`
`DETAILED ACTION
`
`Continued Examination Under 37 CFR 1. 1 14
`
`A request for continued examination under 37 CFR 1.114, including the fee set
`
`forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this
`
`application is eligible for continued examination under 37 CFR 1.114, and the fee set
`
`forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action
`
`has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on May 10,
`
`2012 has been entered.
`
`Examiner has withdrawn the objections to the specification and claims set forth in
`
`the previous Office Action. Examiner has modified the previous grounds of rejection in
`
`response to the amendments to the claims.
`
`Terminal Disclaimer
`
`The terminal disclaimer filed on January 24, 2012 disclaiming the terminal portion
`
`of any patent granted on this application which would extend beyond the expiration date
`
`of 8,079,413 has been reviewed and is NOT accepted.
`
`The filing date listed on the terminal disclaimer (July 27, 2011) is incorrect. The
`
`correct filing date is July 29, 2011.
`
`Claim Objections
`
`Claim 1
`
`is objected to because of the following informalities: The section
`
`beginning "pulling on the setting rod..." in line 12 is unclear because it appears to recite
`
`a method step in an apparatus claim. Examiner suggests inserting --wherein-- between

`
`Art Unit: 3676
`
`"section," and "pulling" and changing "acting" to --acts--. Appropriate correction is
`
`required.
`
`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
`
`obviousness—type 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); and 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 a nonstatutory
`
`double patenting ground provided the conflicting application or patent either is shown to
`
`be commonly owned with this application, or claims an invention made as a result of
`
`activities undertaken within the scope of a joint research agreement.

`
`Effective January 1, 1994, a registered attorney or agent of record may sign a
`
`terminal disclaimer. A terminal disclaimer signed by the assignee must fully comply with
`
`37 CFR 3.73(b).
`
`Claims 41-47, 51, and 52 are rejected on the ground of nonstatutory
`
`obviousness-type double patenting as being unpatentable over claims 1-6 of U.S.
`
`Patent No. 8,079,413. Although the conflicting claims are not identical, they are not
`
`patentably distinct from each other because the claims in the ‘41 3 patent are narrower
`
`than the pending claims, and therefore the pending claims are fully encompassed by the
`
`patented claims and obviously directed to the same invention.
`
`This is a provisional obviousness-type double patenting rejection because the
`
`conflicting claims have not in fact been patented.
`
`Claim Rejections - 35 USC § 103
`
`The following is a quotation of 35 U.S.C. 103(a) which forms the basis for all
`
`obviousness rejections set forth in this Office action:
`
`(a) A patent may not be obtained though the invention is not identically disclosed or described as set
`forth in section 102 of this title, if the differences between the subject matter sought to be patented and
`the prior art are such that the subject matter as a whole would have been obvious at the time the
`invention was made to a person having ordinary skill in the art to which said subject matter pertains.
`Patentability shall not be negatived by the manner in which the invention was made.
`
`The factual inquiries set forth in Graham v. John Deere Co., 383 U.S. 1, 148
`
`USPQ 459 (1966), that are applied for establishing a background for determining
`
`obviousness under 35 U.S.C. 103(a) are summarized as follows:
`
`1.
`2.
`3.
`4.
`
`Determining the scope and contents of the prior art.
`Ascertaining the differences between the prior art and the claims at issue.
`Resolving the level of ordinary skill in the pertinent art.
`Considering objective evidence present in the application indicating
`obviousness or nonobviousness.

`
`Art Unit: 3676
`
`Claims 1, 8, 11, 24, 41, 43, 44, and 51 are rejected under 35 U.S.C. 103(a) as
`
`being unpatentable over Bonner (US 3,160,209) in view of Fripp et al. (US
`
`7,428,922, hereinafter Fripp).
`
`With regard to claim 1, Bonner discloses a down hole well tool comprising
`
`a mandrel (82) having a first passage therethrough;
`
`a slips/seal section (95, 93, 91, etc.) movable on an exterior of the mandrel from
`
`a running in position to an expanded position for sealing against a production string; and
`
`a setting assembly (70, 84, 83, etc.) for assisting in moving the slips/seal section
`
`from the running in position to the expanded position, the setting assembly including
`
`a setting device (83), rigid with the mandrel, having a second passage
`
`therethrough, and
`
`a setting rod engaged with the second passage (via a pin 85), pulling on the
`
`setting rod acting to pull the engaged sections apart (by breaking the pin 85), expand
`
`the slips/seal section into sealing engagement with the production string and remove
`
`the setting rod from the mandrel, the arrangement of the setting device and setting rod
`
`being that removal of the setting rod from the tool opens the first and second passages,
`
`the setting device remaining rigid with the mandrel upon removal of the setting rod (see
`
`Figs.).
`
`Bonner fails to disclose the connection between the setting rod and the setting
`
`device being a shearable thread connection. Bonner instead discloses a shear pin.
`
`Fripp teaches the functional equivalence of shear pins and shear threads for
`
`release mechanisms in downhole tools (column 7, lines 6-16).

`

`
`Application/Control Number: 12/317,497
`
`Page 6
`
`Art Unit: 3676
`
`It would have been considered obvious to one of ordinary skill in the art, at the
`
`time the invention was made, to have modified Bonner such that the shear pin
`
`connection was replaced with a shearable thread connection, since such a modification
`
`would have amounted to the mere substitution of one well-known release mechanism
`
`for another, and would have yielded predictable results, as evidenced by Fripp.
`
`Furthermore, in combination, Bonner and Fripp discloses an unthreaded section (i.e.
`
`between the part that's already threaded in Bonner and the added threads which
`
`replace the pin of Bonner) that would necessarily be larger in diameter than the
`
`threaded section in order for the setting rod to be removed from above as required.
`
`With regard to claim 8, the first passage extends completely through the mandrel
`
`and slips/seal section (see Figs. of Bonner).
`
`With regard to claim 11, Bonner in view of Fripp discloses a first end and a
`
`second end, the down hole tool being adapted to receive the setting rod through the first
`
`end and wherein the unthreaded section is between the second end and the threaded
`
`section (see Figs. of Bonner and discussion above with respect to claim 1).
`
`With regard to claim 24, the setting device (83) is connected to the mandrel (82).
`
`With regard to claim 41, Bonner discloses a plug for isolating a wellbore,
`
`comprising
`
`a mandrel (82) having a first end and a second end and a passage between the
`
`mandrel;
`
`at least one malleable element (95) disposed about the mandrel;
`
`at least one slip (89) disposed about the mandrel;
`
`MEGCO EX. 1021
`
`MEGCO Ex. 1021
`
`
`
`Application/Control Number: 12/317,497
`
`Page 7
`
`Art Unit: 3676
`
`at least one conical member (93) disposed about the mandrel; and
`
`an insert (83) threadably engaging the mandrel through a threaded connection
`
`proximate the second end of the mandrel and adapted to receive a setting tool (84) that
`
`enters the mandrel through the first end thereof, wherein:
`
`the insert providing a passage thereinto;
`
`the insert adapted to engage the setting tool (via shearable pin 85); and
`
`the insert adapted to release the setting tool when exposed to a predetermined
`
`axial force, thereby providing a passageway through the mandrel and into the insert.
`
`Bonner fails to disclose the connection between the setting rod and the setting
`
`device being a shearable thread connection. Bonner instead discloses a shear pin.
`
`Fripp teaches the functional equivalence of shear pins and shear threads for
`
`release mechanisms in downhole tools (column 7, lines 6-16).
`
`It would have been considered obvious to one of ordinary skill in the art, at the
`
`time the invention was made, to have modified Bonner such that the shear pin
`
`connection was replaced with a shearable thread connection, since such a modification
`
`would have amounted to the mere substitution of one well-known release mechanism
`
`for another, and would have yielded predictable results, as evidenced by Fripp.
`
`Furthermore, in combination with Fripp, Bonner discloses the threaded connection
`
`between the insert (83) and the mandrel (82) being unshearable, since Figs. 2C and 3
`
`show the connection between the insert and the setting tool shearing, but notthe
`
`connection between the insert and the mandrel.

`
`Art Unit: 3676
`
`With regard to claim 43, the mandrel is at least capable of receiving a ball which
`
`could seat on the upper end of the mandrel and thereby restrict flow in at least one
`
`direction through the body.
`
`With regard to claim 44, the predetermined axial force to release the setting tool
`
`is less than an axial force required to break the mandrel.
`
`With regard to claim 51, the mandrel passage is of a first diameter and the insert
`
`passage is substantially the same diameter as the mandrel passage (see Bonner, Fig.
`
`2G).
`
`Claim 4, 5, and 47 are rejected under 35 U.S.C. 103(a) as being unpatentable
`
`over Bonner in view of Fripp as applied to claims 1 and 41 above, and further in
`
`view of Turley et al. (US 7,690,436, hereinafter Turley).
`
`Bonner in view of Fripp discloses an inlet (i.e. at the upper end of mandrel 82 of
`
`Bonner) which is capable of seating a ball. However, the inlet is not tapered, and
`
`Bonner does not disclose a ball being seated within the inlet.
`
`Turley discloses a downhole plug (Fig. 7C) comprising a tapered inlet (372)
`
`for a ball (370) to seal against to prevent downward flow.
`
`It would have been considered obvious to one of ordinary skill in the art, at the
`
`time the invention was made, to have provided the apparatus of Bonner in view of Fripp
`
`with a tapered inlet as disclosed by Turley, since this would have enabled additional
`
`functionality for the plug, such as frac plug capability (see Turley, column 6, lines 18-
`
`39).

`
`Claims 45 and 46 are rejected under 35 U.S.C. 103(a) as being unpatentable
`
`over Bonner in view of Fripp as applied to claim 41 above, and further in view of
`
`Slup et al. (US 6,708,770, hereinafter Slup).
`
`Bonner in view of Fripp fails to disclose an anti-rotation feature comprising a
`
`taper or mule shoe.
`
`Slup discloses a mandrel comprising a tapered anti-rotation feature (432—see
`
`Figs. 22 and 23).
`
`It would have been considered obvious to one of ordinary skill in the art, at the
`
`time the invention was made, to have modified Bonner in view of Fripp to have an anti-
`
`rotation feature at the second end of the device, in order to “rotationally lock...with
`
`another abutting plug assembly without the need for a third component such as a key"
`
`(Slup, column 18, line 65).
`
`Claim 52 is rejected under 35 U.S.C. 103(a) as being unpatentable over
`
`Bonner in view of Fripp as applied to claim 41 above, and further in view of
`
`Streich et al. (US 5,224,540, hereinafter Streich).
`
`Bonner mentions that the plug is "easily drillable," but is silent as to the actual
`
`material composition of the insert (column 1, lines 24-27).
`
`Streich discloses brass being a well known material for components of
`
`drillable bridge plugs (column 1, lines 46-54).
`
`It would have been considered obvious to one of ordinary skill in the art, at the
`
`time the invention was made, to have modified Bonner such that the insert was formed

`
`of brass, as Bonner's plug is designed to be drillable, and Streich et al. teach that brass
`
