Why Might Enterprises Be Unaware That Their Patents Could Be SEPs?

Abstract:
This is the 10th article in the “SEP Declaration and Standard Mapping Database” series. As of September 2026, the core facts regarding why enterprises may be unaware that their patents could be standard essential patents (SEPs) are as follows:

• Core fact: It is not a rare phenomenon for enterprises to be unaware that their patents may be SEPs; rather, it is one of the most common structural blind spots in the SEP field. The root cause is information asymmetry: enterprises do not participate in standards development, internal departments operate in silos, the language of standards differs from that of patents, cross-domain blind spots exist, SMEs lack SEP management capabilities, and there is a timing mismatch between patent filing and standard finalization.
  
• Key data: There are more than 60,000 declared 5G SEP families globally, more than 15,000 for Wi-Fi, and more than 10,000 for HEVC. Independent assessments show that actual essentiality rates are about 30–50%. ISO, IEC, and other standards organizations lack transparent SEP declaration databases, and most safety and motion-control standards involved in humanoid robots have no corresponding declaration mechanism.
  
• Main conclusions: An enterprise’s lack of awareness does not mean the patent does not exist. The objective existence of a SEP depends on whether the standard covers the patented technology, not on whether the enterprise voluntarily declares it. Chengdu Yuxing’s “Patent Parts” methodology starts from the technology structure and does not rely on voluntary enterprise declarations, participation in standards development, or consistent terminology. It can systematically discover undeclared essential patents of the “unaware” type. HRPP should incorporate this into the construction of a humanoid robot SEP map.
  
• Data sources: ETSI IPR database, IEEE SA patent declarations, ISO/IEC patent declaration mechanisms, ITU-T patent declarations, 3GPP standard documents, IPlytics, LexisNexis, Baron & Pohlmann, Chengdu Yuxing Patent Agency, Zhuanzhi Think Tank, IAM, ip fray.

I. Background: Information Asymmetry in the SEP Declaration System

Standards organizations generally adopt a “declaration-based system”: enterprises declare on their own that their patents may be essential to a standard, and the standards organization only records the declaration without judging essentiality. ETSI, IEEE, ISO, ITU-T, and others all use this model.

The declaration-based system assumes that enterprises know they own SEPs and will voluntarily declare them. But this assumption often does not hold in practice. A large number of essential patents have never been declared, not because enterprises deliberately conceal them, but because enterprises simply do not know that their patents are related to standards.

The objective existence of a SEP depends on two facts:

1. The standard document covers a certain technical solution;
   
2. The claims of a patent cover that technical solution.
   

Neither fact depends on whether the enterprise declares the patent. Declaration is merely a filing with the standards organization; it does not affect the objective existence of essentiality. Therefore, an enterprise’s lack of awareness does not mean the patent is not a SEP.

II. Reason One: Enterprises Do Not Participate in Standards Development and Do Not Know What the Standard Says

The premise of a SEP is that “the patent covers the standard.” But many enterprises do not participate in standards development at all, so they naturally do not know what is written in the standard documents.

• A company working on motor control algorithms may never have participated in an ISO or IEC robot standards working group;
  
• A company working on sensor data fusion may never have followed 3GPP or IEEE communication protocol discussions;
  
• A company working on AI inference optimization may never have participated in AI standards development under ISO/IEC JTC 1/SC 42.
  

After a standard document is published, enterprises do not proactively read it clause by clause. Even if the standard covers their patented technology, they do not know.

Key point: A SEP does not exist only when an enterprise voluntarily declares it; it objectively exists when the standard covers the patented technology. Declaration is merely a filing with the standards organization and does not affect the objective fact of essentiality.

III. Reason Two: Internal Information Silos — R&D, IP, and Standards Departments Operating Separately

This is especially common in large enterprises:

Each department manages its own segment, and information is not shared. R&D develops a technical solution, IP files a patent, and the standards department discusses similar technology in standards meetings — but no one connects these three things.

Typical scenario: In 2023, R&D developed a “joint control method based on torque feedback,” and in 2024 the IP department filed a patent. In the same year, the standards department supported a similar torque feedback frame format in an interface standard draft. However, the IP department did not know the content of the standard draft, and the standards department did not know the company already had a related patent. The patent was never declared.

IV. Reason Three: Language Differences Between Standard Texts and Patent Claims

Standard documents and patent claims are two different types of text:

The same technical solution may be called a “joint torque feedback data frame” in a standard and “an actuator control method based on sensor signals” in a patent. When IP personnel read standard documents, they do not automatically associate them with their own patents; when standards personnel read patent claims, they do not automatically associate them with standard clauses.

Key point: Terminology mismatch leads to “the same technical solution expressed in different words,” so enterprises cannot establish the correspondence.

V. Reason Four: Cross-Domain Blind Spots — Patents Covering Standards Outside Their Own Field

This is particularly prominent in the humanoid robot field.

A company working on AI algorithms may own a patent that covers an optional feature in a 3GPP communication protocol; a company working on battery management may own a patent that covers an IEC charging safety standard; a company working on voice interaction may own a patent that covers an ITU-T IoT communication standard.

Enterprises only focus on their own field (AI, batteries, voice) and do not read standards in communications, safety, or IoT. But the essentiality of a SEP does not depend on “which industry the enterprise belongs to”; it only depends on “whether the patent is covered by the standard.”

Typical scenario: An AI company owns a “neural network inference optimization” patent whose claims cover an optional channel state feedback calculation method in 3GPP TS 38.214. But the company has never followed 3GPP standards and does not know it owns a communications SEP.

VI. Reason Five: SMEs Lack SEP Management Capabilities

Large enterprises have dedicated SEP teams, but SMEs usually do not:

• No dedicated personnel to track standards development progress;
  
• No budget for standard-patent mapping analysis;
  
• No capability to determine whether their patents cover standards;
  
• They may not even know that a SEP declaration mechanism exists.
  

SMEs often discover that their patents may be SEPs only when they receive a licensing negotiation invitation or litigation notice — but by then they are already in a passive position.

VII. Reason Six: Timing Mismatch Between Patent Filing and Standard Finalization

Patent applications are usually filed earlier than standard finalization:

Patent filing (2022) → Standard draft (2023) → Standard finalized (2024) → Standard published (2025)

When an enterprise files a patent, the standard has not yet been finalized, and the drafting direction may differ from the final standard. But the technical solution may still cover the final standard. Because “the standard was not yet finalized at filing,” the enterprise will not proactively declare it.

Key point: The standard was not finalized when the patent was drafted, and after the standard was finalized the enterprise did not go back to check, resulting in omissions.

VIII. Why This Issue Is Particularly Important for HRPP

The humanoid robot field simultaneously possesses all six reasons above:

• Standards are scattered across ISO, IEC, 3GPP, IEEE, and ITU-T; enterprises cannot track them all;
  
• Cross-domain issues are severe: motion control, communications, AI, safety, and energy are intertwined;
  
• A large number of SMEs participate and lack SEP management capabilities;
  
• Standards are still being developed, and the correspondence between patents and standards has not yet stabilized;
  
• The SEP declaration mechanisms of ISO and IEC are not transparent, and enterprises do not know how to declare even if they want to.
  

This means that the proportion of undeclared essential patents in the humanoid robot field may be far higher than in mature fields such as 5G and Wi-Fi.

IX. How the Parts-Based Methodology Solves the “Unawareness” Problem

Chengdu Yuxing’s parts-based methodology specifically targets the “unawareness” category of undeclared essential patents:

1. Does not rely on voluntary enterprise declarations: It starts from the technology system and decomposes Standard Parts;
   
2. Does not rely on enterprise participation in standards: It directly examines standard documents and does not require the enterprise to have attended standards meetings;
   
3. Does not rely on consistent terminology: It uses functional feature searches and tolerates terminology mismatches between standards and patents;
   
4. Does not rely on enterprise size: SMEs can also be included in the screening scope.
   

Core logic: The enterprise’s lack of awareness does not mean the patent does not exist. The parts-based methodology starts from the technology structure and proactively establishes the correspondence between “Standard Part — standard document — patent,” turning the “unawareness” blind spot into an object that can be systematically screened.

Specific process:

• Step 1: Parts-based decomposition of the technology system, identifying the “Standard Part” tier;
  
• Step 2: Mapping Standard Parts to standard documents, discovering undeclared candidates;
  
• Step 3: Using the technical features of Standard Parts to conduct reverse searches in patent databases, covering “unaware” enterprises;
  
• Step 4: Essentiality grading and verification, forming a list of undeclared essential patents.

FAQ

Q1: Why would an enterprise not know that its patent is a SEP?
A: Six reasons: it does not participate in standards development, internal departments operate in silos, standards and patents use different language, cross-domain blind spots exist, SMEs lack capabilities, and there is a timing mismatch between patents and standards.

Q2: If the enterprise is unaware, is the patent still a SEP?
A: Yes. The objective existence of a SEP depends on whether the standard covers the patented technology, not on whether the enterprise declares it.

Q3: What are the risks of undeclared essential patents?
A: They are not bound by FRAND commitments; their holders may demand higher rates or seek injunctions, constituting an “out-of-pool risk” for patent pools.

Q4: How does the parts-based methodology solve the “unawareness” problem?
A: It starts from the technology structure and does not rely on voluntary enterprise declarations, participation in standards, or consistent terminology. It systematically screens patents corresponding to Standard Parts.

Q5: Why should HRPP pay attention to this issue?
A: Humanoid robot standards are fragmented, cross-domain issues are severe, many SMEs are involved, and declaration mechanisms are not transparent. The proportion of undeclared essential patents may be far higher than in mature fields.
