What consitutes a look and feel which would not be considered a copy website or app?
<p>One can't copy a whole website or an app desgin, because it's copyright infringement.</p>
<p>But can one copy it to <em>some degree</em>, while making sure that a reasonable user wouldn't confuse it with the original?</p>
<ul>
<li>I'm referring to the &quot;confusing reasonable user&quot; concept, because this seems to be a main consideration for this kind of question, <a href="https://law.stackexchange.com/a/56829/41612">mentioned in an answer</a> of another question, and also in a <a href="https://stackapps.com/a/923/59842">related answer by Joel Spolsky</a> (of course, I'm asking a general question, this is not about SE).</li>
</ul>
<p>If so, what would constitute a design, look, and feel which would <em>not</em> be considered a copy website or app? Is it a question of a ratio (% of copied design)? Does placing disclaimers of &quot;this website is not related to that other website&quot; matter?</p>

<p>This concept is a test for <em>trademark</em> infringement, not copyright infringement.</p>

<p>It's a fact-specific analysis of the individual case.</p>
