I have a business plan for selling apparel over the Internet, with unique features that distinguish this idea from other sites. Before patenting this idea in the WIPO, can I tell about particularities with the investor, or is that a mistake?
You must avoid public disclosure of your idea before filing a patent application. The usual method of doing this when talking to potential investors is a confidentiality agreement. Have a confidentiality agreement drafted and have both parties sign before disclosure.
