If I sold my invention to a company, can I create a new version based on it?
<p>Let's consider I have created a new robot it cleans the windows. A company gives me a tons! of money and I will sell it to the company and say goodbye and completely leave the project. Then after some months I have a good idea to improve the robot, or like to create a new robot based on it, or very similar to it, What do should I do? What the law is in this situation?</p>

<p>Can I do mass production of new version by myself?</p>

<h2>What does your contract say?</h2>

<p>What it permits, you can do. What it prohibits, you can’t. What it’s ambiguous about you get to go to court and fight over.</p>

<p>You may be able to patent the new improvement to the robot, either alone for the improvement or as a whole robot that includes the improvement, so long as it is novel and a non-obvious improvement over the existing patent/robot.  </p>

<p>However, you probably can't sell or use the new robot without a license to your own prior invention because your new robot almost certainly includes the patented invention related to the original robot.  Thus, the patent on your robot improvement blocks your prior company from using that improvement, but doesn't allow you to practice the new invention unless you can design around the patent(s) related to the original robot or you can get a license to those patents. </p>
