Office Action

§102 §103 §112
DETAILED ACTION 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 . Status of the Claims This Office Action is in response to the Applicants’ filing on 02/18/2026. Claims 1-20 were previously pending, of which claims 1-20 have been amended, no claims have been cancelled, and claims 21-22 have been newly added. Accordingly, claims 1-22 are currently pending and are being examined below. Continued Examination Under 37 CFR 1.114 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and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicants’ submission filed on 02/18/2026 has been entered. Response to Arguments With respect to Applicant's remarks, see pages 10-13, filed 02/18/2026; Applicant’s “Amendment and Remarks” have been fully considered. Applicant’s remarks will be addressed in sequential order as they were presented. With respect to the claim rejections under 35 U.S.C. § 103, applicant’s “Amendment and Remarks” have been fully considered and are not persuasive. Further consideration of the prior art of record determined that the previously applied prior art does appear to disclose the amended claim language. In light of the new scope, it appears Bernini most closely aligns with the newly amended claims. Due to the nature of the applicant’s amendments, the scope of the applicant’s invention has changed. New application of prior art addresses the amended language, as mapped below. Therefore, the amended claims are newly rejected under 35 U.S.C. § 102/103, and have been updated in the office action below. Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. Claims 1 and 11 are rejected under 35 U.S.C. 112(b) as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. The phrase “during a completion of a mowing task” is not well defined in the specification. During is used only in the context of data collected while the mowing task is being performed. The term completion is used in reference to reports and invoicing. The term completing is used in “a number of instances of human intervention while completing the mow pattern” and suggests more of the process of the mowing. The term completed is used in “metrics of a completed mowing task, as well as “a pattern to be completed.” The term could be interpreted to mean during the process of mowing, rather than the transmission of data at the end of the mowing. Claims 2-10 and 12-22 are rejected under 35 U.S.C. 112(b) as being dependent on rejected claims 1 and 11, and for failing to cure the deficiencies listed above. Claim Rejections - 35 USC § 102/103 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)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. (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 1, 3, 5, 8-9, 11, 13, 15, 18-19, and 21-22 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Bernini (EP 3324261 A1), hereinafter Bernini. In the alternate, the claims are rejected under 35 U.S.C. § 103 as being obvious over Bernini in view of Ott et al. (US 2018/0143634 A1), hereinafter Ott. With respect to claims 1 and 11, Bernini discloses a system comprising: one or more processors; and one or more non-transitory computer readable media having instructions stored thereon, which, when executed by the one or more processors, cause the one or more processors to perform operations comprising: (see at least [0045] “The system… also comprises a remote memory unit 200 electrically connected to its own electronic processor and accessible remotely via radio from the radio module of the lawn mower robot 100.”) receiving, for a mowing area, a mowing task comprising a mow pattern; (see at least [0049] “remote memory unit 200 processes a cutting strategy which advantageously comprises at least one path 300 to be followed by the lawn mower robot 100.”) completing the mowing task by autonomously controlling the movement of an autonomous lawn mower based on the mow pattern; (see at least [0055] “the lawn mower robots 100 are powered up and start to cut the grass of the various zones of the area A with their cutting means 102 following a predetermined path 300 on the basis of the cutting strategy decided in the first step;”) receiving data from the autonomous lawn mower during completion of the mowing task, the data comprising sensor data from one or more sensors associated with the autonomous lawn mower, wherein the sensor data is captured in accordance with the mow pattern determined to complete the mowing task; (see at least [0055] “as the lawn mower robots 100 gradually carry out the cutting, they send ambient data (block 1003) towards the remote memory unit 200 which decides whether to modify the cutting strategy” Note: During completion is interpreted to describe the actual progression of the mowing.) determining, using the sensor data, an updated mow pattern for completing the a subsequent mowing task for the mowing area; (see at least [0055] “if the cutting strategy is modified, the new data for controlling the motors of the various lawn mower robots 100 is sent towards the latter” [0031] “the movement strategy or cutting strategy means the prior programming of a movement path of one or more lawn mower robots 100 within the lawn area A, and subsequent activation of the movement means 101 in accordance with the prior programming.”) autonomously controlling the movement of the autonomous lawn mower during a completion of the subsequent mowing task for the mowing area based on the updated mow pattern. (see at least [0031] “the movement strategy or cutting strategy means the prior programming of a movement path of one or more lawn mower robots 100 within the lawn area A, and subsequent activation of the movement means 101 in accordance with the prior programming.”) Although the interpretation given above is considered to be taught by Bernini the limitation of receiving data from the autonomous lawn mower during completion of the mowing task could alternatively be interpreted as mean a during a process performed upon a completion of a task. Ott teaches the determination of having reached an end point and the storage of the path program at a remote operation center for future use, in paragraph [0102]. The combination of Bernini and Ott would have the updated program being transmitted to the memory at the end of the mowing pattern. As both are in the same field of endeavor, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to modify the autonomous lawnmower control of Bernini to include the end point disclosed in Ott, with reasonable expectation of success. The motivation for doing so would have been to provide a determination that the path had been completed and the control could be terminated, see Ott [0102]. With respect to claims 3 and 13, Bernini discloses the one or more processors further perform, based at least in part on the data, generating information indicative of an attribute associated with an environment, (see at least [0011] “inhibiting areas inside the perimeter of the area… progressively stored in accordance with the plurality of ambient data.”) and wherein the attribute comprises one or more of: characteristics of a lawn mowed by the autonomous lawn mower, position of obstacles in the environment, identity of obstacles in the environment, identity of vegetation in the environment, or position of vegetation in the environment. (see at least [0038] “The data processing unit is programmed to receive the ambient data coming from the contact or proximity sensors 103 and from the stereoscopic video camera 110, if installed, and to execute a processing of the data aimed at defining a position in the area A of the obstacles detected by them.” [0035] “obstacles, such as, for example and without limiting the scope of the invention, plants and shrubs.”) With respect to claims 5 and 15, Bernini discloses the one or more processors further perform receiving additional data from at least one additional autonomous lawn mower, and the autonomous lawn mower and the at least one additional autonomous lawn mower operate collectively as a fleet of autonomous lawn mowers. (see at least [0052] “The presence of obstacles, encountered by the robot mower 100… is transmitted as ambient data towards the remote memory unit 200 and processed… in real time, so as to update instantaneously the path 300 that the other lawn mower robots 100 may travel along, precisely according to the presence of the obstacles.”) With respect to claims 8 and 18, Bernini discloses the one or more sensors comprise one or more of a camera, a radar, a lidar, an ultrasonic transducer, or a Global Navigation Satellite System (GNSS) receiver, (see at least [0034] “the contact or proximity sensors 103 are radar sensors or impact sensors” [0039] “a localisation module 105 conveniently using a GPS/GLONASS satellite receiver which is able to allow positioning of the lawn mower robot 100”) and wherein the one or more processors further perform: determining, based at least in part on the sensor data, a location of one or more obstacles in an environment associated with the mow pattern; (see at least [0033] “sensor means which assist the definition of its position, as well as the detection of obstacles and allow a better operation in the strategy of mowing the lawn.” [0038] “defining a position in the area A of the obstacles detected by them.”) and determining, based at least in part on the obstacles, a further updated mow pattern for the at least one lawn mower based on the updated mow pattern; (see at least [0052] “update instantaneously the path 300 that the other lawn mower robots 100 may travel along, precisely according to the presence of the obstacles.”) and transmitting, to the at least one autonomous lawn mower, the further updated mow pattern. (see at least [0022] “updating of the movement strategy according to the plurality of parameters, and a step for transmitting the updated movement strategy towards the plurality of lawn mower robots.”) With respect to claims 9 and 19, Bernini discloses the updated mow pattern comprises a mow pattern that minimizes one or more of an amount of energy or an amount of time for the at least one autonomous lawn mower to complete mowing in accordance with the mow pattern. (see at least [0057] “By controlling and progressively updating the position of two or more automatic lawn mower robots as described above it is possible to optimise the time taken in cutting the grass in the predetermined area A, avoiding an unnecessary waste of time and energy in repassing a second lawn mower robot over a zone of the area A wherein the lawn has already been cut.”) With respect to claims 21 and 22, Bernini discloses the updated mow pattern is associated with at least one of a reduced amount of time to traverse the environment relative to the mow pattern, a minimal amount of time to complete mowing the mow pattern, a less amount of energy relative to the mow pattern, a minimal amount of energy to complete mowing the mow pattern, a fewer number of stripes relative to the mow pattern, a fewer number of obstacles relative to the mow pattern, or a shorter distance travelled relative to the mow pattern. (see at least [0057] “By controlling and progressively updating the position of two or more automatic lawn mower robots as described above it is possible to optimise the time taken in cutting the grass in the predetermined area A, avoiding an unnecessary waste of time and energy in repassing a second lawn mower robot over a zone of the area A wherein the lawn has already been cut.”) 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: 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, 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. Claims 2 and 12 are rejected under 35 U.S.C. 103 as being unpatentable over Bernini as applied to claims 1 and 11 above, and further in view of Ott. With respect to claims 2 and 12, Bernini discloses the mowing of a lawn by an autonomous lawn mower using an updated path and detecting a low charge, but does not explicitly disclose the monitoring of the diagnostic data of the autonomous lawnmower. However, Ott discloses the one or more processors further perform, based at least in part on the data, generating information indicative of a diagnostic of the autonomous lawn mower, and wherein the diagnostic comprises one or more of: a state of charge of a battery of the autonomous lawn mower, a motor temperature of a motor of the autonomous lawn mower, a tire pressure of a wheel associated with the autonomous lawnmower, an attribute of blade maintenance, a total time mowed while mowing the pattern followed by the autonomous lawn mower while traversing an environment, a distance travelled by the autonomous lawn mower since a last maintenance service, a mow pattern tracking error, a number of instances of human intervention while completing the mow pattern, a battery health, software and computing diagnostic information for lawn mower software and hardware, or functionality of the one or more sensors. ([0041] “Controller 202 communicates with a plurality of sensors 230, such as a… battery gauge, and/or fuel gauge. Using sensors 230, controller 202 determines a current status 270 of robot 102.” [0063] “Dashboard 382 also shows a bar graph 416 representing one or more of: available fuel and/or battery level, available treatment material 224, and so on.” [0057-0058]) As both are in the same field of endeavor, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to modify the autonomous lawnmower control of Bernini to include the status monitoring disclosed in Ott, with reasonable expectation of success. The motivation for doing so would have been to resolve situations encountered by the robot that cannot be resolved by the robot, see Ott [0056]. Claims 4 and 14 are rejected under 35 U.S.C. 103 as being unpatentable over Bernini as applied to claims 1 and 11 above, and further in view of Balutis et al. (US 2019/0250604 A1), hereinafter Balutis. With respect to claims 4 and 14, Bernini discloses the mowing of a lawn by an autonomous lawn mower using an updated path, but does not explicitly disclose the remaining path includes a number of stripes. However, Balutis teaches the one or more processors further perform, based at least in part on the data, generating information indicative of a metric associated with the autonomous lawn mower, and wherein the metric comprises one or more of: an amount of area covered during the mowing task, a number of stripes required to cover the mowing area, an average number of times a portion of the mowing area was cut, an average area per time, an amount of time used by the autonomous lawn mower to mow the mow pattern, an amount of energy used by the autonomous lawnmower to mow the mow pattern, or a total area mowed by the autonomous lawnmower. (see at least [0062] “FIG. 4G depicts an example screenshot of the displayed map image 460 with a graphic overlay 468 showing a graphic overlay 466 showing the progress of the robot lawnmower 10 and a projected remaining path of the robot lawnmower 10 as it mows the lawn.”) It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify Bernini to include the above limitations as detailed in Balutis with the motivation being to increase user convenience by allowing the user to easily visualize both the portion of the yard mowed and the path to be followed to complete the mowing as detailed in Balutis [0062]. Claims 6-7, 10, 16-17, and 20 are rejected under 35 U.S.C. 103 as being unpatentable over Bernini as applied to claims 1 and 11 above, and further in view of He et al. (US 2019/0278269 A1), hereinafter He. With respect to claims 6 and 16, Bernini discloses the mowing of a lawn by an autonomous lawn mower using sensor data, but does not explicitly disclose determining additional landscaping services required. However, He teaches one or more processors to perform operations comprising: determining, using the sensor data, additional landscaping service required in an environment, including at least one of: maintenance on trees, maintenance on bushes, trash removal, a tree to be cut, a bush to be trimmed, a portion of the mowing area needing lawn maintenance, a region requiring a change in irrigation levels, or a location of leaves to be removed. (see at least [0016] “In one of embodiments, the working module comprises at least two of a grass cutting module, a liquid spraying module, a fertilizing module, a soil loosening module, a fallen leaves collecting module, a sowing module, a withered grass removing module, and a sweeping module, to respectively perform the corresponding lawn care works.”) As both are in the same field of endeavor, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to modify Bernini to include the above limitations disclosed in He, with reasonable expectation of success. The motivation for doing so would have been to provide a user with a single robot that can complete multiple functions to the user doesn’t need to select different functional machines at different times and to control on and off the different functional machines when performing courtyard maintenance, see He [0005]. With respect to claims 7 and 17, Bernini discloses the data is received at a first time, and wherein the operations further comprise: receiving, at a second time after the first time, additional data from the autonomous lawn mower; (see at least [0052] “The presence of obstacles, encountered by the robot mower 100… is transmitted as ambient data towards the remote memory unit 200 and processed… in real time”) Bernini discloses the mowing of a lawn by an autonomous lawn mower using sensor data but does not explicitly disclose determining additional landscaping services required. However, He teaches confirming, based at least in part on the additional data, whether the additional landscaping service has been taken care of. (see at least Fig. 7, [0280] “The self-moving gardening robot 100 enters the designated location point to perform water spraying and transmits completion information to the application after precise water spraying is done at the preset location.”) As both are in the same field of endeavor, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to modify Ott to include the above limitations disclosed in He, with reasonable expectation of success. The motivation for doing so would have been to provide the user a relevant condition of completion of precise water spraying at a location by the self-moving gardening robot 100, see He [0280]. With respect to claims 10 and 20, Bernini discloses the mowing of a lawn by an autonomous lawn mower using sensor data, but does not explicitly disclose determining additional landscaping services required. However, He teaches the attribute of the environment further comprises: at least one environment requirement of a job site based on the sensor data, (see at least [0198] “The service end 300 collects and counts data of the self-moving gardening robot 100 through the user equipment 200 or/and sends various prompt instructions to the user equipment 200.”) and the operations further comprise notifying a customer of the at least one environment requirement including services to fulfill the at least one environment requirement. (see at least [0270] “prompt the user of the specific low-frequency functional task that needs to be performed on the part of the working area, so that the user performs functional task switch.”) As both are in the same field of endeavor, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to modify Ott to include the above limitations disclosed in He, with reasonable expectation of success. The motivation for doing so would have been to provide the user a relevant condition of completion of precise water spraying at a location by the self-moving gardening robot 100, see He [0280].
