Also, reading the listing, I see
2020-03-06 - Anticipated expiration
2020-03-08 - Application status is Active
Is "active" some kind of obscure reference with a nonintuitive meaning, or did the patent owner reapply for the patent?
- mkl 7y agoYou can't reapply for patents like that, but I don't know what that status means. Patents often get an adjustment to their term and last a bit more than their nominal 20 years (due to delays being issued, etc.). https://en.wikipedia.org/wiki/Term_of_patent https://en.wikipedia.org/wiki/Term_of_patent
- lifthrasiir 7y agoI was also a bit confused, but it turns out that the last line is always dated today (in the local time zone ;-) and displays the last known status, which may be, and in this case definitely is, outdated.
