If Groupon is indeed...infringing on PYN's patent then I would think it would be in our best interest ( obviously ) and Poynt's to challenge them.
They received that ruling a month ago.....if they were serious and showed the market they were serious about defending their patent, I think others would take notice ...others like Google, Groupon, Apple , RIM.
It does nothing but encourage future infringement if PYN just sits back and does nothing.....only breeds more competition and the risk of dilution in their market .....
My guess is that they have concerns but maybe are focusing instead on increasing their user base...promoting the company....and maybe tackling patent issues once the company has a bit more $$$ kicking around....lawyers aren't cheap ..LOL
