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.
Claims 7, 17 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.
Claim 7 “wherein the downstream annular row comprises a first angular series of blades centered on the angular position at 3 o'clock or on the angular position at 9 o'clock and a second angular series of blades centered on the angular position at 12 o'clock or on the angular position at 6 o'clock, the average radial dimension of the blades of the first angular series being less than the average radial dimension of the blades of the second angular series” is unclear what the relationship of the italicized text and the “two blades with a minimal radial dimension which are respectively angularly positioned at the angular position at 3 o'clock and at the angular position at 9 o'clock”, “the first blade” and “the second blade” of claim 1. Applicant appears to be claiming the at least some of the same elements as in claim 1 but without specifying the relationship between the two claims. Claim 17 has analogous issues but with respect to the relationship of the italicized text and first groups of blades, second group of blades and third group of blades of claim 12.
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.
Claim 16 is rejected under 35 U.S.C. 112(d) or pre-AIA 35 U.S.C. 112, 4th paragraph, 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 16 requires “wherein the blades of the at least one group of blades are arranged circumferentially contiguously in an angular sector around the longitudinal axis”. However, claim 12 already requires “the blades of each group of blades are arranged circumferentially so they are contiguous within an angular sector around the longitudinal axis” 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.
Allowable Subject Matter
Claims 1, 3-6, 8-9, 11-15 and 18-20 are allowed.
