More evidence that the US PTO needs a severe beating:

Internet phone company Net2Phone has filed a patent infringement lawsuit against rival Skype Technologies and its parent company, eBay.

...

Net2Phone alleges that Skype, a wholly owned subsidiary of eBay, violated its "point-to-point Internet Protocol" patent. The patent calls for the exchange of IP addresses between processing units in order to establish a direct communications link between the devices via the Internet.

A patent on point to point IP? You mean, a patent on some of basic plumbing of the internet, or do they think that the form of the packets they send between hosts are somehow innovative? As to p2p, it's not as if that hasn't been done before, either.
