PayPal hit by new patent suit
First USA Bank has filed suit against PayPal, alleging that the online payment company is infringing on its patents. The lawsuit was filed Friday in U.S. District Court in Delaware. It involves two patents that cover "cardless payment" systems, which allow consumers to pay for transactions using a telephone number and a security code.

The article is pretty scarce on details, has there been any follow-ups? From what I've seen so far in similar cases (such as the hotlinking case), I'm not sure the patent will hold... this seems to be a software feature and I am not sure how east it would be to patent, especially if there is variation in the code, which I am sure there is.
