Sampo IP LLC v. Hewlett-Packard

Sampo IP LLC, the plaintiff, is a non-practicing entity (NPE) or patent assertion entity (PAE). It is a wholly-owned subsidiary of Marathon Patent Group, Inc. (now known as MARA Holdings, Inc.), an intellectual property services and patent licensing company that acquires and monetizes patent portfolios. The defendant, Hewlett-Packard (HP), is a multinational information technology company known for its printers, personal computers, software, and IT services.

The lawsuit alleges infringement of US Patent 8,015,495, titled "Centrifugal Communication and Collaboration Method". This patent generally relates to systems and methods for facilitating communication and collaboration among members of a distributed discussion group using various communication devices and a central agent. The accused products or services from Hewlett-Packard are broadly described as communications systems and methods that allegedly infringe the claims of the asserted patent.

The case was filed in the United States District Court for the Eastern District of Texas in 2013, a venue historically favored by patent plaintiffs due to its patent-friendly reputation, predictable scheduling orders, and experienced judiciary in patent matters. While the specific judge for this particular case isn't readily available in the initial search results, the Eastern District of Texas is known for its efficiency in moving patent cases to trial.

This case is notable as part of a broader patent assertion campaign by Sampo IP LLC and its parent company, Marathon Patent Group. Sampo IP filed similar lawsuits against a number of other prominent companies, including Starbucks, E*Trade, Aetna, Avon, Yum! Brands, Alcatel-Lucent, Facebook, Intuit, Amazon, LinkedIn, and eBay, asserting the same patent family. This pattern is characteristic of NPEs leveraging patent portfolios against multiple defendants across various industries. While the general subject matter of the patent (communication and collaboration) is broad, the specific impact on the industry or any IPR linkage directly related to this specific case against Hewlett-Packard is not immediately clear from the provided search results. However, HP has been involved in other patent litigations, including IPRs, demonstrating its active defense against patent assertions.

This summary details the key legal developments and outcome of the patent infringement litigation involving Hewlett-Packard. It's important to note a discrepancy in the provided patent number: while the prompt refers to US patent 8015495, all significant litigation details for Hewlett-Packard concerning "Remote Power" and "Power over Ethernet" consistently point to U.S. Patent No. 6,218,930 (referred to as the "'930 patent" or "Remote Power Patent"). Furthermore, the plaintiff for this extensive litigation against Hewlett-Packard was Network-1 Technologies, Inc., not Sampo IP LLC. This summary will therefore focus on the case of Network-1 Technologies, Inc. v. Hewlett-Packard Company concerning U.S. Patent No. 6,218,930.

Key Legal Developments and Outcome:

1. Filing & Initial Pleadings (U.S. Patent No. 6,218,930):

• Lawsuit Filing: Network-1 Technologies, Inc. initiated a patent infringement lawsuit against Hewlett-Packard Company and Hewlett-Packard Enterprise Company (collectively, "HP") in 2011 in the U.S. District Court for the Eastern District of Texas. The case was assigned civil action number 6:13-cv-00072.

2. Pre-trial Motions of Substance:

• Stay Pending IPR: After Network-1 filed its complaint, co-defendant Avaya Inc. ("Avaya") petitioned for an Inter Partes Review (IPR) of the '930 patent in 2013. The district court subsequently stayed the litigation proceedings pending the IPR's outcome.
• HP's IPR Joinder: HP later filed its own IPR petition on different grounds, which was denied. HP then filed another IPR petition containing only the grounds already instituted in the Avaya IPR and moved to join the existing Avaya IPR. The Patent Trial and Appeal Board (PTAB) granted HP's motion to join.

3. Claim Construction (Markman) Outcomes:

• In 2017, the district court issued its construction of disputed claim terms, including "low level current" and "main power source."

4. Trial Events, Verdict, and Post-Trial Motions:

• Jury Trial: The case proceeded to a jury trial in November 2017 in the Eastern District of Texas.
• Jury Verdict: The jury returned a verdict finding that the asserted claims of the '930 patent were not infringed by HP and were invalid as obvious.
• Post-Trial Motions:
  • The district court denied Network-1's request for a new trial on infringement.
  • The district court granted Network-1's motion for Judgment as a Matter of Law (JMOL) on validity, thereby overturning the jury's verdict of invalidity. This decision was based on the court's finding that HP was estopped from raising certain invalidity arguments due to its joinder in the Avaya IPR.
  • In a separate bench trial in May 2018, the court also issued findings of fact and conclusions of law, determining that HP failed to meet its burden on its inequitable conduct defense.
• Final Judgment: The district court issued a Final Judgment and corresponding Order on August 29, 2018.

5. Appeal:

• Federal Circuit Appeal (2020): Network-1 appealed the district court's denial of a new trial on infringement, arguing erroneous claim construction. HP cross-appealed the district court's JMOL on validity (regarding IPR estoppel) and also challenged whether certain claims were improperly broadened during reexamination.
• Federal Circuit Decision (September 24, 2020; modified November 20, 2020): The U.S. Court of Appeals for the Federal Circuit issued a decision (modified on November 20, 2020) that:
  • Affirmed the district court's construction of "low level current" but found error in the construction of "main power source." As a result of this error, the Federal Circuit vacated the district court's judgment of non-infringement and remanded for a new trial on infringement with the correct claim construction.
  • Vacated the district court's JMOL of validity, concluding that HP was not statutorily estopped under 35 U.S.C. § 315(e) from raising invalidity challenges that it could not have reasonably raised through its joinder to the Avaya IPR. The court remanded for further proceedings on validity.
  • Affirmed the district court's judgment that the asserted claims were not improperly broadened during reexamination.

6. Settlement:

• Resolution: On July 27, 2021, Network-1 Technologies, Inc. announced that it had agreed to settle its patent litigation with Hewlett-Packard Company and Hewlett-Packard Enterprise Company.
• Terms: Hewlett-Packard Enterprise Company agreed to pay Network-1 $17,000,000 in full settlement of the litigation. In return, HP received a fully paid license and release to the '930 patent for its full term, which had expired on March 7, 2020. This license covered sales of Power over Ethernet (PoE) products by HP and its subsidiary Aruba Networks, Inc.

7. Parallel PTAB IPR/PGR Proceedings:

• Avaya IPR (IPR2013-00071): This IPR, initiated by co-defendant Avaya in 2013, resulted in the PTAB instituting review of claims 6 and 9 of the '930 patent on grounds of anticipation and obviousness.
• HP's Joinder: HP successfully joined the Avaya IPR. The PTAB ultimately held that neither claim 6 nor claim 9 was unpatentable over the instituted grounds, a decision later affirmed by the Federal Circuit.
• Reexaminations: The '930 patent also underwent two reexaminations (No. 90/012,401 and No. 90/013,444), concluding in October 2014 and November 2015, respectively, which confirmed the patentability of various claims.

Sampo IP LLC retained Mishcon de Reya New York LLP as litigation counsel in its patent infringement lawsuit against Hewlett-Packard Company. The case, filed in May 2013 in the United States District Court for the Eastern District of Texas, alleged infringement of U.S. Patent No. 8,015,495, among others.
