SAN FRANCISCO — Skybox Imaging Inc., a Mountain View-based satellite imaging company, turned to Fenwick & West for counsel on its acquisition by Google for $500 million.

Launched in 2009, Skybox makes satellites that are smaller and more affordable than traditional models and raised $91 million from investors such as Khosla Ventures, Bessemer Venture Partners, Canaan Partners and Norwest Venture Partners, according to its website.

The companies announced the all-cash deal Tuesday. Google said in a statement that the acquisition “will help keep Google Maps accurate with up-to-date imagery.” The search giant, which has launched initiatives to bring Web access to remote areas, said the purchase of Skybox will also help the company “improve Internet access and disaster relief.”

The Fenwick team advising Skybox included corporate attorneys Daniel Dorosin, Andrew Luh, Scott Behar, Julia Forbess, Patrick Grilli and Elena Coleman; executive compensation and employee benefits attorneys Gerald Audant and Kelli Newman; technology transactions attorneys Stephen Gillespie and Madeline Zamoyski; antitrust attorney Mark Ostrau and tax attorneys Andrew Kim and Zach Jones.

It was not immediately clear who represented Google in the transaction, one of its largest private-company acquisitions ever. The deal is subject to customary closing conditions, including regulatory approvals.
