There are two recent patent lawsuits in the data warehouse DBMS market. In one, Sybase is suing Vertica. In another, an individual named Cary Jardin (techie founder of XPrime, a sort of predecessor company to ParAccel) is suing DATAllegro. Naturally, there's press coverage of the DATAllegro case, due in part to its surely non-coincidental timing right after the Microsoft acquisition was announced and in part to a vigorous PR campaign around it. And the Sybase case so excited one troll that he posted identical references to it on about 12 different threads in this blog, as well as to a variety of Vertica-related articles in the online trade press. But I think it's very unlikely that either of these cases turns out to much matter.I've been a software industry analyst since 1981, covering DBMS throughout that period. Perhaps I'm getting senile, but I can recall only one software patent case in those 27 years that wound up having any material effect on enterprise software users - Marcam/Ross Systems, about process manufacturing ERP software. Business Objects/Cognos doesn't count; Business Objects enjoyed the cash, but Cognos easily afforded the payments. The Lotus/Borland case about Quattro Pro's compatibility with 1-2-3 doesn't count either; the issue there wasn't patents.
So I haven't studied the patents and cases in question seriously myself, since I think it's very unlikely the trouble to do so will prove worthwhile. That said, DATAllegro CEO Stuart Frost told me that Cory Jardin's patent was something he thought was invalid before it ever was submitted, because of prior art, and that the application was formally submitted without reference to prior art. (Bad idea if you want the patent to hold up to reexamination when you try to enforce it later.) Frost claims that DATAllegro doesn't come close to infringing anyway, and he also rejects the allegation that his own patents or applications in the area are for similar claims to those Jardin asserts.
As for the Sybase case - I don't know which specific patents are alleged to be infringed. That said, US Patents 5794229 and 5918225 (issued in 1998 and 1999, respectively), both read in their first claim as if they pretty much patent the idea of columnar SQL DBMS with compressed data, especially dictionary/token compression. The "SQL" part is important, because otherwise they'd be blown out immediately by all sorts of prior art, e.g. from Essbase and Verity, or even Excel. Still, given the prevalence of ODBC access even in the 1990s, I'm hard-pressed to imagine how those patents could have any significant validity.
Also, the Sybase case was filed in Texas, which seems to be an oddly irrelevant venue. I wonder what their motive, or even excuse, for that choice was.
