Doctrine, Data, and the Death of DuPont
Using large language models to analyze thousands of TTAB decisions, this paper demonstrates that the traditional thirteen-factor DuPont test effectively collapses to just two factors: mark similarity and goods relatedness predict outcomes with over 99% accuracy.
What They're Saying
This paper could be very useful... Empirical support for John Welch's mantra, which turns out to be understated: mark and goods don't predict 95% of the outcomes of 2(d) appeals to the TTAB, they predict 99%!
Rebecca Tushnet, Frank Stanton Professor of the First Amendment, Harvard Law School
The 13-factor DuPont analysis to determine likelihood of confusion is not as complex as it appears when practicing before the Trademark Trial and Appeal Board... Just two of the factors can be used to predict whether the board finds challenged marks confusing 99.57 percent of the time.
