Proper Use of Trademarks

Use the ® to indicate AP Technology's fully registered trademarks and the TM to indicate our claimed trademarks. Please make the trademark symbol a superscript (® or TM) and position it immediately after the trademark to which it applies (e.g. AP Technology® SecureCheck® MICR Check Printing System).

The TM or ® designation is needed only for the first reference to a trademark in a document, unless you are citing or listing a series of product titles. In that case, the trademark symbols should be used with each name. Additionally, in publications consisting of several articles or chapters, use the TM or ® designation with the first instance of the trademark in each article or chapter.

At the end of publications, include one trademark paragraph that lists all applicable trademarks used in the publication. Do not include the actual TM or ® symbols in the trademark paragraph.
