This patent portfolio covers foundational technologies for real-time collaboration, shared presentations, and interactive annotation systems that enable teams to work concurrently across distributed computing environments. The patents protect methods for layered annotations, role- and team-based collaboration controls, synchronized shared displays, and dynamic presentation assembly over evolving underlying content. With early priority dates dating back to 2011 and unencumbered ownership, the portfolio represents core infrastructure IP for modern collaboration platforms. These technologies are directly applicable to enterprise productivity software, remote work tools, shared whiteboards, design and document collaboration systems, and interactive media platforms, making the portfolio highly relevant for licensing or acquisition by collaboration software providers and cloud productivity ecosystems.
