DETAILED ACTION
Notice of Pre-AIA or AIA Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Claim Interpretation
The following is a quotation of 35 U.S.C. 112(f):
(f) Element in Claim for a Combination. – An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof.
The following is a quotation of pre-AIA 35 U.S.C. 112, sixth paragraph:
An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof.
The claims in this application are given their broadest reasonable interpretation using the plain meaning of the claim language in light of the specification as it would be understood by one of ordinary skill in the art. The broadest reasonable interpretation of a claim element (also commonly referred to as a claim limitation) is limited by the description in the specification when 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is invoked.
As explained in MPEP § 2181, subsection I, claim limitations that meet the following three-prong test will be interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph:
(A) the claim limitation uses the term “means” or “step” or a term used as a substitute for “means” that is a generic placeholder (also called a nonce term or a non-structural term having no specific structural meaning) for performing the claimed function;
(B) the term “means” or “step” or the generic placeholder is modified by functional language, typically, but not always linked by the transition word “for” (e.g., “means for”) or another linking word or phrase, such as “configured to” or “so that”; and
(C) the term “means” or “step” or the generic placeholder is not modified by sufficient structure, material, or acts for performing the claimed function.
Use of the word “means” (or “step”) in a claim with functional language creates a rebuttable presumption that the claim limitation is to be treated in accordance with 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. The presumption that the claim limitation is interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is rebutted when the claim limitation recites sufficient structure, material, or acts to entirely perform the recited function.
Absence of the word “means” (or “step”) in a claim creates a rebuttable presumption that the claim limitation is not to be treated in accordance with 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. The presumption that the claim limitation is not interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is rebutted when the claim limitation recites function without reciting sufficient structure, material or acts to entirely perform the recited function.
Claim limitations in this application that use the word “means” (or “step”) are being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, except as otherwise indicated in an Office action. Conversely, claim limitations in this application that do not use the word “means” (or “step”) are not being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, except as otherwise indicated in an Office action.
This application includes one or more claim limitations that do not use the word “means,” but are nonetheless being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, because the claim limitation(s) uses a generic placeholder that is coupled with functional language without reciting sufficient structure to perform the recited function and the generic placeholder is not preceded by a structural modifier. Such claim limitation(s) is/are: “flow conditioning elements…configured to cause recombination of the fluid flow, split and modulated by the splitter element, into a pulsatile jet of fluid projecting from the nozzle outlet along the main direction that coincides with the rotation axis of the rotor element” in claims 20, 38, and 41.
Because this/these claim limitation(s) is/are being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, it/they is/are being interpreted to cover the corresponding structure described in the specification as performing the claimed function, and equivalents thereof. Such corresponding structure(s) is are: a first embodiment of the flow conditioning elements is “a plurality of outlet conduits”, as described in paragraph 63 of the Specification, and a second embodiment of the flow conditioning elements is “a plurality of turning vanes”, as described in paragraph 70 of the Specification.
If applicant does not intend to have this/these limitation(s) interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, applicant may: (1) amend the claim limitation(s) to avoid it/them being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph (e.g., by reciting sufficient structure to perform the claimed function); or (2) present a sufficient showing that the claim limitation(s) recite(s) sufficient structure to perform the claimed function so as to avoid it/them being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph.
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.
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 20-42 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.
Claims 20, 38, and 41 all recite the limitation "the passage" in line 7. There is insufficient antecedent basis for this limitation in these claims.
Claims 21-37, 39-40, and 42 are rejected as being indefinite for depending from indefinite claims 20, 38, and 41, respectively.
Claim Rejections - 35 USC § 102
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
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:

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.
Claims 29-31 are rejected under 35 U.S.C. 103 as being unpatentable over Pouppirt in view of Walker (US 2004/0195360).
Regarding claim 29, Pouppirt discloses the nozzle described regarding claim 20, but not further wherein the flow conditioning elements include a plurality of turning vanes, and wherein a corresponding one of the turning vanes is provided downstream of each splitter opening.
Walker teaches a nozzle (10) with a nozzle inlet (at 44) and a nozzle outlet (at 12), comprising:
a shell (12/20/40/50);
a rotor element (16) located inside the shell (fig. 3) and configured to be driven into rotation about a rotation axis upon being subjected to the action of a fluid flow entering the nozzle inlet and circulating through the nozzle towards the nozzle outlet (par. 25);
a stationary splitter element (38) located inside the shell (fig. 3), downstream of the rotor element (fig. 3), along the passage of the fluid flow (fig. 3), wherein the splitter element comprises a plurality of splitter openings (42, see fig. 8) communicating with a downstream end of the rotor element (fig. 3) to cause splitting and modulation of the fluid flow as a function of rotation of the rotor element with respect to the stationary splitter element (par. 26, fig. 8), and
flow conditioning elements (24, which are turning vanes) located inside the shell (fig. 3), downstream of the splitter openings (fig. 3), the flow conditioning elements comprising a plurality of turning vanes (par. 24), wherein a corresponding one of the turning vanes is provided downstream of each splitter opening (fig, 3).
It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to have modified the flow conditioning elements of the nozzle of Pouppirt to further comprising a plurality of turning vanes, wherein a corresponding one of the turning vanes is provided downstream of each splitter opening, as taught by Walker, since this was known to impart a further rotational drive torque to the nozzle (Walker, par. 30, 35).
Regarding claim 30, Pouppirt in view of Walker discloses the nozzle described regarding claim 29, and further wherein the turning vanes are arranged to cause recombination of the fluid flow, split and modulated by the splitter element, upstream of the nozzle outlet (Pouppirt discloses flow conditioning elements that begin to converge upstream of the nozzle outlet, see fig. 3).
Regarding claim 31, Pouppirt in view of Walker discloses the nozzle described regarding claim 29, and further wherein the turning vanes form an integral part of the splitter element (fig. 3).
Claims 36 and 41-42 are rejected under 35 U.S.C. 103 as being unpatentable over Pouppirt in view of Spinnett (US 4,508,665).
Regarding claim 36, Pouppirt discloses the nozzle described regarding claim 20, but not further wherein an outer peripheral surface of the rotor element is delineated by a generally conical or ogival surface of revolution.
Spinnett teaches a nozzle (50) comprising a rotor element (52), wherein an outer peripheral surface (55) of the rotor element is delineated by a generally conical or ogival surface of revolution (figs. 2, 4).
It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to have modified the rotor element of the nozzle of Pouppirt to include an outer peripheral surface delineated by a generally conical or ogival surface of revolution, as taught by Spinnett, since this was known to preclude interference between the rotor element and other elements of the nozzle (col. 6, ln. 39-40).
Regarding claim 41, Pouppirt discloses a nozzle (figs. 3, 4) with a nozzle inlet (fig. 3 – at right end) and a nozzle outlet (fig. 3 – at left end), comprising:
a shell (10/12);
a rotor element (28) located inside the shell (fig. 3) and configured to be driven into rotation about a rotation axis upon being subjected to the action of a fluid flow entering the nozzle inlet and circulating through the nozzle towards the nozzle outlet (col. 3, ln. 39-40); and
a stationary splitter element (11) located inside the shell (fig. 3), downstream of the rotor element (fig. 3), along the passage of the fluid flow (fig. 3), wherein the rotation axis of the rotor element coincides with a main direction along which the fluid flow projects from the nozzle outlet (fig. 3),
wherein the rotor element comprises a plurality of peripheral helical grooves (fig. 4 – interpreted to be the grooves formed in element 28, which have a spiral, or helical, shape) configured to permit passage of the fluid flow and cause rotation of the rotor element about the rotation axis (col. 3, ln. 39-40; figs. 3, 4),
wherein the splitter element comprises a plurality of splitter openings (fig. 3 – interpreted to be the openings of 24 at the right end) communicating with a downstream end of the plurality of peripheral helical grooves of the rotor element (fig. 3, 4) to cause splitting and modulation of the fluid flow as a function of rotation of the rotor element with respect to the stationary splitter element (col. 3, ln. 39-42),
wherein the nozzle further comprises flow conditioning elements (24, which are outlet conduits) located inside the shell (fig. 3), downstream of the splitter openings, and configured to cause recombination of the fluid flow, split and modulated by the splitter element, into a pulsatile jet of fluid projecting from the nozzle outlet along the main direction that coincides with the rotation axis of the rotor element (fig. 3 – the flow conditioning elements are all directed toward the axis of the nozzle; col. 3, ln. 40-42 – the finger will open and close the openings and result in a pulsatile jet).
Pouppirt does not disclose wherein an outer peripheral surface of the rotor element is delineated by a generally conical or ogival surface of revolution.
Spinnett teaches a nozzle (50) comprising a rotor element (52), wherein an outer peripheral surface (55) of the rotor element is delineated by a generally conical or ogival surface of revolution (figs. 2, 4).
It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to have modified the rotor element of the nozzle of Pouppirt to include an outer peripheral surface delineated by a generally conical or ogival surface of revolution, as taught by Spinnett, since this was known to preclude interference between the rotor element and other elements of the nozzle (col. 6, ln. 39-40).
Regarding claim 42, Pouppirt in view of Spinnett discloses a device designed to produce a pulsatile jet of fluid (col. 1, ln. 39-40 – “a rotational flutter”), comprising a fluid supply (25) coupled to the nozzle inlet of the nozzle described regarding claim 41 (fig. 3).
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. LaMariana et al. (US 2020/0290062) and Dongo (US 5,920,925) both disclose nozzles having elements of the claimed invention.
