New Jersey resident Jeffrey Marder filed a class action lawsuit against Nintendo, The Pokémon Company, and Niantic Labs on Monday, claiming that the game Pokémon Go entices players to trespass by placing Pokéstops and gyms on private property without the owners’ permission. The lawsuit seeks compensation and a change in the game’s practices.

The lawsuit states that, since the game’s launch, Marder has seen strangers loitering around his house with their phones, and that “at least five individuals” have knocked on his door to request access to his yard in order to catch Pokémon.

The lawsuit also cites other cases similar to Marder’s, as well as the placement of Pokéstops at the United States Holocaust Memorial Museum. The museum is one of several sites that have requested their locations be removed from the game.

Niantic’s game update last weekend added safety warnings and advisories against trespassing.
