The term "proprietary" refers to something that is owned by a specific individual or company. This can include products, technologies, or information that are protected by patents, copyrights, or trade secrets. For example, a software program developed by a company may be proprietary, meaning only that company has the rights to use, modify, or distribute it. In business, proprietary information often gives a competitive advantage. Companies may keep their formulas, designs, or processes secret to prevent others from copying them. This exclusivity can help maintain market position and profitability, as competitors cannot easily replicate proprietary assets.
