I had a poster presentation on my research last month. Did I lose the patent rights?

Ideally, an invention disclosure should be completed and submitted to the Office of Innovation and Economic Development at least two months prior to any public disclosure of an invention to ensure sufficient time for an assessment of the technology to be completed and the preparation of a patent application (either provisional or non-provisional), if appropriate. Public disclosures include presentation at conferences, publicly available reports to funding sponsors, symposiums, publications, posts on social media, blog posts, posters and discussions with others outside the university without a non-disclosure agreement.
