I disclosed my invention with a patent attorney on my first free consultation to understand if it is patentable and get advice. The patent attorney told me that I can disclose it because they are legally bound to confidentiality because of their job. However we didn't sign anything yet and we had a remote video consultation due to the coronavirus lockdown.
I have registered the conversation, is that enough to protect my invention? Should I avoid disclosing my invention with patent attorneys on initial consultations next time?
