Case Overview
The Parties
⚖️ Plaintiff
Patent assertion entity (PAE) that holds a portfolio of wireless data transmission patents. The company’s business model centers on licensing and enforcement of its IP assets rather than commercial product development.
🛡️ Defendant
One of the United States’ largest brick-and-mortar and digital booksellers, with a significant digital ecosystem anchored by its Nook e-reader platform and mobile application. Nook Digital, LLC operates as the digital media subsidiary managing the Nook application platform across mobile devices.
Patents at Issue
This case involved four U.S. patents, all relating to wireless data communication and mobile device data management. These foundational-era wireless communication intellectual property patents (issued between 2005 and 2007) are frequently leveraged in modern patent assertion campaigns against mobile application developers.
- • US6983139B2 — wireless data delivery technology
- • US7058395B2 — mobile wireless communication methods
- • US7212811B2 — wireless data transmission systems
- • US7292844B2 — mobile electronic device data protocols

The Verdict & Legal Analysis
Outcome
The case concluded via voluntary dismissal with prejudice, entered by order of Chief Judge Mazzant upon consideration of Plaintiff Push Data LLC’s Notice of Voluntary Dismissal. The operative order states:
“All claims asserted in this suit against Defendants Barnes & Noble, Inc. and Nook Digital, LLC are hereby dismissed with prejudice, and without right of appeal, with each party to bear its own costs, expenses, and attorneys’ fees.”
No damages were awarded. No injunctive relief was granted. Each party absorbed its own litigation costs. The dismissal with prejudice means Push Data LLC is permanently barred from reasserting the same claims against these defendants on the same patents.
Key Legal Issues
The absence of any substantive rulings makes it impossible to assess judicial findings on claim construction, validity, or infringement merits. What is legally notable, however, is the “with prejudice” designation of the dismissal. A voluntary dismissal with prejudice under Federal Rule of Civil Procedure 41(a) carries the same res judicata effect as a final judgment on the merits. Push Data cannot re-file against Barnes & Noble or Nook Digital on these four patents for the same accused products. This represents a meaningful concession — whether strategic or compelled — by the plaintiff.
The cost-bearing provision — each side paying its own fees — suggests the parties did not reach a formal settlement with monetary exchange, or that any resolution was reached on terms keeping fee-shifting off the table. It also indicates Barnes & Noble did not pursue attorneys’ fees under Octane Fitness v. ICON Health & Fitness (2014), which permits fee awards in “exceptional” patent cases.

Four U.S. patents: US6983139B2, US7058395B2, US7212811B2, and US7292844B2 — all relating to wireless data transmission and mobile device communication technology.
Plaintiff Push Data LLC filed a voluntary Notice of Dismissal With Prejudice. The specific business or legal rationale was not disclosed in public filings. The dismissal permanently bars re-assertion of these claims against the named defendants.
It reinforces that pre-Alice wireless data patents face significant enforcement headwinds, and that early, experienced defense counsel can facilitate rapid, cost-effective resolution in Eastern District patent cases.
