Picture a football (soccer ball) in your head and you probably see the cartoon ideal—a roughly spherical shape made with polygonal patches that are sewn together, usually in a familiar pattern of black and white. A great many balls were made along these lines for a great many decades.
Eventually, though, technology moved on. Footballs got rounder, smoother, and more colorful. This was seen as a good thing, with each new international competition bringing shiny new designs with ever-greater performance. That was, until things went too far, and the new balls changed the game. Thus was borne the “knuckleball” phenomenon.
We talk a lot about patent disputes in today’s high-tech world. Whether it’s Wi-Fi, 3D printing, or progress bars, patent disputes can quickly become big money—for lawyers and litigants alike.
Where we see less of this, typically, is the world of sports. And yet, a recent football innovation has seen plenty of conflict in this very area. This is the controversial story of vanishing spray.
Patently Absurd

You might have played football (soccer) as a child, and if that’s the case, you probably don’t remember vanishing spray as a key part of the sport. Indeed, it’s a relatively modern innovation, which came into play in international matches from 2013. The spray allowed referees to mark a line with a sort of disappearing foam, which could then be used to enforce the 10-yard distance between opposing players and the ball during a free kick.
The product is a fairly simple aerosol—the cans contain water, butane, a surfactant, vegetable oil, and some other minor constituents. When the aerosol nozzle is pressed, the liquified butane expands into a gas, creating a foam with the water and surfactant content. This creates an obvious white line that then disappears in just a few minutes.
The spray was created by Brazilian inventor Heine Allemagne in 2000, and was originally given the name Spuni. He filed a patent in 2000, which was then granted in 2002. It was being used in professional games by 2001, and quickly adopted in the mainstream Brazilian professional competition.
The future looked bright for Allemagne and his invention, with the Brazilian meeting with FIFA in 2012 to explore its use at the highest level of international football. In 2013, FIFA adopted the use of the vanishing spray for the Club World Cup. It appeared again in the 2014 World Cup, and many competitions since. By this time, it had been renamed “9.15 Fair Play,” referring to the metric equivalent of the 10-yard (9.15 meter) distance for free kicks.

The controversy came later. Allemagne would go on to publicly claim that the global sporting body had refused to pay him the agreed price for his patent. He would go on to tell the press he’d knocked back an initial offer of $500,000, with FIFA later agreeing to pay $40 million for the invention. Only, the organization never actually paid up, and started encouraging the manufacture of copycat products from other manufacturers. In 2017, the matter went to court, with a Brazilian ruling acknowledging Allemagne’s patent. It also ordered FIFA to stop using the spray, or else face the risk of fines. However, as is often the way, FIFA repeatedly attempted to appeal the decision, raising questions about the validity of Allemagne’s patent.
The case has languished in the legal system for years since. In 2020, one court found against Allemagne, stating he hadn’t proven that FIFA had infringed his products or that he had suffered any real damages. By 2022, that had been overturned on appeal to a higher court, which found that FIFA had to pay material damages for their use of vanishing spray, and for the loss of profits suffered by Allemagne. The latest development occurred earlier this year, with the Superior Court of Justice ruling that FIFA must compensate Allemagne for his invention. In May, CNN reported that he expected to receive $40 million as a result of the case, with all five ministers on the Superior Court ruling in his favor.
Ultimately, vanishing spray is yet another case of authorities implementing ever-greater control over the world of football. It’s also another sad case of an inventor having to fight to receive their due compensation for an innovative idea. What seems like an open-and-shut case nevertheless took years to untangle in the courts. It’s a shame, because what should be a simple and tidy addition to the world of football has become a mess of litigation that cost time, money, and a great deal of strife. It was ever thus.

The good old fashioned game of football used to be a simple affair. Two teams of eleven, plus a few subs, who were all wrangled by a referee and a couple of helpful linesmen. Long ago, these disparate groups lived together in harmony. Then, everything changed when VAR attacked.
Suddenly, technology was being used to adjudicate all kinds of decisions, and fans were cheering or in uproar depending on how the hammer fell. That’s only become more prevalent in recent times, with smart balls the latest controversial addition to the world game. With their starring role in the Euro 2024 championship more than evident, let’s take a look at what’s going on with this new generation of intelligent footballs.
Another week in football, another VAR controversy to fill the column inches and rile up the fans. If you missed it, Coventry scored a last-minute winner in extra time in a crucial match—an FA Cup semi-final. Only, oh wait—computer says no. VAR ruled Haji Wright was offside, and the goal was disallowed. Coventry fans screamed that the system got it wrong, but no matter. Man United went on to win and dreams were forever dashed.
Systems like the Video Assistant Referee were brought in to make sport fairer, with the aim that they would improve the product and leave fans and competitors better off. And yet, years later, with all this technology, we find ourselves up in arms more than ever.
If you are a certain age, you probably remember the Mattel Football game. No LCD screen or fancy cartridges. Just some LEDs and a way to play football when you should be in class. While these might seem primitive to today’s kids, they were marvels of technology in the 1970s when they came out. [Sean Riddle] looks, well, not exactly at the games, but more like in them. As it turns out, they used chips derived from those made for calculators.
[Sean’s] post is a glimpse into this world of over four decades past. Football was actually the second electronic game from Mattel. The first one was Auto Race. There were also games called Space Alert, Baseball, and Gravity. Inside each are quad in-line packages with 42 pins, a Rockwell logo, and a custom part number.
If you’re a die-hard sports fan, there’s nothing you love more than staying abreast of developments in the league, from top to bottom. [Kiu] had a family member that was big into NFL, so set about building them a remarkably cool ladder tracker.
The tracker displays the NFL league table with a ten-minute delay, thanks to a paid live data feed from MySportsFeeds.com. When an update comes in, miniature helmets representing each team in the competition are moved into the correct order. The helmets sit on little plastic tags that make moving them easy, reliable, and repeatable. Built using parts familiar to the 3D printer world, this tracker relies on steppers and V-rails for linear movement, under the command of an Arduino Nano.
It’s a build that would look great in any games room, and we bet a scaled-up version would look the business in an upmarket sports bar. Let’s be honest – the league’s top quarterbacks will all be fighting to have one of these sooner rather than later. That’s not to say it won’t sting to come home to your team’s helmet scooting down the board after a painful loss!
If you are an American, you’d probably think of [Silas Hansen’s] project as “air soccer” but most people will prefer air football. Either way, it is like air hockey but more of a football field feel. The project looks great — if you saw this on the shelves of the local toy store, you wouldn’t think anything of it. You can see a video of the game in action, below.
Unsurprisingly, the brains of the game are an Arduino. The case looks good thanks to laser cutting and 3D printing. A Roland printer produced the stickers that really dress the case up, but you could find another artistic way to do the decoration.
