I looked through the entire 1412.03 and 35 USC 251, couldn’t find about chaining and 18 months. I thought I missed it, can somebody clarify this, pl?

Thanks in advance.

agree
couldn’t find anything in 35 U.S.C. 251 either
not only about 18 months but about “chaining” in general (

Its confusing the way 1412.03 is summarized above:

1412.03: Steps for rejecting recapture claims:

1. 35 U.S.C. 251: Remember: There is a 2 year limit from the original issue on the time to make a reissue app if it is going to broaden claims. However, reissue apps can be chained together as long as they are all broadening so: Original app + 18 month for 1st broadening reissue app + 18 months for 2nd broadening reissue app is allowable even though the final reissue app is > 2 years after the original issuance date.

The MPEP states it as 2 years, not 18 months… Am I missing anything?

Regarding 1453: Amending Reissue Apps: (see 37 CFR 1.173(b)-(g); 37 CFR 1.121(i)):

When omitting, [put omitted material in brackets]; Why no strikethrough? Probably because the strikethroughs are preserved from the original patent? or some other reason?

Maybe its because for reissue the marked-up version is published and strikethrough is a little more difficult to read? At least that makes sense to me and will help me remember…
