Invention Disclosure

The following applies to the Inventions Policy. For information about the copyright policy, visit our Copyright Disclosure page.

Filing a disclosure is your first step towards commercialization at U of T. U of T has a flexible process that allows Inventors to take personal ownership and commercialize their invention on their own. Alternatively, you can offer ownership to U of T if you wish to take advantage of the commercialization services provided by U of T and MaRS Innovation (MI). In either situation, faculty have an obligation to disclose their inventions to U of T.

If the work that led to the invention was done at another institution (e.g. at one of the hospitals affiliated with U of T) or did not use any U of T resources, contact the appropriate hospital research office or the other institution’s technology transfer office.

If you believe that what you have developed does not fall under the Inventions Policy and wish to confirm, please fill out the Declaration of Invention with No Significant Use Form and submit it to the Intellectual Property Officer via email at

When to file a disclosure

Disclosures should be filed as soon as the invention or work can be clearly described in writing, has been reduced to practice, or if you want to publish a paper that may be considered prior art to your invention. You must disclose before you sell, license, or otherwise assign your invention.

File early so we have time to protect your intellectual property prior to public disclosure.

What to expect after disclosing

The Intellectual Property Officer will acknowledge receipt of your disclosure once a finalized copy has been received.

  1. If a research partner or sponsor has an option to license your invention, we will notify the partner that an invention has been made and await their response prior to additional action being taken.
  2. If there are no sponsor obligations and you request personal ownership, the Intellectual Property Officer will provide you with assignment documentation shortly after requested.
  3. If there are no partner obligations and the inventor wishes to assign the invention to U of T:
    1. A member of the Innovations team will assigned to perform an evaluation.
    2. An evaluation of the invention will be undertaken jointly with Mars Innovation (MI).
    3. A letter will be provided to advise if the project will be accepted either by MI or IPO and if not, explaining reasons for not accepting and perhaps suggesting additional work to refine the invention.

If the project is accepted into IPO and MI‘s portfolio, we will work with you during the entire commercialization process.
