March 10, 2008 - GraphOn Corp., a publishing software developer, said Monday it is suing five big Web businesses for patent infringement: CareerBuilder, Classified Ventures, Yahoo, eHarmony.com, and IAC/InterActive Corp. GraphOn settled a lawsuit with AutoTrader in January 2008 and has also sued Juniper Networks.
Classified Ventures is a joint venture of five major newspaper publishers. The suit, filed in the US District Court for the Eastern District of Texas, alleges that the companies infringed on four GraphOn patents related to "maintaining an automated and network- accessible database."
That is a lot of patent infringement going on from other big corporations--allegedly.
I'll be interested in seeing how Yahoo does and eHarmony.com just because I am most familiar with those two.
Hopefully more studying will go on regarding patents and patent infringement by companies.
