Dear minarah,

The U.S. Patent and Trademark Office issued the patent for the
antiviral combination of the two active ingredients lamivudine and
zidovudine, branded as "Combivir", on 12 January 1999. The patent
number is 5,859,021.

The U.S. trademark "Combivir" for that drug was applied for by Glaxo
Group Limited on 20 February 1997 and registered by the Trademark
Office on 19 May 1998.

Combivir was launched in the USA on 26 September 1997.

Hope this answers your question!
