Compression algorithms are patented and are interesting. Of course you can't use them directly but certainly you can learn something from them.
Einstein worked in a patent bureau for years before he started inventing his own stuff. This is not a coincidence.
- brlewis 18y agoCan you relate a time when you went to the patent db to learn something about compression? And can you seriously postulate that good compression algorithms would be unknown without software patents?
- mojuba 18y agoI learned about them somewhere else, not in the DB, but that doesn't matter. They are published because they should, no matter where and how. PKZip was closed all those years when their patent was in the pending state. And no, I can't postulate that, because publishing vs. keeping secret would be left on companies' good will.
- brlewis 18y agoAccording to wikipedia, since 1993 pkzip has used an algorithm thought to be free of patents.
- mojuba 18y agoWikipedia says nothing about Katz's patents, but I well remember PKZip displaying a message "patent(s) pending".
- brlewis 18y agohttp://en.wikipedia.org/wiki/PKZIP#Version_history http://en.wikipedia.org/wiki/PKZIP#Version_history Click "deflating". It says the algorithm was used in gzip and PNG. Not exactly a poster child for innovation withering for lack of patents.
