# Guides

How design patents affect product sellers, and what to do about them. Each guide works without DesignAround and names the laws and official sources it relies on.

### [How to check a product for design patents before you sell it](https://designaround.elidot.com/guides/check-design-patents-before-selling/)

Where to search in the US, China and the EU, how to compare the closest designs the way an ordinary observer would, and which designs no search can find yet.

### [What to do when Amazon removes a listing for a design patent complaint](https://designaround.elidot.com/guides/amazon-design-patent-complaint/)

Why APEX does not apply to design patents, the ways a listing comes back, and the 21-day answer deadline in a Schedule A lawsuit.

### [How to design around a design patent](https://designaround.elidot.com/guides/design-around-a-design-patent/)

Which changes make a product look different to an ordinary observer, which common changes do not help, and how to protect the new design.

### [Design patent drawing requirements in the US, China and the EU](https://designaround.elidot.com/guides/design-patent-drawing-requirements/)

Views, lines, shading, broken lines, file formats, fees and terms for USPTO, CNIPA and EUIPO applications, side by side.

### [中文指南](https://designaround.elidot.com/zh/guides/)

The same four guides in Chinese.

### [Changelog](https://designaround.elidot.com/changelog/)

What changed in the DesignAround app, the service and these pages.
