There are four factors that can impact a judge's ruling on copyright law. Which of the following is not one of them? the portion of the text you are wanting to use the effect on potential sales the purpose for using the copyright text the authenticity of the authorship of the work

## Step 1<br />The problem is asking us to identify which of the given options is not a factor that can impact a judge's ruling on copyright law. The options are: the portion of the text you are wanting to use, the effect on potential sales, the purpose for using the copyright text, and the authenticity of the authorship of the work.<br /><br />## Step 2<br />The first option, the portion of the text you are wanting to use, is a factor that can impact a judge's ruling on copyright law. This is because the amount of the text you want to use can determine whether it falls under the category of fair use or not.<br /><br />## Step 3<br />The second option, the effect on potential sales, is also a factor that can impact a judge's ruling on copyright law. This is because if the use of the copyrighted material could potentially harm the sales of the original work, it may be considered as not fair use.<br /><br />## Step 4<br />The third option, the purpose for using the copyright text, is another factor that can impact a judge's ruling on copyright law. This is because the purpose of the use can determine whether it is for commercial or non-commercial purposes, which can affect the ruling.<br /><br />## Step 5<br />The fourth option, the authenticity of the authorship of the work, is not a factor that can impact a judge's ruling on copyright law. This is because copyright law is concerned with the use of the work, not the authenticity of the authorship.
