contacting respective ribs of said internal face”. Patent claims are required to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor regards as the invention. This language is not seen to comport with this legislative requirement. Moreover, such nebulous and ambiguous language fails to place potential infringers on clear notice as to what constitutes infringement. PNG media_image2.png 600 644 media_image2.png Greyscale Claim 9 makes reference to claim 1 and is therefore, by definition a dependent claim. A dependent claim must further limit a claim from which it depends. Yet, claim 9 recites, “as claimed in claim 1 or a filtering element”. This language means that the subject matter of claim 1 is not necessary, is optional or negated. A dependent claim may not remove or negate limitations from a claim upon which it depends. It is unclear how claim 9 and its dependencies (claims 10-12 and 15) further limit claim 1 from which it depends. For this reason, the scope of claims 9-12 and 15 is incomprehensibly indefinite or ascertainable. Accordingly, art has not been applied against 9-12 and 15. In independent claim 13, it is unclear what is intended by “the passages opening out on compartmented sectors”, or what structure defines the “compartmented sectors”. Claim Rejections - 35 USC § 112(d) The following is a quotation of 35 U.S.C. 112(d): (d) REFERENCE IN DEPENDENT FORMS.—Subject to subsection (e), a claim in dependent form shall contain a reference to a claim previously set forth and then specify a further limitation of the subject matter claimed. A claim in dependent form shall be construed to incorporate by reference all the limitations of the claim to which it refers. Claims 9-12 and 15 are rejected under 35 U.S.C. 112(d), as being of improper dependent form for failing to further limit the subject matter of the claim upon which it depends, or for failing to include all the limitations of the claim upon which it depends. Claim 9 makes reference to claim 1 and is therefore, by definition a dependent claim. A dependent claim must further limit a claim from which it depends. Yet, claim 9 recites, “as claimed in claim 1 or a filtering element”. This language means that the subject matter of claim 1 is not necessary, is optional or negated. A dependent claim may not remove or negate limitations from a claim upon which it depends. It is unclear how claim 9 and its dependencies (claims 10-12 and 15) further limit claim 1 from which it depends. Applicant may cancel the claim(s), amend the claim(s) to place the claim(s) in proper dependent form, rewrite the claim(s) in independent form, or present a sufficient showing that the dependent claim(s) complies with the statutory requirements. Claim Rejections - 35 USC § 102 Claims 1 and 5-8 are rejected under 35 U.S.C. 102(A1/A2) as being anticipated by KR 10-2013-0108334 A (02 OCTOBER 2013) or “Cited Reference 1”. The Office Action of the Korean Patent Office made of record on 22 JANUARY 2026 is adopted as it applies to claims 1 and 5-8 as detailed below.

Patentability shall not be negated by the manner in which the invention was made. Claims 2-3 are rejected under 35 U.S.C. 103 as being unpatentable over KR 10-2013-0108334 A (02 OCTOBER 2013) or “Cited Reference 1”. The Office Action of the Korean Patent Office made of record on 22 JANUARY 2026 is adopted as it applies to claims 2 and 3 as detailed below. PNG media_image7.png 1106 876 media_image7.png Greyscale Claim Rejections - 35 USC § 102 Claims 1 and 6 are rejected under 35 U.S.C. 102(A1/A2) as being anticipated by GRIFFITH (GB 915,341 – 1963). The rationale relating to novelty/anticipation set forth with in the Written Opinion set forth below with respect to claims 1 and 6 is adopted. PNG media_image8.png 740 484 media_image8.png Greyscale PNG media_image9.png 307 635 media_image9.png Greyscale Claim 13 is rejected under 35 U.S.C. 102(A1/A2) as being anticipated by VOCELKA (US 2,631,732 – 1953). The rationale relating to novelty/anticipation set forth in the Written Opinion set forth below with respect to claim 13 is adopted.
