I had what reads like the same noise on my 04 Pat when it was under 6 months old. The cure my pro shop performed wastaking the limbsoff and lubing pockets. I saw him touch up one of the edges with a small file while he was at it.

It worked and hasn't creaked since. There was no way I could have hunted with that noise existing and relied on my back-up bow for the 1st 2 or 3 hunts of the season until the shop opened and i could get it cured.
