I dunno what US patent law states but I would have thought it’s back dated to when it was applied.
The US didn’t do things that way until Nov 2000. Patents filed for before then were given a term based on their publication date. So sometimes applicants deliberately tied up their applications with filings and amendments to delay their publication date and give them a bit more time when the patent ca be enforced.
