Samsung said on Thursday it has not considered acquiring Research In Motion (RIM) or licensing the BlackBerry phone maker's new mobile operating system.
Shares of RIM had risen more than 5 percent early on Wednesday after an influential analyst said it may license the upcoming BlackBerry 10 operating system to Samsung.
A lack of support from potential partners could mean more trouble for RIM, which is seeking various options to turn around its embattled business.
Samsung is the biggest seller of phones that run on Google Inc's Android system, but it also makes phones using Microsoft's Windows as well as its proprietary software called bada.
RIM plans to use its new operating system, known as BB10, in a next-generation line of BlackBerrys expected to launch early next year.
