OFFICE ACTION:
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 .
Status of the Application
Claims 1-20 are pending and have been examined in this application. This communication is the first action on the merits. As of the date of this application, the Information Disclosure Statement(s) (IDS) filed on 06/27/2024 has/have been taken into account.
Priority
Receipt is acknowledged of certified copies of papers required by 37 CFR 1.55.
Drawings
The drawings are objected to under 37 CFR 1.83(a).  The drawings must show every feature of the invention specified in the claims.  Therefore, the locking mechanism detailed in claim 14 must be shown or the feature(s) canceled from the claim(s).  No new matter should be entered.
Corrected drawing sheets in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. Any amended replacement drawing sheet should include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. The figure or figure number of an amended drawing should not be labeled as “amended.” If a drawing figure is to be canceled, the appropriate figure must be removed from the replacement sheet, and where necessary, the remaining figures must be renumbered and appropriate changes made to the brief description of the several views of the drawings for consistency. Additional replacement sheets may be necessary to show the renumbering of the remaining figures. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either “Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). 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 Objections
Claim 7 is objected to because of the following informalities: Claim 7 recites “the angle between”. This should read “an angle between” (emphasis added).  Appropriate correction is required.
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 1-20 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 1 and 20 each recite “the working plane extending radially from the compressible sleeve’s longitudinal axis, and parallel to the compressible sleeve’s longitudinal axis”. – It is unclear how a plane extending radially from a longitudinal axis can also be parallel to said axis as the recited origin point of the plane is the axis. In other words, the imaginary plane will intersect the longitudinal axis and therefore cannot be parallel to it.
Claim 10 recites the limitation the two lever arm sides in lines 1-2.  There is insufficient antecedent basis for this limitation in the claim.
Claim 11 recites the limitation the two lever arm sides in line 2.  There is insufficient antecedent basis for this limitation in the claim.
Claim 13 recites the limitation the nut in line 2.  There is insufficient antecedent basis for this limitation in the claim.
Claims 2-9, 12, and 14-20 are rejected based on their dependency.
Allowable Subject Matter
Claims 1-20 would be allowable if rewritten or amended to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action.
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. See PTO-892 for cited references.

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 .
EXAMINER'S AMENDMENT
An examiner’s amendment to the record appears below. Should the changes and/or additions be unacceptable to applicant, an amendment may be filed as provided by 37 CFR 1.312. To ensure consideration of such an amendment, it MUST be submitted no later than the payment of the issue fee.
Authorization for this examiner’s amendment was given in an interview with Ryan Alley on 10/22/2025.
The application has been amended as follows:
In The Claims:
1. 	(Currently Amended) A post socket comprising:
a housing;
a compressible sleeve within the housing, the sleeve arranged to receive at least a portion of a post therein, wherein the sleeve comprises a grip section, the grip section being adjustably moveable between a first grip position in which the sleeve has a first internal width and a second grip position in which the sleeve has a second internal width, the second internal width being less than the first internal width;
a lever arm rotatably attached to the housing at a first pivot point, the lever arm configured to rotate in a working plane, the working plane extending radially from and coplanar with the compressible sleeve’s longitudinal axis; and
an actuator configured to rotate the lever arm around the first pivot point;
wherein the grip section is rotatably attached to the lever arm at a second pivot point, the lever arm arranged to move the grip section, from the first grip position to the second grip position, to grip and thus retain at least a portion of a post within the sleeve.
…
8. 	(Currently Amended) The post socket of claim 1, wherein the grip section comprises a concave surface, and two grip section sides extending away from the concave surface in a direction parallel to [[a]] the working plane
…
20. 	(Currently Amended) A system for securing a post, the system comprising:
a post; and
a post socket comprising:
a housing;
a compressible sleeve within the housing, the sleeve arranged to receive at least a portion of the post therein, wherein the sleeve comprises a grip section, the grip section being adjustably moveable between a first grip position in which the sleeve has a first internal width and a second grip position in which the sleeve has a second internal width, the second internal width being less than the first internal width;
a lever arm rotatably attached to the housing at a first pivot point, the lever arm configured to rotate in a working plane, the working plane extending radially from and coplanar with the compressible sleeve’s longitudinal axis; and
an actuator configured to rotate the lever arm around the first pivot point; wherein the grip section is rotatably attached to the lever arm at a second pivot point, the lever arm arranged to move the grip section, from the first grip position to the second grip position, to grip and thus retain at least a portion of the post within the sleeve.
Reasons for Allowance
The following is an examiner’s statement of reasons for allowance:
Simmons (US 2020/0190843) discloses a post socket with a housing, compressible sleeve with a grip section, lever arm, and actuator as claimed. However, its lever arm rotates in a working plane that is not extending radially from the compressible sleeves longitudinal axis and modification to that orientation would destroy its mechanism. Friedman (US 3,604,734) discloses a sleeve with a grip section but its sleeve is not within a housing and it lacks a lever arm. For these reasons, and as no additional references have been found which read on the recited subject matter, the claims have been found to be allowable over the prior art.
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.”
