We received a letter today, first thinking it was bogus and then confirming it. At the moment it has been passed off to our lawyers.
In the letter it states that users of WiFi are in violation of patents held by this company. The letter is fairly vague for technical specs and only lists patent numbers that are in violation. Looking out on the web it appears that other people have gotten letters of this sort demanding payments of $2,300 - $5,000 for a one time license fee for people to continue to use WiFi technologies.
Has anyone else heard of this before? With about 100 AP's in service we don't have that large of a deployment and we are surprised they would target us in such an obvious attempt to squeeze money out of people. It appears that this affects not only Cisco equipment but several other major manufactures as well.
It appears that Cisco and Motorola have joined together in a suit to declare that it's products do not infringe on the patents.
