Apple is taking a company called Sector Labs to court over the word 'pod.'
The row is over a new projector called Video Pod, launched last year, which the iPod maker claims infringes on its music player name.
Apple has filed an 873-page briefing paper to the court laying out its claim to exclusive use of the name, reports the BBC.
Sector Labs have until early October to respond, with the US patents office deciding if Apple has a case.
"What I'm hoping to do with this case is to really reach a lot broader an audience and make it so entrepreneurs and small businesses can use the English language as they see fit in branding their products," Ana Christian, Sector Labs' lawyer, told Wired.com.
"My team started working on the Video Pod in 2000, and it took us years to go from prototype to funded," added Sector Labs Daniel Kokin. "At that time, Apple didn't even enter our minds as a competitor."
Apple has previously taken action against a number of companies and websites using the word pod, including MyPodder, TightPod, PodShow, Podium and iPodLounge.
