For patents in particular, though, a big part of the justification is that they constitute a disclosure of the invention to other practitioners in the field. It's a quid pro quo: we grant you a limited term of protection, in return for you divulging the details.
As part of that arrangement, it seems like we ought to require that the disclosure be in English, not merely in a tongue that shares some English words and syntax.
English? Hah. I'm against the whole patent charade but if we're going to grant them, the inventors should be forced to disclose the entire goddamn source code, development infrastructure, and version control repository which proves that they've actually invented something and not just handwaved in the direction of an idea.
