Designed for investors, board members, and CEOs, the latest PatentVest Pulse Report reveals which companies are emerging as true leaders as quantum computing shifts from R&D to commercialization
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.”
