Throughout the Samsung vs. Apple patent trial, Judge Lucy Koh has been a stern and sardonic overseer that has more often than not resembled a fight between children than an actual lawsuit. Now Koh is speaking up again, telling Samsung and Apple that, once again, they are wasting everyone’s time throwing a million and one allegations at one another, and that they need to “focus and streamline” their cases against one another.

Bloomberg reports:

U.S. District Judge Lucy H. Koh in San Jose, California, today told lawyers from both companies that they must “focus and streamline” their cases to 25 patent claims, or elements of the patents at issue, and 25 accused products.

Koh made the request from the bench today in the latest of two related patent cases. The lawsuit was filed last year and covers technology in newer smartphones made by both companies, including Samsung’s Galaxy S III and Apple’s iPhone 5.

“We’ll keep narrowing and narrowing,” Koh said. “You’ve already been litigating this thing for a year; you must know something about what’s your best case.”

No wonder she’s frustrated: having already gone through one trial between Samsung and Apple, currently awaiting appeal, another is scheduled for 2014. In preparation for this trial, Samsung and Apple are essentially throwing every patent in their arsenals at one another to see what sticks: Samsung has already claimed that “all generations” of the iPhone and iPad infringe their patents, while Apple has recently asked that the Galaxy Note line of smartphones and tablets be listed to their complaint.
