Protequus® Expands IP Portfolio for NIGHTWATCH®

Protequus® announces the issuance of a supplemental utility patent (patent no. 9,894,885) by the Unites States Patent and Trademark Office (USPTO) for MOBILE ANIMAL SURVEILLANCE AND DISTRESS MONITORING. This patent enhances the already robust portfolio of intellectual property (IP) behind NIGHTWATCH®, the World’s first smart halter™. NIGHTWATCH® is a revolutionary IoT-enabled device that acts as an early warning system for horses whereby caretakers are alerted via text, phone call, and email at the first signs of a problem, such as colic and other forms of equine distress.

The road to receiving a utility patent is a long one that often takes many years, if successful. To begin, an inventor must conceive of a solution to a problem. This solution must be unique, novel, and non-obvious in nature. In the case of NIGHTWATCH®, the problem is equine colic, which is the leading natural case of death in horses and second only to old age. If detected early, colic can be easily managed in the vast majority of horses without the need for costly or invasive surgery. Unfortunately, horses spend much of their day unsupervised, so early identification and intervention of colic is often delayed and results in poor survival and qualify-of-life outcomes.

To identify early signs of equine distress, NIGHTWATCH® analyzes real-time data on a horse’s vital signs and behaviors. Whereas a 9-axis IMU (inertial measurement unit) gathers data on their activity, motion, and posture, UWB-IR (ultra-wideband impulse radar) monitors their heart rate and respiratory rate, the two most important vital signs that correlate with pain and acute distress in horses. UWB-IR is a safe radio technology that uses very low energy over a large portion of the radio spectrum. After years of refinement, engineers at Protequus® and NRGXP have harnessed this non-invasive technology to measure the physical displacement (ie, constriction and dilation) of the microvasculature around a horse’s poll (ie, area behind their ears) for heart rate, while also assessing physical changes in the soft tissue of their upper respiratory region for respiratory rate. “The issuance of this patent comes at a great time for us as we are presently preparing for the US and Canadian launch of NIGHTWATCH® on April 26, 2018, just prior to the start of the Kentucky 3-Day Event in Lexington, KY,” says Jeffrey R. Schab, Founder & CEO of Protequus®.

NIGHTWATCH® ( is the World's first smart halter (optional safety collar) designed to alert caretakers via text, phone call, and email at the early signs of danger/distress in their horse, such as colic, being cast, and foaling. This patented IoT-enabled device monitors real-time data on a horse’s vital signs and behaviors, works across 3G/cellular and Wi-Fi networks, offers GPS tracking, and leverages AI/machine learning to adapt to each horse over time for maximum precision and benefit. Access to real-time insight and historical information, including a horse's EDI® (Equine Distress Index®) score, is available on-demand 24/7 from any smartphone, tablet, or computer.

About Protequus®
Protequus® ( is a biomedical engineering and data science firm in Austin, TX dedicated to equine health & safety. Founded in 2013 after the sudden loss of one of his horses to colic, Jeffrey R. Schab—an accomplished equestrian and biomedical engineer—assembled a team of passionate science & technology professionals to find a solution to combat the devastating impact of colic, which claims the lives of >60,000 horses each year in the US and results in more than $700 million in annual losses. Today, that solution is known as NIGHTWATCH® and will be available to horses domiciled in the US and Canada starting on April 26, 2018.
