I'm an investor that is learning as a go along.  I am hoping this stock is my golden ticket.  After the Markman hearing, I had a pretty positive vibe about the outcome and ptsc's future.  I knew the longer the ruling takes to come out the more doubt and worries. 

One question that still concerns me is why the insiders are not buying at these low prices?  Or are they?  Is that kind of information available?  I have seen a lot of option exercises but no buys. 

Also, the term retailers (groups buying) what does it refer to?

These may be obvious to most of you.  I would surely appreciate the help.  Thank you:)
