Nokia is fighting for 5G patent in court: Network slicing in focus!

Indien - In the past few days there have been considerable developments in the world of mobile phone technology, in particular with regard to 5G network slicing technology. Nokia Technologies, a subsidiary of the Finnish communications giant, submitted a lawsuit before the Delhi High Court. The reason? The Indian Patent Office has rejected the approval of an important patent for an "improved registration procedure". This patent is crucial for the support of network slicing in India, a concept that enables telecommunications companies to segment your network in different parts that can be used for different applications. This could be of great importance, for example, for companies that have special security requirements.

On July 17, 2025, judge Saurabh Banerjee expressed concerns about the application of Nokia in a message. The next hearing is already scheduled for November. In the meantime, the patent's lawyer has applied for a period of six weeks to submit an answer to the lawsuit. Nokia tries to contest the decision of the patent authority that the patent had rejected due to a lack of novelty.

Nokia's patent portfolio and the fight for 5G

It is interesting to note that Nokia makes remarkable progress in a different context: the company has now reached 7,000 patent families that are considered essential for 5G technology. These patents include key technologies for the interaction of smartphones and other devices with 5G networks. According to Nokia, all devices that connect to a mobile network can fall back on the patented technology of the company. This impressive number was announced on January 7, 2025 in Espoo.

The nokia core innovations in 5G technology cover areas such as the 5G radio protocol design, security and interface technologies. With over 150 billion euros that have been invested in research and development (R&D) since 2000, Nokia endeavors to assert its place at the head of mobile phone technology. Patrik Hammarén, Interim President of Nokia Technologies, underlined the relevance of these investments and the standardization efforts. More than 250 companies have already acquired licenses for Nokia's technologies, which forms the framework for a fair licensing system.

competition in the 5G sector: Ericsson is progressing

While Nokia is fighting with the legal challenges, the competition in the field of 5G technology remains highly competitive. Ericsson recently announced that it will expand his research and development in India, with a focus on network application programming interfaces (APIs), artificial intelligence (AI) and the basics for the upcoming 6G technology. The aim of this advance is to improve telecommunications capacities in various industries. Engineers for the locations in Chennai, Bengaluru and Gurugram are to be stopped in order to work with important service providers and to develop secure, simplified network interfaces.

This competitive pressure and continuous progress in technology illustrate how dynamic the industry is. Leading telecommunications providers such as Nokia, Ericsson, Huawei and Samsung have already developed commercial solutions for network slicing, and many large operators worldwide use these solutions actively or carry out tests. In the United States, in the United Kingdom, in Germany, Japan, South Korea, China and parts of Europe, there are already ongoing or pilot -style projects.

The coming months could be crucial, not only for Nokia in her legal dispute, but also for the entire industry that is developing quickly. Finally, the result of these patent disputes could have far -reaching effects on the future development of mobile phone technology, especially at a time, in which 5G is becoming increasingly important.
