Apple and Samung lawyers have been directed by the federal judge to meet and confer in person on Monday and file joint and disputed final jury instructions by Monday in patent infringement.

"The Court is disappointed by the parties' respective reports regarding their meet and confer efforts on final jury instructions," U.S. District Judge Lucy Koh said in her order today, according to Foss Patents. "Lead trial counsel shall meet and confer in person today and file joint and disputed final jury instructions by Monday, August 13, 2012 at 8 a.m."

A report by CNET said that the order comes after the two companies reportedly accused each other of impeding the jury instruction process. Foss reports that an Apple filing late Friday claimed that "although [it] has tried diligently to advance the process, Samsung has stymied those efforts." Samsung reportedly responded by saying it had "agreed to more than twenty revised instructions proposed by Apple and is continuing to review Apple's remaining disputed instructions for any common ground," while Apple had "agreed to only two complete instructions drafted solely by Samsung."

Their disagreement over what the jury should be told when the companies rest their cases is just the latest courtroom row in the high-stakes trial, it said.
