Have Your Cake and Indemnify It, Too

In many cases brought before the Board, the Petitioner is defending against a real-party-in-interest challenge. In Acxiom v. Phoenix Licensing, LLC, CBM2015-00134 et seq., which involved a covered business method review, the Petitioner was attempting to show that it was a real party in interest, and it failed.

In Acxiom, the Petitioner claimed that it was a real-party-in-interest or privy to third parties that had been sued for infringement of the subject patents.… More

What’s In a Claim? IPR Can Be Denied For Indefiniteness

ptab-blogPetitioners challenging patents with known indefiniteness issues must carefully consider their options when filing an IPR, which may address only a claim’s patentability in view of the prior art under 35 U.S.C. § 102 or 103 — not under 35 U.S.C. § 112.  The PTAB also requires an IPR petition to explain “[h]ow the challenged claim is to be construed.”  37 C.F.R. § 42.104(b)(3).  Thus for claim terms to be construed under §112 ¶6,… More

Happy Thanksgiving From the PTABloggers


We at Foley Hoag wish you a very happy Thanksgiving.  And while you are gorging on turkey, cranberries and football, we remind you that patents still lurk on Thanksgiving Day!  As a public service, you may wish to use (license?) this apparatus (U.S. Patent No. 9,016,190) to avoid any frying turkey explosions.

The PTAB’s Subpoena Power

Parties harness the PTAB’s authority to compel third parties only in rare situations.

The PTAB’s tight trial schedule allows no room for protracted discovery fights.  That usually doesn’t matter, because parties rarely seek more than routine cross-examination of the opponent’s witnesses.  And even when they seek other evidence, such as when investigating a real-party-in-interest issue, the evidence sought usually is in the control of a party to the proceeding.… More

Motion for Observations: A Late Game-Changer

Antique hourglass, black sand, textured background. Right of image, blank space on left, landscape, top half almost empty.

Often overlooked due to its late timing and limited scope, the Motion for Observations provides a mechanism for introducing dispositive evidence when there’s little further the opponent can do about it.

The motion is limited to addressing cross-examination testimony of the opponent’s reply witnesses.  There are normally at most two substantive Replies in a proceeding: the Petitioner’s Reply in support of the Petition,… More

The Cost-Effectiveness of PTAB Proceedings

image001PTAB litigation is less expensive and faster than the old ways.

An old joke about patent litigation among trial counsel that produces cringes when told to clients is that patent litigation is known as the “sport of kings.” That is because of the great expense of investigating, pleading, discovery, motion practice, expert discovery, pretrial preparation, and trial in a traditional patent case. Like that other sport of kings,… More

Is the PTAB Blindly Throwing Darts?

iStock_000000511731_SmallThere’s been an issue bubbling under the surface of PTAB AIA proceedings: redundant grounds.

The issue boiled to prominence last week during oral argument at the Federal Circuit in Shaw Industries Group v. Automated Creel Systems, No. 2015-1116, which was an appeal of IPR2013-00132. Shaw, the Petitioner, had several of its grounds directed to certain claims denied in the interests of “efficiency” and then lost on the instituted grounds for those claims in the final decision.… More

315(b) Bars Lurk in Unlikely Places

iStock_000004696356_Small315(b) bars are rare, but when applicable they kill petitions dead.  Many 315(b) denials involve a straightforward application of the statute, i.e., the Petitioner had been served with a complaint alleging infringement of the challenged patent more than one year before the petition date.  E.g. Accord Healthcare Inc. v. Eli Lily & Co.IPR2013-00356, Paper 13 (Kamholz, APJ).  But I also wrote decisions denying petitions because 315(b) had been triggered in a more nuanced or unexpected way.  … More

Ripeness and Mootness at the PTAB

convenant not to sueUnlike other types of post-grant challenges, in order to invoke a covered business method challenge, a petitioner must establish that it has been sued or threatened with a charge of infringement. A petitioner will have standing to file a petition for covered business method review if it has been sued already or if it “has been charged with infringement.” So exactly what does the phrase, “has been charged with infringement” mean?… More

How Many Litigated Patents are Actually Subject to PTAB Proceedings?

The current wisdom is that if you are planning to enforce a patent, you should budget to defend the inevitable IPR or CBM.  However, a review of the first three years of AIA proceedings suggests that the chance of a litigated patent being challenged in the PTAB is only around 20%.  This analysis is from the perspective of individual patents, rather than the number of cases impacted, and so does not directly address multiple assertions of the same patent.… More

The Patent Owner Calls the Shots in Trial

The Patent Owner calls the shotsPetitioners often view the Petition as an opening salvo in what they expect will be a back-and-forth process.  In reality, the Petitioner loses control of the proceeding after the Petition is filed.  Once trial is instituted, the Patent Owner calls the shots.  For example:

  • The Patent Owner decides what new witness testimony to introduce and thereby limits the scope of the Petitioner’s discovery.
  • The Patent Owner decides what issues to raise in the Response and thereby limits the scope of the Petitioner’s Reply.…
