Your Assignment Agreements May Be Outdated -- Take Action Now

May 2, 2011

The Federal Circuit's recent decisions on the assignment of future inventions have drawn a sharp distinction in what would appear to be minor difference in language that have major consequences and significance to ownership. The language turns on the difference in the phrase "agree to assign" and the phrase "do hereby assign." Under the Federal Circuit's interpretation, the former language ("agree to assign") is only a mere promise to assign inventions that are created in the future and requires a subsequent assignment agreement, while the latter ("do hereby assign") constitutes an immediate assignment when the invention is created in the future without the need of an additional assignment agreement. As reflected in recent Federal Circuit decisions, this difference in language can have severe consequences in determining who owns later issued patents.
