If there's one thing tech companies know how to do better than anyone else, it's sue one another.
The disagreement reportedly began with Samsung's belief that Microsoft breached the companies' "business collaboration agreement" when Microsoft bought Nokia's phone division in September of 2013.
As a result Samsung delayed payments of over $1 billion (about £621m, AU$1.14b) of patent royalties to Microsoft in protest, and now Microsoft says Samsung owes it interest on those late payments.
Agree to disagree
Samsung did eventually resume its royalty payments, but without the interest Microsoft says it's owed.
The royalties Samsung pays Microsoft are due to Microsoft's ownership of technology that Android has been found to be partially based on.
Samsung is not the only company that pays royalties to Microsoft for this reason, but apparently HTC and others didn't skip their payments when Microsoft purchased Nokia's mobile business.
However Motorola is one company that has also refused to pay royalties to Microsoft, and the two have been locked in litigation for years.
Hopefully Samsung doesn't suffer the same fate, especially considering how it fared against Apple.
