Patentability shall not be negated by the manner in which the invention was made. 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. Claim(s) 20 and 22-39 is/are rejected under 35 U.S.C. 103 as being unpatentable over Huster in view of Romo et al. (U.S. Pub. No. 2021/0077651) (hereinafter “Romo”). Regarding claim 22, Huster teaches the limitations of the base claim(s). But Huster does not explicitly teach wherein the position data comprises x-direction travel telemetry, y-direction travel telemetry, and z-direction travel telemetry of the patient lift. However, Romo teaches wherein the position data comprises x-direction travel telemetry, y-direction travel telemetry, and z-direction travel telemetry of the patient lift. (Para. 71, 127 - - position data includes three-dimensional coordinates data, where Huster has taught travel position of patient lift outlined above) Huster and Romo are analogous art because they are from the same field of endeavor and contain overlapping structural and/or functional similarities. They both contain systems used to manage patients in a medical/hospital setting. Therefore, before the effective filing date of the claimed invention (AIA ), it would have been obvious to a person of ordinary skill in the art to modify the above limitation(s) as taught by Huster, by incorporating the above limitation(s) as taught by Romo. One of ordinary skill in the art would have been motivated to do this modification in order to manage precisely a target area/space, as suggested by Romo (Para. 71). Regarding claim 28, Huster further teaches wherein adjusting the one or more settings comprises controlling…at or proximate to a location of the patient lift within the medical room. (Para. 107 - - airflow, pressure, i.e. settings, is adjusted related to patient mobile support system, i.e. lift, at or proximate to the lift) But Huster does not explicitly teach controlling a disinfecting unit to disinfect air However, Romo teaches controlling a disinfecting unit to disinfect air (Para. 71 - - disinfection devices are controlled) Huster and Romo are analogous art because they are from the same field of endeavor and contain overlapping structural and/or functional similarities. They both contain systems used to manage patients in a medical/hospital setting. Therefore, before the effective filing date of the claimed invention (AIA ), it would have been obvious to a person of ordinary skill in the art to modify the above limitation(s) as taught by Huster, by incorporating the above limitation(s) as taught by Romo. One of ordinary skill in the art would have been motivated to do this modification in order to disinfect a target area/space, as suggested by Romo (Para. 71). Regarding claim 29, Romo further teaches wherein controlling the disinfecting unit comprises controlling emission of ultraviolet light, UVC light, Far-UVC light, near ultraviolet light, 405 nm wavelength light, or vaporized hydrogen peroxide. (Para. 71 - - ultraviolet disinfection devices are controlled) One of ordinary skill in the art would have been motivated to do this modification in order to disinfect a target area/space, as suggested by Romo (Para. 71). Regarding claim 31, Huster teaches the limitations of the base claim(s). But Huster does not explicitly teach determining a safety condition based at least in part on speed data included in the position data. However, Romo teaches determining a safety condition based at least in part on speed data included in the position data. (Para. 193 - - speed or velocity data is used in disinfection; Para. 173 - - disinfection is done in safe manner, where safety is related to speed/velocity above) Huster and Romo are analogous art because they are from the same field of endeavor and contain overlapping structural and/or functional similarities. They both contain systems used to manage patients in a medical/hospital setting. Therefore, before the effective filing date of the claimed invention (AIA ), it would have been obvious to a person of ordinary skill in the art to modify the above limitation(s) as taught by Huster, by incorporating the above limitation(s) as taught by Romo. One of ordinary skill in the art would have been motivated to do this modification in order to manage precisely a target area/space, as suggested by Romo (Para. 71). Regarding claim 33, Huster teaches a method of controlling movement of a patient lift within a medical room, (Para. 79 - - system controls patient mobile support system, i.e. lift) the method comprising: receiving, by a controller, position data corresponding to a position of the patient lift within the medical room, (Para. 66 - - position data related to patient mobile support system, i.e. lift, is used) the position data being generated by one or more sensors associated with at least one of the patient lift, a gantry coupled to the patient lift, or one or more rails along which the gantry is movable; (Para. 66 - - frame, i.e. lift position, and side rail position sensors are used) determining, by the controller and based at least in part on the position data, a current position of the patient lift…within the medical room; (Para. 66 - - position data related to patient mobile support system, i.e. lift, is used) receiving, by the controller, environmental data corresponding to an environmental condition at or proximate to the current position of the patient lift; (Para. 71, 73 - - sensors gather feedback data including environmental information in a medical room) determining, by the controller, whether the environmental condition satisfies a threshold condition; (Para. 107-108 - - temperature data is used as sensor feedback data, and determination is made if temperature reach unacceptable levels, i.e. exceed threshold) and generating, by the controller, one or more control signals to adjust operation of at least one of the patient lift or an environmental control component within the medical room (Para. 107 - - airflow, pressure, i.e. settings, is adjusted related to patient mobile support system, i.e. lift; Fig. 1 - - environmental controller is used to adjust operation) based at least in part on the determination of whether the environmental condition satisfies the threshold condition. (Para. 82, 107 - - threshold is used in sensor feedback system to determine if the threshold is exceeded, and adjustment is based on the determination, including temperature, i.e. environmental condition) But Huster does not explicitly teach position…in at least two coordinate directions However, Romo teaches position…in at least two coordinate directions (Para. 71, 127 - - position data includes three-dimensional coordinates data) Huster and Romo are analogous art because they are from the same field of endeavor and contain overlapping structural and/or functional similarities. They both contain systems used to manage patients in a medical/hospital setting. Therefore, before the effective filing date of the claimed invention (AIA ), it would have been obvious to a person of ordinary skill in the art to modify the above limitation(s) as taught by Huster, by incorporating the above limitation(s) as taught by Romo. One of ordinary skill in the art would have been motivated to do this modification in order to manage precisely a target area/space, as suggested by Romo (Para. 71). Regarding claim 34, Romo further teaches wherein determining the current position comprises determining a position of the patient lift along an x-axis, a y-axis, and a z-axis within the medical room. (Para. 71, 127 - - position data includes three-dimensional coordinates data, where Huster has taught travel position of patient lift) One of ordinary skill in the art would have been motivated to do this modification in order to manage precisely a target area/space, as suggested by Romo (Para. 71). Regarding claim 35, Huster further teaches wherein receiving the environmental data comprises receiving environmental data from one or more environmental sensors carried by the patient lift as the patient lift moves through the medical room. (Para. 71, 73 - - sensors gather feedback data including environmental information in a medical room, where patient lift moves in medical room) Regarding claim 36, Huster further teaches wherein the one or more control signals adjust an environmental condition at a location identified by coordinates of the patient lift within the medical room. (Para. 107 - - airflow, pressure, i.e. settings, is adjusted related to patient mobile support system, i.e. lift, located at the surface of the support, i.e. at an identified location) Regarding claim 37, Huster further teaches wherein generating the one or more control signals comprises generating a control signal…to adjust airflow at or proximate to the current position of the patient lift. (Para. 107 - - airflow, pressure, i.e. settings, is adjusted related to patient mobile support system, i.e. lift, located at the surface of the support, i.e. at or proximate to patient lift) Romo further teaches to adjust an angle or size of an opening of one or more vents (Para. 78 - - arm can be adjusted at a variety of angles, where Huster teaches airflow control system, i.e. via vents) One of ordinary skill in the art would have been motivated to do this modification in order to manage precisely a target area/space, as suggested by Romo (Para. 71). Regarding claim 38, Romo further teaches wherein generating the one or more control signals comprises generating a control signal to control a disinfecting unit based at least in part on at least one of particulate count data or microbial count data included in the environmental data. (Para. 71 - - disinfection devices are controlled; Para. 90 - - pathogen, i.e. microbial count, are eradicated at various levels, i.e. counts) One of ordinary skill in the art would have been motivated to do this modification in order to disinfect a target area/space, as suggested by Romo (Para. 71). Regarding claim 39, Huster further teaches maintaining a current operating setting when the environmental condition does not satisfy the threshold condition. (Para. 107-108 - - temperature data, i.e. environmental condition, is used as sensor feedback data, and determination is made if temperature reach unacceptable levels, i.e. does not satisfy threshold condition, in which case, cooling is performed) It is noted that any citations to specific, pages, columns, lines, or figures in the prior art references and any interpretation of the reference should not be considered to be limiting in any way.
