VisiMap technology is protected by two granted U.S. patents and a family of pending applications, spanning foundational concepts through current state-of-art implementation.
Both trace to the same December 1, 2010 priority date. The '925 patent is a continuation of the foundational '041 patent.

The foundational patents establish parallel multi-fiber identification using unique port signatures across two dimensions: color (wavelength differentiation) and rhythmic pattern (distinct flash sequences). A 4-color by 7-pattern matrix enables 28 unique signatures from a single device — replacing one-at-a-time testing with simultaneous, parallel identification.
A growing family of pending applications extends the foundational patents into full non-contact, encoded, bidirectional fiber mapping.

The generational leap from visual-only identification to full non-contact, encoded, bidirectional fiber mapping: DMX512 protocol with Morse code encoding, camera-based non-contact detection, encrypted symbol substitution, bidirectional infrared communication, and integrated OTDR instrumentation. The continuation-in-part adds protection for optical-switch architectures that reduce the number of light sources required. A divisional application covering two-way communications and optical switching for OTDR use is also on file.
Together, these patents cover the full workflow from basic visual fiber identification through automated, instrument-grade fiber plant mapping and qualification.
The '041 and '925 patents establish the foundational concept: parallel multi-fiber identification using unique port signatures via a color and pattern matrix.
The '873 application and its continuation-in-part extend into non-contact, encoded, bidirectional territory with camera detection, encrypted encoding, optical switching, and integrated test instrumentation.
Portfolio spans from the 2010 priority date through 2025 publications — representing over 15 years of continuous research and development in a single technical domain.
