A smartphone is a mobile device that combines the functionality of a traditional mobile phone with advanced computing capabilities. It typically has a touchscreen interface, allowing users to access a wide range of applications and services, such as web browsing, email, and social media, as well as multimedia playback and streaming. Smartphones have built-in cameras, GPS navigation, and support for various communication methods, including voice calls, text messaging, and internet-based messaging apps.

The multinational technology corporation Apple Inc. has been a participant in various legal proceedings and claims since it began operation and, like its competitors and peers, engages in litigation in its normal course of business for a variety of reasons. In particular, Apple is known for and promotes itself as actively and aggressively enforcing its intellectual property interests. From the 1980s to the present, Apple has been plaintiff or defendant in civil actions in the United States and other countries. Some of these actions have determined significant case law for the information technology industry and many have captured the attention of the public and media. Apple's litigation generally involves intellectual property disputes, but the company has also been a party in lawsuits that include antitrust claims, consumer actions, commercial unfair trade practice suits, defamation claims, and corporate espionage, among other matters.
A tablet computer, commonly shortened to tablet, is a mobile device, typically with a mobile operating system and touchscreen display processing circuitry, and a rechargeable battery in a single, thin and flat package. Tablets, being computers, have similar capabilities, but lack some input/output (I/O) abilities that others have. Modern tablets largely resemble modern smartphones, the only differences being that tablets are relatively larger than smartphones, with screens 7 inches (18 cm) or larger, measured diagonally, and may not support access to a cellular network. Unlike laptops, tablets usually run mobile operating systems, alongside smartphones.
Android is a mobile operating system based on a modified version of the Linux kernel and other open-source software, designed primarily for touchscreen mobile devices such as smartphones and tablets. Android is developed by a consortium of developers known as the Open Handset Alliance, though its most widely used version is primarily developed by Google. It was unveiled in November 2007, with the first commercial Android device, the HTC Dream, being launched in September 2008.
A mobile operating system is an operating system used for smartphones, tablets, smartwatches, smartglasses, or other non-laptop personal mobile computing devices. While computers such as typical/mobile laptops are "mobile", the operating systems used on them are generally not considered mobile, as they were originally designed for desktop computers that historically did not have or need specific mobile features. This line distinguishing mobile and other forms has become blurred in recent years, due to the fact that newer devices have become smaller and more mobile unlike hardware of the past. Key notabilities blurring this line are the introduction of tablet computers, light laptops, and the hybridization of the two in 2-in-1 PCs.

The history of tablet computers and the associated special operating software is an example of pen computing technology, and thus the development of tablets has deep historical roots. The first patent for a system that recognized handwritten characters by analyzing the handwriting motion was granted in 1914. The first publicly demonstrated system using a tablet and handwriting recognition instead of a keyboard for working with a modern digital computer dates to 1956.
A smartwatch is a portable and wearable computer device in a form of a watch; modern smartwatches provide a local touchscreen interface for daily use, while an associated smartphone app provides management and telemetry, such as long-term biomonitoring. While early models could perform basic tasks such as calculations, digital time telling, translations, and game-playing, smartwatches released since 2015 have more general functionality closer to smartphones, including mobile apps, a mobile operating system, and WiFi/Bluetooth connectivity. Some smartwatches function as portable media players, with FM radio and playback of digital audio and video files via a Bluetooth headset. Some models, called watch phones, have mobile cellular functionality such as making telephone calls.
Chromebook is a line of laptop and tablet computers that runs using ChromeOS, an operating system developed by Google.
The smartphone wars or smartphone patents licensing and litigation refers to commercial struggles among smartphone manufacturers including Sony Mobile, Google, Apple Inc., Samsung, Microsoft, Nokia, Motorola, Huawei, LG Electronics, ZTE and HTC, by patent litigation and other means. The conflict is part of the wider "patent wars" between technology and software corporations.
Apple Inc. v. Samsung Electronics Co., Ltd. is the general title of a series of patent infringement lawsuits between Apple Inc. and Samsung Electronics in the United States Court system, regarding the design of smartphones and tablet computers. Between them, the two companies have dominated the manufacturing of smartphones since the early 2010s, and made about 40% of all smartphones sold worldwide as of 2024. In early 2011, Apple began litigating against Samsung in patent infringement suits, with Samsung typically filing countersuits with similar allegations. Apple's multinational litigation over technology patents became known as part of the smartphone wars: extensive litigation and fierce competition in the global market for consumer mobile communications.
