DETAILED ACTION
The present application is being examined under the pre-AIA first to invent provisions.
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 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)(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 59-60 are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Li (US 20240424366 A1).
Regarding claim 59, Li teaches 59. (New) A pickleball paddle, comprising: a front surface; a back surface opposing the front surface; a core disposed between the front surface and the back surface; See Fig. 2B; (112)(118)(115) wherein the front and back surfaces sandwich the core portion., a frame disposed about at least a head portion of the pickleball paddle along an edge portion thereof, the frame at least partially disposed between the front surface and the back surface along the edge portion; See Fig. 2B; (151) which shows a frame 151 being placed around the perimeter of the sandwich structure., a gap formed in the core, the gap disposed substantially adjacent to the frame along at least a portion of the head portion of the pickleball paddle; and See Fig. 2B which shows a gap where the additional material is placed around the core., a first filler disposed within at least a section of the gap. See Fig. 2B; (121) wherein the item 121 may be considered the filler.
Regarding claim 60, Li teaches 60. (New) The pickleball paddle of claim 59, wherein the first filler includes a material structurally configured to absorb vibrations caused by striking a ball with one or more of the front surfaces and the back surface of the pickleball paddle. See [0185+].
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 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 of this title, 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.
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. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.
4. Considering objective evidence present in the application indicating obviousness or nonobviousness.
The Supreme Court in KSR International Co. v. Teleflex Inc., 550 U.S. 398, 82 USPQ2d 1385, 1395-97 (2007) identified a number of rationales to support a conclusion of obviousness which are consistent with the proper “functional approach” to the determination of obviousness as laid down in Graham. Exemplary rationales that may support a conclusion of obviousness include:
(A) Combining prior art elements according to known methods to yield predictable results;
(B) Simple substitution of one known element for another to obtain predictable results;
(C) Use of known technique to improve similar devices (methods, or products) in the same way;
(D) Applying a known technique to a known device (method, or product) ready for improvement to yield predictable results;
(E) “Obvious to try” – choosing from a finite number of identified, predictable solutions, with a reasonable expectation of success;
(F) Known work in one field of endeavor may prompt variations of it for use in either the same field or a different one based on design incentives or other market forces if the variations are predictable to one of ordinary skill in the art;
(G) Some teaching, suggestion, or motivation in the prior art that would have led one of ordinary skill to modify the prior art reference or to combine prior art reference teachings to arrive at the claimed invention.
The notations noted below apply to all rejections: In as much structure set forth by the applicant in the claims, the device is capable of use in the intended manner if so desired (See MPEP 2112). It should be noted that a recitation of the intended use of the claimed invention must result in a structural difference between the claimed invention and the prior art in order to patentably distinguish the claimed invention from the prior art. If the prior art structure is capable of performing the intended use, it meets the claim limitations. In a claim drawn to a process of making, the intended use must result in a manipulative difference as compared to the prior art. See In re Casey, 370 F.2d 576, 152 USPQ 235 (CCPA 1967) and In re Otto, 312 F.2d 937, 939, 136 USPQ 458, 459 (CCPA 1963). The intended use defined in the preamble and body of the claim breathes no life and meaning structurally different than that of the applied reference.
Claims 41-43, 45-51, 55-58 are rejected under 35 U.S.C. 103 as being unpatentable over Li (US 20240424366 A1) in view of Fox (US 20170136325 A1).
Regarding claim 41, Li teaches 41. (New) A method of making a pickleball paddle, the method comprising: forming a sandwich structure including a front surface, a back surface, and a core disposed in-between the front surface and the back surface; See Fig. 2B; (112)(118)(115) wherein the front and back surfaces sandwich the core portion., removing, using tooling, at least a portion of the core to form a gap between the front surface and the back surface; See Fig. 2B although the disclosure of the tooling isn't explicitly included in the disclosure the use of tooling to remove the material where 121 sits in Fig. 2B is an obvious manufacturing process which could easily be included to achieve the desired product. Other means such as using predefined sizes could be used to achieve the desired size to allow the space for 121 to placed., inserting a first filler within at least a portion of the gap; and See Fig. 2B; (121) wherein the item 121 may be considered the filler., placing a frame about at least a portion of a perimeter of the sandwich structure. See Fig. 2B; (151) which shows a frame 151 being placed around the perimeter of the sandwich structure.
Fox does teach what the primary reference is silent on including commercially practicable manufacturing methods. See [0044+].

It would have been obvious to one of ordinary skill in the art, at the date of the effective filing, to modify Li with Fox to allow a paddle to be manufactured with commercially practible way.
Regarding claim 51, Li teaches 51. (New) The method of claim 41, wherein the frame is placed about the entire perimeter of the sandwich structure. See Fig. 2B.
Regarding claim 55, Li teaches 55. (New) The method of claim 41, wherein the first filler includes at least one of pressurized air, a polymer, a thermoplastic material, a thermoset material, a thermoplastic elastomer, an elastomer, a rubber, a foam, a polymeric foam, and an expandable material. See [0070+].
Regarding claim 56, Li teaches 56. (New) The method of claim 41, wherein the frame includes at least one of carbon, glass, fiberglass, a thermoplastic material, plastic, rubber, and metal. See [0070+].
Regarding claim 57, Li teaches 57. (New) The method of claim 41, wherein the core includes one or more of an open-cell structure or a lattice structure. See [0081+].
Regarding claim 58, Li teaches 58. (New) The method of claim 41, wherein the core includes at least one of polypropylene, aluminum, Nomex, and Kevlar. See [0072+].
Claims 44, 52-54 are rejected under 35 U.S.C. 103 as being unpatentable over Li (US 20240424366 A1) in view of Fox (US 20170136325 A1) and Severa (US 20250312666 A1).
Regarding claim 44, Severa teaches 44. (New) The method of claim 41, wherein the gap is between 0.1 mm to 100 mm deep measured from an edge to a center of the sandwich structure. See [0207+] which shows the length W which can easily be utilized for the gap length to be between 5mm to 25 mm.
It would have been obvious to one of ordinary skill in the art, at the date of the effective filing, to modify Li with Several as the examiner notes that the gap length is a result effective variable. In Re Aller states that "Where the general conditions of a claim are disclosed in the prior art, it is not inventive to discover the optimum or workable ranges by routine experimentation.” (See MPEP 2144.05 II) As such, it would have been obvious to one skilled in the art, at the time of the invention, to modify Li to obtain optimal ranges by routine experimentation.
Regarding claim 52, Severa teaches 52. (New) The method of claim 41, wherein the frame defines a hollow interior portion. See Fig. 43; (6148) which shows a hollow interior portion in the frame.
It would have been obvious to one of ordinary skill in the art, at the date of the effective filing, to modify Li with Severa to allow the frame section to be filled with another material.
Regarding claim 53, Severa teaches 53. (New) The method of claim 52, further comprising inserting a second filler within at least a portion of the hollow interior portion of the frame. See Fig. 43; (6252) which shows the hollow interior portion filled with another material.
It would have been obvious to one of ordinary skill in the art, at the date of the effective filing, to modify Li with Severa to allow the frame section to be filled with another material.
Regarding claim 54, Li teaches 54. (New) The method of claim 53, wherein one or more of the first filler and the second filler includes at least one of pressurized air, a polymer, a thermoplastic material, a thermoset material, a thermoplastic elastomer, an elastomer, a rubber, a foam, a polymeric foam, and an expandable material.
