Gmail, the free e-mail service run by internet search giant Google, will change its name for new UK users.
Following a trademark dispute the mail account will be renamed Googlemail.
London-based Independent International Investment Research says it started using the Gmail name for a web-mail application two years before Google.
Current UK users of Google's service will be unaffected, but a separate trademark dispute forced Google to drop the Gmail name in Germany in May.
Talks between both companies broke down several months ago, after they failed to agree a financial settlement.
