In reply to Joe.

Cisco must be aware of StrikeForce's Patent Infringment Litigation against Duo. Why else would Cisco pay $2.3 Billion, when Duo's Market Cap was Half that Value a year ago. Imo, the Settlement, Royalities, Duo will have to pay to StrikeForce Technologies was included the $2.3 Billion Dollar Price Tag, not to mention the Treble (3X) Damages that the courts may impose on Duo.

I think it's travesty, that DUO built it's Huge customer base mainly on infringing upon StrikeForce Technologie's Patented Out of Band Authentication which was first patented by StrikeForce's CTO in 2003.
It's been an uphill battle for little StrikeForce as it continues it's David vs Golith Battle.

Duo is not the only Company StrikeForce has in Court for Patent Infringment as the current case's are about to come to the Righteous Verdict Conclusion.

As a former shareholder of Cisco in the 1990's I admired Cisco's Growth under the honorable CEO John Chambers.
