PTAB challenges

Proceedings Overview

There have been zero AIA trial proceedings filed at the PTAB against US patent 6,266,674. This gives a defendant a unique defensive posture: while the patent has not been tested at the PTAB, it was comprehensively invalidated in district court litigation, rendering its claims unenforceable.

No PTAB Proceedings on File

A thorough search of USPTO records and public litigation data confirms that no Inter Partes Review (IPR), Post-Grant Review (PGR), or Covered Business Method (CBM) proceedings have ever been initiated against US Patent 6,266,674.

Strategic Summary

The absence of PTAB activity for a patent so widely litigated is a significant strategic signal. The defensive efforts against the eDekka assertion campaign were consolidated and focused on a dispositive motion in district court, which proved successful and obviated the need for parallel PTAB challenges.

• CANCELED vs. SUSTAINED vs. UNTESTED Claims: All 52 claims of the '674 patent are UNTESTED at the PTAB. However, they are all INVALID and UNENFORCEABLE as a result of the district court litigation. On September 21, 2015, Judge Rodney Gilstrap of the U.S. District Court for the Eastern District of Texas granted summary judgment that the patent was invalid under 35 U.S.C. § 101 for claiming an abstract idea without an inventive concept. This ruling, in the lead case eDekka LLC v. 3Balls.com Inc., effectively terminated all 168 consolidated lawsuits filed by eDekka.

• Estoppel Landscape: Because no IPRs were ever instituted and carried to a Final Written Decision, there is no petitioner estoppel under 35 U.S.C. § 315(e)(2). A defendant today would be free to raise any prior-art-based invalidity grounds in a potential IPR, as no grounds were ever raised or could have been reasonably raised in a prior proceeding.

• Pattern Signals: The clear pattern was that the large group of defendants, facing a prolific litigation campaign from an NPE, coordinated their defense. They strategically chose to pursue a § 101 patent eligibility challenge in district court. This was a common strategy for challenging broad business method or software patents, particularly in the years following the Supreme Court's decision in Alice Corp. v. CLS Bank Int'l. Judge Gilstrap's decision to grant the motion was noteworthy at the time and was a decisive end to the litigation. Following the invalidity ruling, he also deemed the case "exceptional" and awarded attorneys' fees against eDekka, finding its litigation conduct "objectively unreasonable".

Recommended Next Steps

For a defendant facing an assertion of US patent 6,266,674 today, the strategic focus should be entirely on the prior district court invalidation, not on filing a new PTAB proceeding.

• Absence of PTAB Activity is Key: State plainly that there are no PTAB proceedings, past or present, concerning this patent. The patent's invalidity was established in federal court.

• Cite the Controlling Court Decision: The dispositive document is the Memorandum Opinion and Order from September 21, 2015, in eDekka LLC v. 3balls.com, Inc., No. 2:15-cv-00541 (E.D. Tex.). In his ruling, Judge Gilstrap found the patent was directed to the abstract idea of "storing and labeling information" without adding a sufficient inventive concept to transform it into a patent-eligible invention. The court concluded:

  "The Court finds that no inventive concept exists to transform the claimed abstract idea into a patent-eligible concept." (eDekka LLC v. 3Balls.com Inc., 2015 WL 5579840, at *5).

Any attempt to re-assert this patent would face a significant and likely insurmountable hurdle due to this prior, final judgment of invalidity. A defendant should immediately bring this ruling to the attention of any asserting party and, if necessary, the court, potentially seeking sanctions for frivolous litigation.
