Blanket patent licences and promises

A blanket licence is when a company gives a certain group of users/developers protection from all their patents. A fairly good example is Red Hat's promise not to use patents against free software users and developers. slashdot.org Other companies have made narrower promises that only grant protection from a small portion of their patent portfolio. Some promises are so narrow, they're probably useless and were probably just a publicity stunt.


[edit] What's good and bad

  • A "licence" is better than a "promise" or a "pledge". A "licence" has a solid definition and has been tested repeatedly in courts.
  • It's good when a licence (or promise) covers a company's entire patent portfolio, like Red Hat's.
  • It's bad when it only covers a selection, like Google's March 2013 pledge about 10 patents (from a company with 18,000 patents[1]).

[edit] Examples of company patent promises

Note: these are not examples of good promises, it's just a list which might be informative or which might help explain the issues involved.
