The mark should be on the first use of the paper, even though the symbol may have already been used in the headline or other prominent use.

Annual and Quarterly Reports
The mark should appear on the first or most prominent use of each trademark on each page and there should be a trademark legend. See below on how to use the trademark legend.

To attribute ownership of a trademark:

• You may insert the superscript trademark symbol immediately after the actual trademark. If ™ or ® are unavailable, you may use the appropriate parenthetical trademark designation: (TM) or (R).
• You may insert a trademark legend. The legend is usually found at the end of the document (minimum 8 point font) following the copyright notice.

Affymetrix trademarks present in text should be attributed with an appropriate trademark legend.

The legend should be in at least eight point size. Generally, it appears at the end of a document or on the back of a package, but it may be placed elsewhere if appropriate.

Examples of standard legend language are:

GeneChip is a registered trademark of Affymetrix, Inc. NetAffx is a trademark of Affymetrix, Inc.
