Representatives of Wynn Resorts believe the Resorts World property being built across the street looks a lot like Wynn Las Vegas and Encore.

“You can, in fact, copyright the design of a building as an architectural work,” said Mark Lemley, director of Stanford University’s program of law, science and technology.

“Wynn might have a trademark claim if it can show that people associate that design exclusively with them and that seeing a similar building serving a similar purpose will confuse consumers into thinking this, too, is a Wynn hotel,” he said.
