A recent Patent Trial and Appeal Board decision related to hybrid quantum computing paves the way for more quantum computing-related patents, and potential litigation.
Quantum computing is an important and evolving form of computing that has yet to be truly realized. Classical computing is, fundamentally, governed by the ability to store information in a bit, a binary unit represented by a one or a zero. In contrast, quantum computing is governed by a quantum bit, or qubit, which can represent an infinite, continuous number of possible states. For example, while 2 bits can store four combinations (00, 01, 10, or 11), 2 qubits can store all four combinations simultaneously. Hybrid quantum-classical computing (“HQC”) involves using both quantum computing and classical computing together in a system for one to address the shortcomings of the other. At its core, both types of computing are well known and rely on mathematical concepts making patent claims on a HQC highly susceptible to patent ineligibility attacks.
