EPO Patent Insight Report on Quantum Simulation
Comprehensive Analysis
November 15, 2023
Objective
The report aims to provide an overview of significant patent trends in 2G quantum simulation technologies.
Methodology
Conducted by subject-matter specialists and patent knowledge experts at the EPO, the analysis uses publicly
available patent information from EPO’s databases. This information is vital for understanding inventions’
technical and commercial aspects.
Chapter 1
Key Findings
1.1 Growth in Patents
The number of inventions in 2G quantum simulation has dynamically increased over the last decade, surpassing
the growth rate observed across all technology fields. This surge suggests strong commercial expectations
and a shift toward multinational commercialization strategies.
1.2 Active Patent Applicants
Predominantly companies in the United States, followed by Canada, Europe, China, and Japan, are the most
active patent applicants. Notable entities include Google, IBM, Microsoft, the University of Maryland, and
Harvard University. The recent years show a realignment in research and development activities within this
field.
Chapter 2
Quantum Simulation vs. Quantum Computing
2.1 Differences in Operation
Unlike quantum computers, quantum simulators do not require intervention during their operation. They
are less complex in managing coherence problems and are capable of simulating the physical and chemical
properties of complex structures and compounds, potentially leading to new products and applications in
various scientific fields.
Chapter 3
Methodology and Sources of Patent Information
3.1 Patents as Legal Rights and Commercial Assets
Patents foster innovation, technology diffusion, and economic growth. They allow patent holders to secure
investments in R&D and infrastructure while mandating the disclosure of inventions to the public.
3.2 Patent Information as a Resource
With over 140 million patent documents from more than 100 countries, EPO’s databases provide a wealth
of technical and other information. This data is essential for exploring technical trends, applicant filing
strategies, and innovation activities.
3.3 Methodological Approach
The report’s methodology involves creating and refining a basic data set, analyzing patent data, and visualizing
the results. This process is designed to be adaptable for tracking trends and developments in various
technical fields.
Chapter 4
Patent Classification and Data Sources
4.1 Classification Systems
The International Patent Classification (IPC) and Cooperative Patent Classification (CPC) systems categorize
the technical subject-matter of patents. These systems, with their hierarchical structure, help in
efficiently retrieving relevant patent documents.
4.2 Data Sources and Tools
The analysis relies on EPO worldwide patent data and uses internal data platforms and search interfaces like
ANSERA. The PATSTAT product line also provides added value data for advanced analysis.
Chapter 5
Analysis of Filing Trends
5.1 Rising Number of Patent Applications
The number of patent applications in 2G quantum simulation has increased significantly, particularly from
around 2017. This trend is higher than the general increase in inventions across all technology fields. A
decrease observed in 2021 may be due to incomplete data or specific conditions of International patent
applications.
5.2 Patent Application Routes
Applicants have focused on International, US, JP, EP, CN, and CA applications, with a notable emphasis
on the US market. This trend indicates high economic expectations and multinational commercialization
strategies.
Chapter 6
Geographic and Collaborative Trends
6.1 Strategic Orientation and Success
The US leads in granted IP rights for quantum simulation, followed by Japan, Australia, China, and Europe.
The European Patent Convention provides a unified application procedure for patent protection in Europe,
affecting the representation of International Patent Families in the report.
6.2 Active Patent Applicants and Collaboration
Collaboration is evident mainly between research institutions and between companies and academic institutions,
both within the same country and across national borders. Notable examples include collaborations
between US companies and universities and between applicants in the US and Japan.
Chapter 7
Conclusion and Future Outlook
The EPO Patent Insight Report on Quantum Simulation offers a detailed analysis of the current state and
trends in the field of 2G quantum simulation. It highlights the growing significance of this technology,
key players involved, and the strategic importance of patenting activities in shaping the future of quantum
simulation. The report’s comprehensive methodology and extensive use of patent data make it a valuable
resource for understanding the dynamic landscape of quantum simulation technologies.
