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 $850B quantum computing market. 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 is far from settled, with corporate giants competing head to head against concentrated startup portfolios.

“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 Leadership
As 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.

About the Methodology
PatentVest’s analysis combined two complementary approaches. The IP landscape was built from its proprietary global patent database and includes 14,762 active families from 1,743 assignees worldwide, mapped across corporate, startup, and academic owners. In parallel, the benchmarking study evaluated 38 public and private quantum hardware companies developing superconducting, trapped-ion, neutral-atom, photonic, silicon-spin, and annealing systems. Each was assessed on technology focus, development progress, funding history, validation milestones, commercialization strategy, and patent defensibility.
