In the text of the Artistic License 2.0 there is the following item at number 13:

(13) This license includes the license for worldwide, free-of-charge. Holder that are necessarily infringed by the Package. If you institute a patent litigation (including a claim or counterclaim), then you’ll have it.

And with the understanding of this item there are difficulties. Explain how to understand it correctly?

    To start the translation:

    (13) This license includes a non-exclusive, worldwide, free patent license to build, implement, use, offer to sell, sell, import and otherwise transfer the Package in relation to any patent claims licensed by the copyright owner that are necessarily violated by the Package. If you start a lawsuit against any party, claiming that the Package is a direct patent infringement or contributes to it, then the Artistic License in relation to you will expire on the date the claim is filed.

    The first sentence says that the copyright owner gives you a free right to use and sell the Package, as if to the detriment of his copyright, he simply shares it with you.

    The second sentence warns that if you start a lawsuit against someone regarding the infringement of anyone's patent rights in this Package, direct or indirect, you will lose all the rights granted by this license. Those. do not spit in the well from which you drink.

    PS Translation and interpretation of the free, comments and clarifications are welcome.
