Throughout history, people have come up with incredible inventions which have achieved global success without reaping the full rewards of their genius. Sir Tim Berners-Lee (pictured) famously refused to patent his invention more than 30 years ago, and never monetised it, instead gifting it freely to the world. Click or scroll through inventors who definitely could have got rich off their creations but, for various reasons, didn't.

In 1826, John Walker, a chemist from Stockton-on-Tees, England invented the first friction match and began selling cardboard matches packaged in boxes with sandpaper strike pads the following year. An instant success, word of Walker's invention soon spread. Walker steadfastly refused to patent his invention, ignoring advice from notable inventors of the time including Michael Faraday, and his matches were copied by all and sundry. Needless to say, Walker made very little money from his pioneering innovation. 

Jerry Siegel and Joe Shuster had spent years trying to find a publisher for their comics featuring a hero called Superman. So when they finally found one they didn't haggle over the price. They sold the rights to DC Comics for just $130 in 1937. Superman then became the most famous superhero of all time and comic books have gone on to become a billion-dollar industry. After protracted legal battles, in the late 1970s they were both given $30,000 (£15.4k) each a year for life and credits in all future Superman publications and movies. In 2012 the original $130 cheque sold at auction for $160,000 (£100k), with the money going to the heirs of a DC Comic employee who had stashed the cheque away for years.

László Bíró was lucky enough to have his invention named after him, at least in a generic sense, but not fortunate enough to make any serious money from it. The Hungarian-Argentine innovator patented the first commercially viable ballpoint pen in 1938. However, Bíró fled Nazi-occupied Hungary and escapted to Argentina in World War II, where he further perfected his invention. Losing his right to any future royalties, Bíró sold the patent to Marcel Bich in 1945, and Bich's Bic company went on to sell a staggering 100 billion of the pens.

 

Mikhail Kalashnikov developed the hugely successful weapon that bears his name during the mid-1940s in the Soviet Union. Still widely used today, the assault rifle is prized for its low production cost, reliability and ease of use. While Kalashnikov was lavished with awards and accolades from the Soviet authorities, including the Hero of Socialist Labor and Order of Lenin, the weapon pioneer didn't cash in on his invention. A diehard communist, Kalashnikov created the weapon for the good of the country rather than for his personal gain, and later he said he regretted the invention.

In the 1950s, Richard and Maurice McDonald invented a revolutionary way to make burgers better and quicker than anyone else. Then they met a down-on-his-luck salesman called Ray Kroc who convinced them to let them franchise it. Soon there were McDonald's outlets springing up all over the US, but trouble was brewing. In the end they agreed to sell the business for $2.7 million (£960k), but Kroc expanded the chain across the globe, making billions in the process.

In 1962, General Electric scientist Nick Holonyak, Jr. created the first practical LED light while attempting to create a laser, and he predicted the innovation would one day replace Edison's incandescent light bulb. Holonyak wasn't wrong, LEDs are ubiquitous these days. Sadly, their inventor didn't make any money from them and even missed out on a much-deserved Nobel Prize for the innovation.

The so-called 'Grandfather of Possibilities', American innovator Ron Klein has invented plenty of cash-generating things, but didn't make any money at all from his most famous invention, the magnetic credit card strip, which he developed in the 1960s. Klein's firm Ultronic Systems Corp. was granted a patent for his invention in 1969, but rival companies soon got in on the act, ripping off the technology and rolling it out worldwide. Ultronic never enforced the patent. As a result, Klein never made any cash from his innovation.

Obtaining a patent doesn't always protect your intellectual property from being imitated, especially if your patent runs out before the technology becomes commercially viable. Cue Douglas Engelbart. The computer pioneer filed a patent for the first mouse, a “position indicator for a display system”, way back in 1967. By the time the technology had gained serious commercial viability in the late 1980s, Engelbart's patent had expired and he made no money from the innovation.

 

Osaka-born innovator Diasuke Inoue came up with idea of karaoke (which translates as "empty orchestra") in the late 1960s when he started providing back-up tapes for businessmen to sing along to in bars. Inoue created the first makeshift karaoke tape and microphone machine in 1971, and the rest is history. But Inoue never patented his invention and made no money directly from it. Still, Inoue has received plenty of recognition, both positive and negative – the Japanese inventor won an Ig Nobel Prize in 2005 and Time magazine has described him as one of the most influential Asians of the 20th century.

British inventor Trevor Baylis developed the first wind-up radio in the early 1990s. A TV report on the spread of HIV in Africa inspired Baylis to create the radio, which he intended to be used to improve HIV awareness via radio educational programmes in parts of Africa with poor access to electricity. The London-born innovator filed his first patent in 1992, but actually made more money from the publicity surrounding the radio than from sales of the gadget itself. According to Baylis, large corporations circumnavigated his patents and were able to 'copy' his device and undercut him on price.

Programmer Alexey Pajitnov created the wildly successful Tetris computer game in 1994. An employee of the Soviet Union's Academy of Science, Pajitnov wasn't permitted to profit personally from his invention. Given its communist ideology, the Soviet government retained the rights to the popular game, and it wasn't until the collapse of the regime in the 1990s that Pajitnov was allowed to receive any royalties.

The creator of the Internet, Sir Tim Berners-Lee, is selling off the original code he used to create the World Wide Web in 1989 as an NFT (nonfungible token). The NFT is made up of four parts, including "the original time-stamped files" of the source code, a "an animated visualisation" of the code, a "digital poster" of the code created by Berners-Lee and a letter written by him.

His decision to sell off the code at a Sotheby's auction on 30 June has come as a surprise, although Berners-Lee and his wife Rosemary Leith have said they will donate the proceeds of the sale to good causes. But there is something more surprising about the sale...

Perhaps the most suprising aspect of the sale is the decision to sell the code as a NFT, as the unique form of digital ownership is known to be bad for the environment as NFTs are supported by a form of online ledger called a blockchain, which also supports cryptocurrencies. And so, in order to exist, NFTs and cryptocurrencies use a lot of electricity to power the blockchains through a network of computers.

It's been estimated by the founders of NFT website CryptoArt.wtf that the average NFT has a carbon footprint that matches the monthly footprint of the average EU citizen. Sotheby's is accepting cryptocurrency as payment for the lot.

The victim of cheap knockoffs, US inventor Shane Chen developed the first hoverboard in the early 2010s and was granted a patent for his self-balancing board in 2014. Chen marketed his Hovertrax creation for $1,000 (£600) a unit via crowd funding site Kickstarter and sales were buoyant for a time. Then Chinese counterfeiters and copycat firms started pumping out cheap copies of Chen's invention, despite the patent. They flooded the market with the budget imitations and, by the end of 2015, Chen's original version had pretty much flopped.
