Nike says that Rob Gronkowski’s logo looks too similar to the Jumpman — the most recognizable brand logo in professional sports.

Nike filed a formal opposition to the United States Patent and Trademark Office Trial and Appeal Board earlier this month, according to ESPN’s Darren Rovell. Gronkowski’s team can abandon the trademark or respond to Nike by Aug. 5.

If you take a look at the two logos side by side, Gronkowski’s does pose a resemblance. A quick glance at the Gronkowski logo, and you might think it was one of those awful logos put on a bootleg Air Jordan sneaker or a child’s attempt at drawing the Jumpman.

Gronkowski’s logo can be found on his “Gronk Fitness” website where you can purchase equipment and workout apparel.

It has a subscription option with a “spike” button instead of “submit.”

It can also be found on his “Gronk Bus” logo, which is his version of a party bus. All of this is on brand for Gronkowski.

The trademark was filed by Gronkowski’s company, Gronk Nation L.L.C., in April of 2016, per Rovell. The company sounds set on finding some type of solution, while maintaining his brand.

“My client has created one of the most recognizable brands in sports today,” said attorney Troy Carnrite, who represents the Gronkowski family. “We are very proud of this brand and are optimistic that we will resolve this with Nike amicably.”

Gronkowski wears Nike cleats on the field, and his uniform is also covered in Nike swooshes because of its partnership with the NFL. The Jumpman logo has been in use by Nike since November 1987, making its first appearance on the Air Jordan 3.

Whether Gronkowski decides to keep his logo or drop it, don’t be surprised to see some knockoff Jordans with the Gronkowski logo on them.
