Open Source Licensing
summary
Covers concrete licensing outcomes: GNU Radio out-of-tree modules do not automatically become GPL until conveyed with GNU Radio, GPLv3 patent grant prevents upstream patent traps, U.S. courts cannot force release of source only require stopping infringement, and copyright assignment grants a license back so contributed code can still be reused commercially. Flags unresolved areas: FPGA/HDL licensing is ambiguous in U.S. law and CERN is drafting an Open Hardware License v2 family aimed at ASIC/FPGA boundaries.
