What I can say is that there is nothing significant to report in the latest update, we are still in a questions and answers phase, as we previously reported.
For internal reasons, on September 13, 2019, we submitted a "maintenance of applications" filing requesting more time before submitting a "written opinion".
Requesting a delay does trigger the issuance of new filling that states « Application deemed to be withdrawn (non-reply to Written Opinion) ». As we will submit the opinion before the end of the extension, this not issue.
For peoples not accustomed to the patent process, seeing such a comment may be seen as something negative, but as I have explained, it all part of the process.
Rest assured that before replying, I took the time to double-check with PyroGenesis and our Patent agent.
