Two specialist technology firms lined up alongside Hogan Lovells on the acquisition by Zynga of the maker of Draw Something, an app that allows users to play a Pictionary-style game on their smartphones.
The much-discussed $200m (£125m) deal, announced last month, saw the acquisitive social network game developer take control of OMGPOP, which launched the Draw Something just six weeks before the transaction.
Draw Something enables friends to draw pictures and and exchange them, with the recipient then guessing what the sender has drawn.
It has been hugely successful, and last month was reported to have become the most-used app on the Facebook platform.
Zynga turned to technology firm Cooley, which fielded Palo Alto corporate partner Jennifer Fonner DiNucci as the lead.
OMGPOP hired Gunderson Dettmer Stough Villeneuve Franklin & Hachigian corporate partner David Van Horne in Silicon Valley and New York associate Daniel Goldberg.
Gunderson Dettmer, which specialises in technology ventures capital funds and startups, has worked for OMGPOP since its launch in 2006.
Gunderson Dettmer also brought in Hogan Lovells partner Michele Harrington for antitrust advice.
