"Some lawyers say Pokemon Go, an “augmented reality” game, raises legal issues and public safety concerns. Alabama lawyer Keith Lee, writing at his Associate’s Mind blog, says his legal questions include: Does placing a Pokemon character on a private property, without permission, affect the owner’s interest in exclusive possession of the property? Does it create an attractive nuisance? Does owning real property extend property rights to intellectual property elements that are placed on it? Is there liability for placing the characters on private property or in dangerous locations? Michigan lawyer Brian Wassom raises other legal issues in a post for the Hollywood Reporter’s THR, Esq. blog. Augmented reality games can lead to competition for the use of the same physical spaces, disrupting the ability of players and nonplayers to enjoy the place, and possibly leading to violence, he says. Could government limit the players in a public space? Would that bring a First Amendment challenge?"
