If you own patents then you should always be leary of potential patent infringements, regardless of the current quarterly numbers.
It just so happens ptsc led the way and EDIG apparently saw an opening on how to deal with it.
I don`t see it as anything more than that. The market is gaining respect for small companies claiming their rights.
With flash continuing to increase its storage capacity and companies like DELL leaving the microdrive for flash products, not to mention Apple`s successful flash product line among others, I can`t think of a better time for EDIG to leverage TPL and go hunting.
