We’ve all been there. Maybe we find it in reviewing the chain of title for trademarks during due diligence. Maybe it’s something that another company filed that has nothing to do with us. Or maybe someone on your team made a typo (yup, no one is perfect!). But, however it happened, it’s there, in the USPTO records: an assignment inadvertently recorded against a registration that was not actually part of the assignment; a security interest recorded against the wrong application number; or a name change was erroneously recorded as a merger. Regardless of why or what, the bottom line is the same: there is an error in the chain of title for the application or registration. Oops! Now what? How do we get that error fixed and removed from the USPTO trademark records?
