USPTO Issues Two Patents for a Daily Screening Solution for COVID-19 and Other Infections

The U.S. Patent and Trademark Office (USPTO) issued two patents on January 18, 2022, (patents #US11,224,345B1 and US11,224,346B1), to Ideal Innovations, Inc. (I-3), each called Personal Warning Temperature (PWT) system. PWT uses daily monitoring to compute a person's unique range of normal body temperature and flag abnormalities that indicate infections such as COVID-19. PWT is more accurate than the U.S. Government fever standard of 100.4°F (38°C). 

The PWT system uses a website to help users monitor their own temperature measurements, typically taken at home.  With each new entry, the website determines whether the temperature is above normal. A small, abnormal rise in temperature can warn of COVID-19 up to 24 hours before other symptoms appear, and before conventional testing would confirm the infection. 

"PWT gives people the earliest possible warning that they might be infected with COVID-19 or any other illness for that matter," stated Bob Kocher, CEO of I-3. "Temperature shows when the body is fighting an infection. The U.S. Government standard 'fever temperature' of 100.4°F, based on data from 150 years ago, is too high for today's population. Most people can have anomalous temperatures as low as 99°F. Quite simply, PWT is a game-changer in the long-term fight against COVID-19."

Modern medicine defines a fever as a temperature elevation above normal, but each person's normal temperature range depends on many factors. Elevated temperature can predict the onset of COVID-19 infection if defined in this new, more accurate way. PWT simply helps individuals determine their own personal fever threshold. 

U.S. regulations imply that persons with a temperature less than 100.4°F cannot transmit disease. Organizations use this flawed threshold for entry point screening or quarantine/testing policies. Studies show that 100.4°F is a faulty standard and that transmission can occur at lower temperatures. 

"PWT is a long-term approach that can be deployed immediately and cheaply," said Kocher. "As a screening tool, PWT will reduce the need for costly PCR and antigen tests. The repeal of 100.4°F as the one-size-fits-all fever standard temperature will save lives and hasten the end of the COVID-19 pandemic. PWT is ready to be deployed to hundreds of millions of people."

I-3 is an inventions company working primarily with the Department of Defense. Mr. Kocher is a West Point graduate who served 21 years in the military with six years at the Defense Advanced Research Projects Agency (DARPA), where he gained a reputation as a rapid solution innovator. Other I-3 efforts include secure access systems, early identification of a person's natural ability through neuroscience, and novel implementations for biometrics.
