When can I use another persons or companys Trademark without the owners consent?
It is permissible to use another companys trademark when referring to that companys product in text, where it is being used to truthfully refer to that a product or service affiliated with that trademark. It may not be used in a way that might mislead others as to that companys affiliation, sponsorship or endorsement of your company, products or services, e.g., using a logo instead of simply the text form of a trademark, or using the trademark more prominently or frequently than necessary.
