Out sibling site brings word that Nokia is suing Apple in Delware court. Why-for?

ten patents related to GSM, UMTS, and WLAN standards that Nokia states they established after investing more than EUR 40 billion in R&D over the last 20 years. Nokia stated that they have successfully entered into license agreements including these patents with approximately 40 companies, including virtually all the leading mobile device vendors, allowing the industry to benefit from Nokia’s innovation.

Seems other companies have coughed up the cash to use them, but Apple's waiting for a court to force their hand. With $35 billion in the bank, they can obviously afford to give a fortune away to the lawyers, but why go to the effort? Do they really think a court will somehow dismiss the patents as invalid?

Pass the popcorn, get ready for some patent pugilism, and let us know what you think!
