Apple has been subpoenaed by the Federal Trade Commission (FTC) for information on its deals with Google in relation to the use of the firm's search tool within its iPhone and iPad devices, according to Bloomberg.
Citing two people familiar with the matter, the report claims that the FTC has asked Apple for documents that will reveal the nature of the agreements between the two firms, as it investigates whether Google is abusing its dominance in the market.
Both Apple and Google had not responded to a request for comment when contacted by V3.
Several of Google's key rivals, including Microsoft, have filed complaints with both US and European regulators, citing their concerns with Google's market dominance, with the European Commission launching its own investigation into the firm last year.
Google executive chairman Eric Schmidt also appeared before members of the US Senate to answer questions relating to the firm's market dominance. At that time, he was forced to strongly deny suggestions the firm may have been "cooking the books" to improve the search rankings of its own services over those of rivals.
