Is that in effect? Under what authority? It looks like a random webpage on debian.org without clear authorship or status. My perception is that there is a lot of patent encumbered code in Debian; for example the recent ML-KEM post-quantum crypto is covered by patents and licensed by NIST [1]. That Debian patent policy reads out of touch with todays reality IMHO. The defense against patent trolls in the FOSS world is today largely based on patent non-aggression patent protection like OIN. I like the mission of the above Debian patent policy, but either I misunderstand it or it seems entirely unenforceable today. In the policy manual, I only see: Packages must be placed in non-free if they are not compliant with the DFSG or are encumbered by patents or other legal issues that make their distribution problematic. That wording is confusing. It isn't clear which of the following intereprations are intented: Packages must be placed in non-free if they are (not compliant with the DFSG or are encumbered by patents) inclusive-or (other legal issues that make their distribution problematic). Packages must be placed in non-free if they are (not compliant with the DFSG or are encumbered by patents) exclusive-or (other legal issues that make their distribution problematic). Packages must be placed in non-free if they are not ((compliant with the DFSG or are encumbered by patents) inclusive-or (other legal issues that make their distribution problematic)). Packages must be placed in non-free if they are not ((compliant with the DFSG or are encumbered by patents) exclusive-or (other legal issues that make their distribution problematic)). Or something else. The first 'or' in the sentence could be read as inclusive-or or exclusive-or with different meanings too. /Simon [1] https://csrc.nist.gov/csrc/media/Projects/post-quantum-cryptography/documents/selected-algos-2022/nist-pqc-license-summary-and-excerpts.pdf
