Mobii Systems Group Ltd, a Canadian technology company, has sued LIV Golf in the US District Court in Miami, according to ESPN's report of the filing. The complaint was lodged on Friday.

Everything that follows is an allegation contained in a civil complaint. None of it has been tested in court, and LIV Golf has not filed a legal response.

The claim

Mobii says it is owed more than $1 million, made up of three parts: $820,600 in unpaid licensing fees, $104,500 in usage fees for the current season, and $209,531 it says it will lose in revenue from the six remaining events of the 2026 season.

The last of those is the most interesting item, and the least straightforward. It is not a bill that went unpaid; it is money the company says it would have earned had the contract run its course. Claims of that type are common in contract disputes and are frequently the part that gets argued over hardest, because they require the claimant to prove what would have happened.

The product at issue is a broadcast feature called "Any Shot, Any Time." The contract was for two years and was due to expire on December 31.

What LIV said at the time

The complaint includes an email from LIV's senior vice president of technology, Nick Connor, dated May 25, telling the company the league would discontinue the service while it evaluated its "business model, our partnerships and our cost structure."

Connor added a line that will not help LIV's position on the money but does it credit on the substance: the decision "is not reflective of the quality of work or services provided."

In other words, LIV does not appear to dispute that the service worked. The dispute is about payment and about whether the contract could be ended early.

Why a million-dollar invoice is the story

A dispute of this size would normally not be news for a league that has spent billions on player contracts. It is news because of what surrounds it.

ESPN reports that Saudi Arabia's Public Investment Fund, which had put more than $5bn into LIV, stopped funding the league on April 30, and that the chief executive, Scott O'Neil, has been seeking $300m to keep it running.

Set against that, an unpaid supplier invoice reads less like a commercial disagreement and more like a symptom. LIV was founded on the premise that money was not a constraint. The complaint describes a league that paid this supplier throughout last year and stopped this year, then cancelled the service while reviewing its cost structure.

What happens next

Mobii must persuade a court that LIV breached the agreement and that the lost-revenue figure is recoverable. LIV may dispute the amount, the termination rights, or both, and has not yet said which.

For anyone watching LIV rather than the lawsuit, the number to follow is not the $1.1m claimed here but the $300m the league is reported to be seeking. This case matters mainly as evidence about the first question.
