First reported by Reuters, BlackBerry has asked for "preliminary expressions of interests" from tech companies such as Google, Samsung, LG, Intel, and Cisco.
Recent news from the smartphone business revealed 4,500 job cuts alongside a huge financial loss of $965m for Q2, $934 of which was due to what BlackBerry said was a "Z10 inventory change".
The company is now reportedly in talks about selling all or parts of itself to the highest bidders.
The 'preliminary expressions of interest' should come forward by early next week, according to sources.
At the time of sale, BlackBerry said that the talks were not exclusive and it was continuing to "actively solicit, receive, evaluate and potentially enter into negotations" with other potential buyers.
Following reports such as BlackBerry co-founder Mike Lazaridis warning fellow directors against the BlackBerry Z10 smartphone, it is unclear whether other tech companies will make bids.
"Possible bidders are proceeding with caution given the uncertainty around BlackBerry," Reuters reports.
According to Reuters, private equity firms have showed an interest in BlacBerry but have asked for additional financial details about its various business segments - which could take a few weeks.
