Amazon & Booksurge filed for the lawsuit against them to be dismissed last August. It is understood that the judge in this case will listen to full legal arguments from both parties and make his decision then on whether the case should be set with a formal date and proceed.
The case was taken by Booklocker.com last year following moves by Amazon to cajole some POD publishers into using their own print-on-demand company, Booksurge, for books sold through Amazon.com in the United States. For a period of time last year some POD publishers had their 'first party' buy buttons removed by Amazon from their online site. The strategy of Amazon was seen as an attempt to monopolize the POD book market.
