Hoi,<br>In essence there are the SignWriting fonts created by Valerie. They can be copyrighted and are copyrighted. All the later iterations are in essence a derivation. It is for this reason that it is so important that these characters / glyphs are licensed in such a way that everyone is empowered to create new iterations of these glyphs.
<br><br>When a license is chosen that does not allow for the freedom to improve them, create new fonts, it is not unlikely that a court will allow for it any way because the basic character set is essential for the writing of sign languages. With a license that has as its intent to allow for the freedom to improve on the basic idea, it will be possible to define limits to this freedom when it is thought to be a good idea.
<br><br>A program that combines the basic shapes in SignWriting needs a license for the program. The characters it produces are in essence derivations of the original SignWriting characters. The way you break these characters down in its essential parts in order to build one character at a time represents an algorithm. This algorithm could be patented if it is thought to be non-obvious. Applying for such a patent seems ludicrous to me because it is rather obvious. It is done to some extend in Unicode and this is what is called "prior art".
<br><br>You can design different basic shapes that fit together and that can be manipulated by your program. One such a set could be called a font. Depending on the copyright and the license of the upstream material, you are able to select a license.
<br><br>It seems obvious to me that with SignWriting seeking more people to write their sign language, it is relevant to allow people use the SignWriting characters and fonts, the software and material as freely as possible. In this way you grow an ecosystem that will be of benefit to the whole community. It seems to me that SignWriting is the best defence that sign languages have. It gains strength in the number of people able to write and promote their sign language.
