A North Carolina judge has invalidated Ubist’s patent claim on a video game, Rocksmith. The game teaches people how to play the guitar.
This whole situation started when Ubist accused a competing Finnish developer infringing on their Rocksmith patent. The Finnish developer’s Yousician program focuses on teaching guitar, piano, bass, , or singing.
Ubist alleges that Yousician mentions their product can be used with a “Rocksmith cable,” which proves the company was aware the game.
Sounded like a valid claim, though U.S. District Judge Louise Flanagan granted the Finnish developer’s motion to dismiss the lawsuit. First filed on August 18th, the judge found Ubist’s patent includes in-eligible subject matter according to U.S. Supreme Court decision Alice v. CLS Bank.
Ubist’s patent for Rocksmith describes a computer program that listens to a user’s performance and accesses how it could be better. The program changes the difficulty the performance based on how well the player did.
The judge argued that while the claims describe how the game can teach a user to play an instrument, the patent filing claims are too broad.
“In short, the claims at issue and specification describe at length what this computer game can do in order to teach a user how to play an instrument, activities which have been historically employed by music teachers, but the claims and specification do not delve into how.”
She described the activities showing students how to play, listening to them play, and creating exercises as “the building blocks teaching an instrument.”
Rocksmith has sold more than 4 million copies since the game was released in 2011. Players use a cord to connect their actual instrument to an Xbox or PlayStation console.
Yousician was released in 2014 and has received over 100 million downloads. Yousician runs on mobile devices and receives audio input through the microphone, or connected device. Neither party responded to quests for comment before press time.
