Patent disputes in the telecommunications industry are among the most complex forms of international intellectual-property litigation. Modern smartphones depend on thousands of technologies, many of which are incorporated into international technical standards such as 4G LTE and 5G. When companies disagree over the licensing of those technologies, the dispute can quickly spread across multiple countries.
A significant real-world example involved Company A, a major Swedish telecommunications technology company, and Company B, a major Chinese technology group with a global smartphone business. For editorial purposes, the companies are referred to only as Company A and Company B throughout this article.
The dispute involved standard-essential patents (SEPs), 5G technology, FRAND licensing obligations, patent infringement claims, U.S. federal litigation, proceedings before the U.S. International Trade Commission (USITC), and related litigation in Brazil, Colombia and the United Kingdom.
The U.S. Court of Appeals for the Federal Circuit issued an important decision in October 2024 concerning the dispute, and the companies ultimately reached a global patent cross-license agreement in April 2025.
This case provides valuable lessons for Chinese companies that develop and sell technology products in the United States.
Company A and Company B were both participants in the global telecommunications industry and members of the European Telecommunications Standards Institute (ETSI).
Both companies owned large portfolios of patents relating to wireless communication technology.
The dispute centered particularly on 5G standard-essential patents.
Company A alleged that Company B's products implemented patented technologies covered by four of Company A's U.S. 5G patents. Company A also alleged that Company B had failed to satisfy its obligations concerning good-faith negotiations for a patent license.
According to the Federal Circuit's published opinion, Company A made what it described as a “final licensing offer” to Company B on October 11, 2023. On the same day, Company A filed a lawsuit in the United States.
The dispute was therefore not simply about whether a particular smartphone copied a technical invention.
The larger question was:
What happens when a company needs to use patented technology that has become part of an international technical standard?
That question leads directly to SEP and FRAND law.
A standard-essential patent, or SEP, is a patent covering technology that is necessary to comply with a particular technical standard.
For example, a smartphone designed to communicate using a particular 5G standard may need to implement technologies covered by patents declared essential to that standard.
This creates a special economic relationship between the patent owner and the companies implementing the standard.
A patent owner normally has the right to prevent unauthorized use of its patented technology.
However, if the patented technology is essential to an industry standard, refusing access could potentially prevent competitors from producing standards-compliant products.
The Federal Circuit explained that SEP holders can possess significant bargaining power because companies that adopt the standard may become dependent on the relevant technology. (Justia Law)
This is why standard-setting organizations such as ETSI use intellectual-property policies concerning licensing commitments.
FRAND stands for:
Fair, Reasonable and Non-Discriminatory.
The concept is designed to balance the interests of SEP owners and companies that need to implement standardized technology.
A patent owner should receive appropriate compensation for valuable inventions.
At the same time, the owner should not use its position as an SEP holder to demand unreasonable terms from companies that must use the standard.
The Federal Circuit's 2024 opinion noted that both Company A and Company B had made FRAND commitments under ETSI's intellectual-property framework. The court also stated that the parties agreed that the FRAND commitment was a contract governed by French law and included an obligation to negotiate in good faith concerning SEP licenses. (联邦上诉法院)
This made the dispute considerably more complicated than a conventional patent infringement lawsuit.
The parties were not simply arguing:
“Did the product infringe the patent?”
They were also arguing:
“Were the parties negotiating the required license in good faith, and what licensing terms were consistent with FRAND?”
Company A filed its U.S. lawsuit in the Eastern District of North Carolina.
The case involved allegations that Company B infringed four U.S. 5G SEPs and breached its FRAND obligations.
Company B responded by seeking an antisuit injunction.
An antisuit injunction is a court order intended to prevent a party from pursuing or enforcing litigation in another jurisdiction.
This became important because Company A had also pursued patent litigation in Brazil and Colombia, where it obtained preliminary orders affecting Company B's smartphone sales.
Company B asked the U.S. court to prevent Company A from enforcing those foreign injunctions while the U.S. dispute continued.
The district court initially denied Company B's request.
Company B then appealed to the U.S. Court of Appeals for the Federal Circuit.
On October 24, 2024, the Federal Circuit issued its decision in the appeal.
The appellate court vacated the district court's denial and remanded the matter for further consideration.
This did not mean that Company B had won the entire patent dispute.
Instead, the appellate court concluded that the district court had applied the wrong framework when evaluating the request for an antisuit injunction.
The Federal Circuit directed the lower court to reconsider whether the U.S. litigation could sufficiently resolve the foreign proceedings and whether other relevant factors supported the requested injunction.
This distinction is extremely important.
Winning an appeal on a procedural or jurisdictional issue does not necessarily mean winning the underlying patent infringement case.
For businesses publishing legal or IP content, accurately describing this difference is essential.
The case illustrates why U.S. courts can become strategically important even when a patent dispute involves several countries.
Company A and Company B were engaged in litigation in:
● the United States; ● Brazil; ● Colombia; ● the United Kingdom; ● and other jurisdictions.
The U.S. federal court therefore became one part of a much larger global patent dispute.
The Federal Circuit's decision demonstrates that U.S. courts may have to consider how their orders interact with litigation occurring in foreign countries.
For multinational technology companies, patent litigation strategy cannot be separated from international jurisdiction strategy.
A company may need to determine not only where a patent has been infringed, but also which court should decide licensing issues and how decisions in one country may affect proceedings elsewhere.
The dispute was not limited to federal court.
Company A also brought a complaint before the U.S. International Trade Commission under Section 337 of the Tariff Act of 1930.
The USITC initiated Investigation No. 337-TA-1387 in January 2024 concerning certain electronic computing devices and components.
The complaint alleged that products imported into the United States infringed asserted patents.
The respondents included Company B's U.S. entity as well as several Chinese and Hong Kong entities.
This is especially important for Chinese exporters.
A patent dispute before the USITC is not simply another damages lawsuit.
The USITC can issue exclusionary remedies that may affect the importation of infringing products into the United States.
For a company whose business depends on importing smartphones, computers or other electronic devices into America, such proceedings can create substantial commercial pressure.
In December 2024, Reuters reported that an ITC administrative law judge had determined that certain Company B smartphones infringed Company A's 5G wireless patents.
The products reportedly included certain models from Company B's Motorola smartphone lines.
The ruling represented a preliminary victory for Company A in the U.S. trade proceeding, although the full Commission still had to review the matter. (Reuters)
This is an important distinction:
An administrative law judge's initial determination is not necessarily the same as a final Commission determination.
The USITC itself had stated when the investigation was instituted that no decision on the merits had yet been made and that the administrative law judge would first conduct the evidentiary process and issue an initial determination.
For international businesses, understanding these procedural stages is critical.
A conventional patent lawsuit may focus heavily on monetary damages.
A Section 337 investigation can create a different kind of commercial risk.
If the relevant statutory requirements are satisfied, the USITC may issue an exclusion order affecting the importation of infringing products.
For a Chinese company selling smartphones in the United States, this means that a patent dispute can potentially become a market-access problem.
The practical consequences can include:
● interruption of imports; ● pressure on distributors; ● supply-chain disruption;
● increased licensing leverage; ● product redesign; ● additional legal expenses;
● and reputational consequences.
Therefore, Chinese companies entering the U.S. market should treat patent clearance as a commercial issue, not merely a legal compliance exercise.
One of the most interesting features of this case is that the parties were not merely fighting over infringement.
The broader dispute involved:
patent infringement + SEP licensing + FRAND obligations + good-faith negotiations + foreign injunctions + cross-border jurisdiction.
This is a useful example of how modern patent disputes can become commercial negotiations.
For technology companies, a patent may have value in several ways.
It can:
● prevent competitors from using technology; ● generate royalty income;
● support cross-licensing; ● strengthen negotiating power;
● support market access; ● and protect research and development investment.
The parties therefore had incentives to resolve the dispute commercially rather than continue litigation indefinitely.
In April 2025, Company A and Company B announced that they had reached a global patent cross-license agreement and agreed to settle all ongoing litigation between them.
Reuters reported that the agreement covered the parties' global patent dispute involving 4G and 5G wireless technologies. The companies also agreed to binding arbitration to determine the final licensing terms. (Reuters)
The settlement was significant because the litigation had spread across multiple jurisdictions.
Instead of continuing separate lawsuits in different countries, the companies moved toward a global licensing framework.
The financial details were not fully disclosed.
Therefore, it would be inaccurate to claim that one side “won” a particular amount of money.
The more accurate conclusion is that international patent litigation created sufficient commercial pressure for both parties to reach a global cross-license settlement.
This case offers several practical lessons.
A Chinese company's domestic patent portfolio does not automatically protect its products in the United States.
If a technology will be commercially important in America, corresponding U.S. patent protection should be considered.
Before launching a technology product in the United States, companies should evaluate whether third-party patents may cover important product functions.
This is known as freedom-to-operate (FTO) analysis.
An FTO review is not the same as searching for identical patents. It requires analysis of patent claims, legal status, territorial scope and product implementation.
Companies developing smartphones, 5G equipment, IoT products and connected devices should identify potentially relevant SEPs.
A product can comply with an industry standard while simultaneously implicating numerous third-party patents.
Companies should maintain:
● engineering documents; ● product specifications; ● source code;
● development records; ● testing results; ● patent analyses;
● licensing correspondence.
Such materials can become important during discovery and litigation.
If a company is implementing SEPs, licensing negotiations should be documented carefully.
Good-faith negotiation can become a legal issue in its own right.
Companies should preserve offers, counteroffers, technical discussions, royalty analyses and correspondence.
The dispute is particularly relevant to Chinese manufacturers and technology companies expanding internationally.
Many Chinese businesses now sell:
● smartphones; ● laptops; ● tablets; ● smart watches; ● IoT equipment;
● telecommunications equipment; ● automotive electronics; ● wireless devices.
These products may implement technologies covered by international standards.
Consequently, a company can face patent risk even when it has independently developed its own product.
The company may not have copied another manufacturer's product.
Instead, it may have implemented a technical standard containing patented technologies.
That is why patent licensing has become a major strategic issue for global technology companies.
The real dispute between Company A and Company B provides a valuable example of how complicated U.S. patent litigation can become when 5G technology and standard-essential patents are involved.
The dispute included U.S. federal litigation, USITC Section 337 proceedings, 5G patents, FRAND commitments, foreign injunctions, an appeal to the Federal Circuit, and ultimately a global cross-license agreement.
For Chinese companies, the central lesson is clear:
Entering the U.S. market requires more than obtaining patents for your own technology. Companies must also understand the third-party patent landscape surrounding their products.
A strong international patent strategy should therefore combine:
patent filing + freedom-to-operate analysis + SEP assessment + licensing strategy + litigation preparedness.
The case also demonstrates that patent litigation can affect much more than damages.
A patent dispute can potentially influence whether products can enter the U.S. market, how much a company pays for technology licenses, and how much negotiating power it has in global commercial relationships.
For Chinese technology companies seeking long-term international expansion, patents should therefore be treated as both legal rights and strategic business assets.
