All 44 Blackboard Patent Claims Invalidated
- Tichy 19y agoWhat are the blackboard patents? It doesn't say in the slashdot post, nor in the article the slashdot post links to.
- rms 19y agoI can't seem to find an overview of all of them, but here are the ones Blackboard said they wouldn't enforce against pure open source software. http://www.blackboard.com/patent/FAQ_013107.htm http://www.blackboard.com/patent/FAQ_013107.htm I believe that their patents together meant that any commercial Blackboard-like software was infringing on their IP. This is a list of companies that were probably infringing on Blackboard's fortunately invalid patents. http://www.mfeldstein.com/the_blackboard_patent_claims_in_plain_english/ http://www.mfeldstein.com/the_blackboard_patent_claims_in_pl... http://www.google.com/patents?id=RX94AAAAEBAJ&dq=6,988,138 http://www.google.com/patents?id=RX94AAAAEBAJ&dq=6,988,1... That's their first and biggest one and it's obscene.
- mechanical_fish 19y agoI think we have reached the point in the patent wars where nobody cares what the actual patents are. Whenever I hear that a patent has been invalidated, I just reflexively smile. This is surely an irrational overreaction, but it's not as if the patent system hasn't been asking for it. If the patent bar wants me to bother reading the things they need to clean out the spam, the trolls, and the nonsense.
- JayNeely 19y agoDesire2Learn is the company that's been fighting to have Blackboard's patents invalidated, and they are maintaining a list of all legal documents pertaining to the case here: http://www.desire2learn.com/patent/files.html http://www.desire2learn.com/patent/files.html If you don't mind wading through scanned legal paperwork, I'm sure the patents in question are specified somewhere in there.
