Quantum Blockchain Technologies PLC (AIM:QBT, FRA:BYA1) CEO Francesco Gardin talked with Proactive's Stephen Gunnion about the company’s latest progress surrounding its patent portfolio and the potential impact of its ASIC Ultraboost technology on Bitcoin mining efficiency.

During the interview, Gardin explained how patent applications can already be used by a company even before they are formally granted. He noted that once an invention is filed, companies can develop products around the technology and mark them as “patent pending,” which signals to competitors that copying the idea could lead to infringement if the patent is eventually granted.

The discussion also focused on the importance of the United States market, which Gardin described as the largest market for Bitcoin mining. Quantum Blockchain Technologies currently has its ASIC Ultraboost patent application in the final stage of examination in the US, a key step in the patent approval process.

Gardin highlighted that discussions with patent examiners over the wording of claims represent an important milestone, although approval is not guaranteed.

Gardin outlined how ASIC chip manufacturers have historically improved performance by shrinking chip sizes to increasingly smaller nanometer scales. However, he pointed out that there are limits to how far this approach can go. QBT is instead targeting algorithmic improvements to the SHA-256 hashing process, which underpins Bitcoin mining. According to Gardin, the company’s approach could deliver an efficiency improvement of between 8% and 12%, a potentially meaningful advantage in a highly competitive sector.

He also noted that Quantum Blockchain Technologies continues to develop additional intellectual property through its team of researchers as part of its ongoing R&D activities.
