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 .
Information Disclosure Statement
The information disclosure statement (IDS) submitted on 9/11/2025 is in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement is being considered by the examiner.
Double Patenting
The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969).
A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA as explained in MPEP § 2159. See MPEP § 2146 et seq. for applications not subject to examination under the first inventor to file provisions of the AIA . A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b).
The filing of a terminal disclaimer by itself is not a complete reply to a nonstatutory double patenting (NSDP) rejection. A complete reply requires that the terminal disclaimer be accompanied by a reply requesting reconsideration of the prior Office action. Even where the NSDP rejection is provisional the reply must be complete. See MPEP § 804, subsection I.B.1. For a reply to a non-final Office action, see 37 CFR 1.111(a). For a reply to final Office action, see 37 CFR 1.113(c). A request for reconsideration while not provided for in 37 CFR 1.113(c) may be filed after final for consideration. See MPEP §§ 706.07(e) and 714.13.

Claim Rejections - 35 USC § 103
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 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 1-4, 6, 9-11, 13-15, 18 and 20 are rejected under 35 U.S.C. 103 as being unpatentable over Effenberger US 4402647 in view of Fuller US 20080131273.

Claim 16 is rejected under 35 U.S.C. 103 as being unpatentable over Effenberger US 4402647 and Fuller US 20080131273 as applied to claim 1 above, and further in view of Conrad et al. US 6328527.
Regarding claim 18, Effenberger as modified by Fuller and applied to in the rejection of claim 1 above (Both interpretations), however, they are silent as to:
wherein the intermediate through-hole radius is smaller than the first through-hole radius and larger than the last through-hole radius.
From the same field of endeavor, Conrad teaches:
a first through-hole radius of a first disc (Fig 9: 22 of 12),
a last through-hole radius of a last disc (22 of the furthest right 26 that has the largest opening),
an intermediate through-hole radius of an intermediate disc (22 of a middle 26),
wherein the intermediate through-hole radius (22 of a middle 26) is smaller than the first through-hole radius (22 of 12) and larger than the last through-hole radius (22 of furthest right 26 with the largest opening) (Col 10, line 27-38: The opening of the disc get larger consecutively).
It would have been obvious to one of ordinary skill in the art before the effective filling date of the claimed invention to have modified the disc openings of Effenberger to increase in diameter as taught by Conrad to allow for more fluid to be passed downstream to other spaced apart members where the fluid may be accelerated (Col 9, line 50-63).
This teaching would result in each interpretation of the claimed language above to have “the intermediate through-hole radius is smaller than the first through-hole radius and larger than the last through-hole radius.”
Allowable Subject Matter
Claims 5, 7-8, 12, 17, and 19 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
Claim 5 is rejected under 35 U.S.C. 103 as being unpatentable over Effenberger US 4402647 and Fuller US 20080131273 as applied to claim 1 above, and further in view of Ben- Yosef et al. US 20070081907.
Claim 5 recites “wherein the rotational mount includes an eccentric bearing, and wherein the turbine assembly is configured to rotate about an axis-of- rotation of the eccentric bearing” and is considered allowable subject matter. The rotation of the turbine assembly in an eccentric manner by the eccentric bearing was not found in the prior art from the search. The offset movement of the turbine assembly though the bearing is allowable.
Claim 7 recites “a first foil thickness equal to the first disk thickness” and is considered allowable subject matter. The closest prior art to teach these limitations is Fuller US 20080131273. Fuller teaches the foils (3) having a thickness and disc (1) having a thickness. However, Fuller and prior art found in the search does not teach the thicknesses being equal.
Claim 12 recites ““wherein a first foil incircle radius of a first foil incircle defined by the plurality of first foils is equal to the first through-hole radius” and is considered allowable subject matter. The closest prior art to teach these limitations is Fuller US 20080131273. The limitation of “a first foil incircle radius of a first foil incircle defined by the plurality of first foils is equal to the first through-hole radius” essentially teaches that the foils are located at the inner circle of the disk touching the through hole radius. The prior art of record, such as Fuller, only teaches that the airfoils are within the disc and not touching the through hole or inner opening.
Claim 17 recites” wherein a first foil incircle radius of a first foil incircle defined by the plurality of first foils is equal to the last through-hole radius and a second foil incircle radius of a second foil incircle defined by the plurality of second foils is equal to the last through-hole radius” ” and is considered allowable subject matter. The closest prior art to teach these limitations is Fuller US 20080131273. This limitation essentially teaches that the foils are located at the inner circle of the disk touching the through hole radius of each of the disc. The prior art of record, such as Fuller, only teaches that the airfoils are within the disc and not touching the through hole or inner opening.
Claims 8 depend off of a claim with allowable subject matter, therefore making them allowable.
Claim 19 distinguishes itself in the same manner as in claim 7, therefore allowable.
As allowable subject matter has been indicated, applicant's reply must either comply with all formal requirements or specifically traverse each requirement not complied with. See 37 CFR 1.111(b) and MPEP § 707.07(a).
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Berkson et al. US 20190055843 discloses a similar foil and disc arrangement to the applicants. Shoffler US 9951620 and Sarmiento US 20170051 757 discloses an arrangement that could read onto the foil and disc arrangement of claim 7. Gilliam US 20120014779, Possell US 4347032 and Dial US 20050019154 discloses a similar fastener as the present application.
