There used to be a grace period of 1 year after public disclosure for filing. Don't know if it is still true, though I don't think the patent procedures have been changed in that area unless it is part of international normalization. The big deal is going to be with regard to the IETF rules. I don't know when they were updated to require mandatory licensing of anything disclosed or proposed for an IETF standard. -- Dennis -----Original Message----- From: w3c-dist-auth-request@w3.org [mailto:w3c-dist-auth-request@w3.org]On Behalf Of Jim Whitehead Sent: Wednesday, February 19, 2003 18:01 To: Chris Knight Cc: w3c-dist-auth@w3.org Subject: RE: Microsoft patent on typing Webdav properties Chris Knight writes: > I assume there is prior art to these? It's a shame that it got through > the patent review process. (Not a suprise, however.) IANAL. Many of the claims in the Microsoft patents are very specific to HTTP, specific methods, and use of XML. There is clear prior art for ACL (easy to find drafts in Google that predate the application). DASL is a bit tricky -- the first draft did go our before the application, but only by a week. Still, we can point to email messages that clearly indicate that people on the patent application were working on the DASL specification. I'm also not sure whether revealing the idea of SQL wrapped in XML over HTTP at the public, open DASL working meetings also constitutes disclosure of the invention. - Jim
