This probably isn't the end for Nvidia's lawsuit, but these sort of processes last for a long time and they don't usually cause any significant blow in a company's profits. However, the ITC has the power to ban the sale of certain devices, and that could potentially harm a company like Samsung.
This isn't the only lawsuit that Samsung has going on. It's also involved in another patent war with Apple, and the last time we heard the two companies agreed on a court-supervised meditation which is going to take a while to process. Battles like these are slowly starting to become the norm as many companies have a bone to pick with each other.
