OFFICE ACTION:
DETAILED ACTION
This communication is a final office action on the merits and in response to amendments filed on 8/26/2024. All currently pending claims have been considered below. The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Response to Amendment
Applicant's amendments are sufficient to overcome the prior 112(b) rejections. However claims 10 & 11 are now rendered indefinite due to their limitations being redundantly recited in parent claim 1. Further, Applicant states that corrected drawings with an amended Fig. 2. The examiner is respectfully obliged to note that this corrected drawing does not appear to have made it into Applicant's communication.
Drawings
Figure 2 should be designated by a legend such as --Prior Art-- because only that which is old is illustrated. See MPEP § 608.02(g). The specification describes figure 2 as a conventional geothermal power generation system (¶ 19).
Corrected drawings in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. The replacement sheet(s) should be labeled “Replacement Sheet” in the page header (as per 37 CFR 1.84(c)) so as not to obstruct any portion of the drawing figures. If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance.
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 10-12 are rejected under 35 U.S.C. 112(b) as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor, regards as the invention.
Claim 10 recites The process of claim 9, further comprising after determining that the casing reaches a target depth, stopping the flow of the first fluid into the borehole. However claim 1 has been amended to recite after the casing is sunk to a desired level within the borehole, ceasing the flow of the first fluid. These appear to be redundant recitations. It is unclear in light of the specification how or if the target depth and related method step in claim 10 differ from the desired level and related method step now in claim 1. Claims 11 & 12 depend from claim 10.
Similarly, claim 11 only recites features now found in parent claim 1. Claim 12 depends from claim 11.
Allowable Subject Matter
Claims 1-9 & 13-20 are allowed.
The following is an examiner’s statement of reasons for allowance: The independent claims have been amended to recite inter alia after the casing is sunk to a desired level within the borehole, ceasing the flow of the first fluid into the borehole thereby causing the rock layer maintained around the portion of the borehole within the magma reservoir to remelt such that magma contacts casing located within the magma reservoir.
The two closest prior art documents are the NPL Magma Energy Research Project, 1982, a copy of which was provided by Applicant in the IDS filed 7/31/2023 and US 11,913,679 (Lindberg), available as prior art under 102(a)(2).
In both cases, the prior art does not teach nor suggest the above limitations.
The NPL teaches an interruption (> a few minutes) of coolant flow down the drill string - commensurate with the first fluid in the present claims- while drilling results in hole loss at best and bit and drill string lost at worst. A redundant cooling system would be required for deep drilling (page 16 as-numbered in the NPL, right column, last paragraph). This clearly suggests that stopping cooling fluid flow is bad and the loss of the surrounding rock layer formed by the cooling fluid is undesirable.
Lindberg teaches geothermal systems and methods with an underground magma chamber (title) and teaches forming and maintaining a rock layer (The surface 438 may be hardened magma (e.g., rock with or without glassy material) that forms via heat transfer between the magma 412 and the pressurization fluid 442 - col 8:13-16, figs 4C & 4D) by cooling the magma with a cooling fluid (pressurization fluid 442 - ibid). However, similar to the NPL, Lindberg teaches that it is desirable to maintain this layer with the subsequent heat transfer fluid (fig 4D). At best, Lindberg teaches During subsequent use of the underground chamber 440 (see FIGS. 4D and 6), all or a portion of the surface 438 may be allowed to be heated and melt to increase thermal contact between fluid in the underground chamber 440 and the magma 412 (col 8:23-27), but the underground chamber 440 is still present (as quoted here) and therefore the magma is not taught as contacting the casing. Nor is this commensurate with the two fluid flow currently recited in the present claims.
Any comments considered necessary by applicant must be submitted no later than the payment of the issue fee and, to avoid processing delays, should preferably accompany the issue fee.  Such submissions should be clearly labeled “Comments on Statement of Reasons for Allowance.”
Conclusion
Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action.  Accordingly, THIS ACTION IS MADE FINAL.  See MPEP § 706.07(a).  Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a).
A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action.  In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any extension fee pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action.  In no event, however, will the statutory period for reply expire later than SIX MONTHS from the date of this final action.

APPLICANT REBUTTAL: REMARKS
I. DISPOSITION OF THE CLAIMS
. Applicant respectfully requestsreconsideration of the present application in view of the foregoing amendments and the following remarks.
II. OBJECTIONS TO THE DRAWINGS
The Office Action objects to FIG. 2 of the present application for not including a designation as "Prior Art". In response, a Replacement Sheet is submitted herewith setting forth an amended FIG. 2 having the designation as "Prior Art". No new matter is added. Accordingly, it is believed that this objection has been overcome, and Applicant respectfully requests withdrawal of the objection.
III. REJECTIONS UNDER 35 U.S.C. J 112
The Office Action rejects claims 1-12 under 35 U.S.C. §112(b) as allegedly being indefinite. In particular, the Office Action objects to elements in claims 1, 8, 11 and 20 for failing to recite additional elements deemed necessary to understanding the scope of the claims. In response, Applicant has amended claims 1 and 8 as suggested by the Examiner. No new matter is added. Accordingly, it is believed that these rejections have been overcome, and Applicant respectfully requests withdrawal of the rejections. IV. REJECTIONS UNDER 35 U.S.C. J 102
The Office Action rejects claims 13, 14 and 16-20, of which claim 13 is independent, under 35 U.S.C. § 102 as allegedly being anticipated by U.S. Patent 3,398,794 to Fox. In response, Applicant has amended independent claim 13 to recite an element included in original independent claim 1 and which is acknowledged as not being disclosed in Fox. Specifically, independent claim 13 has been amended to recite "providing a flow of a first fluid into the borehole
to cause a rock layer to be formed and maintained from magma around a portion of
the borehole located within the magma reservoir".
Accordingly, it is believed that this rejection has been overcome, and Applicant therefore respectfully requests withdrawal of the rejection.
V. REJECTIONS UNDER 35 U.S.C. § 103
The Office Action rejects claims 1-12 and 15, of which claim 1 is independent, under 35 U.S.C. § 103 as allegedly being obvious and thus unpatentable over U.S. Patent 3,398,794 to Fox in view of the article entitled "Magma Energy Research Project", by Colp (1982), hereinafter "Colp". In response, Applicant has amended independent claims 1 and 13 to recite that after the casing is sunk using the flow of the second fluid to a desired level within the borehole, the flow
of the first fluid into the borehole is ceased, which thus causes the rock layer previously formed by the cooling of the magma at the bottom of the borehole to remelt such that magma contacts casing located within the magma reservoir.
In contrast, Fox teaches that the fluid within the casing is used to equalize the pressure imparted on the exterior surface of the casing by the fluid in the wellbore (outside of the casing) when the casing is lowered into the borehole. As such, Fox does not teach providing a flow of the fluid in the borehole as the casing is lowered into the borehole. Importantly, this is because Fox does not teach its technique of lowering a casing in a borehole that has been drilled into a magma reservoir. This is clear because without a constant flow of cooling ("first") fluid into the borehole located within a magma reservoir, the liquid state of the magma would collapse the borehole prior to the casing being sunk into the borehole. Specifically, the nonflowing fluid in
the borehole disclosed in Fox would very quickly boil from the heat of the magma and collapse the borehole if the borehole in Fox were formed into a magma reservoir as recited in the present claims. Consequently, there can be no teaching or suggestion in Fox to cease the flow of the first fluid once the casing is placed at a depth partly within a magma reservoir such that the rock layer originally formed from magma cooled by the flow of the first fluid remelts and the magma surrounds and contacts the portion of the casing within the magma reservoir, as recited in the presently amended claims.
Moreover, the addition of Colp with Fox does not cure this deficiency of Fox. Specifically, while Colp may disclose the cooling of magma into rock that may be drilled, Colp also does not disclose or suggest that a once a casing is floated down to a depth partly within a magma reservoir, the cooling fluid is ceased such that the rock layer originally formed from magma cooled by the flow of that fluid remelts and the magma surrounds and contacts the portion of the casing within the magma reservoir, as recited in the presently amended claims. As a result, since neither Fox nor Colp discloses or suggests these elements of the presently
amended claims, even the combination of Fox with Colp does not teach or suggest these
elements. Accordingly, Applicant respectfully asserts that the combination of Fox and Colp does not teach or suggest all of the elements of independent claims 1 and 13, as presently amended. Thus, the claims dependent on these amended independent claims are also not disclosed or
suggested by the combination of Fox and Colp. Applicant, therefore, respectfully requests that the rejection of these claims be withdrawn.
VI. REQUEST FOR EVIDENTIARY SUPPORT
Should any of the above asserted rejections be maintained, Applicant respectfully requests appropriate evidentiary support. Additionally, if the Examiner intends to rely upon "common knowledge" or "well known" principles to establish the rejection, Applicant requests that a reference be provided in support of this position pursuant to MPEP § 2144.03. Furthermore, to the extent that the Examiner maintains any rejection based on an "Official Notice" or other information within the Examiner's personal knowledge, Applicant respectfully requests that the Examiner cite a reference as documentary evidence in support of this position or
provide an affidavit in accordance with MPEP § 2144.03 and 37 C.F.R. 1.104(d)(2). VII. NO WAIVER
All of Applicant's arguments and amendments are without prejudice or disclaimer. Additionally, Applicant has merely discussed example distinctions from the cited references. Other distinctions may exist, and Applicant reserves the right to discuss these additional distinctions in a later Response or on Appeal, if appropriate. By not responding to additional statements made by the Examiner, either in the present Office Action, any prior communication from the Office, or any future communication from the Office, Applicant does not acquiesce to any such additional statements, such as, for example, any statements relating to what is or is not disclosed or suggested in any reference, what would be obvious or not obvious to a person of ordinary skill in the art, or any statements made as reasons for allowance of any claim in the present application.
CONCLUSION
