Use the appropriate trademark symbol and trademark acknowledgment of O2Micro's
ownership of the marks and/or logos in question.
Do not incorporate O2Micro trademarks or logos into your own product names, service

To ensure trademarks and logos are consistently used worldwide, all internal and external
communications, documents and electronic messages must be reviewed and approved by

Trademarks should be used as Adjectives
Trademarks are adjectives and should be followed by approved nouns. Because trademarks are
not nouns, they should never be pluralized, and they should never be used in the possessiveform.
