What are the Priority Date, Patent Term, and Effective Filing Date of a Patent: The Roles of Specific Reference, Incorporation by Reference, and Claim Support

A recent Federal Circuit decision demonstrates that for priority claims and patent term, the phrase “specific reference” is key. For example, amongst three related applications, to get the benefit of priority of an earlier U.S. patent application 1, application 3 in a priority claim has to have a “specific reference” to earlier application 1. A mere priority claim in application 3 to application 2, even though application 2 specifically “incorporates by reference” application 1, is not sufficient to allow application 3 to rely on the filing date of application 1. Rather, the priority chain is broken between applications 2 and 1, leaving application 3, at best, with a priority date of application 2 for purposes of patentability… From the Federal Circuit in Droplets, practitioners are reminded that both priority claims and incorporation by reference are very specific tools that should not be relied on during prosecution without careful consideration and deliberate use. Certainly, incorporation by reference does not trump “specific reference” and may lead to a break in the priority chain for purposes of patentability.
