In the Status column of the above table, ‘Pending’ means that the examination is still ongoing, as is the case of the US patent application for ASIC Ultra Boost. In this particular case, the agreed wording for each patent’s claims, which legally define the scope of protection sought for the invention, has been agreed with the US Patent Office & Trademark (“USPTO”) examiner, which generally indicates a positive final stage of the examination process.

As also stated in the table, QBT has abandoned its initial UK applications in favour of patent applications filed under the European Patent Convention (“EP”), which covers 39 European countries, including the UK.

Francesco Gardin, CEO and Executive Chairman of QBT, commented , “The approval process of patent applications can be a long one, which could take many years. However, being granted a patent for a new product is the only option if one wishes to build and then protect an IP portfolio with inventions. As previously confirmed to the market, some of QBT’s technology will remain an industrial trade secret, while other inventions will be protected via patents. A number of factors are being considered by the Company for each of its software innovations in order to best protect our intellectual property.”
