Looking for ENDV to benefit from BIEL's success, I own both.
Sofpulse and ActiPatch are similar products. Both operate at 27.12 MHz, same electronics module/antenna design. In fact ActiPatch used Sofpulse as one of its Predicate Devices in their successful 2/2017 FDA 510k which Cleared them for OTC sales for Foot and Knee pain.
The main difference between the two, Sofpulse has two of the CR2032 3v batteries wired in series giving it a 6v power supply. It operates in 15 minute therapy sessions.
ActiPatch operating with one CR2032 battery can be used 24/7 due to the lower power output.
In April 2018 the UK NHS approved ActiPatch as a Covered Medical Device for Pain Relief. This created a lot of attention. There is a US National Retailer Deal due to start soon. There is a Partnership Deal with Dr. Scholl's that should be announced by the end of July. Two days ago MundiPharma announced they had purchased the distribution rights for Australia and New Zealand. The BIEL Sales VP stated that Mundi will add 7 more countries.
With so many similarities between the two products, and the pressure to find solutions to the US Opioid Epidemic Endonovo has to be getting inquiries from parties interested in Sofpulse.
