It is difficult to create differentiation especially involving functional benefits because a competitor will quickly copy or appear to copy or otherwise neutralize the advantage. Unless you brand it. A competitor cannot copy the brand. If the innovation is branded and the brand established, the competitor’s task of creating and communicating an enhancement will be formidable. When Westin created a superior bed and sleeping experience and branded it the Heavenly Bed, they changed the way that many looked at the hotel experience and the branded differentiator made it difficult for imitators to get traction.
