What constitutes fair use of copyrighted material?

If you hold a copyright on a book, article, painting, musical composition, software program, etc. that you created in California, you own this creation. It is your intellectual property and others cannot copy, use or sell it without your permission. However, others have the right to fair use of your property without your permission.

As Baylor University explains, fair use means that others can use limited amounts of, or limited excerpts from, your copyrighted material without your permission under very limited circumstances. For instance, all of the following are examples of fair usage:

  • News reporting
  • Criticism
  • Parody
  • Research
  • Scholarship
  • Teaching

Four factors

Generally, the following factors determine whether or not usage by others is fair usage:

  1. Purpose: Why did the person use your work? Was it for commercial purposes or was it for educational or nonprofit purposes?
  2. Nature: What is the nature of your copyrighted work? Did you publish it yourself?
  3. Amount: How much of your copyrighted material did the other person use? Was it a very small amount in relation to the entirety of your work?
  4. Effect: Did the person’s use of your copyrighted material have a negative impact on its potential market? Did it limit your ability to market and sell your copyrighted work yourself?

The answers to these questions can go a long way in determining whether or not the person’s use of your copyrighted material was in fact fair usage of it. The answers also can help you determine if you have a valid copyright infringement lawsuit against the person.


If your copyrighted material is in written form, one way in which a defendant likely can defeat your copyright infringement action is by showing that (s)he put quotation marks around the part (s)he used and listed your book, article, website, etc. as the source.

If your copyrighted material is a painting or other visual arts rendition, a defendant likewise probably can defeat your copyright infringement action by showing that (s)he attributed the copy she made of it to you and/or to your website where you displayed it.


Bear in mind that if you created “your” intellectual property as part of your work as an employee or independent contractor, it is not really yours and you do not hold the copyright on it. Similarly, if you wrote an article that a magazine or journal published, you likely had to transfer all copyright rights to the publication. In such situations, your own subsequent use of the material must be fair usage, even though you were the original creator.

What Our Clients Say

Starting a new business can be a bit scary. Aside from worries of failure, there’s also the hassle of making sure all legal paperwork are properly filed. I reached out to Mr. Wang (Tommy) because of his excellent reviews and reputation and I am so glad I did. He was thorough and meticulous in answering all of my concerns and took time to find out special laws and policies regarding the kind of business I am starting. I could focus on the daily practical side of starting my new office without worry because I felt Tommy was reliable and took my case seriously. My business is opened and it’s all been a smooth start because of Tommy’s help. I have plans to start another business venture in the next few years and I already know I’ll be coming back to Wang IP Law.

I came to Tommy for help reviewing a licensing agreement I had secured with a well-known manufacturer. Tommy made sure I understood all the details in the contract and he negotiated with the company to improve my side of the deal. I mentioned to Tommy at my first consultation that we were looking to expand throughout the US and were investing a lot of money to make a big entrance into the market. I did not think I would have my store open so soon but Tommy also has connections with the local area and realtors to help me secure the location for my first store in the Los Angeles area. Tommy works a lot with the local businesses and he understands how to transition from the Asian market to US market. Within 8 months my store was open for business and fully operating. I must recommend Tommy to any business owners looking for help with contracts and improving their side of the deal. Tommy has the knowledge and experience to make sure there is a smooth process to open for business here, and make sure that your company is set up for success.


I think Tommy and his team by far considered the best people to work with in my 16 business years. Beside quick responses to all my inquiries, they also done things right and providing very professional solutions. I’m highly recommending Tommy and his firm to all business owners.

I have been working on my Utility Patent for almost 4 years. I have hired and fired two very reputable IP firms because with all their expertise and reputation for being some of the top firms in IP Law, I felt a lack of connection and care in my product, time and financial investment. Then I found Tommy and his team. Tommy does not waste time. He and his team are professional and extremely thorough. After 4 years, I finally found a legal team that I felt spent the time to really understand the components of my utility patent. Tommy also very mindful of cost and how and where my money would be better spent. I really feel I am in great hands with Tommy and his team. They have been patient with my revisions. And most importantly, they made me feel that they fully understood the importance this patent is to me. It has been a great and comforting pleasure working with Tommy.
