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 .
Election/Restrictions
Applicant’s election without traverse of Species A in the reply filed on 05/15/2026 is acknowledged. Claims 30-35 are withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to a nonelected species, there being no allowable generic or linking claim.
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.

Claims 19-24 and 28-29 are provisionally rejected (the withdrawn claims will be examined if rejoined) on the ground of nonstatutory double patenting as being unpatentable over claim 15-20 and 22-23 of copending Application No. 18698318 (reference application) in view of Pearce (US20170362900A1).
The difference between the instant applicant and the reference application is that the reference application only requires two drilling segments, and the instant application claims require three.
Pearce teaches a drilling shaft having two (Figure 7) or three (Figure 19) drilling segments that are equally spaced from one another about the circumference of the tool and have the required shape/configuration as claimed in the independent claims (See rejection of Claim 19 below under 35 USC 102).

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 19-29 and 36 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 19 recites “the circumference”. There is insufficient antecedent basis for this limitation.
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:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.
(a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention.
Claims 19-29 and 36 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Pearce (US20170362900A1).
Claim 19
Pearce teaches a drilling shaft (20) having a cylinder (Figure 3) with a longitudinal axis (12), wherein the cylinder has, in a plane perpendicular to the longitudinal axis, an outside diameter (Figure 3 shows the shank (20) has an outer diameter.), an inside diameter (Figure 3 shows an interior space defined by an inside diameter.) and a shaft width (The shaft width is the difference between the inner and outer diameters.), and a plurality of drilling segments (Figure 19 shows three drilling segments (234A/B/C).) spaced apart from one another in a circumferential direction (Figure 19) and fastened by an underside to the drilling shaft (Figure 17 shows the underside of the segments (234) is secured to the shaft (220).), wherein the plurality of drilling segments include a first drilling segment with a first inner lateral surface having a first inner distance from the longitudinal axis perpendicular to the longitudinal axis, a second drilling segment with a second inner lateral surface having a second inner distance from the longitudinal axis perpendicular to the longitudinal axis, and a third drilling segment with a third inner lateral surface having a third inner distance from the longitudinal axis perpendicular to the longitudinal axis (Figure 19 shows a plan/top down view of the drilling segments where the inner surfaces have a distance to the center (210).), the first inner distance varying between a first maximum value and a first minimum value and having precisely one first absolute minimum value (274) over the circumference of the first drilling segment, the second inner distance being greater than or equal to the first absolute minimum value over the circumference of the second drilling segment, and the third inner distance being greater than or equal to the first absolute minimum value over the circumference of the third drilling segment. (Figure 19 shows that the drilling segments (234) make up portions of a cylinder. The circumference of each of the segments extends between the edges (236 to 238). The minimum value of the segment is located at the medial edge (274). Each of the segments (234) has a location where a second/third inner distance is greater than or equal to the medial edge (274) distance.)
Claim 20
Pearce teaches the drill bit as recited in claim 19 wherein the first inner distance has two first maximum values over the circumference of the first drilling segment, wherein the first absolute minimum value is arranged between the first maximum values in the circumferential direction. (Figure 19 shows the cross section of the segments (234) is such that there are two maximum values at 236 and 238, and that the minimum value (274) is located between the locations of the maximum values.)
Claim 21
Pearce teaches the drill bit as recited in claim 19 wherein the first inner distance follows, over the circumference of the first drilling segment, a strictly monotonic profile in the region of the first absolute minimum value. (The term monotonic is interpreted as value either increasing or decreasing constantly. Figure 19 shows that the location of the minimum value(s) (274) is curved such that there is not a significant area of constant value for the inner distance.)
Claim 22
Pearce teaches the drill bit as recited in claim 21 wherein the second inner distance varies between a second maximum value and a second minimum value and has precisely one second absolute minimum value over the circumference of the second drilling segment. (Figure 19 shows that the drilling segments (234) make up portions of a cylinder. The circumference of each of the segments extends between the edges (236 to 238). The minimum value of the segment is located at the medial edge (274). The maximum value is located at the edges (236, 238).)
Claim 23
Pearce teaches the drill bit as recited in claim 22 wherein the second inner distance has two second maximum values over the circumference of the second drilling segment, wherein the second absolute minimum value is arranged between the second maximum values in the circumferential direction. (Figure 19 shows the cross section of the segments (234) is such that there are two maximum values at 236 and 238, and that the minimum value (274) is located between the locations of the maximum values.)
Claim 24
Pearce teaches the drill bit as recited in claim 22 wherein the second inner distance follows, over the circumference of the second drilling segment, a strictly monotonic profile in the region of the second absolute minimum value. (The term monotonic is interpreted as value either increasing or decreasing constantly. Figure 19 shows that the location of the minimum value(s) (274) is curved such that there is not a significant area of constant value for the inner distance.)
Claim 25
Pearce teaches the drill bit as recited in claim 22 wherein the third inner distance varies between a third maximum value and a third minimum value and has precisely one third absolute minimum value over the circumference of the third drilling segment. (Figure 19 shows that the drilling segments (234) make up portions of a cylinder. The circumference of each of the segments extends between the edges (236 to 238). The minimum value of the segment is located at the medial edge (274). The maximum value is located at the edges (236, 238).)
Claim 26
Pearce teaches the drill bit as recited in claim 25 wherein the third inner distance has two third maximum values over the circumference of the third drilling segment, wherein the third absolute minimum value is arranged between the third maximum values in the circumferential direction. (Figure 19 shows the cross section of the segments (234) is such that there are two maximum values at 236 and 238, and that the minimum value (274) is located between the locations of the maximum values.)
Claim 27
Pearce teaches the drill bit as recited in claim 25 wherein the third inner distance follows, over the circumference of the third drilling segment, a strictly monotonic profile in the region of the third absolute minimum value. (The term monotonic is interpreted as value either increasing or decreasing constantly. Figure 19 shows that the location of the minimum value(s) (274) is curved such that there is not a significant area of constant value for the inner distance.)
Claim 28
Pearce teaches the drill bit as recited in claim 19 wherein the first inner lateral surface is formed as a portion of a first cylinder, the second inner lateral surface is formed as a portion of a second cylinder, and the third inner lateral surface is formed as a portion of a third cylinder. (The cross sectional view as shown in Figure 19 teaches that the drilling segments make up portions of cylinder(s) (See annotation below), and therefore the inner surfaces are formed of portions of said cylinder(s).)

Claim 29
Pearce teaches the drill bit as recited in claim 28 wherein the first cylinder has a first base surface differing from a circular shape, or the second cylinder has a second base surface differing from a circular shape, or the third cylinder has a third base surface differing from a circular shape. (Applicant does not assign “base surface” an item number nor call out what the base surface is in the drawings. There are multiple surfaces on the drilling segments (234) that are not circular and can qualify as a “base surface” due to the broad nature of the claim and lack of explicit illustration in the application.)
Claim 36
Pearce teaches the drill bit as recited in claim 19 wherein the first drilling segment, second drilling segment and third drilling segment are of identical design. (Figure 19 shows the shape/size of the drilling segments (234) is equal. ¶0092 teaches the height can be equal. ¶0121 teaches the angles used on the drilling segments can be equal. ¶0054 teaches a length measurement of the inner surfaces of the segments (34) can be equal.)
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure can be found on the PTO-892 Form.
