ET went into administration in June after failed attempts to find a buyer.
TAP head of corporate development Harb Sangha said TAP had bought ETs intellectual property, including its company name, trademarks, brand names and web domains.
Sangha said: We will be adding to our large stable of companies and this will fit in very nicely. Although the company went into administration, European Telecom had a good name. Our executives are brainstorming for ideas on how this could widen the field for us. This will see us leapfrog a lot of other companies.
Sangha would not confirm rumours that TAP paid more than £500,000 for ETs naming rights
