Just reading the story I can tell this isn't the usual patent-infringement stuff.
1. it seems to be for hardware, not software. And these folks manufacture stuff.
2. It's not filed in the Eastern District of Texas, which is the preferred locale for patent trolling (and some non-trolls as well, to be fair)
3. It is filed in Western District of Pennsylvania which is, golly gosh, where they do business
Let's wait and see how this one goes.
