Dolby invents audio and video technologies and earns most of its money by licensing them. Its best-known are Dolby Atmos, a three-dimensional surround sound format, and Dolby Vision, a high dynamic range picture format. Device makers such as television, smartphone, PC and soundbar companies pay Dolby to build these technologies, and its audio codecs (which compress and decode sound), into their products. Dolby says about 1,000 manufacturers license its technology. Content creators and distributors use its tools to make and deliver films, shows, music and sports in these formats.
Licensing, covering branded technology and patents, brought in 93% of revenue in fiscal 2025. The rest came from products and services, such as Dolby Cinema and cinema equipment. By market, broadcast products such as televisions and set-top boxes made up 34% of licensing revenue, mobile 22%, consumer electronics 12% and PCs 12%. Dolby also gets fees for running patent pools, in which patent owners license their patents together.
Dolby depends on its intellectual property. As of September 26, 2025, it held approximately 28,400 issued and effective patents. The filing warns that the Dolby family and its affiliates may take actions in their own interests that other stockholders do not view as beneficial.
