The suits were filed in the UK, Italy and Germany.
Ericsson says it made multiple attempts to get ZTE to sign a patent licensing agreement, but the sides could not come to terms. The company says it has been trying for years to get the deal signed and that the suits are "a last resort."
The UK and Italian suits are solely over handset patents while the German one includes handset and network patents.
Ericsson would not reveal which specific patents were up for debate.
