Office Action

§103 §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 This communication is a non-Final office action on merit. Claims 2 and 10 were canceled. Clams 1, 3-9, after amendment, are presently pending and have been considered below. Request for Continued Examination A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 2/4/2026 has been entered. Information Disclosure Statement The information disclosure statement (IDS) submitted on 11/21/2022, 8/20/2025, and 2/25/2026 is in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement has been considered by the examiner. Priority Acknowledgment is made of applicant’s claim for foreign priority under 35 U.S.C. 119 (a)-(d). The certified copy has been filed in parent Application No. DE10 2020 113 810.5, filed on 5/22/2020. Invocation of 35 USC § 112(f) The following is a quotation of 35 U.S.C. 112(f): (f) Element in Claim for a Combination. – An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof. The following is a quotation of pre-AIA 35 U.S.C. 112, sixth paragraph: An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof. The claims in this application are given their broadest reasonable interpretation using the plain meaning of the claim language in light of the specification as it would be understood by one of ordinary skill in the art. The broadest reasonable interpretation of a claim element (also commonly referred to as a claim limitation) is limited by the description in the specification when 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is invoked. As explained in MPEP § 2181, subsection I, claim limitations that meet the following three-prong test will be interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph: (A) the claim limitation uses the term “means” or “step” or a term used as a substitute for “means” that is a generic placeholder (also called a nonce term or a non-structural term having no specific structural meaning) for performing the claimed function; (B) the term “means” or “step” or the generic placeholder is modified by functional language, typically, but not always linked by the transition word “for” (e.g., “means for”) or another linking word or phrase, such as “configured to” or “so that”; and (C) the term “means” or “step” or the generic placeholder is not modified by sufficient structure, material, or acts for performing the claimed function. Use of the word “means” (or “step”) in a claim with functional language creates a rebuttable presumption that the claim limitation is to be treated in accordance with 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. The presumption that the claim limitation is interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is rebutted when the claim limitation recites sufficient structure, material, or acts to entirely perform the recited function. Absence of the word “means” (or “step”) in a claim creates a rebuttable presumption that the claim limitation is not to be treated in accordance with 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. The presumption that the claim limitation is not interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is rebutted when the claim limitation recites function without reciting sufficient structure, material or acts to entirely perform the recited function. Claim limitations in this application that use the word “means” (or “step”) are being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, except as otherwise indicated in an Office action. Conversely, claim limitations in this application that do not use the word “means” (or “step”) are not being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, except as otherwise indicated in an Office action. This application includes one or more claim limitations that do not use the word “means,” but are nonetheless being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, because the claim limitation(s) uses a generic placeholder that is coupled with functional language without reciting sufficient structure to perform the recited function and the generic placeholder is not preceded by a structural modifier. Such claim limitation(s) is/are: a central unit suitable for receiving in claim 1. Because this/these claim limitation(s) is/are being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, it/they is/are being interpreted to cover the corresponding structure described in the specification as performing the claimed function, and equivalents thereof. If applicant does not intend to have this/these limitation(s) interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, applicant may: (1) amend the claim limitation(s) to avoid it/them being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph (e.g., by reciting sufficient structure to perform the claimed function); or (2) present a sufficient showing that the claim limitation(s) recite(s) sufficient structure to perform the claimed function so as to avoid it/them being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. Claim Rejections - 35 USC § 112 The following is a quotation of the first paragraph of 35 U.S.C. 112(a): (a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention. The following is a quotation of the first paragraph of pre-AIA 35 U.S.C. 112: The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention. Claims 1, 3-9 are rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention. Claim 1 is amended as “at least one mobile notification unit, configured as a visual marker that demarcates a boundary of a restricted area. …”. Examiner fails to find an expressive and/or sufficient description of above limitation. Claims 3-9 depend from claim 1. They are rejected with the same reason. Claim Rejections - 35 USC § 103 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: 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 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. This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention. Claims 1, 3-9 are rejected under 35 U.S.C. 103 as being unpatentable over US 2013/0172004 A1, Bahl (hereinafter Bahl) in view of US 2023/0381959 A1, Thomaz et al. (hereinafter Thomaz). As to claim 1, Bahl discloses a warning system comprising: at least one mobile notification unit, configured as a visual marker that demarcates a boundary of a restricted area, wherein the notification unit has at least one motion sensor which detects movements of objects in the environment of the notification unit (Figs 18-20, 24; pars 0075, 0129-0131, 0133-0136, a mobile device or cellular phone with a passive motion detector to detect an individual in a room and sending a signal to another device), and wherein the notification unit has at least one signal device which is suitable for outputting an optical or acoustic signal if the motion sensor has detected a movement of an object in the environment of the notification unit (Figs 3-5; pars 0049, 0053-0054, 0060, 0062, 0064, 0129-0130, an audio signal being sent upon motion sensor detecting a movement of an individual); and a central unit comprising a receiver configured for receiving a signal sent via radio from the at least one notification unit and to then output a notification to a user of the central unit (pars 0061, 0077, 0082, 0098, 0129-0130, 0166-0167, a mobile device or cellular phone receiving alert/alarm message over the radio), wherein the notification unit is able to detect whether the object is crossing or has crossed the boundary of the restricted area (Figs 19, 21-26, various detection modules (infrared, passive/active motion detectors, etc.) detecting an object’s or a person’s motion within ranges of detection or a specified proximity of the mobile device; pars 0007, 0009-0012, 0127, 0130, 139, a person entering a room of the house (e.g. crossing the room boundary)), and that the signal is changeable when the object is crossing or has crossed the boundary of the restricted area (Figs 2, 4, 22, 0031; pars 0049, 0054, 0120, 0126- 0130, 0138-0139, 0162, the mobile device detects motions (motion signal changes) and generating an audible alarm (e.g. signal change) to alert the user a person or an intruder entering a living room or bedroom). Bahi does not expressly disclose the at least one mobile notification unit, configured as a visual marker that demarcates a boundary of a restricted area. Thomaz, in the same or similar field of endeavor, further teaches at least one mobile notification unit, configured as a visual marker that demarcates a boundary of a restricted area (Figs 7-8, 17; pars 0117-0118, 0137, 0146, 0183, 0297). Therefore, consider Bahi and Thomaz’s teachings as a whole, it would have been obvious to one of skill in the art before the filing date of invention to incorporate Thomaz’s teachings in Bahi’s warning system to provide automatic warning system with a marker to indicate the boundary of environment with restricted access. 2. (Canceled) As to claim 3, Bahl as modified discloses the warning system according to claim 1, wherein the central unit is couplable to a communication unit disposed within a hearing protection of the user so that the notifications can be output via the hearing protection to the user (Bahi: pars 0095-0086, 0157-0158, using a vibration signal for hearing impaired person). As to claim 4, Bahl as modified discloses the warning system according to claim 1, wherein the central unit is a cellular phone or is couplable to a cellular phone (Bahi: Figs 8, 22; pars 0074-0075, 0092, 0095-0099, 0129-0130). As to claim 5, Bahl as modified discloses the warning system according to claim 4, wherein the cellular phone is equipped with an application indicating on a display of the cellular phone that a movement of an object has been detected in the environment of the notification unit (Bahi: Figs 19, 21-25, presenter module to present movement in a proximity; pars 0007, 0009-0012, 0072, 0075, 0110-0118, 0122, 0158, 0175, presenter module may generates sound, vibration, and/or display to indicate motion being detected). As to claim 6, Bahl as modified discloses the warning system according to claim 1, wherein several notification units are provided and that the type of the notifications output at the central unit depends on which notification unit has sent a signal (Bahi: pars 0117, 0122, 0129, multiple mobile devices/cellular phones may be serving as notification unites). As to claim 7, Bahl as modified discloses the warning system according to claim 1, wherein the notification unit comprises an identification module which is suitable for detecting at least one property of the object (Bahi: pars 0053, 0065, 0086-0088, speech or voice recognition capability to identify the voice of the person). As to claim 8, Bahl as modified discloses the warning system according to claim 1, wherein the notification unit comprises a camera (Bahi: pars 0096, 0117, 0122, a camera). As to claim 9, Bahl as modified discloses the warning system according to claim 1, wherein the notification unit comprises a GPS receiver (Bahi: Fig 18; pars 0096, 0062, 0098-0099, 0110, a GPS).
