Evidence of General Association Insufficient to Justify Real Party in Interest Discovery

Nov 16, 2015

Reading Time : 1 min

The statutory standard to seek discovery in the PTAB is “necessary in the interest of justice.” 35 U.S.C. § 316(a)(5).  The PTAB has previously held that a number of factors are important in determining whether discovery requests are “in the interest of justice,” including the likelihood of discovering something useful: 

  1. More Than A Possibility And Mere Allegation -- The mere possibility of finding something useful, and mere allegation that something useful will be found, are insufficient to demonstrate that the requested discovery is necessary in the interest of justice. The party requesting discovery should already be in possession of evidence tending to show beyond speculation that in fact something useful will be uncovered.
  2. Garmin Int’l, Inc. v. Cuozzo Speed Techs. LLC, IPR2012-00001, Paper 26 (PTAB Mar. 5, 2013) (discussing factors). 

Here, the PTAB denied Patent Owner’s request because it amounted to no more than a mere allegation of some kind of general association between Petitioner and RPX. “The alleged facts presented by Patent Owner during the conference call do not show more than a mere possibility that something useful will be discovered and are therefore insufficient to show beyond mere speculation that discovery would be in the interests of justice.”

Mangrove Partners Master Fund, Ltd. v. Virnetx Inc., IPR2015-01046, Paper 18 (PTAB Nov. 12, 2015)

The Federal Circuit recently affirmed a Patent Trial and Appeal Board decision finding claims that had been subject to an ex parte reexamination unpatentable. As a threshold issue, the court held that IPR estoppel under 35 USC § 315(e)(1) does not apply to ongoing ex parte reexaminations. Accordingly, the Patent Office did not err in continuing the reexamination after issuing final written decisions in co-pending IPRs.

The Federal Circuit recently denied a petition for a writ of mandamus that challenged the PTO Director’s reliance on “settled expectations” to discretionarily deny two inter partes review (IPR) petitions. In so doing, the court explained that, while it was not deciding whether the Director’s use of “settled expectations” was correct, the petitioner’s arguments about what factors the Director may consider when deciding whether to institute an IPR or post-grant review (PGR) are not generally reviewable and did not provide sufficient basis for mandamus review here.
