A U.S. judge denied Apple’s bid to add Samsung’s flagship Galaxy S4 smartphone to a list of products it claims infringe on its patents on Thursday. The decision is part of an ongoing patent trial between the two companies covering recent generations of mobile devices including the Galaxy S III and the iPhone 5.

The decision appears motivated by a desire to keep the trial from dragging on for too long, and in a statement obtained by Bloomberg, U.S. Magistrate Judge Paul S. Grewal noted that adding another device to the proceedings would only be a “tax on the court’s resources.” It looks like this judge, and perhaps the entire American legal system, may be fed up with Apple and Samsung’s ongoing patent spat.

“Each time these parties appear in the courtroom, they consume considerable amounts of the court’s time and energy, which takes time way from other parties who also require and are entitled to the court’s attention,” Grewal said.

One of Apple’s lawyers responded that this decision will actually waste more time since the company will need to file another separate lawsuit over the Galaxy S4, but the judge was apparently unswayed.
