+As can be seen in [recent news](https://www.datanami.com/2023/10/16/cloudera-hit-with-240-million-judgement-over-erasure-coding/)
+there has been lawsuits related to possible patents of aspects of erasure coding functionality.
+
+As a possible mitigation it is possible to use the tag `nopshufb` when compiling any code which includes this package.
+This will remove all inclusion and use of `PSHUFB` and equivalent on other platforms.
+
+This is done by adding `-tags=nopshufb` to `go build` and similar commands that produce binary output.
+
+As already stated using the above *may* result in non-infringing code.
