The determination of obviousness requires not only finding all elements of the claimed invention in the prior art but also establishing a clear motivation to combine those elements with a reasonable expectation of success.

Understanding the Claims of US11003191

The independent claims of US11003191 generally describe a self-propelled pool cleaner with:

A vehicle body and means for moving it within a pool.
A filter for debris.
At least one camera on or in the body to capture images of the submerged surface.
A controller (either on-board or remote) in electronic communication with the camera, configured to generate control signals based on the captured images to direct the cleaner's movement.

Prior Art References

The patent itself cites numerous prior art documents in its "Patent Citations" section. For this analysis, we will consider the general state of the art as reflected in the provided patent text and the search results.

Key themes in the prior art as revealed by the provided context include:

Automated robotic pool cleaners: These are well-established, with various propulsion mechanisms (wheels, tracks, jets), debris collection systems, and internal control systems.
Cameras for monitoring pools and vehicles: Cameras were used for home/pool security systems and could detect people or intruders. The patent also explicitly states that prior art pool cleaning systems could utilize pre-existing cameras from security systems or dedicated cameras.
Remote control and monitoring of pool systems: Systems existed for controlling pool cleaner chemicals from a keypad of a PC or other interactive controller. Remote communication with automatic swimming pool cleaners was also known.
Image processing for control: The general concept of using camera imagery for control of vehicles, particularly land vehicles, was known, including extracting relative motion information.

Combinations of Prior Art References and Motivation for Combination

A PHOSITA, at the time of the invention (priority date of July 10, 2012), would have possessed knowledge of these existing technologies.

Combination 1: Automated Pool Cleaner with On-Board Camera for Navigation and Cleaning Assessment

References:
- AU2019236716B9 (Bellamy et al.): Discloses a pool cleaner with a housing, a debris container, a drive system with a motor to drive wheels for movement, and a control system. It also mentions a remote control unit (e.g., mobile device application) to control movement and other functions.
- US20110049023A1 (Hui Wing-Kin): Describes a pool cleaning vehicle having improved logic. While the specific details aren't exhaustively provided, the title suggests advanced control.
- US2004019295A1 (Aqua Products Inc.): Discloses a "Pool cleaner with on-board water analysis, data recording and transmission device." This shows a precedent for on-board data collection and transmission.
- General knowledge of cameras and image processing: It was known to use cameras for security and monitoring, and general image processing for vehicle control was a developing field.
Motivation to Combine:
- Problem: The background of US11003191 explicitly states that "controlling and monitoring such automated robotic pool cleaners to insure that all portions of the pool surfaces are satisfactorily cleaned remains a challenge." Existing robotic pool cleaners, while automated, did not necessarily guarantee comprehensive cleaning or provide feedback on areas missed or poorly cleaned.
- Solution: A PHOSITA would have been motivated to integrate an on-board camera with an automated pool cleaner's control system to address this challenge.
  - Enhanced Navigation and Coverage: By incorporating a camera (as generally known for security/monitoring, and potentially for land vehicle navigation), the cleaner's control system (as found in Bellamy et al.) could process images to better understand its position and the areas it has covered. This would allow for more systematic cleaning patterns, reducing missed spots and improving efficiency, directly addressing the problem of ensuring satisfactory cleaning.
  - Real-time Cleanliness Assessment: The inclusion of an on-board camera, coupled with the "on-board water analysis, data recording and transmission device" concept from Aqua Products Inc., would motivate a PHOSITA to analyze imagery for "cleanliness characteristics" (e.g., presence of debris, discoloration). This provides feedback for the cleaner to re-clean unsatisfactory areas, as disclosed in US11003191. The concept of identifying missed or unsatisfactorily cleaned areas and directing the cleaner back to them is a logical extension of existing automated cleaning systems.
  - Technological Feasibility: The integration of cameras and image processing into robotic systems was a known technological trend. The development of smaller, more robust cameras suitable for submerged environments, along with advancements in processing power, would have made this combination technically feasible. The patent itself mentions the use of existing security cameras or dedicated cameras with appropriate lenses for submerged environments, indicating that the camera technology itself was not novel for this purpose.

Combination 2: Remote Monitoring and Control of a Camera-Equipped Pool Cleaner with Graphical Display of Cleaning Progress

References:
- Combination 1 (Automated Pool Cleaner with On-Board Camera and Controller)
- EP1540612A1 (Zodiac Pool Systems, Inc.): Discusses a "Pool cleaner with on-board water analysis, data recording and transmission device" and explicitly mentions display devices, including stationary devices in the user's home and the ability to maintain the system from a keypad of a PC or other interactive controller keypad. It also notes that remote communication with automatic swimming pool cleaners was known.
- AU2019236716B9 (Bellamy et al.): Mentions a remote control unit (e.g., by means of an application on a mobile device) to control various aspects of the pool cleaner.
- General knowledge of portable electronic devices (PEDs): Smartphones, tablets, etc., were becoming ubiquitous and commonly used for remote control and monitoring of various home devices.
Motivation to Combine:
- Problem: While automated cleaners existed, users still faced the challenge of "controlling and monitoring such automated robotic pool cleaners to insure that all portions of the pool surfaces are satisfactorily cleaned." The prior art suggests that pool owners had to be vigilant and check systems periodically, which was inconvenient.
- Solution: A PHOSITA would have been motivated to combine the camera-equipped, intelligently controlled pool cleaner (from Combination 1) with remote monitoring and control capabilities using a graphical display on a portable electronic device.
  - Improved User Experience and Assurance: Providing a graphical depiction of cleaned and uncleaned areas on a display (as in US11003191) directly addresses the need for better monitoring and assurance of cleaning effectiveness. The concept of using a remote display and control, already present in EP1540612A1 for pool systems and in Bellamy et al. for pool cleaner control via mobile devices, would naturally extend to displaying the camera-derived cleanliness map.
  - Convenience and Efficiency: Remote monitoring via a PED allows users to oversee the cleaning process without being physically present at the pool, addressing the inconvenience mentioned in EP1540612A1. The ability to "input commands causing controller 42 to generate control signals... to steer vehicle 30 back to such identified portions" (as taught by US11003191) or adjust settings remotely (as also taught by US11003191) enhances efficiency by allowing immediate intervention without manual retrieval of the cleaner.
  - Design Need/Market Pressure: There would be a clear market demand for more user-friendly and efficient pool cleaning solutions. Leveraging ubiquitous portable electronic devices for remote control and visual feedback represents a predictable next step in improving automated pool maintenance systems.

Conclusion on Obviousness

Based on the above analysis, a PHOSITA would have found the claims of US11003191 obvious in light of combinations of the identified prior art references. The motivation stems from:

Addressing known problems: The explicit challenge of ensuring satisfactory and comprehensive cleaning by robotic pool cleaners was a recognized problem in the art.
Leveraging existing technologies and trends: The components (automated pool cleaners, cameras, controllers, remote communication, portable displays, image processing for control) were individually known. The trend of integrating sensors and intelligent control into autonomous vehicles, as well as providing remote monitoring and control via mobile devices, would have motivated a PHOSITA to apply these concepts to pool cleaners.
Predictable solutions: The combination of these known elements to achieve predictable results (improved navigation, cleaning assessment, and user interaction) would have been within the grasp of a PHOSITA.

Therefore, the combination of a self-propelled pool cleaner with an on-board camera, a controller to interpret imagery for cleanliness and direct movement, and a remote display on a portable electronic device to show cleaning progress and allow for user input, would likely be considered obvious under 35 U.S.C. § 103.
