In India as per the Patent Act of 1970, You cannot patent an idea for an invention. The invention itself has to be produced or a patent application containing the invention must be filed with the Indian Patent Office. In order for him to protect his invention he needs to be the first one to file for its patent or else if someone steals it he won’t be able to file a case on him. A person who has merely communicated the idea to another, who actually gave practical shape to the idea and developed the invention, cannot claim to be the first and true inventor. So your friends should file a patent application as soon as possible.
