Does DMCA applies on decompiled assets from apk
<p>Actually this question ( <a href="https://law.stackexchange.com/questions/32630/does-dmca-cover-apps">Does DMCA cover apps?</a> ) does not cover my answer. Actually I have made an android app which is published on play store. I had trained some machine learning models which I used in my app and they were present in my apk. Recently I realized that some developer from China has decompiled my apk and used my machine learning models in their app. But cleverly they modified my models content with some fake data, and on runtime they put the right data within the model to make them work. I cannot access the right data to make the model work because it is encrypted in c++ files. </p>

<p>I am wondering is there any way I can file DMCA take down notice against the developer. Or it is considered the "Fair use" in terms of DMCA ( I am new to this act ). Please help me.</p>

<p>Thanks </p>

<p>Your software is protected by copyright: decompiling, fiddling with, and redistributing your software is infringement. If they published their product e.g. with Google, then you can file a DMCA takedown notice, with the host service. At that point, Google will take the item down; the other party may or may not file a counter-notice (claiming that they have the right to distribute the material), and if they do, Google will notify you. Then you have to notify Google that you are suing the other party (there is a 14 day outer window for this), at which point if you did your part, Google has taken the item down and you resolve this in court.</p>

<p>It is only when you get to court that the factual question of whether this is actually infringement is asked and answered. If you have a clever NOOP signature in the code which they didn't manually remove, you should win. The burden is on you to show that they copied your software.</p>
