DUBLIN, Feb. 20, 2024 /PRNewswire/ -- The "GaN Electronics Patent Landscape Analysis 2023" report has been added to  ResearchAndMarkets.com's offering.

Research and Markets Logo

In this context, the GaN Electronics Patent Landscape report aims to understand what is the strategy of players to consolidate their position in the emerging power and RF GaN markets and to limit the risks and uncertainties related to the adoption, industrialization and commercialization of a new power and RF semiconductor technologies (investment, geopolitical and IP risks).

What's more, the report identifies well-established IP players, IP challengers and newcomers, which are not yet in the power or RF GaN markets and thereby may represent either a threat (future IP and market challengers) or an opportunity to access external innovation (M&A targets, partnerships, IP licensing), depending on the perspective.

Eventually, the report positions early market players in the global IP competition, as these players are the most likely to assert their patents against new players entering the power or RF GaN markets, to maintain and expand their market leadership.

Methodology for GaN electronics patent selection and patent analysis

The patent search covers inventions across the whole GaN value chain, from materials (wafers and epiwafers) to circuits, targeting any kind of electronic applications. The selection is mainly based on the analysis patent claims:

In the upstream supply chain (wafers, epiwafers, devices), relevant inventions are required to focus specifically on GaN materials and devices. A generic invention, i.e., applicable to different power or RF semiconductors, is not be considered as relevant.

In the downstream supply chain (packaging, modules, circuits, applications), generic inventions, applicable to GaN or SiC or Si in power applications or applicable to GaN or GaAs or Si in RF applications, are considered as relevant.

In recent years, more and more IP players started disclosing high number of generic inventions where the application scope is not limited to a single field of application (e.g., RF, power). This growing IP trend arose from IP players' adaptation strategy in the GaN electronics landscape, aiming to address different markets (power, RF) with a single technology platform (e.g., GaN-on-Si). Such generic inventions were categorized as "Not specified" and were analyzed in both power and RF GaN IP landscapes:

In the power GaN IP landscape, we analyzed all power GaN patents and generic GaN electronics patents from IP players owning power GaN patents, resulting in a corpus of more than 10,000 patent families (inventions).

In the RF GaN IP landscape, we analyzed all RF GaN patents and generic GaN electronics patents from IP players owning RF GaN patents, resulting in a corpus of more than 6,500 patent families (inventions).

Focus on national and regional IP strategies to address geopolitical uncertainties

The GaN electronics patenting activities from Japanese players in the 2000s and then from the Chinese players since 2015, have been massive. As such, they mask important IP trends occurring in other countries with significant market opportunities and stand-out companies advancing GaN technology. What's more, IP has become an important component in the adaption strategies of companies and countries to a geopolitical context that can cause volatility. This report unveils these new IP trends and IP strategies by providing a separated analysis of each national or regional ecosystems emerging for power and RF GaN technologies.

For each region are detailed: Time evolution of IP activities, Supply chain from a patent perspective, Status of players' IP activity, Most active IP players and new entrants, Main technical challenges addressed by IP players, IP strategies of players, Recent IP collaborations and IP transfers, an Key players' patent portfolio.



In-depth analysis of the global IP competition across the power and RF GaN supply chains

Generally, IP strategies should focus on what a company has identified as most critical to impact the power and RF GaN markets, in terms of logistics (supply), technology (barriers), volatility (regulations, geopolitics) and economics (costs, margins). Accordingly, IP competition analysis should reflect the vision of players with a strategy to enter and develop their business in the power and RF GaN markets. Interestingly, new players looking to a vertical integration strategy may be identified based on their patenting activity, expanding into new parts of the supply chain.


What's more, such strategies may leverage different partnerships and acquisitions that involve the IP of other players and that have important implications for the complete ecosystem. This report unveils the IP strategies of main players in the GaN electronics landscape and the potential implications of acquisitions and partnerships between the GaN electronics IP players, leveraging a combined market, supply chain and technology-based analysis.

For each segment of the supply chain are detailed: Time evolution of IP activities, Main patent assignees, most active IP players, and new entrants, IP leadership, Current legal status of their patents, Technical challenges addressed by IP players, Main patent assignees and new entrant by technical challenge.

As the competition grows in the power and RF markets, players may leverage their IP to assert their market position, providing that they have built strong patent portfolios in strategic IP spaces of the technology. The report aims to identify such strategic IP spaces based on the analysis of the IP competition related to critical aspects of the technology. For instance, the realization of e-mode transistors has been a critical issue for the commercialization of GaN technology in power applications. In the GaN Electronics Patent Landscape report, this is one of the most competitive IP space that has been identified in the power GaN supply chain.

Recently, e-mode GaN patents have been at the center of a US-China patent dispute between two of the main IP players in the power GaN patent landscape. EPC is a well-established IP player in this space, while Innoscience is one of the main IP challengers. Such dispute reminds the threat represented by the IP of tiers companies in a particular geopolitical and economic context. It should support the establishment of more IP licensing agreements and partnerships between GaN electronics IP players in the next few years. The report details the complex relationships between GaN electronics IP players (patent co-filings, patent transfers and patent litigations).

Useful Excel patent database

This report also includes an extensive Excel database with the 15,000+ patent families (inventions) analyzed in this study. This useful patent database allows for multi-criteria searches and includes patent publication numbers, hyperlinks to an updated online database (original documents, legal status, etc.), priority date, title, abstract, patent assignees, patent's current legal status, and segments (wafers and epiwafers, devices, packaging and modules, circuits and applications, current collapse, e-mode transistor, GaN-on-Si, etc.).

  • New companies have entered the power GaN market recently or announced their intention to enter this market shortly.
  • Early market players look to consolidate their leadership amid growing competition worldwide and geopolitical tensions escalating between US and China.
  • As a countermeasure to US trade sanctions, China is driving the development of a domestic supply chain to serve its own market.

RF GaN

  • The RF GaN industry landscape has been reshaped by acquisitions and partnerships (IP, manufacturing) between well-established players in the RF industry.
  • The deployment of 5G base stations is driving the RF GaN market, with GaN-on-SiC RF devices progressively replacing Si LDMOS in the telecom infrastructure.
  • There is a growing interest for RF GaN-on-Si devices as the telecom infrastructure evolves toward lower power and higher frequencies (e.g., 6G applications).
  • The opportunity to offer RF GaN technology at lower cost by leveraging the existing Si manufacturing lines and the GaN-on-Si platform is expected to drive the emergence of new players in the RF GaN market.
  • RF GaN-on-Si technology is now close to enter the market. Yet many technical challenges remain to be solved for the large-scale adoption of the RF GaN-on-Si platform (incl. reliability, process maturity and scalability).
  • Regardless of the platform, innovations at all levels - from epitaxy to devices, packaging and circuits - are still strongly required to fully unlock the potential of GaN technology in RF applications.
  • In the field of telecommunications, US government has recently banned new equipment from Chinese players such as Huawei and ZTE, citing national security risk.
