OtterBox announced today that it has acquired fellow case maker LifeProof, one of its main competitors in the protective case market. “This is a big strategic move for us,” OtterBox CEO Brian Thomas said. He said the LifeProof name will remain part of the brand. Thomas cited the move as a way for OtterBox to get further into the waterproof case market — the company decided to integrate rather than compete with LifeProof. Interestingly, LifeProof just announced a new protective case — Frē for iPad mini.
