How to Find Copyrighted or Trademark Phrases

By Anna Assad

Before using a specific phrase in your own work or for profit, it is important to check whether your choice of phrase is copyrighted or trademarked. You might face a civil lawsuit if you use a copyrighted or trademarked phrase without the owner's permission. A copyright grants legal protection to an artist's work and a trademark protects a phrase, a word, a symbol, a design or a combination of those elements that the public identifies with a specific person, business or organization. For example, a business slogan would be trademarked, but a distinct phrase that is part of a literary work would be copyrighted. Registration of a copyright or trademark allows the owner to take legal action against unauthorized use. Copyrighted phrases are usually registered with the United States Copyright Office, and trademarked phrases are registered with the United States Patent and Trademark Office.


Step 1

Go to the Trademark Electronic Search System at the official website of the U.S. Patent and Trademark Office. Use the "Basic Word Mark Search (New User)" search. Enter the phrase into the "Search Term" field; leave the default search options set for a basic search. The default search options are "Combined Word Mark" with "All Search Terms (AND)." These settings will return results containing all the words in the phrase and search word variations. View results to see trademarked phrases.

Step 2

Widen the search and search again if you're not sure of the exact phrase. Change the "Results Must Contain" search option to "Any Search Terms (OR)." This will return results that contain parts of the phrase you are searching for.

Step 1

Go to the official website of the United States Copyright Office to use its online "Public Catalog Search" for works copyrighted after 1978. Use the "Keyword" search field for phrases in copyright records. Surround the phrase with double quotation marks to search for the precise phrase.

Step 2

Check the results for the phrase you want. Results are shown by the title of the works that contain the phrase, and are arranged alphabetically.

Step 3

Search again using the "Keyword" search if the exact phrase you are looking for doesn't appear in the results. Use some distinctive words from the phrase. For example, if searching, "The brown shoehorn," omit the words "the" and "brown." "Shoehorn" is the less common word. Put a "+" in front of each search word to narrow the search.

How to Word a Copyright Notice for a Screenplay

A screenplay is the written script of a film and it is automatically protected by copyright from the moment you write it down. You are no longer required to place a copyright notice on your work to gain this protection; nevertheless, a properly formatted copyright notice on your screenplay identifies you as the creator of the work and notifies the public that you are actively protecting your work. If anyone tries to publish your screenplay without your permission or claims it as his own, a copyright notice will make it difficult for that person to argue in court that your copyright was infringed unintentionally.

How to Copyright a Quotation

Quotations are not typically copyrighted; rather, the work of which the quotation is a part of is the copyrighted work. It can be difficult to ensure that a quotation receives copyright protection because "fair use" permits excerpts of a copyrighted work to be used for limited scholarly and educational purposes. However, there are several steps authors can take to protect their quotations and, depending on the length of quotation and how it is published, they may be able to enforce their copyrights.

How to Copyright a Logo by Myself

A logo, like any other artistic image, is protected by copyright law as soon as it's drawn, but registering the copyright for your logo with the U.S. Copyright Office allows you to enforce the copyright in court, and it is simple enough to do by yourself. Registering the copyright on your logo won't protect your business from others who manufacture knock-off goods sold with a similar logo. Registering your logo as a trademark with the U.S. Patent and Trademark Office in addition to registering a copyright of the design will further protect your business.
