Supporters of Lojban use the term Loglan as a generic term to refer to both their own language and Brown's Loglan, referred to as "TLI Loglan" when in need of disambiguation. Although the non-trademarkability of the term Loglan was eventually upheld by the United States Patent and Trademark Office, many supporters and members of The Loglan Institute find this usage offensive and reserve Loglan for the TLI version of the language.
