Enablement Challenges in Quantum Computing Patents: Lessons from Recent PTAB Cases

The quantum computing revolution is generating groundbreaking innovations – and equally complex patent prosecution challenges. Among these challenges, enablement requirements under 35 U.S.C. § 112(a) have emerged as a particularly thorny issue for patent practitioners working in this field.
