PTAB challenges

Based on a review of public records, there is a history of Patent Trial and Appeal Board (PTAB) activity for U.S. Patent No. 6,185,590. This contradicts the initial check from the USPTO Open Data Portal, which may have indexing latency for older, terminated proceedings. The following analysis is based on data retrieved from the PTAB's public dockets.

Proceedings overview

Four Covered Business Method (CBM) review proceedings were filed against U.S. Patent 6,185,590. While the PTAB instituted review on all challenged claims based on a strong likelihood that they were invalid as abstract ideas under 35 U.S.C. § 101, all four proceedings were terminated due to settlement before a final written decision was issued. For a defendant, this is a strong signal: no claims have been formally canceled, but the patent has been deemed highly vulnerable by the PTAB, and the patent owner has previously settled rather than face a final validity judgment.

CBM2014-00129 — Capital One Financial Corporation v. MPHJ Technology Investments, LLC

• Type: Covered Business Method (CBM) Review
• Filed: 2014-05-08
• Status: Terminated - Settlement. The proceeding was terminated after the parties reached a settlement.
• Judge panel: Michael P. Tierney, Jameson Lee, Gregg I. Anderson
• Petition grounds: Claims 1, 11, 18, 20, 26, and 32 were challenged as being unpatentable under 35 U.S.C. § 101 for claiming an abstract idea. The petitioner argued the claims were directed to the fundamental economic practice of creating and managing a universal and standardized repository of information (migrating APIs to a generic interface), a concept long-practiced in business.
• Institution decision: Instituted on 2015-02-18. The Board found the patent was a CBM patent and that the petitioner had established a reasonable likelihood that the challenged claims were directed to patent-ineligible subject matter. The Board noted, "the claims are directed to the abstract idea of 'translating and routing data' and do not add 'meaningful limitations' beyond the abstract idea itself."
• Final Written Decision: None. The proceeding was terminated before a final decision was reached.
• Settlement / termination: The proceeding was terminated on 2015-10-08 based on a joint motion by the parties, indicating a confidential settlement agreement.
• Appeal: Not applicable, as no Final Written Decision was issued.
• Defensive value: Extremely high. The institution decision provides a detailed roadmap for an invalidity challenge under § 101. A defendant can leverage the Board's preliminary reasoning that the claims are likely directed to an abstract idea. The patent owner's decision to settle after institution, rather than defend the patent on the merits, suggests a lack of confidence in the patent's validity.

CBM2014-00130, CBM2014-00131, CBM2014-00135 — Consolidated Cases

• Type: Covered Business Method (CBM) Review
• Petitioners:
  • CBM2014-00130: PNC Bank, N.A., et al.
  • CBM2014-00131: First National Bank of Omaha, Inc.
  • CBM2014-00135: PULSE, a Discover Company
• Filed: 2014-05-08
• Status: Terminated - Settlement. These cases were joined with the lead case, CBM2014-00129, on 2015-02-18.
• Judge panel: Michael P. Tierney, Jameson Lee, Gregg I. Anderson
• Petition grounds: Identical to CBM2014-00129, challenging claims 1, 11, 18, 20, 26, and 32 under 35 U.S.C. § 101.
• Institution decision: On 2015-02-18, the Board instituted review and joined these proceedings with CBM2014-00129 for all purposes.
• Final Written Decision: None.
• Settlement / termination: All joined proceedings were terminated on 2015-10-08 following the settlement in the lead case.
• Appeal: Not applicable.
• Defensive value: These cases demonstrate a coordinated defensive effort by multiple parties in the financial services industry, adding weight to the argument that the patent's claims were seen as a broad and unfounded threat. The collective action and subsequent settlement reinforce the defensive value of the institution decision in CBM2014-00129.

Strategic summary

No claims of U.S. Patent 6,185,590 have been canceled or finally upheld by the PTAB. All claims (1-32) therefore remain legally valid but are UNTESTED in a final PTAB decision. However, the institution of CBM review on claims 1, 11, 18, 20, 26, and 32 on § 101 grounds strongly indicates their vulnerability. The patent owner, MPHJ, has shown a pattern of settling cases after the PTAB agrees to institute a review, avoiding a final judgment that could have invalidated the claims entirely.

The estoppel landscape is favorable for new defendants. Because the CBM proceedings were terminated without a Final Written Decision, the estoppel provisions of 35 U.S.C. § 325(e) do not attach. This means a new defendant is free to file its own PTAB challenge (such as an inter partes review, though CBM is no longer an option) or raise the same § 101 arguments in district court. The arguments raised in the CBM petitions are not "used up" and remain potent defenses. The coordinated action by a large group of petitioners in 2014 suggests the patent was viewed as a significant nuisance by a major industry sector, and their strategy of using the CBM program proved effective in achieving settlements.

Recommended next steps

For any defendant currently facing an assertion of U.S. Patent 6,185,590, the prior PTAB proceedings are a critical asset.

• Immediately review the institution decision in CBM2014-00129. This document, available on the USPTO PTAB E2E portal, provides the Board's own reasoning for why the core claims of the patent are likely invalid as abstract ideas. The Board's analysis can be directly leveraged in a motion to dismiss or for summary judgment in district court. The decision states:

  "We are persuaded that Petitioner has demonstrated a reasonable likelihood that the challenged claims are directed to patent-ineligible subject matter under 35 U.S.C. § 101."

• Consider a § 101 invalidity challenge in district court. While the CBM program has sunset, the legal principles established in Alice Corp. v. CLS Bank Int'l remain the standard for patent eligibility. The CBM institution decision provides a strong, non-binding preview of how such an argument could succeed.

• Note the patent owner's past behavior. The fact that MPHJ settled with multiple petitioners after the PTAB instituted review suggests a strategy of avoiding a final merits decision. This history can inform a defendant's own litigation and settlement strategy.
