Invention starts with a useful question.
Selected inventions in optical sensing and algorithmic personalization. Three issued U.S. patents naming Justin Saul as co-inventor.
My work as an inventor spans optical sensing, algorithmic personalization, and digital media. I am a named co-inventor on three issued U.S. patents. This is a selection of the ideas behind that work and the practical questions they address.
Optical sensing
Spectrometry Systems and Methods
US12629061B2 · Issued May 19, 2026 · Co-inventor · NNOXX
How can a noninvasive optical system account for the tissue it is measuring? This work describes using light measurements and computational processing to estimate tissue-layer characteristics and other physical properties. It connects sensor design with the interpretation of biological measurements.
Algorithmic personalization
Fashion Matching Algorithm Solution
US8103551B2 · Issued January 24, 2012 · Co-inventor · Style du Jour
How can software recommend clothing combinations based on the relationships between items? This work describes matching fashion items using attributes and a style matrix, including items held in a digital wardrobe. It grew out of an effort to make personalized styling useful in a software product.
Fashion Matching Algorithm Solution — related patent
US8249941B2 · Issued August 21, 2012 · Co-inventor · Style du Jour
A second issued patent in the same personalization family. Together, these records document work on algorithmic matching that began well before the current generative-AI cycle.
From invention to implementation
An invention becomes useful through the product and organization built around it. My work connects technical ideas with architecture, product decisions, and the practical requirements of delivery.
