Tesla is suing a supercapacitor company in Australia for patent infringement, despite the automaker’s pledge that “all our patents are belong to you.”
But Tesla’s pledge to open its patents came with a very important requirement that this company didn’t respect.
In a now-famous blog post called “All Our Patent Are Belong To You,” Elon Musk announced that Tesla is open-sourcing all its patents in 2014.
It was a surprising move coming from a publicly traded automaker, but it came with some requirements that made this a smart business move.
Rather than traditionally open-sourcing its technology, Tesla, instead, made a pledge to “not initiate patent lawsuits against anyone who, in good faith, wants to use its technology.”
More specifically, Tesla meant by “good faith” that anyone using its patented technology cannot sue Tesla for patent infringement. This made the offer significantly less attractive to companies as it meant that if it used Tesla’s technology, it would open the door for Tesla to use theirs since they wouldn’t be able to sue them.
Nonetheless, some companies were believed to have taken Tesla up on the offer. While Tesla has sued other companies over claims to have stolen trade secrets in the past, it hasn’t gotten into patent infringement lawsuits until now.
Last week, Tesla filed a patent infringement lawsuit in Texas federal court against Australia’s Cap XX, a supercapacitor company.
The automaker claims that Cap XX infringes on some patented electrode technology used in supercapacitors – a technology that Tesla has acquired through its acquisition of Maxwell.
Tesla wrote in the lawsuit (via Reuters):
Maxwell has a history of innovation that has resulted in its own patents, now assigned to Tesla, and thus Tesla brings this suit against Cap-XX to protect its intellectual property rights.
But why is Tesla suing if it pledged not to? Tesla says that the legal action is “in response” to Cap XX having filed a patent infringement claim against Tesla’s Maxwell back in 2019.
That’s in line with Tesla’s patent pledge. Cap XX’s lawsuit is still ongoing in Delaware federal court. In the new lawsuit, Tesla is asking the court for an unspecified amount of money in damages.

On today’s downright giddy episode of Quick Charge, at least one Cybertruck owner is sick of people making fun of his ride – but Tesla won’t let him trade it in. Plus, the Associated Press reports that Tesla is suing its own customers, and Nissan is adding AI to its EVs to its record time.
Bloggers and journalists might be in trouble if they keep writing about Tesla’s shortcomings – especially in China, where the company has allegedly been using its pull with the government to put pressure on journalists to keep their spin on the company positive. We’ve also got some new pics of the upcoming 2026 Nissan LEAF and a story about the rising cost of solar under Trump’s second administration.
New episodes of Quick Charge are recorded, usually, Monday through Thursday (and sometimes Sunday). We’ll be posting bonus audio content from time to time as well, so be sure to follow and subscribe so you don’t miss a minute of Electrek’s high-voltage daily news.

The Nature Conservancy (TNC) and the Cumberland Forest Limited Partnership are turning former Appalachian coal mines into clean energy hubs. They just announced new agreements with Sun Tribe Development and ENGIE to build 14 solar farms and three battery storage systems across 360 acres in Virginia, Tennessee, and Kentucky.
This marks the second round of clean energy projects launched under TNC’s Cumberland Forest Project.
These projects aren’t just about clean energy – they’re about proving that clean energy can be developed on former Appalachian coal mines in a way that benefits the environment and local communities. The solar and storage hubs are expected to bring in more local tax revenue, create short-term construction jobs, and establish a community fund to support additional local initiatives.
Brad Kreps, TNC Clinch Valley director, said, “Developing projects on former coal mines – and in a way that engages with people in the local area so that communities can benefit – takes ingenuity, skill, and determination. Ultimately, we selected Sun Tribe and ENGIE, two experienced developers that have a great interest in bringing this vision to life.”
Once online, these projects will generate around 49 megawatts (MW) of solar energy and 320 MW of battery storage – enough to power 6,638 Appalachian homes annually.
Sun Tribe’s projects will be in Virginia and Tennessee. It’s planning one 5 MW solar project and three utility-scale battery storage systems ranging from 80 MW to 150 MW. These storage projects will improve grid reliability and help cut costs for utility customers by reducing the need for future grid upgrades.
“Locating solar and battery storage on former mine lands makes perfect sense to us,” said Danny Van Clief, CEO of Sun Tribe Development. “These sites and the communities they rest within have powered our country for more than a century – all we have to do is reimagine them for today’s energy technology.”
ENGIE, meanwhile, is developing 13 community-scale solar projects across Virginia, Tennessee, and Kentucky that will take advantage of Inflation Reduction Act incentives to help keep costs down. They’ll range in size from 1 MW to 6 MW, bringing clean energy access to more local communities.
“ENGIE is thrilled to collaborate on the development of these projects with The Nature Conservancy,” says Kristen Fornes, ENGIE head of distributed solar and storage. “These initiatives not only contribute to the reduction of greenhouse gas emissions but also generate employment opportunities, rejuvenate local communities, and enhance access to clean energy in areas where it is most needed.”
This latest announcement builds on previous first-round work by TNC, Sun Tribe, and Dominion Energy to bring renewable energy to Appalachia. Since 2021, Sun Tribe and Dominion Energy have been working on plans to generate 140 MW of renewable energy across eight sites in the Cumberland Forest. The first project, Wildcats Solar, is a 10 MW array planned for Wise County, Virginia. Expected to start construction by 2026, it’s projected to generate $800,000 in tax revenue for the community over its lifetime. Additional projects from the first round are set to be online by 2029.

The most interesting one is “Armored Tesla (Production Units)”, which is worth $400 million. Strangely, the item is listed under the NAICS code “311999 – All Other Miscellaneous Food Manufacturing.”
The program has a target for delivery in Q4 through the next 5 years.
There are several other similar and strange budgeted items that are linked to the wrong categories:
You have “ARMORED SEDAN” under “Soft Drink Manufacturing,” “ARMORED BMW X5/X7” under “Bottled Water Manufacturing,” and finally, ARMORED EV (NOT SEDAN) under “Ice Manufacturing.”
However, all these other armored vehicle-related items are budgeted at a fraction of the $400 million for Tesla vehicles ($50 million, $40 million, and $40 million, respectively).
The State Department procurement forecast website mentions that the list was last updated in December – before Trump entered office.
Electrek has contacted the State Department for a comment, and we will update you if we get an answer.
Tesla has claimed that its Cybertruck is “armored” and “bulletproof”, but its armored capacity is quite limited. It can likely deflect low-velocity bullets if they hit the doors, but that’s about it.
I am not against armored electric vehicles. If you need armored vehicles, you might as well make them electric.
However, this is certainly weird. Why does the State Department need $530 million worth of armored vehicles? And why is it listed under a bunch of unrelated categories that don’t make sense?
Sounds like a job for DOGE? However, Elon will need to recuse himself from that one, I guess.
