Sounds like someone needs to develop a permissive open-source license
for which the main change is that it explicitly disallows the use of
it in a patent.
Ex: MIT + can't be mentioned in patent clause
Sure this would change the patent to "label printer using Lua" to
"label printer using scripting language"... but at least that should
be generic enough to be thrown out, or at least more easily fought
using prior art (ex: post-script on printer).
