A "specimen" is an actual example of use of the mark in the stream of commerce. It is the means by which a consumer would view your mark and be aware of the specific goods or services offered.

For a trademark, an acceptable specimen would be the actual label or packaging used on the product which is sold under the mark.

For a service mark, an acceptable specimen would be an advertisement, such as a newspaper ad, brochure, leaflet or flyer which shows the mark and denotes the services provided to the public and distinguishes the services from those of another party.
