Quantum Computing Patents: Who’s Leading the Race?
Imagine a computer so powerful it could solve problems in seconds that would take today’s fastest supercomputers thousands of years. This isn’t science fiction—it’s quantum computing, and right now, there’s a global race to develop and patent this revolutionary technology.
As a patent agent who has worked with various tech companies on their intellectual property strategies, I’ve had a front-row seat to this fascinating competition. The quantum computing patent landscape reveals not just who might dominate this emerging field, but also where the technology is headed.
Why Quantum Computing Patents Matter
Before diving into who’s leading the patent race, let’s talk about why these patents are so important. Quantum computing isn’t just an upgrade to existing technology—it represents a fundamentally new approach to processing information.
Traditional computers use bits (0s and 1s) to process information. Quantum computers use quantum bits, or “qubits,” which can exist in multiple states simultaneously thanks to the weird properties of quantum mechanics. This allows quantum computers to tackle certain problems far more efficiently than conventional computers ever could.
The potential applications are enormous:
- Breaking currently unbreakable encryption
- Discovering new medications and materials
- Optimizing complex systems like global supply chains
- Revolutionizing artificial intelligence
- Modeling climate change with unprecedented accuracy
Companies and countries that control key quantum computing patents could potentially:
- License the technology to others for substantial fees
- Develop exclusive quantum-powered products and services
- Gain strategic advantages in both business and national security
As one CEO told me, “Whoever wins the quantum patent race won’t just lead a market—they’ll create entirely new markets.”

The David vs. Goliath Story
One of the most interesting aspects of the quantum patent landscape is the competition between established tech giants and specialized quantum startups.
The Tech Giants’ Advantage
Large companies like IBM, Google, and Microsoft bring enormous resources to the quantum race:
- Billions in R&D funding
- Decades of patent experience
- Large teams of quantum physicists and engineers
- Complementary technologies in computing, materials, and manufacturing
A patent attorney I worked with at one of these companies told me, “We’re not just patenting the quantum technology we need today—we’re trying to patent the approaches we might need in five or ten years.”
The Startup Innovation Edge
Despite the resources of the giants, quantum startups have some unique advantages:
- Focused, specialized teams without legacy business concerns
- Agility to pursue novel approaches
- Often founded by pioneering quantum researchers
- Strategic patent portfolios targeting specific quantum niches
One quantum startup founder shared with me, “We can’t file as many patents as IBM, but we can make sure the patents we do file are right at the heart of the technology we’re building our business around.”
This David vs. Goliath dynamic creates an interesting patent landscape where startups often hold key patents in specific areas while large companies build broader, more comprehensive portfolios.
The Patent Strategy Game
Companies are using different strategies in the quantum patent race:
The “Fundamental Blocker” Strategy
Some companies focus on patenting fundamental technologies that others might need to use:
Example: IBM has patents covering basic aspects of superconducting qubit design that could potentially affect anyone building this type of quantum computer.
The “Application-Specific” Strategy
Other companies focus less on fundamental quantum technology and more on specific applications:
Example: JPMorgan Chase has filed patents specifically for quantum computing applications in financial modeling and trading strategies.
The “Surrounding” Strategy
This involves filing numerous patents around a competitor’s key technology:
Example: Several companies have filed patents on technologies surrounding Google’s quantum supremacy approach, potentially limiting how Google can extend this technology.
The “Freedom to Operate” Strategy
Some companies file patents defensively, ensuring they can use their own innovations:
Example: Smaller quantum startups often focus on patenting their specific implementation rather than trying to patent broader concepts.
Challenges in Quantum Patenting
Patenting quantum computing technology isn’t straightforward. Several unique challenges exist:
1. Abstraction Problems
Quantum computing often involves mathematical concepts and physical principles that may be considered too abstract to patent in some jurisdictions.
A patent examiner once told me, “The line between an unpatentable scientific principle and a patentable application of that principle is particularly blurry in quantum computing.”
2. Disclosure Without Understanding
The requirement to fully disclose how an invention works creates challenges when the underlying quantum mechanics isn’t fully understood.
3. Prior Academic Publication
Many quantum innovations come from academic researchers who publish their work before considering patents, potentially invalidating future patent claims.
4. International Variation
Different countries have different standards for what quantum technologies can be patented, creating a complex global landscape.
The Future of Quantum Patents
Where is the quantum patent race headed? Several trends are emerging:
