Apple Inc. (NASDAQ:AAPL) and Samsung will meet at the US Supreme Court on Tuesday as they continue with their patent battle that started in 2012.

Apple filed the lawsuit against Samsung in 2012 arguing that Samsung had copied a patented iPhone design. The case between the two firms will be heard by eight Supreme Court justices. It is also a unique legal battle because the last time that a US court handled a patent dispute was more than a century ago.

The Apple-Samsung legal battle is considered very sensitive due to the impact that it could have to the industry as well as the electronics that consumers will purchase. Both firms have presented their arguments with Samsung claiming that a win for Apple would put a leash on innovation. Apple, on the other hand, claims that if Samsung wins the argument, then it will open a door for manufacturers to take advantage of patents and weaken patent protection. The funny part about the patent legal battle is that the devices affected by the patent are no longer on the market.

“One of the interesting things about this whole odyssey is it’s a great demonstration of how slowly the law moves relative to technology,” stated Professor Mark A. Lemley of Stanford Law School.

Professor Michael Risch of the Villanova University claims that the case will have a significant impact in how the legal system calculates damages for design patents. Samsung was forced to pay $548 million in 2015 and it plans to challenge that $399 million of the awarded sum was wrongly awarded to Apple. Samsung claims that the design infringement only covered a small part of the handsets.

“If the court reverses the way it’s been done in the past, then we might see fewer design patent cases because they won’t be as lucrative,” claims Professor Risch.

Apple stock closed the latest trading session at $114.06, up by $0.17 or 0.15% compared to the price at the previous close.
