I have covered other WLAN patent suits here and here. While I’m no patent lawyer, what this says to me is that the WLAN market is starting to level-off and firms are looking for “other” ways to make some money without producing products. A business tacit fresh from the 1980′s.
I also noticed that this suit between a European firms (Ericsson) and Asian firms (Acer, Netgear and D-Link) was brought in U.S. District Court for the Eastern District of Texas. This seems to be a favorite place for firms to sue each other, I wonder if anyone has ever investigated why this court is so popular for alleged patent-troll cases.
One of the things that we instituted a while ago, in our RFP’s and contract’s is a clause that requires the VAR and the manufacturer to hold the end-user harmless in regards to patent suits the VAR or manufacturer may get entangled in.
