Obviousness

Obviousness Analysis under 35 U.S.C. § 103 for US Patent 10904487

The independent claims of US Patent 10904487 (Claims 1, 8, and 15) focus on a whiteboard device, computer-readable media, and a computer-implemented method, respectively, for integrating videoconferencing with interactive electronic whiteboard sessions. The core inventive steps common to these claims are:

1. Displaying an interactive whiteboard session window with a content area.
2. Overlaying a selection menu on the interactive whiteboard session window to receive an instruction for starting a videoconference session.
3. After receiving the instruction, overlaying a videoconference window on the interactive whiteboard session window.

The following analysis considers combinations of prior art references from the provided "Prior art" section and the motivation a person having ordinary skill in the art (PHOSITA) would have had to combine them, rendering the claimed invention obvious.

Combination: US20150009278A1 (Avaya) + General Knowledge of a PHOSITA in GUI Design and Operating System Window Management

Primary Reference: US20150009278A1 (Avaya) – "System and method for whiteboard collaboration"

Teachings of Avaya:
Avaya describes a system and method for "whiteboard collaboration in a communication environment" and explicitly mentions a "conference call". This reference teaches enabling multiple users to collaborate on a shared whiteboard during a communication session, facilitating real-time interaction with the whiteboard content and synchronizing changes across participants' devices. This directly addresses the display of an interactive whiteboard session window within a collaborative communication context, which inherently involves a videoconference.

Missing Elements from Independent Claims of US10904487:
While Avaya teaches the integration of whiteboard collaboration with a communication session, it does not explicitly detail the specific graphical user interface (GUI) interactions claimed by US10904487:

• Overlaying a selection menu directly on the interactive whiteboard session window for the purpose of starting a videoconference session.
• Subsequently, overlaying a videoconference window directly on the interactive whiteboard session window after the instruction is received.
  Avaya implies that the whiteboard operates within an existing communication session, rather than providing the mechanism for initiating that session with the claimed window overlay features.

Motivation for a PHOSITA to Combine/Modify:
A PHOSITA in the field of interactive whiteboard systems and videoconferencing, at the time of the invention (priority date May 9, 2015), would have been motivated to enhance the user experience and streamline the workflow for collaborative sessions.

1. Problem Identification: Existing systems, or those suggested by Avaya, might require users to navigate away from the interactive whiteboard application or use a separate interface to initiate a video conference. This creates a disjointed user experience and interrupts the flow of collaboration.
2. Known Solutions (Common Sense & PHOSITA Knowledge): A PHOSITA would be well aware of standard GUI design principles aimed at improving usability and efficiency. Overlying menus and windows are common techniques used in operating systems and applications to provide contextual controls and to integrate secondary functionalities without fully obscuring the primary application or forcing a complete context switch.
   • The detailed description of US10904487 itself describes employing standard operating system functions, such as FindWindow() to identify windows and setting the WS_EX_TOPMOST bit in the GWL_EXSTYLE field, to control window layering [cite: The full patent text, section "III. ELECTRONIC WHITEBOARD AND VIDEOCONFERENCING SESSION INTEGRATION A. Startup", "B. Establishing a Videoconferencing Session"]. These are well-established programming interfaces for window management.
3. Predictable Results: By integrating a "Start Videoconferencing Session" option into a menu that is overlaid on the interactive whiteboard (e.g., a "collaboration menu icon" as depicted in FIG. 3A and 3B of US10904487 [cite: The full patent text, FIG. 3A, FIG. 3B]), and then displaying the video conference window as an overlay on the whiteboard, users could seamlessly initiate and participate in video calls while maintaining the context of their whiteboard work. This provides a more intuitive and efficient user interface for a combined collaborative and communication environment. The ability to switch between these windows (e.g., using options like "Show Videoconferencing Session" or "Show Whiteboard" [cite: The full patent text, section "III. ELECTRONIC WHITEBOARD AND VIDEOCONFERENCING SESSION INTEGRATION C. Sharing a Whiteboard"]) further supports this goal of seamless interaction.

Therefore, the combination of Avaya's teaching of interactive whiteboard collaboration in a communication environment with the ordinary skill of a PHOSITA to apply well-known GUI and operating system window management techniques (such as overlaid menus and windows) to improve user workflow would render the independent claims of US10904487 obvious. The specific method of "overlaying" these elements would be a logical and predictable design choice for achieving a user-friendly integrated system.
