If you file a fictitious business name (a name different from your real name) statement, it generally means you have the exclusive right to use that name in your county. This holds true if you're the first to file and you're actually doing business under that name. However, this claim can be challenged, and the responsibility to present evidence shifts to the person challenging it.

This law section indicates that a certain presumption related to fictitious business names is valid until either the business name statement is officially abandoned, expired, or a new statement hasn't been filed by anyone taking over the business name.

This law states that a fictitious business name statement filed after January 1, 1971, is considered to have been filed on July 1, 1971, if it aligns with the requirements from a specific chapter in the 1970 Statutes. For the filing date to be valid, the original certificate must have been first filed under an older section of the Civil Code and must not have expired before being filed under another specific chapter of the Business and Professions Code.

This section clarifies that nothing in this chapter mandates or forbids the filing of a fictitious business name statement in any county unless specifically required or prohibited by another law, Section 17910.

This law states that when you officially form a company in California, whether it's domestic or foreign, by filing the appropriate documents, you're generally considered to own the rights to your company's name within the state, as well as any similar names that might confuse people. This means if you were the first to claim that name and are actively doing business with it, you're presumed to have the exclusive right to use it. If you're a foreign company with permission to do business here, you're recognized as established from when you first got that permission. This presumption can be challenged, meaning it's not an absolute guarantee but shifts the responsibility to the challenger to prove otherwise.

This section explains how to determine who gets the exclusive right to use a trade name in a county when there's a conflict between a corporation and another business registrant. The one who filed their business name registration first and is actively doing business with that name will generally have the stronger claim to use it. This applies even if the names are confusingly similar, and the first to file has a presumption of exclusive rights over others who filed later.

Just because a corporation files its articles of incorporation doesn't mean it can automatically use any corporate name it wants. The name must not infringe on someone else's trademark rights under federal law, state trademark law, the Fictitious Business Name Act, or common law rights. The Secretary of State will inform each new corporation of this rule.

Filing a fictitious business name statement in California doesn't automatically give you the right to use a business name if it infringes on someone else's rights. This includes issues with trademarks, trade names, or rights protected under federal and common law.
