Thread: Danish database patent
Hi I hope this is the right list to write to. A danish company just got a patent which we at SSLUG www.sslug.dk do not think is a new invention. I want to get in contact with somebody who can confirm that this patent is not new and has been in PostgreSQL before the patent was taken. If we can prove that this patent was not new when requested, we plan to start a trial against the company or Patent Office to get the patent redrawn. It is a bit troublesome to get all the documents. You can find a tar-ball here: http://www.sslug.dk/~chlor/targit.tgz There is four pages which is interesting: http://www.sslug.dk/~chlor/targit/bns01.pdf http://www.sslug.dk/~chlor/targit/bns31.pdfhttp://www.sslug.dk/~chlor/targit/bns32.pdf http://www.sslug.dk/~chlor/targit/bns33.pdf best regards Patent group, SSLUG, Hans Schou

So there is not much hope that postgres has done it before, as 99% of postgres is concerned with backend activities. ----------- Hannu

Yes, it's a query generation technique separate from the database server, generating and executing SQL queries on a set of tables in order to satisfy some goal. Has nothing to do with the RDBMS itself. - Don Baccus, Portland OR <dhogaza@pacifier.com> Nature photos, on-line guides, Pacific Northwest Rare Bird Alert Serviceand other goodies at http://donb.photo.net.
