Automatically calculate expiration date
Would be helpful if AppColl could automatically calculate the expiration date of a patent once the issue date and PTA have been entered.
@RichardS3059 Fair enough that AppColl won't be able to accurately calculate every expiration date. But it could still calculate a default date that will be correct for most patents. Even a human can't calculate the expiration date at issue accurately if the patent later becomes eligible for PTE.

@BerndN5890 You'd have to remember that the calculated date could be incorrect if a terminal disclaimer was in place. Or if PTE was granted under Hatch Waxman. And, of course, non-payment of maintenance fees. And that's just for US patents. For foreign patents, it's even more complicated.
