Cleary Gottlieb Steen & Hamilton is advising Alphabet Inc.’s Google on the $1.1 billion acquisition of Taiwanese smartphone maker HTC Corp.’s Pixel division.

In an all-cash deal announced Thursday, the search engine giant has agreed to acquire a 2,000-employee research and development and a non-exclusive patent license from HTC. The latter’s R&D team—the equivalent of half of HTC’s R&D division—makes the Pixel smartphone that Google launched last year to challenge Apple Inc.’s iPhone.
