It seems that Nokia kicked over the hornet's nest back in October when they sued Apple for infringing on wireless patents that they claim others have been legitimately paying for while Apple has been refusing to pay for. Not surprisingly, Apple then sued Nokia for infringing on their user interface patents, which Nokia followed up with their own interface lawsuit. We then recently saw what seems to be a rather stupid request from Nokia to have Apple iPhone, iPod, and Mac computers banned from being imported. Of course, the latest filing from Apple (thanks Engadget) asking the US government to ban Nokia phone imports is the expected retaliation we have come to expect from these two.
I am not a lawyer and won't even start to try to figure out who, if either, is right in this scuffle. All we know for sure is that 2010 is shaping up to be a nice busy year for Nokia and Apple lawyers. I highly doubt either company will be successful in having the other one banned and it all seems to really be a bunch of legal posturing.
