Q: Can I use the phrases..... Let there be light, or Here's your sign...... as a slogan for my company?

A: There are several existing trademarks for each of these. It's possible you could use it, depending on what category of goods/services your company deals in. You should consult a qualified trademark attorney, who can help you determine whether you are able to use these and if you should seek your own trademark registration(s).

A: LET THERE BE LIGHT is a registered trademark used for ministerial services and candles, and is registered as a slogan used by the University of California for educational services and merchandise; there is also a pending application to register LET THERE BE LIGHT for decorative lighting.

If your proposed usage is for goods or services dissimilar from those, it might be non-infringing. You should consult an experienced trademark attorney for a more comprehensive opinion.

A: The use of common phrases can be tricky in trademark law. "Let there be light" is a well-known biblical phrase, and "Here's your sign" has been popularized by comedian Bill Engvall. Generally, phrases that have become widely used in everyday language may be considered too generic to qualify for trademark protection.

However, the context in which you use these slogans for your company and the distinctiveness they acquire in relation to your goods or services play a significant role in determining trademark eligibility. It would be wise to conduct a thorough search for any existing trademarks and consult with an attorney who practices trademark law to evaluate the likelihood of success in registering these phrases and their risk of potential infringement.
