It’s in case studies, and refers to an ages old relationship with MaxD, that has been referenced in MaxD’s 10k/10qs every year for 4 years. In 2016 MaxD said they would have a product demo by Q3 2017. In 2017, most recently, they said they would have a demo by Q2 2018. They have also announced licensing deals with cell phone manufacturers but those went nowhere.
But you seem hooked on the sound encryption patent, patent pending since 2014, and granted last spring. Can you tell us more about a product they have developed in the last 4 years? I am unaware of one, none having ever been revealed by MaxD in any press release, marketing materials, or filings - including the most recent one.
