Greetings, I would like to contribute my $.02 to this issue. I speak as not a lawyer but as someone tho worked one and a half year in a patent bureau and even got a certificate from WIPO (http://academy.wipo.int/ those who interested may attend the course too, it is free). First, the whole point of USPTO's publishing patents which are pending is to get it publicly reviewed and collect objections before final decision. So, those of you who live in US file and objection based on "USENIX File & Storage Technologies Conference (FAST), March 31, 2003, San Francisco, CA" mentioned by Jan Wieck. Filing and objection should be not be too expensive though you may need help of professional lawyer form a patent bureau co compose a solid objection. I will call my old friends from Patent Bureau tomorrow to get a professional advise on this matter. Second, a pending patent is not a granted patent, one is not infringing anything by distributing technology based in a pending patent. As soon as patent is granted AND "Cease and Desist" letter form IBM is received removing offending code, removing offending versions from download and and notifying customers to upgrade to a new version is sufficient. I am not sure about CVS, apparently it need to be cleared out too. A vaguely similar issue happened between Pixar, the developer of Renderman and Exluna the developer of BMRT, a free (but not open source) raytracing 3D renderer. Pixar sued Exluna for willful patent infringement. Exluna released a new version of BMRT - 2.6 without offending technology and ensured that version 2.5 is removed from all mirrors. For quite a lot of time -and even now- one of the most valuable things a 3D designer may own is a copy of BMRT version 2.5. Exluna was intended to defend themselves in court but soon ran out of money, settled with Pixar and was swallowed by nVidia. A sad story indeed. A story of how a big company squashes a small one using patents. Read more at: http://www.renderman.org/RMR/OtherLinks/blackSIGGRAPH.html The point here is that IBM may force PostgreSQL Global Development Group to remove offending version if patent is granted. But, lastly, as it was pointed out before it would be a very bad publicity for IBM and, in my opinion, very good publicity for PostgreSQL. IBM will admit that PostgreSQL is a worthy competitor. Thus, in my personal opinion IBM will never threat PostgreSQL. We can remove offending code but host patches to introduce the code in a country that does accept software patents. It would be even better for publicity. IBM can NEVER sue customers for using infringing code before first informing them of infringement and giving reasonable time to upgrade to uninfringing version. So, in short my advise is: 1. File an objection with USPTO. And maybe an informative letter to IBM legal department mentioning USENIX paper. 2. Ifpatent is granted, contact IBM and request an unlimited, perpetual license to use the technology 3. If IBM refuses, removethe offending code, clean up CVS and shout from the rooftops about the hypocrisy of IBM. Hope it helps make up your mind, Best regards, Nicolai Tufar P.S. But if filing date really is 2002 and there is no prior art me may skip step 1.
