ARLANXEO has announced that the German Federal Patent Court has nullified the German component of European patent EP 3 800 714. The contested intellectual property, held by Zeon Corporation, pertains to synthetic rubber compounds utilised as cathode binders within rechargeable battery systems, a sector critically linked to electric vehicles and energy storage solutions.

The revocation stems from an ongoing legal confrontation regarding battery binder technology. Zeon initiated infringement lawsuits in 2024 against ARLANXEO’s German and Dutch operations at the Munich Regional Court. In response, ARLANXEO contested the patent's legal standing, prompting a validity review by the Federal Patent Court.

Following a preliminary July 2025 ruling that cast substantial uncertainty on the patent’s enforceability, the Munich court suspended the infringement case. With the formal revocation in Germany, the foundational grounds for the local infringement allegations have been effectively eliminated.

John Gerrese, General Counsel, ARLANXEO, said, “We welcome the Court’s decision, which confirms our position on the invalidity of the patent. The ruling underscores the importance of robust patent standards. It also highlights the critical role of nullity proceedings in ensuring that only valid and enforceable patents are upheld.”

Hankook Tire held its 2026 Design Innovation Day on 30 October at Hankook Technodome, the company’s advanced research and development centre in Yuseong-gu, Daejeon, South Korea. The event, themed ‘Shaping Identity, Sculpting Performance’, gave employees a chance to learn about the tyre maker’s design strategies and major accomplishments.

A central highlight was the company’s first public presentation of a unified product design identity framework covering its principal brands: iON, the world’s first full-lineup tyre brand dedicated to electric vehicles; Ventus, its flagship line and Dynapro, its SUV-focused brand. Hankook Tire also introduced a next-generation product design language for the first time and explained how it will be applied to future products, clarifying each brand’s design direction and creating a consistent approach across the portfolio.

The programme featured three sessions. One addressed design strategies for conveying product performance while preserving brand identity and introduced guidelines for turning ‘invisible performance’ developed during R&D into design elements consumers can recognise, with approaches tailored to different product characteristics. Another session presented the next-generation design language for iON, Ventus and Dynapro, translating each brand’s core values into distinctive design elements. Hankook Tire further shared a framework for collaboration among R&D, product planning, marketing and design teams so they can develop products under unified design standards.

Through the event, Hankook Tire seeks to align design strategies and direction across the organisation, improve product development efficiency and speed decision-making while strengthening global brand recognition and its premium image. The company also aims to bolster design competitiveness in original equipment collaborations with global automakers and in product development for global markets. Hankook Tire continues to earn international design recognition, including three Product Design awards at the 2026 Red Dot Design Awards for Ventus evo, iON AT and Laufenn S FIT2, plus six Design Concept awards comprising two Best of the Best honours and four Red Dot awards.

Lassa Tyres has introduced the Wintus 3, a new winter tyre engineered for light commercial vehicle operators who depend on reliable, durable performance in harsh cold-weather conditions. The company designed the pattern to address the varied demands of business users whose vehicles are central to their operations.

The Wintus 3 features a new-generation tread pattern, advanced construction and innovative compound technologies, delivering gains over its predecessor that include up to 60 percent longer wear life and a 27 percent reduction in rolling resistance for improved efficiency and more sustainable mobility. It also improves wet braking, snow and ice performance, wet handling and dry braking.

The tyre carries the TÜV SÜD Performance Mark, with independent benchmark testing showing measurable advantages over the competitor average in snow acceleration, snow braking, wet braking, wet cornering, dry braking and fuel and energy efficiency, including improvements exceeding 10 percent in dry braking, wet braking and fuel efficiency.

Offered in 22 sizes spanning 14 to 16 inches, the Wintus 3 will be available in Lassa markets during the 2026 winter season, with size availability varying by market.

Liberty Tire Recycling has published the industry’s first US company-commissioned lifecycle assessment (LCA) centred on rubber-modified asphalt solutions made from recycled tyres. The study was commissioned by Liberty and carried out by Boundless, applying internationally recognised LCA methodology to evaluate the environmental impacts of the company’s asphalt-related products against conventional alternatives used in asphalt modification.

The company described the assessment as a notable step forward for rubber-modified asphalt. Environmental gains are routinely linked to recycled tyre materials in road building, yet Liberty said this analysis supplies quantified evidence behind such assertions. Greenhouse gas emissions tied to its rubber-modified asphalt solutions were tracked throughout their lifecycle.

Results showed that Liberty's asphalt products carried substantially lower greenhouse gas impacts than conventional SBS polymer modifiers. Recovering and reusing end-of-life tyre materials was also found to deliver environmental benefits exceeding the impacts of processing them. Liberty said the findings give transportation agencies, engineers, contractors and infrastructure stakeholders data-driven insights for choosing materials.

Four products were assessed: crumb rubber and three asphalt additives, namely dry mix rubber additives, a DOT additive and combined micronised rubber powder with the Rheopave additive. Dry mix rubber additives yielded the largest carbon benefit, avoiding up to 0.577 kg CO₂e per pound produced, while the tyre-derived products achieved over 100 percent lower greenhouse gas footprint than traditional SBS modifiers. Each product assessed generated a net environmental benefit, with reductions spanning 0.47 to 0.57 kg of CO₂e per pound.

Liberty said the study helps set a benchmark for measuring and communicating environmental impacts as sustainability gains prominence in infrastructure projects, and that transparent, science-based data will matter increasingly to public agencies and industry leaders weighing performance and environmental goals.

Avon Tyres will make its second consecutive EICMA appearance this year, using the Milan show to unveil a refreshed motorcycle range and a renewed brand identity to a global audience of riders and trade visitors. The company will occupy Hall 9, Booth U65 at Fiera Milano between 3 and 8 November.

The exhibit reflects Avon's ‘made to be different’ philosophy and presents a focused portfolio spanning sport, touring, adventure, cruiser and classic segments. Avon's return also signals progress within Goodyear's motorcycle portfolio, where, since joining the family of brands in 2022, it has paired longstanding heritage with a modern product strategy and upgraded manufacturing.

Four flagship tyres anchor the display: the Spirit ST for sport-touring, the 3D Supersport for hypersport riders, the Roadrider MKII for classics and the Cobra Chrome for cruiser, touring and custom applications, the latter now offered in additional sizes. They are joined by the Trailrider 2, a new adventure-touring tyre launching in January 2027 that carries the ‘made to blaze your own trail’ message, targets an 80:20 road-to-off-road mix and will come in at least 20 sizes for popular adventure bikes.

Together with the existing Trekrider and Streetrunner, the lineup forms Avon's most comprehensive public display of its motorcycle portfolio to date. EICMA, which drew over 600,000 visitors last year including nearly 43,000 trade professionals from 167 countries, gives the brand a truly global stage for engaging riders, dealers and partners. Public-day attendees can also meet stunt rider Rok Bagoros at the stand on Friday 6 November at 11:30.

Roberto Finetti, Marketing Manager Motorcycle Europe, Goodyear, said, “We’re looking forward to speaking with riders and partners at EICMA about our continued growth plans for Avon. EICMA is the world’s largest motorcycle exhibition and provides the ideal place to showcase our refreshed identity and tyre range under the ‘made to be different’ philosophy.”
