<p>Hello. I hope you can provide some advice on my situation.</p>
<p>This is a part of my employment contract. I have omitted the name of the company. My location is NJ.</p>
<p>I work as a cloud engineer. Recently I've been thinking about a particular app/business idea and I've been putting some time and effort into it outside of work (weekends, or in the evenings during the week).</p>
<p>Since I would eventually like to implement this idea as a website / web application and utilize cloud technology in doing so, could this mean my employer owns the idea and anything I develop --since I would use the same technology for my idea that I do at work? Even though it is completely and utterly unrelated to the business model of my employer and I have not used work hours in my implementation of this idea? Would this also mean that any open-source software I develop outside of work automatically belongs to my employer?</p>
<p>What is the extent and limitations of such a clause, which I have agreed to?</p>

<blockquote>
<p>could this mean my employer owns the idea and anything I develop --since I would use the same technology for my idea that I do at work?</p>
</blockquote>
<p>No, unless by &quot;technology&quot; you mean the employer's <em>materials</em> or resources (see condition 3 of the clause). Your remark that &quot;<em>this is completely and utterly unrelated to [employer's] business model</em>&quot; survives items 1 and 2. Likewise, working on your idea <em>outside hours</em> survives the corresponding part of item 3.</p>
<blockquote>
<p>Would this also mean that any open-source software I develop outside of work automatically belongs to my employer?</p>
</blockquote>
<p>No, unless the software you develop is &quot;<em>based on [your] knowledge [etc.] of (COMPANY)</em>&quot;.</p>
