The search engine company would also need approval from China, besides regulators in Israel and Taiwan
Google is likely to receive an approval next week from European regulators and US antitrust authorities for its proposed acquisition of Motorola Mobility.
European regulators approval is set to coincide with the decision by the US Justice Department approving the deal, according to Reuters.
Google had announced last August that it will acquire Motorola Mobility in a deal worth $12.5bn.
The search engine company says the move will enable it to "supercharge" the Android ecosystem and boost its patent portfolio, protecting it from threats posed by Microsoft and Apple products.
Android will remain an open source platform, according to Google.
Motorola, which will remain a licensee of Android, will be run as a separate platform.
Motorola Mobility, which focuses on smartphones and tablets, was hived off from Motorola earlier this year.
The Commission could announce its decision on Monday, a month later than originally planned.
Once the deal is approved by the US and European authorities, Google would need approval from China too, which has to take a decision before March 20.
Besides, regulators in Israel and Taiwan would also have to approve the deal.
