Tesla Semi lawsuit drags on with small victory for Nikola Motor
Almost two years ago, Nikola Motors surprised the trucking market by filing a $2 billion lawsuit alleging that the Tesla Semi copied several design elements from the Nikola One, the truck-maker’s flagship hydrogen long hauler. News about the patent lawsuit has been scarce for over a year, but recent updates indicate that Nikola has snatched a small victory from the Silicon Valley-based electric car maker.
Nikola’s case listed several characteristics of the One that were allegedly copied by Tesla. These included the Semi’s wraparound windshield, mid-entry door, front fenders, and the all-electric truck’s aerodynamic shape. To highlight its point, Nikola stated that the similar drag coefficients between the One (0.37) and the Semi (0.36) was further proof that the battery electric long hauler was copied from the hydrogen fuel-cell sleeper cab.
Excerpts from Nikola’s lawsuit pointed out that the Semi’s design had caused confusion among the One’s customers, diverting sales from the hydrogen truck maker to Tesla. Nikola also argued that these confusions might result in the Semi’s problems being attributed to the One, such as those resulting from Tesla’s batteries and Autopilot software. These, according to Nikola, are causing damage to its brand.
“Tesla has had problems with its batteries starting fires and its autonomous features causing fatal accidents. Should these problems arise with the Tesla Semi, the market will attribute these problems to Nikola because of the similarities between the two vehicles. Customers will also impute the Tesla Semi’s limitations (distance and charging time) to Nikola, which will make Nikola’s product less appealing to customers,” the hydrogen truck maker noted in its complaint.
Unfortunately for Nikola, cases that are centered on design patents are very difficult to prove. This point was especially highlighted in August 2018 when the US Patent Office awarded Tesla a pair of design patents for the Semi that actually listed the Nikola One as a reference, which meant that the examiner deemed Tesla’s design as unique. For Nikola to win its case against Tesla, it would have to prove that the US Patent Examiner made a mistake when comparing the Semi and the One’s designs, and that’s a very difficult point to argue.
Yet if recent tweets from Nikola CEO Trevor Milton are any indication, it appears that the hydrogen truck maker has stood by its lawsuit against Tesla. As it turned out, Tesla had filed a request with the Patent Trial and Appeal Board in September 2019 asking for a review to invalidate Nikola’s side door patent for the One. This request seems to have failed. Granted, it is a very small victory for Nikola, considering that it is fighting an incredibly steep uphill battle. Still, the dismissal of Tesla’s effort is a victory for the hydrogen truck maker nonetheless.
“Tesla loses bid to invalidate @nikolamotor patents in USPTO dispute. USPTO not only upheld Nikola semi truck important patents but refused Tesla’s ask to modify our patents. Two billion-dollar lawsuit moving forward. We will defend our company’s IP no matter who it is,” Milton wrote on Twitter.
In a statement to Forbes, Nikola Chief Legal Officer Britton Worthen lauded the decision, stating that the development was “obviously favorable” and that the company believes the matter was “decided correctly.” Tesla, for its part, has declined to comment. That being said, a Tesla spokesperson has noted in the past that “It’s patently obvious there is no merit to this lawsuit.” Elon Musk does not seem to be bothered by the suit either, noting in a previous earnings call that the entire situation is a case of fate loving irony.
Ultimately, the Nikola One may very well be beaten to the market by the Tesla Semi. While the One was unveiled prior to Tesla’s all-electric truck, prototypes of the Semi have been conducting real-world testing since the vehicles were unveiled. Recent sightings of the all-electric trucks suggest that the vehicles are now being tested in harsh conditions. This hints that Tesla may actually be on track to start early production runs of the Semi sometime later this year, as hinted at by the company in the past. Nikola, for its part, seems to be on track to release the Nikola Two, a shorter-range, battery electric truck, before the One. The company expects to start production of its trucks next year.

Elon Musk teases expectations for Tesla’s AI6 self-driving chip
This optimistic timeline for tape-out—the stage where chip design is finalized before manufacturing—signals Tesla’s push to rapidly advance its silicon capabilities.
Tesla CEO Elon Musk is outlining expectations for the AI6 self-driving chip, which is still two generations away. Despite this, it is already in the plans of the company and its serial entrepreneur CEO, who has high expectations for it.
Musk provided fresh details on the company’s aggressive AI hardware roadmap, spotlighting the upcoming AI6 chip designed to supercharge Tesla’s self-driving tech, humanoid robots, and data center operations.
In a post on X dated March 19, Musk stated, “With some luck and acceleration using AI, we might be able to tape out AI6 in December.”

This optimistic timeline for tape-out—the stage where chip design is finalized before manufacturing—signals Tesla’s push to rapidly advance its silicon capabilities.
The announcement builds on progress with the predecessor AI5. Earlier in January, Musk announced that the AI5 design was “in good shape” and “almost done,” describing it as an “existential” project for the company that demanded his personal attention on weekends.
He characterized AI5 as roughly equivalent to Nvidia’s Hopper class performance in a single system-on-chip (SoC) and Blackwell-level as a dual configuration, but at significantly lower cost and power usage.

Musk highlighted that AI5 “will punch far above its weight” thanks to Tesla’s co-designed AI software and hardware stack, making maximal use of every circuit. While capable of data center training tasks, it is primarily optimized for edge computing in Optimus robots and Robotaxi vehicles.
For AI6, Musk envisions substantial gains. “In the same half reticle and same process node, we think a single AI6 chip has the potential to match a dual SoC AI5,” he explained.
The company is targeting ambitious nine-month development cycles for future chips, allowing rapid iteration to AI7, AI8, and beyond. AI5/AI6 engineering remains Musk’s top time allocation at Tesla, with the CEO calling AI5 “good” and AI6 “great.”
Samsung is expected to manufacture the AI6 chips, following deals worth billions, while AI5 will leverage TSMC and Samsung production. These chips will form the backbone of Tesla’s Full Self-Driving system, enabling safer and more capable autonomy, alongside powering dexterous movements in Optimus bots and efficient inference in expanding data centers.

Musk has also restarted work on the Dojo 3 supercomputer project now that AI5 is progressing. Long-term plans include in-house manufacturing via the Terafab facility.
By accelerating chip development with AI tools, Tesla aims to reduce dependence on third-party GPUs and deliver high-performance, energy-efficient solutions tailored to its ecosystem. Success with AI6 could mark a major milestone in Tesla’s journey toward full autonomy and robotics leadership, though timelines remain subject to manufacturing realities.

SpaceX is quietly becoming the U.S. Military’s only reliable rocket
Space Force drops ULA for SpaceX on GPS launch after Vulcan rocket anomaly investigation halts flights.
The U.S. Space Force announced today it is switching an upcoming GPS III satellite launch from United Launch Alliance’s Vulcan rocket to a SpaceX Falcon 9, a move that is as much a reflection of Vulcan’s mounting problems as it is a validation of SpaceX’s growing dominance in national security space launch. The GPS III Space Vehicle 09, originally contracted to fly on Vulcan this month, will now target a late April liftoff on Falcon 9, marking the fourth consecutive GPS III satellite the Space Force has moved to SpaceX after contracts were originally awarded to ULA.
The immediate trigger is a solid rocket motor anomaly that occurred on February 12 during Vulcan’s USSF-87 mission. Although the payloads reached orbit and ULA declared the mission successful, the company characterized the malfunction as a “significant performance anomaly” and has since paused all military launches on Vulcan pending a root cause investigation.
“With this change, we are answering the call for rapid delivery of advanced GPS capability while the Vulcan anomaly investigation continues,” said Systems Delta 81 Commander Col. Ryan Hiserote. “We are once again demonstrating our team’s flexibility and are fully committed to leverage all options available for responsive and reliable launch for the Nation.”
The broader reality is that SpaceX’s reliability record and launch cadence have made it the path of least resistance for the Pentagon, and bodes well with Elon Musk’s plans to IPO SpaceX sometime this year. Its Falcon 9 is the most flight-proven rocket in history, and the Space Force’s Rapid Response Trailblazer program was specifically designed to enable exactly this kind of provider swap for GPS missions, and effectively building SpaceX’s flexibility into the national security launch architecture by design.
For ULA, the stakes are existential. The company entered 2026 with aspirations of finally turning a corner after years of Vulcan delays, with interim CEO John Elbon pointing to a backlog of over 80 missions as reason for optimism. Meanwhile, SpaceX’s contracts with the Space Force have given it a formal pathway to take on even more national security launches going forward.
The significance of today’s announcement extends beyond one satellite swap. It reinforces that America’s most critical space infrastructure, including GPS, missile warning, and beyond, is increasingly dependent on a single commercial provider.

Tesla Full Self-Driving gets huge breakthrough on European expansion
All documentation for UN R-171 approval and Article 39 exemptions has been submitted, with RDW now conducting its internal review. Approval in the Netherlands is expected on April 10, shifted from the original March 20 target, following 18 months of rigorous collaboration.
Tesla Full Self-Driving has gotten a huge breakthrough as the company is still planning big things for its European expansion, hoping to bring the impressive platform into the continent after years of attempts.
Tesla Europe has announced a major breakthrough: the company has officially completed the final vehicle testing phase for Full Self-Driving (Supervised) in partnership with the Dutch vehicle authority RDW.
All documentation for UN R-171 approval and Article 39 exemptions has been submitted, with RDW now conducting its internal review. Approval in the Netherlands is expected on April 10, shifted from the original March 20 target, following 18 months of rigorous collaboration.
Together with RDW, we have officially completed the final vehicle testing phase for Full Self-Driving (Supervised) and have submitted all documentation required for the UN R-171 approval + Article 39 exemptions. The RDW team is now reviewing the documentation and test results…
— Tesla Europe, Middle East & Africa (@teslaeurope) March 20, 2026
The process has been exhaustive. Tesla said it has logged more than 1.6 million kilometers of FSD (Supervised) testing on European roads, conducted over 13,000 customer ride-alongs, executed 4,500+ track test scenarios, produced thousands of pages of documentation covering 400+ compliance requirements, and completed dozens of independent safety studies.
The company expressed pride in the partnership and anticipation of bringing the feature to “patient EU customers” soon after approval.
Europe’s regulatory landscape has presented steep challenges for Tesla’s advanced driver-assistance systems. The EU enforces some of the world’s strictest safety standards under the United Nations Economic Commission for Europe framework, particularly UN Regulation 171 on Driver Control Assistance Systems.
Unlike the more permissive U.S. environment, European rules historically limited system-initiated maneuvers, required constant driver supervision, and demanded country-by-country or bloc-wide exemptions. Tesla faced repeated delays, with initial February 2026 targets pushed back amid RDW’s insistence that safety, not public or corporate pressure, would govern timelines.
Tesla Europe builds momentum with expanding FSD demos and regional launches
A former Tesla executive warned in 2024 that certain regulatory elements could slip to 2028, highlighting bureaucratic hurdles, extensive audits, and the need for harmonized data privacy and liability frameworks across fragmented member states.
Yet progress is accelerating. Amendments to UN R-171 adopted in 2025 now permit hands-free highway lane changes and other automated features, clearing technical barriers. Once the Netherlands grants national approval, mutual recognition allows other EU countries to adopt it immediately, potentially leading to an EU-wide rollout by summer 2026.
This European breakthrough is part of Tesla’s broader push into foreign markets. Full Self-Driving (Supervised) is already live in the United States and expanding rapidly.
In China, where partial approvals exist, CEO Elon Musk has targeted full rollout around the same February–March 2026 window, despite lingering data-security reviews.
Additional markets, including the UAE, are slated for early 2026 launches. These expansions are critical as Tesla seeks to monetize software amid softening EV demand globally.
For European Tesla owners, the wait appears nearly over. Approval would unlock advanced autonomy features that have long been available elsewhere, marking a pivotal step in Tesla’s global autonomy ambitions and reinforcing its commitment to navigating complex international regulations.
