Patents.

To protect their new invention from being copied, Apple can use patents. Patents grant exclusive rights to the inventor for a limited period of time, typically 20 years, and prevent others from making, using, or selling the patented technology without permission. This allows Apple to protect their innovative technology and maintain a competitive advantage in the market.

To protect their new technology from being copied, Apple can utilize the intellectual property right known as patents.

A patent grants exclusive rights to the inventor for a limited period, typically 20 years, in order to prevent others from making, using, selling, or importing the invention without permission. Patents are commonly obtained for new and inventive products or processes, and they provide a legal framework for Apple to safeguard their innovative technology in iPhones.

Securing a patent involves submitting a detailed patent application to the relevant intellectual property office, such as the United States Patent and Trademark Office (USPTO). This application should clearly describe the invention's technical features and demonstrate its novelty, usefulness, and non-obviousness. Upon approval, the patent is granted, making it legally enforceable and allowing Apple to take legal action against anyone who infringes on their protected invention.

While Apple may also use other intellectual property protections like trademarks, copyrights, and registered designs for various aspects of their products (such as brand names, logos, software interfaces, and product aesthetics), patents are typically the primary means for safeguarding technological innovations.
