Why my wife is looking at patent laws.

For many years my wife has been in the real estate business. Like everybody in her industry she uses the basic sign that she pushes into the ground. Since she is always wearing heals this has become a problem for her and the other women in her office. She got it into her mind that she wanted to design a better signpost. My wife knows nothing about global patent laws;however that is something she is going to learn about as she really wants to do this. She is even bringing in one of the women she works with into the equation.
