The cat's real name is Tardar Sauce, who became famous in 2012 after photographs of her grumpy expression rocketed across the web.
As the Chicago Tribune points out, Grumpy Cat has appeared on The Ellen Show, Good Morning America, American Idol, and many other popular shows.
In the trial at California federal court Grumpy Cat Limited sued a U.S. coffee company Grenade after they broke the terms of an agreement over the use of the cat's image.
Her distinctive underbite and dwarfism became internationally recognised trademarks, sparking thousands of memes and gifs. She went on to star in the TV movie 'Grumpy Cat's Worst Christmas Ever, ' made several television appearances, and has a line of merchandise.
Still a sourpuss! Grumpy Cat's owner awarded more than $700000 in lawsuit after claiming beverage company
Grenade Beverage, a Californian coffee company, had paid $150,000 (£105,000) to launch one Grumpy-themed drink, but overstepped the mark by launching a second, the Washington Post reported.
She also has 1.42 million followers on Twitter, 2.4 million on Instagram and nearly nine million likes on Facebook.
There has been no reaction on the court victory from Grumpy Cat herself, except for a photo posted on social media.
But in 2015, Grenade chose to create a line of "Grumpy Cat Roasted Coffee", which was not part of the deal. The company said Grumpy Cat Limited's product manager "misrepresented the movie" in order to get Grenade into a deal, Courthouse News reports.
'Grumpy Cat feels vindicated and feels the jury reached a just verdict, ' said Grump Cat Ltd. lawyer, David Jonelis.
