Claim Rejections - 35 USC § 103 The text of those sections of Title 35, U.S. Code not included in this action can be found in a prior Office action Claims 2-5 are rejected under 35 U.S.C. 103 as being unpatentable over Ellwood in view of Stedman (1,010,199). PNG media_image9.png 299 333 media_image9.png Greyscale Ellwood meets all of the limitations of claim 2, as described above, however in the alternative and in order to expedite the prosecution, except for providing a second coupling coupled to a second gaiter coupling. Stedman teaches a glove having a cuff coupling 2 at the proximal end adapted to couple with a second coupling provided on the cuff 3. It would have been obvious to one of ordinary skill in the art, before the effective date of the invention, to modify the second end of the body of Ellwood with a second coupling to couple with a coupling on a cuff as taught by Stedman forming a gauntlet to extend the protection over the forearm. Regarding claim 3, PA (prior art, Ellwood modified by Stedman) meets the limitations, i.e., the gaiter of claim 2, further comprising cuff coupling 4 adapted to removably mate with the second gaiter coupling 2, Figs. 1 and 2 Stedman. Regarding claim 4, PA meets the limitations, i.e., the gaiter of claim 3, further comprising an arm cuff portion 3, wherein the cuff coupling is integrated into an arm cuff portion Fig. 2 Stedman. Regarding claim 5, PA meets the limitations, i.e., the gaiter of claim 3, wherein the cuff coupling 3 is integrated into a piece of personal protective equipment (PPE) or clothing protective glove and gauntlet modified gaiter. Claims 8-11 are rejected under 35 U.S.C. 103 as being unpatentable over PA in view of Fournier (2005/0223470). PNG media_image10.png 184 198 media_image10.png Greyscale PA (prior art, either Ellwood or Gustafsson) meets all of the limitations of claim 8, as described above, except for the main body to include first, second, and third material layers. Fournier teaches a protective sleeve to be worn on the user’s forearms to be utilized with an electrically insulated glove protecting user’s hand and wrist. The protective sleeve is comprised of an inner comfort layer made of denim or other comfortable material laminated to an outer electrically insulated layer. It would have been obvious to one of ordinary skill in the art, before the effective date of the invention, to augment the invention of PA with the two-part covering as taught by Fournier to provide comfort and protect the user from electric shock when the glove and gauntlet is utilized on applications with danger of electric shock. Regarding claim 9, PA (prior art, either Ellwood or Gustafsson modified by Fournier) meets the limitations, i.e., the gaiter of claim 8, wherein the first material layer protective cover Ellwood or comfort layer, Fournier forms an internal side of the main body, the third material layer outer covering as modified by Fournier forms an external side of the main body. Regarding claim 10, PA meets the limitations, i.e., the gaiter of claim 8, wherein the second material layer is non-conductive. Note that providing the comfort layer on the inner side, to provide comfort for the user and apply the electric insulation on the external side with the heat non-conductive covering Ellwood in the middle, to protect against electric shock first external layer, Fournier, heat second layer Ellwood and comfort inner comfort layer, Fournier, would have been obvious to one of ordinary skill in the art, requiring routine experimentations with predictable results and since it has been held that rearranging parts of an invention involves only routine skill in the art. In re Japikes, 86 USPQ 70. Regarding claim 11, PA meets the limitations, i.e., the gaiter of claim 8, wherein the third material layer external layer is non-conductive electrically and abrasion resistant rubber with some degree of abrasion resistance. Response to Arguments Applicant's arguments filed July 31, 2026 have been fully considered but they are not persuasive. Applicant argues that “Examienr incorrectly asserts that the shank 4 of Ellwood corresponds to a handle of a tool, cylindrical recess 2 of Ellwood corresponds to the claimed first opening and also to the claimed first gaiter coupling, and the handle 3 of Ellwood corresponds to the claimed tool coupling. However, the cylindrical recess 2 of Ellwood is not a first opening that is adapted to receive insertion of a handle of a tool through the first opening, as claimed. Rather, the cylindrical recess 2 of Ellwood merely receives the handle 3 of Ellwood when the handle 3 of Elwood is inserted into the hand shield 1 from an opposite side of the hand shield 1 of Ellwood. Applicant further argues that the shank 4 of a cooking utensil of Ellwood is not a handle of a tool that a user interacts with. Rather, a user would interact with the handle 3 of Ellwood, not the shank 4 of Ellwood. Further yet, the handle 3 of Ellwood does not include a tool coupling opening adapted to receive insertion of the handle therethrough, or frictionally couple to a tool and removably mate with a first gaiter coupling to removably couple the tool to the main body when the handle is inserted through the first opening, as claimed”. Examienr, respectfully disagrees. As noted above the elements recited in the claims are met by the art applied. [AltContent: arrow][AltContent: textbox (GAITER OPENING DEFINED BY THE HANDLE 11)]Claim 1 requires a main body comprising first and second ends each defining a first opening and a second opening for receiving an insertion of a tool handle and for insertion of a user’s hand, respectively. Elwood meets these requirements, i.e., shield 10 defines a first opening receiving the shield’s handle 11 @ recess 2. The handle 11, which is tightly received in the cylindrical recess 2 of the shield, itself defines the gaiter coupling and includes a gaiter coupling opening in which the shank/handle 12 is received. The gaiter coupling opening and the first opening coincide. Similar to the instant application, in which the first opening 124 and the gaiter coupling opening 108 coincide and is defined at the same location, e.g., as shown in Fig. 2 of the instant application. Claim 1 further requires a tool coupling, which is met by pin 13 of Elwood. While claims terminologies are interpreted in light of the specification, limitations from specification are not read into the claims. Accordingly, opening defined by the shield 10 defines the first opening and the opening of the shield’s handle 11 defines the gaiter coupling opening. PNG media_image6.png 481 511 media_image6.png Greyscale Similarly, Gustafsson meets all of the limitations, i.e., a main body having opposing first LF and second RT ends and first 6 and second openings 10 respectively disposed proximal to the first and second ends Fig. 2, wherein the first opening 6 is adapted to receive insertion of the handle Fig. 2 and the second end @10 is adapted to receive insertion of a hand of a user to allow the user to interact with the handle manipulate the handle, Fig. 2 within the main body 10; a first gaiter coupling channel at opening 6 [0033] coupled to the first end and including a gaiter coupling opening e.g., @ 40 adapted to receive insertion of the handle annotated Fig. 4a; and a tool coupling tightening device 7 adapted to couple to the tool between the handle and the working end Fig. 2 and removably mate [0033] with the first gaiter coupling channel at opening 6 to removably couple the tool to the main body when the handle of tools 1 or 3 is inserted into the gaiter coupling opening @40 and the first opening 6 annotated Fig. 4a.
