Free software
From en.swpat.org
Free software is software which can be used, copied, redistributed, and whose source code can be viewed, modified, and also redistributed. See also:
"Free software" is not a subtopic of software patents. Development and distribution of all types of software carry the risk of patent infringement. The reason these two topics often appear together is that, firstly, the free software community is very active and vocal in campaigning against software patents, and secondly, software patents threaten a general freedom that free software users value: the freedom to participate in software development.
The term open source is a near-synonym. Patents affect the freedom that users and developers have when dealing with software. Patents don't affect "openness", so en.swpat.org should use the term "free software".

Why free software groups should be involved
The free software movement says that everyone should be allowed to modify and redistribute the software they use. Software patents interfere with this because they can add legal risks and costs to software development and distribution.
How patents effect free software
Free software has some advantages:
- The development models are more distributed, so there's often no single big company behind a software package. This means there are fewer tempting targets for patent trolls
- If a patent holder makes a threat, anyone can remove that one feature from free software packages. The patent holder could still sue for past damages, but could not force the package to be entirely removed from the market, and the continued use of that patented idea is a decision that can be made by the users, not by making a deal with a single distributor.
Free software also has certain difficulties:
- Many patent licensing agreements are structured in a way that excludes free software. If there is a per-copy fee, even if the amount is miniscule, there's no way to comply with this requirement because distributors can't know how many copies the users will make.
Patent promises in 2005
IBM promised, for 500 of its patents, not to use them against free software.[1]
Sun[2] and Nokia[3] subsequently made promises that were so narrow in scope, they were qualified as "empty" and "next to nothing", respectively, by Richard Stallman.[4]
