I suppose it could be possible to patent something and let the patent expire so that it is registered at the patent office but not enforcable. No one else could patent it then. I get curious about the RLE patent. I heard Someone has a patent on run length encoding and I wonder how long they have had it because I remember RLE code running on a sinclair spectrum in the 80's before the whole patenting thing, so there is very clear prior art on this but someone claims to have a patent on this!? Does anyone know about this. love Freya __________________________________________________ Do You Yahoo!? Yahoo! Shopping - Thousands of Stores.

So even if it was patented back then it would have long expired by now. There is plenty of demonstrable RLE prior art so I would ignore any RLE patents. -Dan --- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http://www.xiph.org/ogg/ To unsubscribe from this list, send a message to 'vorbis-request@xiph.org' containing only the word 'unsubscribe' in the body.
