Why apply for a patent?
A patent can get you a better market position. You can avoid price competition in those markets where you have patent protection.
You also force other actors to develop their own technical solutions to the problem that your invention solved.
A patent is an intangible asset. The rights to a patent can be bought, sold or licensed. A patent can also make it easier to attract investors or sell your company. A business partner who gains access to protected technology can be prepared to pay more for what you have to offer.
You can get information about how an invention can be turned into a finished product, or used as a competitive advantage, from the same innovation actors who can help you with company formation and entrepreneurship.
