The mother of slain Florida teen Trayvon Martin is reportedly seeking to trademark phrases that have become headlines among supporters who feel he was unjustly killed, a victim of deadly racial profiling, in part because he was wearing a hoodie at the time of the confrontation.

George Zimmerman, the neighborhood watch volunteer who killed Martin in Sanford Feb. 26, has not been charged with the death, and is reportedly in hiding.

According to The Smoking Gun, Martin's mother Sybrina Fulton submitted trademark applications for the phrases I am Trayvon and Justice for Trayvon on March 21 with the United States Patent and Trademark Office. (It should be noted that Fulton's name is spelled Sabrina in the USPTO documents, where elsewhere it is spelled Sybrina.)

Fulton is seeking trademarks for the use of the phrases on digital materials, namely, CDs and DVDs featuring Trayvon Martin, and downloadable audio and video recordings. The applications - which cost $325 each to file - do not mention T-shirts, sweatshirts or other merchandise.

Martin was shot in the chest at close range by Zimmerman, who claims he was acting in self-defense, but serious questions remain about whether his use of a firearm was justified. Martin was unarmed, carrying only a pack of Skittles candy and a bottle of iced tea.

Police did not charge Zimmerman, who remained at the scene as paramedics arrived. Zimmerman did allow himself to be questioned by police on multiple occasions, including the night of Feb. 26, according to the Orlando Sentinel.

Zimmerman reportedly stood by his self-defense claim, insisting that Martin punched him in the nose, pushed him to the ground, and beat him before he retaliated. According to the Sentinel, eyewitness accounts corroborate Zimmerman's story.

On March 12, ABC News uncovered questionable police conduct in the investigation of Martin's death, including at least one instance where witness reports were edited after the fact.

Numerous petitions demanding Zimmerman's arrest are currently circulating, and multiple vigils have been held in Martin's honor. On March 21, Martin's parents joined hundreds of protesters in New York City for The Million Hoodie March, which was organized to demand Zimmerman be held accountable for the killing.

The phrases I am Trayvon and Justice for Trayvon have been widely circulating on petitions and social media tributes to the slain 17-year-old.

On Monday, the Sentinel reported that at the time of his death, Martin was suspended from school after he was discovered to be carrying a bag with trace amounts of marijuana.

Martin family lawyer Benjamin Crump addressed the marijuana charges at the start of a press conference Monday.

The family has said, 'What does that have to do with him killing my son? What does it matter?' Crump said. It's completely irrelevant what Trayvon Martin was suspended for on Feb. 26.

They killed my son and now they're trying to kill his reputation, Fulton added.
