Oasis vs. Kevin Rudolf

According to the Wikipedia entry for Kevin Rudolf’s “Welcome to the World”  “the melody of the chorus is taken from the 1994 Oasis song [Supersonic]”. I’m not even sure what this means. Does that mean he “stole” it?? Have a listen.

Oasis - "Supersonic" (1994)

Kevin Rudolf - "Welcome to the World" (2009)
