I can’t get the “cha-ching” sound of a cash register out of my head.

MARCH 26 (TSG) — The mother of Trayvon Martin has filed two applications to secure trademarks containing her late son’s name, records show.

Sabrina Fulton is seeking marks for the phrases “I Am Trayvon” and “Justice for Trayvon,” according to filings made last week with the United States Patent and Trademark Office. In both instances, Fulton is seeking the trademarks for use on “Digital materials, namely, CDs and DVDs featuring Trayvon Martin,” and other products.

The March 21 USPTO applications, each of which cost $325, were filed by an Orlando, Florida law firm representing Fulton.

Martin, 17, was shot to death last month during a confrontation with George Zimmerman, a 28-year-old neighborhood watch captain. Martin, pictured above, was visiting his father’s home in Sanford, Florida when he was shot to death by Zimmerman, who has claimed that he was acting in self-defense.
