Patents are as much designed to confuse and dissuade someone from using something as they are to patent something. Reading a patent is often harder than killing the nearest chicken, strewing it's entrails allover the yard, and then trying to make some sense of it.

Is there any way of finding out instead of asking him directly? Maybe the patent places have online info? I did a quick search at USPTO at http://patft.uspto.gov/netahtml/search-bool.html on UB and Tree and index and database and found among other things a US patent no. 5,826,253 on mechanism very similar to LISTEN/NOTIFY, afforded to Borland on October 20, 1998 based on application from April 19, 1996. We should be safe as already Postgres95 had them ;) when I searched for UB and Tree and index and database and Bayer 0 results came back. when I omitted UB and searched for Tree and index and database and Bayer I got 27 results, first of them on Method and composition for improving sexual fitness ;) the one possibly related related to our Bayer was nr 6,219,662 on Supporting database indexes based on a generalized B-tree index which had reference to : Rudolf Bayer, The Universal B-Tree for Multidimensional Indexing: General Concepts, Worldwide Computing and Its Applications, International Conference, WWCA '97, Tsukuba, Japan, (Mar. 1997), pp. 198-209. and German patent 0 650 131 A1 which may be also relevant -- Hannu ---(end of broadcast)--- TIP 5: Have you checked our extensive FAQ? http://www.postgresql.org/users-lounge/docs/faq.html

Hi everyone, This is Prof. Bayer's response to the question is it alright to use UB-Tree's in Open Source projects?. It's a No, but we can discuss a licensing model type answer. Regards and best wishes, Justin Clift Original Message Subject: AW: More UB-Tree patent information Date: Wed, 10 Apr 2002 15:26:05 +0200 From: Prof. Rudolf Bayer [EMAIL PROTECTED] To: Justin Clift [EMAIL PROTECTED] Dear Justin, I am personally holder of the patents. concerning your question: Specifically wondering if it's alright to use UB-Tree's in Open Source projects. the answer is NO, unless there is a patent agreement with me. Please let me know, what specifically the interests and business models are, then we could discuss a licensing model in line with the already existing license agreements, best regards, R.

April 2002 23:04 An: Professor Rudolf Bayer Cc: PostgreSQL General Mailing List Betreff: More UB-Tree patent information Hi Prof. Bayer, Haven't heard anything back from you regarding the patents on UB-Tree's. Specifically wondering if it's alright to use UB-Tree's in Open Source projects. On a related topic, in your paper The Universal B-Tree for multidimensional Indexing (http://mistral.in.tum.de/results/publications/TUM-I9637.pdf) you mention a German Patent Pending number of 196 35 429.3, is this the one which was approved in Europe? In the paper Bulk Loading a Data Warehouse built upon a UB-Tree (http://mistral.in.tum.de/results/publications/FKM+00.pdf) it mentions the Japanese Patent filed on 22nd May 2000, Application Number 2000-149648. Is this the Japanese patent for UB-Trees which hasn't yet been approved? :) Regards and best wishes, Justin Clift -- My grandfather once told me that there are two kinds of people: those who work and those who take the credit.
