Office Action

§112
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 . DETAILED ACTION Applicant’s election of Group I on 12/19/2025, without traverse, is hereby acknowledged. Groups II and III are withdrawn from further consideration by the examiner, 37 CFR § 1.142(b), as being for non-elected designs. Note Regarding Applicant’s IDS Three foreign patent references on Lines 2, 5 and 6 have been lined through on applicant’s IDS submitted 12/11/2025 because they are not visually relevant to the claimed design in this application. Instead, these references pertain to a lifting mechanism, motor drive drawer, and a pillow. While these patents may be relevant to the mechanical arm in particular, it is not part of that which is being claimed. Objection to the Specification The amended broken line statement following the reproduction descriptions is objected to because the phrase [in the drawings] appears both before and after the deleted portion. Therefore, the broken line statement should be amended to read: -- The broken lines show in the drawings depict environmental subject matter and form no part of the claimed design. – It would also be acceptable to describe the broken lines as depicting portions of the cleaning robot that form no part of the claimed design. Objections to the Drawings 1) It is suggested that the reproduction labels be enlarged to be at least .32 cm. (1/8 inch) in height, since the printed patent is further reduced in size to two-thirds in reproduction and the reproduction labels are currently very small. Numbers, letters, and reference characters must measure at least .32 cm. (1/8 inch) in height. 37 CFR § 1.84(p)(3). 2) Reproductions 1.1, 1.7, and all figures in Embodiment 5 are objected to because the broken lines are gray and blurry, which would not permit satisfactory reproduction. Hague Rule 9(2)(a) states: Reproductions shall be of a quality permitting all the details of the industrial design to be clearly distinguished and permitting publication. Also, while the extendable arm visible in these reproductions is understood to be disclaimed in its entirety, random portions appear to be drawn in solid lines. Care should be taken to amend the disclaimed portions for consistency in scope and legibility. See annotated drawing below in which the solid lines are pointed out in the otherwise disclaimed extendable arm in Reproduction 5.8 as an example: PNG media_image1.png 272 606 media_image1.png Greyscale Corrected drawing sheets 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.” 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. When preparing new or replacement drawings, be careful to avoid introducing new matter. New matter is prohibited by 35 USC § 132 and 37 CFR § 1.121(f). Non-Final Rejection under 35 USC § 112(a) and (b) The claim is rejected under 35 USC § 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 the inventor or joint inventor regards as the invention. The claim is indefinite and non-enabling for the following reasons: 1) Some features of the claimed design cannot be understood in a three-dimensional sense from the views shown. In particular, there are interior features visible only in Reproduction 1.1 and 5.1 from a front view that do not show any depth. Therefore, their exact appearance cannot be determined. See shaded portion in annotated drawing below in Reproduction 1.1 as an example: PNG media_image2.png 356 576 media_image2.png Greyscale 2) There are interior features visible in Reproductions 1.4, 1.5, 1.8, 5.4, 5.5, and 5.8 whose appearance is also not understood in a three-dimensional sense even in the perspective views. See annotated drawings below in which the confusing areas have been shaded gray, as an example: PNG media_image3.png 440 670 media_image3.png Greyscale As the questionable instances are numerous, not every confusing line is indicated on the annotated drawings. The annotations are intended to show examples of the problems; the onus is on the applicant to set forth a clear and consistent disclosure. Due to the confusion caused by the lack of sufficient views from which to understand the three-dimensional appearance of certain interior features, the claimed design is in fact subject to multiple interpretations, and one of ordinary skill in the art would not be able to reproduce the design without the use of conjecture. This renders the claim indefinite and non-enabled. To overcome this rejection, it is suggested that applicant submit new drawings of the claimed design that show the design clearly and consistently. If certain non-enabled portions of the design cannot be fully enabled without the introduction of new matter, applicant may remove from the claim the areas or portions of the design that are considered indefinite and non-enabling by converting them to broken lines. Conclusion Accordingly, the claim stands rejected under 35 USC § 112(a) and (b) as set forth above. Discussion of the Merits of the Case: 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’, may be used for this purpose: https://www.uspto.gov/patent/forms/forms-patent-applications-filed-or-after-september-16-2012 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. If a pro se applicant or registered practitioner located outside of the United States wishes to communicate by telephone, it is suggested that such person email the examiner at kimberly.barnes@uspto.gov to arrange a time and date for the telephone interview. Please include proposed days and times for the proposed call. When proposing a day/time for the interview, please take into account the examiner's work schedule indicated in the last paragraph of this communication. The email should also be used to determine who will initiate the telephone call. Email Communications 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.
