Can I discuss the details of my invention with a potential investor before filing a patent application?

It is important to file a patent application before publicly disclosing the details of the invention. In general, any invention which is made public before an application is filed would be considered prior art (although the definition of the term "prior art" is not unified at the international level, in many countries, it consists of any information which has been made available to the public anywhere in the world by written or oral disclosure). In countries which apply the above definition of the term "prior art", the applicant's public disclosure of the invention prior to filing a patent application would prevent him/her from obtaining a valid patent for that invention, since such invention would not comply with the novelty requirement. Some countries, however, allow for a grace period, which provides a safeguard for applicants who disclosed their inventions before filing a patent application, and the novelty criteria may be interpreted differently depending on the applicable law.

If it is inevitable to disclose your invention to, for example, a potential investor or a business partner, before filing a patent application, such a disclosure should be accompanied by a confidentiality agreement.
