A technical standard is a shared specification for how products connect or work, so that firms can make compatible products without negotiating one by one. Plugs, file formats and network protocols all depend on them.

Types of technical standards
- Formal: agreed through an official process at a standards body such as ISO, IEEE or ETSI.
- De facto: become the norm because the market adopts them, whoever designed them.
- Open: anyone can use the specification, free or on fair licence terms.
- Proprietary: owned by one firm, which decides who may use it and on what terms.
Key factors
- Pressure to adopt. Demands from regulators, large customers or dominant partners are the most consistent driver of adoption in research studies.
- Trust in the standards body. Firms prefer bodies with broad membership, equal votes and fair licence rules.
- Where profit moves. Standardising one part makes it cheap, so profit shifts to the parts that remain scarce.
- Duties for the owner. The firm whose design becomes the standard also becomes the main target for regulators and for rivals’ demands.
Examples
Tesla. In November 2022 Tesla opened its charging connector design to other carmakers and renamed it the North American Charging Standard. Ford, General Motors and many other carmakers committed to it during 2023, and it was later published as an industry standard, SAE J3400. A proprietary design became a de facto standard, then a formal one.
EU common charger. Since December 2024 most new phones, tablets and cameras sold in the EU must have a USB-C port for wired charging. The rule turned a widely used standard into a legal requirement, so one cable now charges devices from different makers.
Frequently asked questions
What is the difference between a standard and an API?
An API is an interface that one owner publishes and can change. It becomes a standard only when many firms build to it and no single party can change it freely.
What are standard-essential patents?
Patents that any product following a standard must use. Holders usually promise to license them on fair, reasonable and non-discriminatory terms, known as FRAND, so every maker can follow the standard.
Why do firms help create standards they will share with rivals?
A shared standard can grow the whole market faster than a private one, and the firms that shape it can steer the design towards their own technology.
Do standards slow innovation?
They can lock in an older design once many products depend on it. They also speed innovation, because firms build on a shared base instead of each solving the same compatibility problem.
