quantum computing stocks ranking quantum players based on patent

PatentVest released the Quantum Computing Pulse Report ranking 38 companies in the $850B quantum computing market based on IP leadership. PatentVest has launched its Quantum Computing Pulse Report, the first comprehensive ranking of key players in the $850 billion quantum computing market, aimed at investors and business leaders. The report evaluates the progress of 38 companies in terms of their commercialization efforts, competitive benchmarks, and the strength of their intellectual property (IP), utilizing data from 14,762 patent families. Major companies like D-Wave, Origin Quantum, and IonQ have emerged as frontrunners in this highly contested space, while corporate giants such as IBM and Alphabet lead in patent publications. The report emphasizes that future success in quantum computing will hinge not just on funding and technological milestones, but critically on defensible IP and effective commercialization strategies. The full report is available for download on PatentVest’s website.

The Quantum Computing Pulse Report is the first-ever ranking of companies in the $850B quantum computing market, evaluating their IP strength and commercialization progress. The report profiles 38 companies worldwide that are advancing commercialization in the quantum computing sector. Factors include technology modality, funding and valuation history, patent portfolio defensibility, and commercialization progress. U.S. Quantum Computing Patent Leadership: In 2024, the U.S. led globally in quantum computing patents, with IBM and Alphabet significantly ahead of competitors, while Rigetti topped among pure-play quantum companies.

Market Growth Potential: The global quantum computing market is projected to grow from approximately $1.4 billion in 2024 to between $90 billion and $170 billion by 2040, indicating a compound annual growth rate of... Investment Insights: Monitoring patent activity is crucial for investors in emerging technologies, as patents provide a temporary monopoly on inventions, and companies like Nvidia are increasing their involvement in quantum computing. Patent Quality Metrics: The value of patents can vary, with citation frequency being a key metric; Northrop Grumman ranks high in U.S. quantum patents, while Nvidia has recently introduced products to enhance quantum-classical computing integration. Addison, TX, Aug. 19, 2025 (GLOBE NEWSWIRE) -- PatentVest, the first fully integrated IP intelligence and legal strategy firm, today announced the release of its Quantum Computing Pulse Report, the first-ever rankings of leadership in the emerging...

Designed for investors, board members, and CEOs, the report profiles 38 companies worldwide advancing commercialization through competitive benchmarking and maps the broader intellectual property landscape, drawing on 14,762 patent families to show that leadership... “Quantum computing has reached a historic inflection point,” said Will Rosellini, Chief IP Officer at PatentVest. “What was once pure R&D is now shifting into commercialization, and the winners of this race will own the future. With billions in venture capital already flowing in and public companies trading at multi-billion-dollar valuations, the stakes have never been higher. That’s why this report evaluates both competitive progress and IP defensibility to separate signal from noise and show who is truly positioned to lead.” Competitive Benchmarking: The Top Companies Racing Toward LeadershipAs part of the analysis, PatentVest evaluated 38 companies across technology modality, validation milestones, funding and valuation history, commercialization progress, and the defensibility of their patent portfolios.

Emerging Quantum Computing Companies Ranked by Global Patent Publications with Total Patent Families (2025) The results show a highly concentrated leadership group. D-Wave, Origin Quantum, and IonQ stand out as frontrunners, while heavily funded challengers such as PsiQuantum, Quantinuum, and IQM continue to push forward aggressively. Daily stocks & crypto headlines, free to your inbox By continuing, I agree to the Market Data Terms of Service and Privacy Statement Quantum computing is no longer just a scientific curiosity—it is a fiercely competitive industry where companies and countries are racing to secure patents that will define the future of computing.

Patents in quantum computing are critical because they give companies exclusive rights to revolutionary technologies, ensuring dominance in this emerging field. IBM has been at the forefront of quantum computing for decades, and their dominance in patent filings proves their commitment to staying ahead. Their portfolio covers everything from superconducting qubits to error correction, quantum algorithms, and even hardware optimization. What makes IBM’s strategy so effective? They are not just filing patents—they are making sure their patents have real-world applications. By investing in open-source quantum computing tools like Qiskit, they allow researchers to experiment while keeping key technologies under patent protection.

Actionable Insight: If you are a startup or researcher, study IBM’s patenting strategy. Look at how they balance open-source contributions with patent protections. Companies can also leverage IBM’s open-source tools to develop new applications without infringing on their patents. Google’s biggest breakthrough came in 2019 when they claimed quantum supremacy. Since then, their focus has been on refining superconducting qubits and improving quantum error correction—two areas crucial for making quantum computers practical.

IBM leads the pack in terms of the average number of forward citations per U.S quantum patent, indicating the high quality and impact of its patents in the quantum computing space. Alphabet and Microsoft also have significant average citation numbers, showcasing the importance of their contributions to the field. Investors interested in quantum computing should keep a close eye on patent activity to gauge the innovation and competitiveness of companies in this space. The number and quality of patents can provide valuable insights into the future growth and success of quantum computing companies. **In summary, the blog discusses the top companies with the most U.S. quantum computing patents in 2024, the projected growth of the quantum computing market, and the importance of monitoring patent activity for investors in the tech sector.

It highlights the key players in the quantum computing field and provides insights into the quality and impact of their patents.** The quantum computing industry is experiencing significant growth, with IBM, Alphabet, and Microsoft leading the way in U.S. quantum computing patents awarded in 2024. Quantum computers have the potential to revolutionize problem-solving by encoding data in qubits, allowing for complex calculations that classical computers struggle with. The global quantum computing market is projected to reach substantial values by 2040, attracting investors eager to capitalize on this emerging technology.
