You may have noticed something of a steady stream of posts from us on the topic of a "Taco Tuesday" trademark held by the chain Taco John's. Taco John's has used this descriptive trademark to bully all kinds of other restaurants into not advertising their own taco Tuesday offerings, while also leaving alone the vast majority of small purveyors of tacos on Tuesdays. The ubiquity of Taco Tuesdays is mostly what has everyone confused as to why Taco John's is acting like Taco Jerks: the term is descriptive and, even if it weren't, fully generic at this point.

It was enough to, and I can't believe I'm saying this, get LeBron James involved. You see, just like dragons, LeBron loves tacos. And he likes promoting his own consumption of tacos on Tuesdays and he very much thinks that everyone should be able to use the phrase as they please. To that end, LeBron took to the Trademark office pretending to want to trademark "Taco Tuesday" for himself when he was actually hoping to get denied due to the generic and descriptive nature of the mark... which is exactly what happened. We said then that it was now only a matter of time before someone decided to go on the offensive to take Taco Tuesday back by inviting Taco John's to issue a threat so that this hero group could point to the Trademark Office's denial of LeBron's trademark, with the ultimate goal being invalidating the Taco John's trademark.
