The complaint, filed Tuesday at U.S. District Court in Los Angeles, comes just 10 days before the first Exxxotica Expo in Los Angeles.
The fan show got its roots with Exxxotica Miami Beach, which just celebrated its fifth event, while Exxxotica New Jersey is gearing up for its third show in November.
Adultcon is gearing up for its 19th show in Los Angeles in September. For years, Adultcon has held its show at the same venue, the Los Angeles Convention Center.
Both shows feature exhibitors, including porn stars, showcasing products and services in the adult world.
In the complaint, Exxxotica said that registered its name with the U.S. Copyright Office in 2008 and that Adultcon operators "intended to divert customers ... for commercial gain and with the intent to tarnish or disparage the mark by creating a likelihood of confusion as to the source, sponsorship, affiliation and endorsement of the infringing sites."
Exxxotica counsel claims Adultcon's operator registered similar-sounding website names on Jan. 15, just months before Exxxotica announced it would be rolling out a show in Los Angeles.
The Adultcon-owned sites at the heart of the suit include Exxxotica-lv.com, ExxxoticaExpo-LA.com, ExxxoticaExpo-LV.com, ExxxoticaExpoLA.com, ExxxoticaExpoLV.com, ExxxoticaLA.com, ExxxoticaLasVegas.com, ExxxoticaLosAngeles.com, Exxxoticalv.com; ExxxoticaVegas.com; ExoticaExpo-LA.com, ExoticaExpo-LV.com, ExoticaExpoLA.com, ExoticaExpoLV.com, ExoticaLA.com, ExoticaLosAngeles.com, ExoticaLV.com, ExoticavaLasVegas.com and ExoticaVegas.com.
Each of the 19 domain names currently redirect to Adultcon.com.
The suit seeks not more than damages $100,000 for each alleged cybersquatted domain name.
Michael Fattorosi, who represents Exxxotica parent company Victory Tradeshow Management Group based in New Jersey, did not immediately return XBIZ calls for comment. Adultcon show organizer Renaud West also was unavailable.
