Jennifer Armour sued the R&B star last year, claiming that the 2003 hit song "Baby Boy," from Beyonce Knowles' Grammy-winning album "Dangerously in Love," took lyrics from her own song, "Got a Little Bit of Love For You."
Armour said her former manager submitted demo recordings of her song to various studios including Columbia Records and Atlantic Recording Corporations, record labels for Knowles and Sean Paul, who is featured in the song.
However, the court did a side-by-side comparison of the two songs to look for substantial similarity — a key component of copyright infringement — and found they were "substantially dissimilar."
"It's unfortunate that lawsuits such as this one occur, but I am grateful and relieved to have this behind me and I am eager to move on," Knowles, a Houston native, said in a statement issued by Music World Entertainment, the music management company her manager father founded.
Armour could not be reached for comment.
