Try to avoid using trademarks whenever possible. When trademarks do need to be used, remember to follow standard English text formatting and capitalization rules even if the trademark owner encourages special treatment. Do not use special symbols such as TM and ® unless they are important to the context, such as to distinguish between generic and brand names for drugs. Product logos and corporate logos may be used once in the infobox or corner of articles about the related product, service, company, or entity.
