The only perjury part is that you must be the copyright owner (or their representative) for the work you are claiming is copied. It isn't perjury to claim that the wrong thing is a copy - you simpyl allege that they copied it and it's upto the courts to decide.
So it is naughty for me to claim to represent the Beatles, it isn't for the Beatles' record company to demand that Das Boot be removed as it is a copy of the yellow submarine.
