I
dentication or Status
To consistently identify trademarks and ser-
vice marks, a (mostly) international system of
demarcation or trademark notices has been
established.
In most countries, the
TM
symbol is recognized
as identifying an unregistered trademark. The
SM
symbol is used to identify an unregistered
service mark (a mark used in connection with a
company’s services rather than with goods). Al-
though these symbols have no legal signicance,
their use does have the preventative effect of
indicating possible claims to trademark rights in
the designations with which they are used.
Most countries have also adopted the ® symbol
to identify a registered trademark or service
mark. Other proper forms of notice for registered
trademarks in the U.S. include: “Registered
in the U.S. Patent and Trademark Ofce” and
“Reg. U.S. Pat. & Tm. Off.” Certain countries
have other symbols and designations, including
“Marca Registrada” or “MR” in some countries
where Spanish is the dominant language, and
“Marque Déposée,” “Marque de Commerce,”
or their abbreviations, “MD” and “MC,” in some
countries where French is the dominant lan-
guage. Demarcation practices vary from country
to country and, logically, marking should be in
the local language(s) or otherwise meaningful
to your readers and/or the people in the country
in which the products or services are advertised
and sold.
