Archer Aviation Secures Key eVTOL Technology in Strategic Patent Acquisition from Lilium

The advanced air mobility (AAM) sector is undergoing a significant phase of consolidation, and intellectual property is proving to be the new currency. In a move that underscores this trend, U.S.-based Archer Aviation has successfully acquired the extensive patent portfolio of German eVTOL pioneer Lilium GmbH. Announced at the National Business Aviation Association (NBAA) 2025 convention, this acquisition marks a pivotal moment for Archer, substantially enhancing its technological arsenal and solidifying its position in the highly competitive electric aviation landscape.

The transaction saw Archer win a competitive bidding process to obtain approximately 300 of Lilium’s patent assets for €18 million. This portfolio is the culmination of nearly a decade of research and an investment reported to be over $1.5 billion by Lilium, a company once seen as a frontrunner in the eVTOL space. For Archer, this is more than just an expansion of its intellectual property; it’s a strategic absorption of cutting-edge innovations that could shape the future of its aircraft development and the broader AAM market. The move is also framed as a step to ensure U.S. leadership in a critical emerging technology sector, especially following the recent acquisition of another eVTOL company, Volocopter, by a Chinese buyer.

Bolstering a Technological Arsenal

The acquisition significantly expands Archer’s intellectual property holdings, bringing its total to over 1,000 patent assets worldwide. The acquired portfolio is not just vast but also diverse, covering a wide spectrum of technologies crucial for eVTOL aircraft. These innovations include ducted fans, advanced propeller systems, high-voltage systems, sophisticated battery management, and foundational elements of aircraft design, flight controls, and electric engines. This infusion of technology provides Archer with a powerful toolkit to enhance its current and future aircraft platforms.

Among the acquired assets, Lilium’s work on ducted fan technology is considered particularly valuable. Many in the industry believe it to be the world’s leading patent portfolio on the subject. This technology could be instrumental for Archer’s future development roadmap, potentially unlocking new capabilities in both the light-sport and regional air mobility sectors. The timing aligns with regulatory advancements, such as the U.S. Department of Transportation and FAA‘s modernization of the special airworthiness certification (MOSAIC) final rule in July 2025, which is designed to foster innovation in this very space.

Adam Goldstein, Archer’s founder and CEO, highlighted the significance of the deal, stating, “Lilium’s pioneering work advanced the frontier of eVTOL design and technology, and we’re excited to bring their cutting-edge technologies into the fold at Archer as we advance our product roadmap.” This sentiment reflects a broader industry acknowledgment of Lilium’s technological prowess, even as the company faced financial headwinds. The acquisition allows Archer to build upon a foundation that was, by many accounts, technologically ahead of its time.

Through this purchase, Archer gains key enabling technologies that bolster its current platforms, including what is believed to be the leading patent portfolio on ducted fan technology in the world.

A Landscape of Consolidation and Competition

The acquisition of Lilium’s patents did not happen in a vacuum. It is a clear indicator of a maturing industry where early innovators are either scaling up or being absorbed by better-capitalized competitors. Lilium, founded in 2015, faced significant financial challenges leading up to this point, including difficulties in securing financing that ultimately led to insolvency. The competitive bidding process for its intellectual property reportedly involved another major player, Joby Aviation, highlighting the perceived value of Lilium’s technological contributions.

This transaction is part of a larger narrative of consolidation within the AAM sector. As companies move from design and prototyping to the incredibly capital-intensive phases of certification and manufacturing, financial strength becomes paramount. Weaker players, despite their technological innovations, are becoming acquisition targets. Archer’s move positions it as a consolidator, strategically leveraging its resources to acquire valuable assets at a fraction of their original development cost.

By securing these patents, Archer not only enhances its own capabilities but also creates a higher barrier to entry for new competitors. Intellectual property is a critical moat in a field where differentiation is key. This strategic acquisition ensures that a significant body of pioneering eVTOL research remains under U.S. stewardship, a point Archer has emphasized. It strengthens the company’s competitive position against both domestic rivals and international players in the global race to define the future of urban and regional air travel.

Conclusion: The Path Forward

Archer Aviation’s acquisition of Lilium’s patent portfolio is a calculated and strategic move that reverberates through the advanced air mobility industry. For a relatively modest investment of €18 million, Archer has incorporated over a billion dollars’ worth of research and development into its own strategic roadmap. This not only accelerates its own innovation timeline but also reinforces its standing as a leader in the eVTOL space. The deal is a testament to the idea that in a pioneering industry, technological assets are as crucial as manufacturing capabilities.

Looking ahead, the integration of Lilium’s technologies, particularly in ducted fans and battery management, could unlock new performance efficiencies and design possibilities for Archer’s future aircraft. As the AAM sector continues to consolidate, the ability to strategically acquire and leverage intellectual property will be a defining characteristic of the companies that ultimately succeed. This acquisition is a clear signal that the race to commercialize eVTOLs is entering a new, more mature phase, where strategic asset accumulation is key to long-term viability and market leadership.

Vertical Aerospace has received AS9100 certification for the quality management system that covers its design and production work, and the Bristol-based developer of the Valo electric vertical take-off and landing (eVTOL) aircraft believes it is the first eVTOL developer to achieve the standard. The British Standards Institution (BSI) awarded the certificate after an independent assessment that closed a year-long quality improvement programme at the company.

In a press release dated November 12, 2026, and announced on World Quality Day, Vertical said the certification confirms that its quality management system across design and production meets the standards used by manufacturers such as Airbus and Boeing. The company said it gives airline customers and operating partners independent assurance about its future aircraft production and delivery, and supports opportunities where AS9100 is required. The certificate comes as Vertical prepares to build its first certification-conforming aircraft, and after it announced a review of strategic alternatives on September 24, 2026.

What the AS9100 standard covers

AS9100 was developed by the International Aerospace Quality Group (IAQG) and builds on ISO 9001 with requirements for aviation, space and defence. The IAQG states that the standard can be used “at all levels of the supply chain by organizations around the world,” and that it is intended to improve quality, schedule and cost performance by reducing or eliminating organisation-unique requirements.

For Vertical, the certificate is the result of a year-long quality improvement programme that ended with BSI’s independent assessment. Stuart Simpson, chief executive of Vertical Aerospace, said:

“We are leading the way in electric aviation by holding ourselves to the highest standards in aerospace.”

Simpson said achieving AS9100 means the company’s quality management system is certified against the same standard used by established manufacturers such as Airbus and Boeing. “It is what our customers expect,” he said, adding that this is the discipline Vertical is bringing to Valo and to building a company customers can depend on.

Giancarlo Silvestri, Global Head of Aerospace and Defence (Assurance) at BSI, called the accredited certification “an important step in Vertical’s development as an aerospace manufacturer,” and said it gives airline customers and operating partners greater confidence in the quality management foundations behind the company’s ambitions.

A quality certificate alongside the regulator’s approvals

The AS9100 certificate comes from BSI. Vertical’s design organisation approval comes from the UK Civil Aviation Authority (CAA). In its release of March 30, 2023, Vertical said the CAA had issued it a Design Organisation Approval (DOA), number UK.21J.1001, the first DOA the CAA had issued to an eVTOL manufacturer. The CAA’s assessment for that approval covered Vertical’s procedures, quality management system, technical workforce competence, and facilities and equipment.

The same release said UK and European companies need a DOA to hold a Type Certificate, which Vertical described in July 2024 as a prerequisite for commercial service. On July 10, 2024, the company said the CAA had expanded the scope of the approval so that its own engineers could certify compliance in more technical areas, including further flight control, avionics and electrical systems activities. That release also said the European Union Aviation Safety Agency (EASA) and the CAA had agreed how they would collaborate on certification, setting up common standards and concurrent certification and validation of the VX4. Vertical unveiled Valo, which succeeds the VX4 prototype, on December 10, 2025.

Where the Valo programme stands

Valo is a piloted, four-passenger eVTOL whose cabin can expand to six seats, according to the December 2025 launch release, which gave a range of up to 100 miles at speeds of up to 150 mph. That release targeted certification in 2028, working with the CAA and EASA, and planned seven certification aircraft built in the UK.

The company’s more recent statements give 2029. In a release dated September 25, 2026, announcing the opening of its Aircraft Assembly Centre at Cotswold Airport, Vertical said the £1.5 million facility would build certification-conforming aircraft for compliance and verification testing with the CAA, targeting Type Certification in 2029. Assembly of the first certification-conforming aircraft is expected to begin in the fourth quarter of 2027.

After certification, the centre is expected to support initial customer deliveries, with capacity to assemble more than 25 Valo aircraft a year in the early-production phase. Higher-volume manufacturing will take place at a separate facility, and Vertical said it expected to announce plans for it in the fourth quarter of 2026.

In flight testing, Vertical said in its H1 2026 business update that in April it became the second company globally to complete a piloted transition flight in a full-scale tiltrotor eVTOL, and that it flew five consecutive days of piloted transition demonstrations at the Farnborough International Airshow in front of more than 140,000 visitors. The company has said it remains on track to complete its Critical Design Review by year-end 2026. On October 16, 2026, it announced supplier agreements for seating and inertial reference systems with ANH Structure and Northrop Grumman LITEF.

Financing, customers and the strategic review

On September 24, 2026, Vertical announced a review of strategic alternatives, including potential strategic and financial partnerships, and retained Jefferies LLC as financial advisor. It said operations, the certification programme and commercial commitments would continue during the review, that no timetable had been set, and that there was no assurance the review would result in any transaction or outcome. The company said it would not disclose developments unless its board approves a specific course of action, decides further disclosure is appropriate, or disclosure is required by law.

That announcement followed approximately $100 million of new financing and the appointment of former Airbus Commercial Aircraft chief executive Fabrice Brégier as chair. In its H1 2026 business update, Vertical reported cash and cash equivalents of approximately $134 million (£99 million) as of August 13, 2026, and expected net cash outflows of approximately $150 million (£110 million) over the following 12 months. It said short-term liquidity, remaining financing proceeds and anticipated future draws were expected to provide at least 12 months of runway.

Vertical reports about 1,500 pre-orders for Valo from customers on four continents, including American Airlines, Avolon, Bristow, GOL and Japan Airlines, and says certain customer obligations are expected to be fulfilled through third-party agreements. The company, headquartered in Bristol, UK, works with Honeywell, Syensqo and Sonaca and develops its own battery and propeller technology.

Archer Aviation and Formula 1 have announced a multi-year partnership to explore flying VIPs and fans to and from Grand Prix circuits aboard Archer’s Midnight electric air taxi, including dedicated landing points at circuits and air taxi services within F1’s hospitality and ticketing offerings.

Archer announced the agreement in a press release dated November 12, 2026. The partnership covers select Grands Prix that align with what Archer calls key commercial markets in the US, the Middle East, Asia and Europe. The release gives no financial terms and no date for a first air taxi flight at a race, and it describes the work as something the partners will explore.

What the partners plan to study

According to the release, the two companies will look at dedicated air taxi drop-off and pick-up locations at circuits, and at including air taxi services in F1’s hospitality and ticketing offerings. Once Archer’s commercial electric vertical takeoff and landing (eVTOL) operations launch in F1 markets, fans could skip traffic between major airports, business hubs and other key destinations, Archer said.

Emily Prazer, Chief Commercial Officer of Formula 1, said in the release:

“Innovation is at the heart of Formula 1, and Archer shares our passion for pushing boundaries and exploring what is possible.”

Adam Goldstein, Archer’s founder and CEO, pointed to the size of the sport’s audience, saying “With 830 million fans worldwide, Formula 1 gives us a global audience of prospective passengers”. He added that motorsport and aerospace share the same engineering DNA, and that the companies hope to show how innovation on the ground and in the sky could combine for fans at the track.

Archer also drew a technical comparison. It said the power-to-weight demands of eVTOL aircraft are comparable to those of F1, and that, as in an F1 car, its electric propulsion, advanced composites and aerodynamics are engineered as one system.

Where Archer’s planned networks meet the race calendar

Archer said its planned US air taxi networks map closely to F1 race locations, including Miami and Texas, where it has unveiled planned infrastructure networks. Its Texas plan, announced on October 23, 2026, includes an Austin network connecting Austin-Bergstrom International Airport and Austin Executive Airport with the F1 Circuit Helipad at the Circuit of the Americas, which Archer said would put Formula 1 United States Grand Prix races minutes away. The same plan covers Dallas-Fort Worth and Houston, and Archer said Midnight could turn 60 to 90 minute ground trips into 10 to 20 minute flights.

In South Florida, Archer’s Miami network plan of December 2025 named Hard Rock Stadium, home of the Formula 1 Crypto.com Miami Grand Prix, among the sites whose existing helipads will be prepared for electric operations. That network would also link Miami International Airport (MIA), Fort Lauderdale-Hollywood International Airport (FLL) and Palm Beach International Airport (PBI).

The partnership already has a public side. Archer displayed Midnight at the Formula 1 United States Grand Prix in Austin, October 22 to 25, in the Fan Zone and F1 Paddock as an Official Supporter of F1, and the aircraft will be displayed again at the Las Vegas Grand Prix and the Abu Dhabi Grand Prix later in 2026, according to the release. Archer’s third-quarter results release of November 9, 2026, had already said the two companies were forming a multi-year strategic alliance.

Where Midnight stands

Midnight is a piloted electric air taxi that carries up to four passengers and has 12 total engines and propellers, according to Archer. In its third-quarter update and FAA certificate news, Archer said Midnight had received a Market Survey Special Airworthiness Certificate from the FAA, which the company expects to allow operations in Los Angeles. The company said it is preparing to carry passengers under the US Department of Transportation’s eVTOL Integration Pilot Program (eIPP) and for the LA28 Olympic Games.

The eIPP is the framework for Archer’s planned Texas and Florida operations. In March 2026, the Department of Transportation and the FAA selected Archer’s partners in Texas, Florida and New York for the program, and Archer said at the time that it planned early Midnight operations in those states as soon as the second half of 2026. Archer, BETA and Macquarie Capital also launched the ACES charging consortium, which aims to electrify up to 250 air taxi sites across America by 2030 and is working with the Texas Department of Transportation on charging to support eIPP operations in Texas.

Archer reported third-quarter 2026 revenue of $5.1 million and a net loss of $274.6 million, with total liquidity of $1.4 billion. The company said its acquisition of Boeing’s Wisk, Insitu and SkyGrid businesses is nearing close, subject to certain regulatory approvals and other closing conditions.

What the announcement leaves open

The release names no race where air taxi transfers would be offered first, and gives no pricing or start date. It ties services for fans to the launch of Archer’s commercial eVTOL operations in F1 markets.

Archer’s forward-looking statements list aircraft design and specifications, development and certification timing, air taxi network plans including the eIPP, and the expected benefits of collaborations such as the one with Formula 1 among the matters that could differ from its plans.

Eve Air Mobility’s Vector software managed landing and takeoff slots at the temporary helipad serving São Paulo’s Interlagos Circuit during the motorsport weekend there, with traffic peaking at more than 100 helicopter flights on Sunday, November 8, 2026. Revo, the São Paulo helicopter operator that Eve calls its first electric Vertical Takeoff and Landing (eVTOL) aircraft customer, ran the system at the event for the second year in a row.

In a press release distributed on November 13, 2026, Eve, an Embraer Group company, said Revo’s team used Vector at the helipad set up at the Ayrton Senna Kart Track, next to the circuit, for scheduling and slot management of landings and takeoffs. Eve described the event as the largest international motorsport event, and said the software had been tested at the same event in 2025.

What Vector did at Interlagos

Vector is Eve’s urban air traffic management software. According to the release, it is built on a modular architecture, with Helipad and Vertiport (Aerodrome) and Ground Operations modules that let operators manage high-volume activity across vertiports and helipads. Eve said the software is designed to provide safe and efficient low-altitude air traffic management through automation and data-driven services, and said it represents a new step toward automated, scalable traffic management for Advanced Air Mobility (AAM) in Brazil and worldwide.

Eve said its team supported Revo’s operational staff throughout the weekend so that operations ran smoothly, effectively and “100% safely” across all three days of the event. The release does not give a total number of flights for the weekend or the number of helicopters involved; the only traffic figure is the peak of more than 100 flights on the Sunday.

Johann Bordais, chief executive of Eve Air Mobility, tied the result to the weekend’s traffic:

“The efficient use of Vector over a weekend that concentrates one of the highest volumes of helicopter traffic in Brazil throughout the year demonstrates the full maturity of our solutions for the urban mobility ecosystem.”

Bordais added that Revo will be Eve’s first eVTOL customer in Brazil and globally. João Welsh, chief executive of Revo, said the partnership with Eve “represents a major step in this direction,” both for bringing eVTOLs into Revo’s operations and for developing urban air traffic management solutions.

How the 2026 deployment compares with 2025

This was not Vector’s first outing at the circuit. On November 10, 2025, Eve announced the software’s first real-world deployment, with Revo, during the 2025 São Paulo Grand Prix. Revo’s team used Vector from November 7 to 9 that year to manage helicopter operations at the Interlagos racetrack, after training by Eve’s TechCare and Vector teams. Eve said at the time that future Vector operations were planned at other sites, including residential and commercial hubs.

The product description has moved since then. In November 2025, Eve listed a Vertiport and Ground Operations Module and said a Fleet Operations Module for helicopter and eVTOL operators was planned for 2026. The November 2026 release lists separate Helipad and Vertiport (Aerodrome) and Ground Operations modules and gives 2027 for the Fleet Operations Module. The release does not explain the change in timing. Eve says the fleet module will address the needs of helicopter and eVTOL operators as Urban Air Mobility networks expand.

The Revo contract behind the partnership

Revo is part of Omni Helicopters International (OHI), which, according to the November 2026 release, manages a fleet of approximately 90 helicopters and operates over 1,500 weekly flights. In a release dated June 15, 2025, Eve announced its first binding framework agreement with Revo and OHI, covering up to 50 eVTOLs, entry-into-service support and aftermarket services, including Eve’s TechCare package. Eve’s release for that deal was headed as a $250M contract, and the earlier work between the companies had included simulations of urban air traffic management using Vector.

The June 2025 release named Revo as launch operator for Eve’s eVTOLs in São Paulo, with first delivery planned for Q4 2027, and said the city has over 400 registered helicopters and nearly 2,000 daily takeoffs and landings. The November 2026 release says Revo is positioned to operate the technology in Brazil starting in 2028.

Where Eve’s eVTOL program stands

Eve reports a backlog of over 2,700 aircraft, including firm orders and letters of intent, across 28 customers in 10 countries. It has completed more than 73 flights since its flight test campaign began in 2025, after more than 10,000 hours of integrated ground testing. On August 3, 2026, Eve announced its first partial transition flight, in which the prototype’s rear pusher propeller was activated in the air for the first time and the aircraft reached a stabilized speed of 27 knots.

Eve plans to build six certification prototypes for a certification campaign starting in 2027, working with Brazil’s National Civil Aviation Agency (ANAC) and the FAA. Once the aircraft is certified, and through the end of 2028, it will be built at a facility under development in Taubaté, São Paulo, with initial capacity of up to 120 aircraft per year and room to expand to up to 480 aircraft annually.
