Fizz Startup Sues Instacart and Partiful Over Trademark Infringement Dispute

Fizz, a social media startup focused on the Gen Z demographic and operating on over 400 college campuses, has initiated legal action against grocery delivery giant Instacart and event planning app Partiful. The lawsuit, filed in the U.S. District Court for the Northern District of California, accuses both companies of trademark infringement related to Instacart’s recent launch of a party-focused drinks and snack delivery app named Fizz.

Fizz claims it has been using the “FIZZ” trademark since January 2022 and filed for trademark registration in December 2021. The startup alleges that Instacart and Partiful’s use of the identical name in the same market segment—social and event planning services targeting Gen Z—creates a likelihood of consumer confusion and unfairly leverages Fizz’s brand recognition.

The lawsuit outlines several claims including common law and federal trademark infringement, cybersquatting, and violations of California’s unfair competition laws. Fizz specifically accuses Instacart of registering the domain fizz.com in bad faith to divert customers from Fizz’s official platform at fizz.social, aiming to profit from the startup’s established goodwill.

Partiful, which directly competes with Fizz in event planning, is also accused of using the Fizz name to confuse the Gen Z market after failing to gain traction through fair competition. Fizz argues that rather than competing on merit, Instacart and Partiful have chosen to exploit the startup’s brand equity by adopting its name for their new venture.

This legal battle highlights the challenges startups face in protecting their intellectual property against larger competitors entering overlapping markets. It underscores the importance of early trademark registration and vigilant enforcement to maintain brand identity and market position, especially in fast-moving sectors targeting younger demographics.

For tech startups and established companies alike, this case serves as a cautionary tale about the risks of brand dilution and consumer confusion when naming new products or services. It also illustrates the strategic role of legal action in defending market share and brand integrity in highly competitive environments.
