It seems that there's no clear standard regarding size & position of U+2117 (℗) and definitely not U+00AE (®). U+00A9 (©) is full cap size pretty much in all established fonts I've surveyed.

U+00AE (®) is almost always in superscript in practice, like with U+2122 (™), so it makes sense that some font designers choose to make it superscript by default (i.e. without sups feature enabled.)

U+2117 (℗) on the other hand seem to be used like U+00A9 (©), for example:
