A proprietary license is a type of software license that grants the licensee the right to use a product under specific conditions set by the owner. This means that the software is owned by a company or individual, and users typically cannot modify, share, or distribute it without permission. Examples of proprietary software include popular applications like Microsoft Office and Adobe Photoshop. These licenses often come with restrictions that protect the intellectual property of the creator. Users usually pay a fee to obtain the license, which may include support and updates. Proprietary licenses are common in commercial software, where the goal is to maintain control over the product and its distribution.
