Is there a difference between pattern and pattern regular?
There is. The Pattern is slightly deeper at the nut and the fretboard is ever so slightly wider. I also thing the geometry is slightly different. I feel like the Pattern Regular have slightly more pronounced shoulders, while the Pattern tapers off towards the edges a bit less gradual. Because of the aforementioned geometric differences, I don't feel the chunkiness of the Pattern as much as I feel with the Pattern Regular. However, I have no official source regarding the geometry, so I'm merely stating my experience with these necks. I cannot reject the possibility that this "geometric" difference is not a result of an actual difference in shape itself, but entirely a function of the fretboard width. It's almost like the Pattern shape resembles a Medium V shape, whereas the Pattern Regular is more in line with the more traditional C shape. Regardless, of the source of the minor differences, the Pattern feel better to me than the Patter Regular. With that said, both those carves are extremely comfortable and just a joy to play.

WIDTH OF THE FRETBOARD AT THE NUT:
Pattern, Wide Fat - 1 11/16” = 1 22/32"*
Pattern Thin, Wide Thin - 1 11/16”
Pattern Regular, Regular - 1 21/32”
Pattern Vintage - 1 11/16”
JM – 1 21/32”
12 String - 1 47/64”
WIDTH AT THE BODY
Pattern, Wide Fat - 2 1/4”
Pattern Thin, Wide Thin - 2 1/4”
Pattern Regular, Regular - 2 1/4”
Pattern Vintage - 2 1/4”
JM – 2 7/32”
12 String - 2 19/64”
NECK DEPTH AT THE NUT
Pattern, Wide Fat - 28/32”
Pattern Thin, Wide Thin - 26/32”
Pattern Regular, Regular - 27/32”
Pattern Vintage - 57/64” = 28.5/23"
JM – 53/64”
12 String - 27/32”
* Re-expressed the dimension for ease of comparison (22/32 = 11/16, and 57/64 = 28.5/32).
** Summary of differences: Pattern is 1/32" wider at the nut relative to Pattern Regular. Pattern is 1/32" deeper at the nut relative to Pattern Regular. Width at the body are the same.
*** Note: There is a picture floating around from reliable sources that state the Pattern Depth at the nut at 27/32", which is equal to the depth at the nut of the Pattern Regular spec. Clearly one of the two sources have a small typo. I, however, am not certain which source is correct, i.e. typo free. The reason for that is that I notice the depth of the neck less between the Pattern Regular and Pattern compared to the Pattern Thin, which cording to the PRS support page are both 1/32" apart. Also, I noticed the difference between the Pattern and Pattern vintage (0.5/32" according to the support page) more than the supposedly 1/32" difference between the Pattern and Pattern Regular.
