Kharkiv IT company Nix continues to sue Lviv-based N-iX over the similarity of their names. Now Nix wants to use the court to prohibit one of the Lviv company's legal entities from using the name N-iX. If the court grants the lawsuit, this legal entity may have to change its name.
Kharkiv IT company Nix continues to sue Lviv-based N-iX over the similarity of their names. Now Nix wants to use the court to prohibit one of the Lviv company's legal entities from using the name N-iX. If the court grants the lawsuit, this legal entity may have to change its name.
This is reported by Forbes Ukraine.
Nix's new lawsuit concerns N-iX Delivery LLC, one of the companies in the Lviv-based N-iX group. The court took up the case back in August 2026, and the next preparatory hearing is scheduled for December 1. Nix insists that the competitor's name is easily confused with their trademark.
N-iX is not going to give in. The Lviv company reported that they are confident in their legal position and are considering all legal means of defense, but refused to comment on the conflict in more detail.
Even if the court sides with the Kharkiv residents, the entire N-iX group will not have to urgently look for a new name. As lawyers interviewed by Forbes Ukraine explain, the decision will only apply to N-iX Delivery LLC. After all, to prohibit other companies in the group from using the name, Nix will have to sue each of them separately.
But for N-X Delivery, the consequences could be more tangible. Depending on the court's decision, it could be banned from using the name in advertising, on its website, or even in its domain name. The main risks are additional costs for renaming and possible reputational damage.
The dispute has been going on since 2021, when Nix began challenging the registration of the N-iX trademark. In April 2025, the Kharkiv-based company went to court to have N-iX’s certificate for the “NX” trademark revoked. The case is still ongoing. The next hearing is scheduled for November 18.
In October 2026, Nix announced a partial victory in another dispute. According to it, the Appellate Chamber of the Ukrainian IP Office partially canceled the registration of the N-iX trademark. So, Lviv residents allegedly lost the opportunity to register it for programming and other IT services. However, the IP Office explained to Forbes Ukraine that this process is ongoing.
One of Nix's main arguments is that the company appeared earlier. The Kharkiv-based company has been operating since 1994, while N-iX has been around since 2002. But the court will also look at when exactly the companies involved in the case started using their names.
Also, both companies develop software, so customers could theoretically confuse them. This is an argument in favor of Nix. However, the brands have coexisted in the same market for more than 20 years. And if N-iX can prove that there was no confusion during that time, this could help it in court.
Lviv-based N-iX is trying to cancel the registration of the Kharkiv-based Nix trademark, which operates in the European Union. It claims that the word Nix is not unique enough, because it is also the name of a package manager and a programming language. In November 2025, the EU Intellectual Property Office rejected N-iX's claim, but the company filed an appeal.
Previously, dev.ua wrote that Lviv-based N-iX tried to reach an agreement with Kharkiv-based Nix on the coexistence of brands, but the parties never reached an agreement. N-iX then stated that their name differs from the competitor's brand both visually and in sound.
