Office Action

§112
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . DETAILED ACTION General Information The merits of this case have been carefully reviewed in light of Applicant’s election, received on July 14, 2025. The election of Group 3 (Figs. 3.1-3.9), without traverse, has been noted. Groups 1, 2, and 4 have been withdrawn from consideration by the examiner, 37 CFR 1.142(b), as being drawn to a non-elected design. In accordance with the applicant’s election, the applicant should file a full set of replacement reproductions and figure descriptions showing only Figs. 3.1-3.9. Specification Objection The specification is objected to for the following reason: Descriptions of the figures are not required to be written in any particular format, however they should describe the views of the drawing clearly and accurately. (MPEP 1503.01 §II) For accuracy, when multiple perspective views are shown, explaining exactly which direction the perspective views are showing, is helpful to distinguish them from one-another. Therefore, the figure descriptions should be amended to read, for example: --3.1 Top, front, left side perspective view 3.2 Top, front, right side perspective view 3.3 Top, back, right side perspective view 3.4 Top, back, left side perspective view-- Since there are two inventors, for clarity, the formal claim statement should be prefaced with the phrase “We claim”. Further, since the applicant has elected a caliper body for disc brake, the formal claim statement should be amended to remove the reference to the non-elected designs. For example: --We Claim: The ornamental design for a Caliper body for disc brake as shown and described.-- Claim Rejection - 35 USC § 112 The claim is refused under 35 U.S.C. 112(a) and (b), as the claimed invention is not described in such full, clear, concise and exact terms as to enable any person skilled in the art to make and use the same, and fails to particularly point out and distinctly claim the subject matter which applicant regards as the invention. The claimed invention is indefinite and non-enabled because the overall shape and configuration of the design cannot be understood with the drawings provided. The appearance of circular features and depressions on the surface of the caliper body is unclear. These features appear throughout the reproductions on the interior and exterior of the caliper body. Where these features are simple circles, it is not clear if they are flat surface, depressions, or holes. If they are depressions or holes, their interior surfaces could be located at a variety of depths, angles, or curvatures within the body of the caliper body. Where the features are depressions, their exact depth cannot be determined from the reproductions, since they could extend a variety of distances into the body of the caliper body. Because of these ambiguities, the exact appearance of circular features and depressions on the surface of the caliper body cannot be determined without resorting to conjecture. The claim is indefinite and non-enabling. PNG media_image1.png 1302 986 media_image1.png Greyscale As a potential means of overcoming this portion of the rejection, the applicant may consider reducing the indefinite and non-enabling circular features and depressions to unclaimed broken lines. Should the applicant amend the drawings and/or specification, the amendment must meet the written description requirement of 35 U.S.C. 112(a). It must be apparent that the applicant was in possession of the amended design at the time of original filing. When preparing new or replacement drawings, be careful to avoid introducing new matter prohibited by 35 U.S.C. 132(a) and 37 CFR 1.121(f). Applicant may file amendments in reply to the Office action to avoid abandonment of the application. If corrected drawings are submitted in response to the Office action, they must be in compliance with 37 CFR 1.121(d). Any amended replacement drawing sheet should include all of the claimed figures, even if only one figure is being amended. Replacement sheets cancel all previous disclosures. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as “Replacement Sheet” pursuant to 37 CFR 1.121(d). If the examiner does not accept the changes, the applicant will be notified and informed of any required corrective action in the next Office action. The corrected drawings must meet the written description requirement of 35 U.S.C. 112(a) and not contain new matter (35 U.S.C. 132; 37 CFR 1.121). Conclusion The claimed design is refused under 35 USC 112(a) and (b), with specification objections as discussed. Discussion of the Merits of the Application All discussions between the applicant and the examiner regarding the merits of a pending application will be considered an interview and are to be made of record. See MPEP 713. The examiner will not discuss the merits of the application with applicant’s representative if the representative is not registered to practice before the USPTO. Appointment as applicant’s representative before the International Bureau pursuant to Rule 3 of the Common Regulations under the Hague Agreement does NOT entitle such representative to represent the applicant before the USPTO. Furthermore, an applicant that is a juristic entity must be represented by a patent attorney or agent registered to practice before the USPTO. Additional information regarding interviews is set forth below. Telephonic or in person interviews A telephonic or in person interview may only be conducted with an attorney or agent registered to practice before the USPTO (“registered practitioner”) or with a pro se applicant (an applicant who is the inventor and who is not represented by a registered practitioner). The registered practitioner may either be of record or not of record. To become “of record”, a power of attorney (POA) in accordance with 37 CFR 1.32 must be filed in the application. Form PTO/AIA /80 “Power of Attorney to Prosecute Applications Before the USPTO”, available at https://www.uspto.gov/patent/forms/forms-patent-applications-filed-or-after-september-16-2012, may be used for this purpose. See MPEP 402.02(a) for further information. Interviews may also be conducted with a registered practitioner not of record provided the registered practitioner can show authorization to conduct an interview by completing, signing and filing an “Applicant Initiated Interview Request Form” (PTOL-413A) (available at the USPTO web page indicated above). See MPEP 405. For acceptable ways to submit forms to the USPTO, see “When Responding to Official USPTO Correspondence” below. Email Communication The merits of the application will not be discussed via email (or other electronic medium) unless appropriate authorization for internet communication is filed in the application. Form PTO/SB/439 “Authorization for Internet Communications in a Patent Application or Request to Withdraw Authorization for Internet Communications” may be used to provide such authorization and is available at the USPTO web page indicated above. The authorization may not be sent by email to the USPTO. For acceptable ways to submit the authorization form to the USPTO, see “When Responding to Official USPTO Correspondence” below. See MPEP 502.03 II for further information. Responding to Official USPTO Correspondence The USPTO transacts business in writing. All replies must be signed in accordance with 37 CFR 1.33(b). Pursuant to 37 CFR 1.33(b)(3), a reply submitted on behalf of a juristic applicant must be signed by an attorney or agent registered to practice before the USPTO.
