It depends on the use. One example that has been established by case law to be "fair use" is a car repair shop making a print ad which includes the logos of the cars they specialize in.
The biggest difference between a use that would require permission and one that might not is whether it is perfectly clear that you are not representing the company whose logo you are using. If your use makes it appear that the material is coming from Saab, say, you would absolutely need permission.
It depends on the type of use. One unlicensed use supported by case law is the use of car manufacturer logos in print advertising for auto repair companies (for example to say "we specialize in..."). Most other uses would require permission.
Contact the business affairs or legal affairs department, generally in writing. Be specific about your proposed use.
Ask them in writing, and be specific.
A few unlicensed uses have been judged to be fair use, but the vast majority of uses of another's trademark logo requires permission.
No, you cannot use a company's trademarked logo without their permission for any reason.
If the logo is copyrighted then you need permission to use it.
You need to get permission first.
It depends on how you are using it.
Yes, it is illegal to use a company's logo on your website without their permission because logos are typically considered intellectual property and using them without authorization may infringe on the company's rights. It is best to seek permission or use alternative methods to represent the brand on your website.
One would contact Dell in order to get permission to use the Dell logo. Using their logo requires express written consent so one must contact them by phone, email or letter. They have contact information on their official website.
With permission.
No, not unless you have it written on paper that you are allowed to use their logo. In the copywrite world, it is considered stealing to use some company's logo without permission.
Yes. If the copyrighted police department logo is central to your story -- it may not be -- you can approach the municipality and request permission to use the image. Be prepared to show storyboards or other visual examples of how you intend the logo to be used in the story, and explain its pivotal place in the story. Once permission is granted -- in writing -- you can use the logo in the ways you describe using it when you request permission. Otherwise, hire a graphic artist to design a logo that conveys the authenticity that your script requires.
Unless your use of the logo could be considered "fair use" the only legal way to use someone elses' intellectual property would be to ask permission.
Not unless you get express permission from that team. They will sue you if you don't get permission and they find out. You most likely won't get permission even if you ask.
