Update on US and European Patent Applications
Bondholders’ Meeting
Quantum Blockchain Technologies (AIM: QBT), the AIM listed investment company,
announces that it has written to the holders of the Company’s Zero-Coupon Bonds
(ISIN XS0891139031), originally issued in 2013 and most recently amended at the
Bondholders’ meeting held on 22 February 2024 (the «Bonds»), calling a meeting
to seek Bondholders’ approval of the following proposals (the «Proposals»);
– to extend the maturity of the Bonds from 15 December 2026 to 15
December 2028;
– to amend certain terms of the Bondholders’ conversion right,
modifying the conversion price from £0.03 to £0.02; and
– to remove the terms regarding the redemption of the Bonds at the
option of the Bondholders on a de-listing;
All Bondholders are entitled to vote on the Proposals. Eufingest SA, which holds
62.5% of the Bonds, has confirmed to the Company that it intends to vote in
favour of the Proposals. The current total face value of the Bonds is €5.5m.
The meeting will be held at 10.00 a.m. (GMT) on Wednesday 15 April 2026 at the
Company’s registered office, First Floor, 1 Chancery Lane, London, England, WC2A
1LF.
The Bondholders’ meeting requires a quorum of two Bondholders holding at least
66.66 per cent of the Bonds. If the meeting is inquorate, it will be adjourned
for 14 days. At any adjourned meeting, any number of Bondholders will represent
a valid quorum. Bondholders who wish to vote and whose Bonds are held in the
name of a broker, dealer, commercial bank, trust company or other nominee
institution (including as CDIs) must contact such nominee promptly and instruct
or make arrangements with such nominee to vote in accordance with the customary
procedures of the clearing systems on behalf of the bondholders. Proxies are due
no later than 10.00 a.m. (GMT) on Monday 13 April 2026.
US Patent Application – ASIC Ultra Boost
Further to the Company’s announcement of 5 March 2026, QBT has been informed
that its US patent application for ASIC Ultra Boost (US Patent Application No.
18/696,073) has received a «Final Rejection» from the United States Patent and
Trademark Office (USPTO). This is despite an amended set of patent claims (which
define the scope of legal protection) having previously been agreed to by the US
patent examiner. The US patent examiner has since conducted further searches and
has now raised an objection based on a newly cited document, which has still to
be considered by QBT’s team.
Although the rejection is classified as «Final», this does not mean that the US
patent application for ASIC Ultra Boost will ultimately be refused by the USPTO
since there is still an opportunity to review and respond to the rejection. QBT
will be working with its Patent Attorney to review the Final Rejection and newly
cited document in detail with a view to formulating a robust response, as well
as consider presenting further arguments and/or amended claims by discussing the
application further with the US patent examiner. The issuance of a «Final
Rejection» is also a very normal occurrence in the US patent application process
that can often be overcome.
The Company stresses that the US patent application will have no negative impact
on the progress it is currently making with the two tests it is conducting on
the software version of its Method C AI Oracle which does not need to be
protected by a patent at this time.
European Patent Application – Message Schedule Arrays
The Company further announces that its European patent application titled
«Message Schedule Arrays» was published by the European Patent Office on 18
March 2026 under publication number EP 4710505.
The publication of this application marks an important milestone, as it provides
the Company with provisional protection across European Patent Convention
contracting states and enhances the visibility of its proprietary technology in
advanced cryptographic processing.
The invention relates to novel methods for improving computational efficiency in
hashing processes, which may have potential applications in blockchain and high
-performance computing environments.
The Company continues to actively progress its patent portfolio and will provide
further updates in due course.
This announcement contains inside information for the purposes of Article 7 of
the Market Abuse Regulation (EU) 596/2014 as it forms part of UK domestic law by
virtue of the European Union (Withdrawal) Act 2018 («MAR»), and is disclosed in
accordance with the Company’s obligations under Article 17 of MAR.
