Valencia designed a patent strategy to protect both the basic technology and the use of the system for certain applications or conditions. eCoin® is a neurostimulation device that is about the size of a coin, has electrodes (an anode and cathode) integrated into the housing, utilizes a tiny watch battery with certain impedance characteristics, and applies current at a low duty cycle. The patents protect the basic technology and the use of the technology to stimulate nerve X to address chronic condition Y. The chronic conditions for protection are hypertension, heart failure, coronary artery disease, angina, myocardial ischemia, Parkinson’s disease, essential tremor, obesity, dyslipidemia, depression, schizophrenia, post traumatic stress disorder, anxiety, erectile dysfunction, overactive bladder, and osteoarthritis of the knee. For its inventions, Valencia holds thirty issued U.S. patents and over a dozen pending applications under review by the United States Patent and Trademark Office. eCoin® is an investigational device only and is not approved for sale in any country.
