Standards: Why Plugs Fit and Phones Connect

How technical standards let products work together, why standard battles can decide industries, and how standard-essential patents are licensed.

Your phone connects to networks worldwide, your charger fits many devices, and web pages load on any browser. This works because of standards: shared technical rules that let products work together.

Why standards matter

Compatibility: products from different firms work together.
Network effects: the more people use a standard, the more valuable it becomes.
Lower costs: firms can produce for a large market, and consumers can switch brands.
Innovation: firms can build on a common base.

How standards are set

Standards bodies: organisations like the International Telecommunication Union, the IEEE for Wi-Fi, and national bodies like the Bureau of Indian Standards.
Industry consortia: groups of companies agree on standards, such as USB or Bluetooth.
Market battles: sometimes competing standards fight until one wins.

Standard battles

VHS vs Betamax: in the 1970s and 1980s, VHS won the home video format war, partly because of longer recording time and wider availability of films.
Blu-ray vs HD DVD in the 2000s.
Chargers: the European Union required USB-C as a common charger for many devices from the end of 2024, and India adopted a similar approach.

Standard-essential patents

Some standards use patented technology. If a patent is essential to a standard, anyone following the standard needs a licence. These are called standard-essential patents.

To prevent abuse, patent holders often commit to licence on FRAND terms: fair, reasonable and non-discriminatory. Disputes over what counts as FRAND have led to major court cases, including in India’s courts, over mobile phone patents.

Standards as policy

In India, the government uses Quality Control Orders to require BIS certification for many products, aiming to improve quality and reduce low-quality imports. Critics argue some orders raised input costs for manufacturers, and the government withdrew or relaxed several in 2025.

The universal charger

A family owns phones, earbuds and a laptop from different brands. With a common USB-C standard, one charger works for all. They buy fewer chargers, and less electronic waste is created.

Thinking the best technology always becomes the standard

Timing, network effects, alliances and availability of complementary products often decide which standard wins.

Key takeaways

Standards enable compatibility, network effects and lower costs.
They are set by bodies, consortia or market battles.
Standard-essential patents are licensed on FRAND terms.
Standards can also be used as policy, such as India's Quality Control Orders.
