Information that is published or generally accessible to the public (for example, through a conference or webinar) is considered in the public domain or publicly available and not subject to export control regulations. However, you should ensure that the webinar is indeed open to the public, such that all technically qualified members of the public are eligible to attend, and that attendees are permitted to take notes or otherwise make a personal record (not necessarily a recording) of the proceedings and presentations. A registration fee may be charged if it is reasonably related to the cost of putting on the conference, and reflects an intention that all interested and technically qualified persons be able to attend. However, you may limit actual attendance, as long as attendees either are the first who have applied or are selected on the basis of relevant scientific or technical competence, experience, or responsibility.

Evaluation is case-specific; thus, it is recommended that you contact the Export Control Office to review your circumstances.
