Update on US Patent Application

Quantum Blockchain Technologies Plc's US patent application (US Patent Application No. 18/696,073) for 'ASIC Ultra Boost' received a 'Final Rejection' from the USPTO; the company also received a detailed report from its US patent attorneys. This is a setback for QBT's IP protection and could limit exclusive commercialization of the ASIC Ultra Boost technology; no financial impact, remedies or next-step timeline were disclosed. The company previously announced developments on 23 March 2026 and will review attorney recommendations before determining further action.

Analysis

The USPTO final rejection materially weakens QBT's pathway to recurring licensing or defensive-enforcement revenue, turning a previously prospective, high-margin optionality into a financing and execution risk. For a subscale AIM issuer, loss of a credible IP moat compresses exit options (licensing, litigation settlement, or acquisition) and raises the probability of a distressed-equity re-rating within weeks to months as funding cycles tighten.

Competitively, incumbents that already own ASIC design portfolios or trade-secret positions (large mining-hardware suppliers and established semiconductor IP owners) gain by default — they face one fewer potential challenger and see lower near-term threat of price-disrupting licensing suits. Second-order, miners and cloud-mining service providers face little direct change to supply economics, but the pool of potential buyers for differentiated ASIC technology narrows, making M&A a more likely consolidation lever for the next 6–18 months.

Key catalysts and tail risks are asymmetric in time: near-term downside is driven by market psychology and funding stress (days–months), while redemption hinges on USPTO appeals, continuations or claim amendments (months–2+ years). A timely filing of a continuation or allowance after claim narrowing could produce sharp short-covering; conversely, protracted finality or adverse precedent would likely extinguish material IP value and invite creditor/board action. Monitor filings and prosecution milestones — these are the binary gates that will determine whether this is a liquidity/PR event or a structural loss of IP value.

Key Decisions for Investors

• Reduce/close long exposure to QBT.L within 1–4 weeks; if unable to exit, hedge 50–75% of position by buying 6–12 month protective puts (strike ~10–20% below current price). Rationale: small-cap funding squeeze and reputational hit create elevated short-term downside; hedge cost is a rational premium against a potential binary loss of IP monetization.
• Event-driven short: initiate a tactical short of QBT.L sized no more than 2–3% of portfolio NAV, targeting 30–50% downside over 1–3 months with a 10–15% stop-loss. Trade mechanics assume continued negative market reaction and limited near-term catalysts for reversal absent a filed continuation or examiner interview.
• Contrarian asymmetric long: if you want asymmetric upside, buy a small position in 9–12 month deep-ITM or near-ITM call structure (or call spread to cap premium) only after management publicly files an appeal/continuation. Risk is total premium; reward is 3–5x if prosecution reverses or if an acquirer pays up within 6–18 months.
• Set monitoring triggers (no position): track USPTO docket for Notice of Appeal, continuation filing, or examiner interview within the next 90–360 days. If a continuation is filed, move to buy calls or add long equity size; if prosecution is abandoned, exit any remaining long exposure immediately and redeploy capital.
