Two separate and almost simultaneous requests to the US Patent and Trade Mark Office have been issued in the US against Blackboard's US Patent 6,988,138. The first, on 17/11/2006 was issued by the New York based Software Freedom Law Center (SFLC), acting in support of the makers of 3 Open Source VLE systems: Moodle, Sakai, and ATutor. The second, on 1/12/2006, was issued by the Canadian VLE company Desire2Learn, against whom Blackboard issued patent infringement proceedings earlier in the year. On the same day Desire2Learn also issued an application to the court [64 kB PDF] for a stay in the patent infringement proceedings pending re-examination of Patent 6,988,138 by the US Patent and Trademark Office. 5/12/2006. Within 3 days, Blackboard had filed a rapidly produced, and extremely forcefully written 16 page opposition to Desire2Learn's application to the court for a stay, plus 5 exhibits, one of which is described as "a highly confidential submission to the U.S. Department of Justice during the approval process for Blackboard's merger with WebCT, in which Blackboard sets forth in detail the competitive threat posed by
Desire2Learn", and is not in the public domain. The tone and content of Blackboard's 16 page opposition shows that both companies are playing for very high stakes. There is an extract below. 7/12/2006. Desire2Learn has filed its from Al Essa, picking up on three key features of Blackboard's opposition to the stay: "We have a company that has seized community property - your property and mine - and now in broad daylight is wielding our knife to cut its competitor's throat". 11/12/2006. From the Desire2Learn patent information page: "On Friday,
December 8, during a routine scheduling conference held at the
courthouse in Beaumont, Texas, U.S. District Judge Clark of the Eastern
District of Texas denied Desire2Learn's Motion to Stay Proceedings. We
had requested that the Court stay - or put the litigation "on hold" -
while the U.S. Patent & Trademark Office reexamined the Blackboard
patent. Judge Clark's actions do not affect the reexamination request
that we filed with the U.S. Patent & Trademark Office on December 1."
SFLC's ex partes re-examination request is short and to the
point, with the main VLE-based prior art cited being the Irish VLE Top
Class, which the then Aberdeen University staff member Jim Kerslake investigated during the 1990s, and whose signed declaration is included in the SFLC re-examination request. Jim has posted a useful summary page relating to VLEs at that time,
which is a model of clarity, and is an indication of how important the
careful documentation of prior art can potentially be. SFLC's other two
citings are publications: Information sharing: collaborating across the networks, by MIT's Phyllis Galt and Susan Jones; and Enhancing teaching using the Internet,
by Stephen Hartley, Jill Gerhardt-Powals, Richard Stockton, Colin
McCormack, Dee Medley, Blaine Price, Margaret Reek, and Marguerite
Summers.
Desire2Learn's inter partes re-examination request is much more complicated and includes a mass of papers (SFLC's re-examination request is at the same URL). The Desire2Learn request references: details of systems available at the time (including Ceilidh, jointly developed by at Nottingham University, and Ngee Ann Polytechnic in Singapore); evidence relating to "role-based access control"; the previously featured
EDUCOM/NLII Instructional Management Systems Specifications Document;
and at least one sworn declaration. On a personal note it also includes
documents relating to the 1996 Renaissance Project, an EU ACTS
Project in which several Sheffield organisations, including The
Sheffield College, where I then worked, had a role.
What happens next? If the court - and it is quite a big if - grants the postponment requested by
Desire2Learn (and see the extract below for part of Desire2Learn's rationale for the postponment) then attention will switch to the 2
re-examination requests, which could possibly result in Patent 6,988,138 being
deleted, or modified, or consolidated. The process will not be quick. Blackboard will already surely be
aware of most if not all of the material assembled by SFLC and
Desire2Learn, and you'd expect, from its apparently unfazed reaction to SFLC's re-examination request, that it will have detailed responses (which might well up the ante) to both re-examination requests, just as the company was quick to oppose Desire2Learn's application to the court for a stay.
Extract from Desire2Learn's application for a stay in
the patent infringement proceedings.
The patent on which the plaintiff, Blackboard,
Inc. (“Blackboard”) has asserted patent infringement is currently the
subject of both an ex parte [i.e. the Software Freedom Law Center's] and an inter partes [i.e.
Desire2Learn's] reexamination request filed with the United States
Patent and Trademark Office (“PTO”). The currently pending ex parte
request seeks to invalidate the patent-in-suit based on prior art that
was never submitted to or considered by the PTO during the six years
that the patent was in prosecution. Likewise, the inter partes
reexamination request, filed by Desire2Learn Inc. (“Desire2Learn”),
seeks to invalidate the patent-in-suit not only based on prior art that
was not submitted to or considered by the PTO during the prosecution of
the patent-in-suit, but also based on prior art that is not part of the
pending ex parte request.
Because the currently pending ex parte reexamination, as well
as Desire2Learn’s inter partes reexamination request, will likely
narrow the issues or eliminate the need for trial and because doing so
would conserve resources, Desire2Learn requests that this Court enter
an order staying these proceedings pending the completion of the ex parte and inter partes reexaminations. EchoStar Technologies Corp. v. TiVo, Inc., 2006 WL 2501494, at *5 (E.D. Tex. July 14, 2006) (granting motion to stay proceedings pending an ex parte and inter partes reexamination).
Extract from Blackboard's opposition to Desire2Learn's request for a stay in
the patent infringement proceedings.
Plaintiff Blackboard Inc. (“Blackboard”) filed this case in July. In the answer that
Defendant Desire2Learn Inc. (“Desire2Learn”) filed in September, Desire2Learn identified
alleged prior art that it asserts renders the patent-in-suit, U.S. Patent 6,988,138 B1 (the “’138
patent”), invalid. Now, in December, less than a week before the Case Management Conference,
and more than six weeks after the parties agreed in their Rule 26(f) Joint Conference Report to a
February 2008 trial date and a discovery schedule that has already required Blackboard to
expend significant resources, Desire2Learn has filed an inter partes reexamination with the
United States Patent and Trademark Office (the “PTO”) and simultaneously moved to stay this
case. Desire2Learn’s motion is a stall tactic crafted to allow it to continue its infringement of
Blackboard’s intellectual property for as long as possible. Staying the case would not create
judicial efficiency. To the contrary, a stay would harm Blackboard by allowing Desire2Learn to
avoid an injunction and continue to infringe Blackboard’s presumptively valid patent.
Note 1. On 2/12/2006 I gave this post a somewhat more cautious emphasis once a helpful reader had pointed out the lack of unequivocal data available on the successs rates of inter partes re-examination requests. On 3/12/2006 I added links below to two USPTO documents summarising data relating to the processing of patent re-examination requests. Reference is made to one of these documents in my response to Joseph Hardin's comment below. On 4/12/2006 I added a link to the archived Ceilidh site. On 5/12/2006 I added a note about Blackboard's opposition to the application for a stay, and an extract from that document.
Note 2. Links to USPTO documents summarising, to 30 June 2006, data concerning the processing of ex partes re-examination requests [100 kB PDF] and inter partes re-examination requests [100 kB PDF].
