Inter Partes Reexamination Mechanics And Results

Our friends at Birch, Stewart, Kolasch and Birch sent in this article discussing inter partes reexamination, a fairly new proceeding in the PTO.  This post is a comprehensive guide to practice before the PTO in inter partes reexamination.  The article covers topics such as what patents qualify for inter  partes reexamination, who can request the proceeding and how to demonstrate a substantial new questions of patentability.  Here is an excerpt and link to the full article.

 The Creation of the Inter Partes Reexamination Procedure and Goals Thereof   

Reexamination is a procedure established by statute which permits the USPTO to reconsider the patentability of the claims in the issued patent in view of prior art which was not considered in the original prosecution of the application. [1 ]The reexamination statute was amended on November 29, 1999 by Public Law 106-113.  Public Law 106-113 authorized the extension of reexamination proceedings via an optional inter partesreexaminaiton procedure in addition to the existing ex parte reexamination procedure.  The final rules to implement the statutory inter partes reexamination option was published in the Federal Register on December 7, 2000 [2] and in the Official Gazette on January 2, 2001.

Supplemental Examinations to Consider, Reconsider, or Correct Patent-Related Information

The following article was sent in by Lisa A. Dolak , an Angela S. Cooney Professor of Law, Syracuse University College of Law and Practice Center Contributor.

A recent legislative proposal would authorize the U.S. Patent and Trademark Office (USPTO) to undertake a “supplemental examination” of an issued patent to “consider, reconsider, or correct information believed to be relevant to the patent.”  It would further bar the federal courts from holding a patent unenforceable “on the basis of conduct relating to information” considered during supplemental examination.

The obvious intent of the proposal is to constrain the federal courts’ power to entertain inequitable conduct-based challenges.  Its emergence is unsurprising, given the mounting dissatisfaction with the courts’ application of the inequitable conduct doctrine. However, because the bill proposes to provide patent owners a forum for effectively purging the taint associated with undisclosed or misrepresented information, it raises a number of questions, including questions relating to potential disciplinary consequences for practitioners.

US Supreme Court Accepts Microsoft Appeal in i4i Case

The following was sent in by Gene Quinn, of IPWatchdog and Practice Center Contributor.

Yesterday, the United States Supreme Court granted certiorari in Microsoft Corporation v. i4i Limited Partnership, with Chief Justice John Roberts taking no part in the decision or petition. The Supreme Court did not request the views of the Solicitor General, choosing rather to accept the matter with no input from the United States government.  The decision to grant cert. comes only days after the United States Patent and Trademark Office refused to grant reexamination of the patent in question.

Microsoft had filed an ex parte reexamination request on the patent in question, US Patent No. 5,787,449. The ‘449 patent exited reexamination unchanged. Microsoft then filed a second ex parte reexamination request, and it is this second request that was denied by the Patent Office on Wednesday, November 24, 2010. The denial of this second request means that the Patent Office did not believe there to be a substantial new question of patentability. (more…)

Chilling Effect of the USPTO Patent Reexamination Pilot Program?

The following post comes from Scott A. McKeown, partner at Oblon Spivak, Practice Center Contributor and writer for Patents Post Grant.

Participation in USPTO pilot program held against Patentee

In August of this year, the USPTO introduced a pilot program aimed at reducing the pendency of ex parte patent reexamination. The program entitled “Pilot Program for Waiver of Patent Owner’s Statement in Ex Parte reexamination Proceedings” is triggered once a new ex parte reexamination request is accorded an initial filing date. Once a Patentee agrees to waive the patent owner response period (since such statements are rarely filed), the USPTO is able to issue an office action together with the grant of an ex parte reexamination (just like inter partes reexamination).

Not surprisingly, many Patentess opt to maintain their right to file an Owner Statement in ex parte patent reexamination. (more…)

Rubbing The Court The Wrong Way In Seeking A Stay Pending Patent Reexamination

Reexamination can be an extremely useful alternative case management strategy.  More and more, litigants are using Reexamination to derail a litigation or limit damage exposure. Potential benefits of patent reexamination for defendants include providing an opportunity to stay concurrent litigation, creating an intervening defense, and providing additional prosecution history for a later claim construction ruling.  For Patentees, patent reexamination may provide a mechanism to add new claims to hedge against invalidity, avoid time consuming reissue proceedings, and target specific claims for reexamination/amendment while insulating others. Oblon Spivak Partner and Practice Center Contributor Scott A. McKeown, sent along this article he wrote with colleague Stephen G. Kunin for Patents Post Grant Blog.  The article discusses the litigation between 3M Innovative Properties Co., et al. and Envisionware, Inc., wherein Envisionware was seeking a stay pending patent reexamination.

On August 20, 2010, a motion to stay the litigation between 3M Innovative Properties Co., et al. and Envisionware, Inc. (0-09-cv-01594) (NDM) pending the outcome of a parallel patent reexamination was denied. At issue in the litigation are three of 3M’s patents relating to RFID technology, namely 6,232,870, 6,486,780 and 6,857,568. Envisionware requested inter partes reexamination of the ‘780 and ‘568 Patents. Curiously, since the third patent, the ‘870 Patent does not qualify for inter partes reexamination, reexamination of this patent was not sought at all. A non-final office action rejecting  the ’568 Patent claims was issued by the USPTO, the ‘780 Reexamination has yet to begin. On August 2, 2010, Envisionware filed the motion to stay the litigation.
