[Essential Guide] What Are Standard Essential Patents (SEPs)? From Core Concepts to Global Trends

In today’s business landscape, particularly within manufacturing and technology sectors, there is a critical term every leader must understand: Standard Essential Patents (SEPs).

Once an issue confined strictly to telecom giants, SEPs have evolved into a matter of corporate survival for any company involved in “connected devices” and the Internet of Things (IoT)—including automotive, smart home appliances, and medical devices.

Even if you think, “Our company isn’t a tech firm, so this doesn’t apply to us,” this comprehensive guide will break down the foundational concepts and latest global movements of SEPs in an easy-to-understand format.

1. What Is a Standard Essential Patent (SEP)?

Patents That Are “Un-designable” When Complying with Standards

An SEP is a patent that protects technology essential to implementing a technical standard, such as Wi-Fi, 5G, Bluetooth, or USB.

With ordinary patents, companies can often engage in a “design-around”—altering their technical configuration to avoid infringing on a competitor’s rights. However, when manufacturing a product meant to comply with industry standards, skipping that underlying technology is not an option. In intellectual property economics, this is known as the “lock-in effect.”

Bypassing the Patent	It is entirely possible to “design around” the patent by adopting alternative methods or proprietary engineering.	Bypassing is impossible due to the structural barriers of the standard. To enter the market, you must use the patented technology.

The “FRAND” Commitment: A Promise of Fairness

If a company could arbitrarily hike up royalty rates and monopolise a market simply because its technology was adopted into a global standard, the standard itself would fail to proliferate.

To prevent this market failure, patent holders must declare to Standards Development Organisations (SDOs) that they commit to licensing their patents under FRAND terms:

• Fair: Not imposing exploitative or unreasonable licensing terms.
• Reasonable: Keeping licensing fees economically viable and sensible.
• Non-Discriminatory: Offering licenses to anyone without choosing favourites or locking out specific competitors.

In short, an SEP is bound by a globally recognised pact: “I will grant a license to any implementer under honest prices and balanced conditions.”

2. Why Are SEPs Gaining Traction Across All Industries?

Spreading into Non-Tech Industries: Automotive and IoT

Today, the most intense legal and commercial battles are taking place outside the traditional telecom sector.

A symbolic turning point occurred when telecom pioneers like Nokia sought licensing fees from major automotive manufacturers (such as Toyota and Honda), requesting fixed rates like $15 per connected vehicle. Suddenly, traditional mechanical manufacturers were pulled into massive licensing negotiations valued at billions of dollars.

The Proliferation of Patent Pools

Negotiating with thousands of individual patent holders one by one is commercially unfeasible. To streamline this process, patent pools (such as Avanci) act as a centralised licensing window for multiple innovators. This allows implementers (the manufacturers making the products) to clear thousands of essential rights in a single transaction.

This trend extends far beyond connected cars. Mass licensing demands via patent pools are rapidly spreading across the broader consumer IoT ecosystem—encompassing smart meters, connected home appliances, and electric vehicle (EV) charging stations.

3. The Two Major Conflicts in Licensing Negotiations

When negotiating a standard license, two major friction points routinely surface between patent owners (licensors) and product manufacturers (implementers):

① Who should take the license? (Friction Over the Contracting Entity)

• License to All (LTA): The philosophy that any tier within a supply chain—including component or chip manufacturers—should have the legal right to secure a direct license.
• Access for All (AFA): The philosophy that licensing should occur exclusively at the end-product manufacturer level. Proponents argue that component makers only need operational “access” to the technology, while the actual agreements and payments should remain focused on the final device makers.

② How should royalties be calculated? (Friction Over the Valuation Base)

• SSPPU (Smallest Saleable Patent-Modelling Unit): A calculation method that bases royalties on the price of the smallest component utilising the patent, such as the individual baseband cellular chip (typically costing only a few dollars).
• EMV (Entire Market Value): A calculation method that bases royalties on the price of the entire finished product, such as the smartphone, automobile, or smart appliance (ranging from hundreds to tens of thousands of dollars).

4. Global Regulatory Frameworks: The “Good Faith” Negotiation Process

To mitigate systemic litigation risks, governments around the world have established strict operational frameworks. For example, Japan’s Ministry of Economy, Trade and Industry (METI) and the Japan Patent Office (JPO) published the “Guidelines for Licensing Negotiations Involving Standard Essential Patents.” These metrics have become an international benchmark for courts to evaluate whether parties are acting in “good faith.”

A typical good-faith negotiation follows a structured 4-step framework:

1. The Patentee’s Licensing Offer: The patent holder initiates negotiations by providing evidence of alleged infringement, typically via detailed claim charts.
2. The Implementer’s Response: The product manufacturer must promptly express a clear willingness to secure a license under FRAND terms (the “FRAND expression of willingness”).
3. Delivery of Specific Terms: The patent holder delivers a specific licensing rate proposal accompanied by a clear explanation of its underlying calculation logic.
4. The Counter-Proposal: If the manufacturer cannot agree to the initial terms, they cannot simply walk away or stone-wall; they must provide a concrete, economically substantiated counter-proposal.

5. [Defence Strategy] What If Your Company Receives an SEP Licensing Demand Letter?

• 1. Never Ignore the Letter: Silence is catastrophic. Immediate abandonment of communication ruins your status as a good-faith negotiator, creating an immediate vulnerability to court-mandated product injunctions.
• 2. Retain Specialised IP Counsel Immediately: Defending against an SEP assertion requires a completely different playbook and set of international legal rules compared to a traditional patent dispute. It is essential to work with patent attorneys and legal experts (lawyers) who possess a proven track record in global standard licensing negotiations.

6. Conclusion: Navigating the Future of IoT Business

As the Internet of Things (IoT) becomes an inescapable reality, managing Standard Essential Patents is transforming from a niche intellectual property (IP department) exercise into a foundational pillar of corporate governance and corporate strategy.

• Even completely non-tech traditional enterprises can suddenly find themselves on the receiving end of an SEP assertion.
• Global compliance parameters remain in constant flux, highlighted by sweeping international regulatory shifts such as the European Union’s emerging SEP Regulations.
• It is critical to carefully document every step, timestamp, and exchange of your licensing communications to legally establish your company’s “good faith” status if a dispute escalates.

Utilising standard compliance frameworks means interacting with shared social infrastructure. Navigating how to fairly value and compensate these core technology blocks is a crucial capability required to succeed in global competition.
