I'm using bumptech/glide for loading images in my app.

After reading the License i saw that most of the library was licensed under the Apache License except for the AnimatedGifEncoder.

License for third_party/gif_encoder/AnimatedGifEncoder.java and third_party/gif_encoder/LZWEncoder.java:

No copyright asserted on the source code of this class. May be used for any purpose, however, refer to the Unisys LZW patent for restrictions on use of the associated LZWEncoder class. Please forward any corrections to [email protected].

I'm not using any GIFS so should i just fork Glide and remove the AnimatedGifEncoder from the library or should i just ignore this?

  • If the author is in the US, their work is in the public domain, as I read it. You can ignore and keep using it. Or is the question something more I don't quite get? Commented Feb 24, 2020 at 9:19
  • @Prof.Falkencontractbreached I'm using the glide library from github in my app, github.com/bumptech/glide/blob/master/LICENSE I list all licenses in the about section of my app (required by apache license) but then i can't find anything about the Unisys LZW patent

    Patents are mostly orthogonal to licenses. The mention of the patent is just a "reader beware, there are also other issues you may want to consider, than the license and copyright status of this code". (In practice, this particular patent is expired: en.wikipedia.org/wiki/Lempel%E2%80%93Ziv%E2%80%93Welch#Patents ) Commented Feb 24, 2020 at 9:52
