Reissue & Reexam Live Blog: Litigation Strategies

Next up is Scott McKeown of Oblon Spivak, writer for Patents Post Grant and Practice Center Contributor.  He discussed patent reexamination as a litigation tool.  Some highlights from his presentation…

1. Reexamination v. Litigation Standards: A huge benefit of reexamination with concurrent litigation is in the lower standards. No presumption of validity, preponderance of evidence standard and broadest reasonable claim interpretation.
2. Patents that are ideal for reexamination (invalidity purposes): broad claims, patents subject to inter partes reexam, predictable arts (KSR), and patents with alternative basis for attack.
3. Patents that are less ideal (invalidity purposes only): famous products (TiVo, Plavix, iPhone), unpredictable arts (Chem, Bio/Pharma), large portfolios (Rambus), portfolios with active continuations.  However complete invalidity is only ONE of MANY litigation purposes. (more…)

Reissue & Reexam Live Blog: Petition Practice in Patent Reexam From USPTO Perspective

Next speaker is Mr. Kenneth Schor of the USPTO’s Office of Patent Legal Administration (OPLA).  He is discussing petition practice in patent reexamination from a USPTO perspective. He says that a petition should include:a statement of the type of relief requested and the authorizing provision of the rules, statute, etc.; a statement of the facts; an identification of the points that are to be reviewed; and the fee, where required, to avoid summary dismissal (it’s recommended that a petition include a general authorization to charge deposit account, in case relief can be granted only based on a regulation requiring a higher fee than submitted).

Live Blog: PLI’s Reissue & Reexamination Strategies & Tactics With Concurrent Litigation

PLI’s Reissue and Reexamination Strategies and Tactics with Concurrent Litigation kicked off this morning.  First up is Todd Baker of Oblon Spivak.  In his Reissue overview, Baker explains that common bases for filing a reissue application include: the original patent claims are too narrow or too broad, the disclosure contains inaccuracies, the applicant failed to assert or incorrectly asserted foreign priority, and/or the applicant failed to make reference to, or incorrectly made reference to, prior co-pending applications.  In his overview of Ex Parte Reexam, Baker explains ex parte reexams can be initiated by patent owner, third parties (may remain anonymous); or Director. He says requests must be based on prior art patents and printed publications; requests cannot be based on public use, sale priority of invention or derivation; and claims many not be broadened in any request.  He explains that reexamination of patent claims will result in targeted claims being cancelled; narrowed; or confirmed.  Baker went on to discuss pitfalls to avoid both in Reissue and Ex Parte Reexam.

Pitfalls to avoid in Reissue (oath):

1. The error must be specific.  Insufficient for oath to merely state: “this application is being filed to correct errors in the patent which may be noted from the changes made in the disclosure.”
2. Insufficient to merely reproduce the amended claims and assert that the error is evident from the amendment
3. Any error in the claims must be identified by reference to the specific claim(s) and the specific claim language wherein lies the error.
4. Preparing oath not a ministerial act
5. Adding a dependent claim to hedge against possible invalidity of original claims does not constitute an error correctible by reissue. Ex parte Tanaka
6. If the basis of the error is claiming more than the patentee was entitled to, then an original patent claim must be narrowed to satisfy s 251. (more…)

USPTO Warns Practitioners On Abusive Filings In Patent Reexamination

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

On January 10, 2011, I co-chaired PLI’s Reissue & Reexamination Strategies and Tactics with Concurrent Litigation 2011. Mr. Kenneth Schor, Senior Legal Adviser of the USPTO’s Office of Patent Legal Administration (OPLA) participated and presented a very informative lecture on proper petition practice in patent reexamination.

Mr. Schor made several points of great interest to all post grant practitioners namely:

1) It is improper to oppose many petitions in inter partes reexaminations or provide sur-replies to properly opposed petitions;

2) Improper petitions will be referred to the Office of Enrollment & Discipline (OED), and

3) Abusive petition practices are believed to be aggravating a growing petition inventory. (more…)

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.
