If we're all going by how sincere Palpatine was to Anakin, then he lied.
"Unfortunately, he taught his apprentice everything he knew, then his apprentice killed him in his sleep."
If Palpatine was Plagueis's apprentice the he should already know how to create life. But if him saying to Anakin:
"To cheat death is a power only one has achieved, but if we work together, I'm sure we can discover the secret."
If that's true, then he lied to Anakin before. Ruling out Palpatine's part in Anakin's creation. And if he was being as sincere as he's being made out to be, then it would rule him out as Plagueis's apprentice altogether.
But if he really is his apprentice, then he was simply using the creating life and stopping death line as a way to hook Anakin's interest in the Dark Side, which is what happened.
But I'm no scholar on CW and Plagueis paraphanalia, so if something in the books contradicts this, then woops.
