Bad blood can be costly. 

Apple Inc.'s (AAPL) - Get Apple Inc. (AAPL) Report patent lawsuit against Samsung is entering its final phase, with the Cupertino-based company seeking $1 billion in damages from its South Korean counterpart. 

Apple claims that Samsung infringed on three of its patents, and is seeking damages equivalent to the profit it claims Samsung made off of its design patents. 

Samsung, meanwhile, is hoping to convince the jury to cap the damages it has to pay at a much lower level, arguing that the penalty should only apply to the specific components of its devices that infringed on Apple's patents. 

Samsung has the U.S. Supreme Court on its side following a 2016 ruling governing how damages are calculated in patent infringement cases.

"The only way Apple can come up with $1 billion in damages is by saying the article of manufacture applies to the whole phone," Samsung attorney John Quinn told the jury, according to ZDNet. "None of the patents is the whole phone."

Apple is a holding of the Action Alerts PLUS charitable trust managed by Jim Cramer.
