Apple and Samsung told the U.S. District Court in San Jose they failed to reach agreement during a mediation session on part of their long-standing patent infringement dispute, said a joint court filing by the two companies Friday. The companies are seeking a settlement to avoid moving forward with a planned March 31 trial over a lawsuit in which Apple claims Samsung violated multiple Apple patents in its Galaxy S3 smartphone and other recent devices, including Apple’s Siri voice search technology. Apple CEO Tim Cook and Samsung co-CEO J.K. Shin met for a daylong mediation session earlier this month, but the session and followup phone calls between the two companies on the mediator’s proposed settlement were “unsuccessful,” they said in the court filing. Apple and Samsung said they “remain willing to work through the mediator” to resolve the patent dispute.
