+1.
You should probably consider accepting code that involves patents that
are in the public domain or expired by the time of release, though even
that involves some legal costs you might not want to incur. E.g., what
if a US patent is in the public domain but a corresponding EU patent is
not? A search could be done, naturally, but professional patent
searches are not cheap!
