The lawsuit dated Dec. 8, 2009, and filed in U.S. District Court was obtained by Fox 5 San Diego. It claims "intentional interference with contract and unfair competition as well as trademark infringement'' because Tequila, whose real name is Tila Nguyen, used Merriman's famous "Lights Out'' logo on her Web site.
Merriman filed his lawsuit three weeks after Nguyen filed a $1.5 million lawsuit against Merriman, claiming assault, battery, false imprisonment and emotional distress.
The feud between the former couple stems from an incident at Merriman's Poway home in September. Sheriff's deputies were called to the home Sept. 6. They took Merriman into custody after Nguyen signed a citizen's arrest warrant accusing him of battery and false imprisonment. He was released a short time later.
District Attorney Bonnie Dumanis later declined to press charges, finding there was "insufficient evidence to prove beyond a reasonable doubt that any crime was committed.''
The 6-foot-4, 280-pound Merriman said he was protecting the 4-foot-11, 93-pound woman because she was intoxicated and wanted to drive home. Tequila -- whose real last name is Nguyen -- denied being drunk.
On the same early morning of the attack, the couple was spotted partying at Stingaree nightclub in downtown San Diego, where Nguyen was photographed giving Merriman a lap dance.
According to Merriman's suit, Nguyen posted all sorts of lies on her Web site, including stories that the linebacker "choked and attacked'' her, "sleeps with minors and forces them to take drugs,'' and that he manufactures drugs in his Poway home.
Merriman also claims in his suit that Nguyen admitted her lying scheme, at one time saying, "yes, that is why I did a `spin' now ... cuz now everyone is LOVINGGGG me for all this sports talk and they are now like f**k chargers N Shawne.''
Merriman is not suing Nguyen for defamation. Instead, he is claiming damage to his business interests through copyright and trademark infringement. The suit claims that Nguyen's actions are damaging his NFL contract with the Chargers a contract for a t-shirt line with Wal-Mart and potential sponsorship relationships with other unspecified companies. The lawsuit requests a jury trial to determine real and punitive damages.
The suit alleges that Nguyen admitted she was trying to ruin his relationship with the Chargers, saying in a posting that if the controversy "is causing too much distraction for their football, they will kick him out. AJ the GM for the team is already sick of him."
Nguyen starred in two installments of an MTV dating show called "A Shot At Love.'' In the show, male and female contestants vied for Nguyen, who is bisexual.
