Tran said he was dissuaded from securing a trademark on the word sriracha since it is difficult to obtain one named after a real-life location. This has allowed others to develop their own versions, using the name. Some of the biggest corporations in the business, such as Heinz, Starbucks, Frito-Lay, Applebee's, P.F. Chang's, Pizza Hut, Subway, and Jack in the Box use the name without licensing it.[1][20] In 2016, Lexus partnered with Huy Fong Foods to build a single promotional Sriracha IS sport sedan.[21]
