A law firm in the North-East has helped national mobile phone company MonsterMob to acquire one of China's biggest providers of mobile content services.

Dickinson Dees, which employs more than 700 people in its Newcastle and Tees Valley offices, has overseen MonsterMob's acquisition of ATOP Century Ltd as part of a deal worth more than £100m.

Jeremy Swift, corporate partner at Dickinson Dees, advised Lancaster-based MonsterMob on all UK aspects of the deal as well as handling the legal advice given by MonsterMob's Chinese lawyers.

"Cross border transactions of this nature and size are complex deals," said Mr Swift.

"It's unusual for a firm outside the City to be involved in this sort of work, but we have the capacity to do this."

Phone entertainment group MonsterMob will use the acquisition to expand its international mobile content activities and plans to create a global mobile content business with more than 11 million subscribers.
