Case Overview
A patent infringement dispute over a USB wall charger resolved swiftly — and quietly — when VoltStar Technologies, Inc. and SM TEK Group, Inc. agreed to dismiss their litigation with prejudice just 105 days after filing. The case, VoltStar Technologies, Inc. v. Sm Tek Group, Inc. (Case No. 1:23-cv-09529), was filed in the U.S. District Court for the Eastern District of New York on December 28, 2023, and closed on April 11, 2024, without a court ruling on the merits.
At issue was U.S. Reissue Patent RE048794E, directed at USB charging technology, and the accused product was the Bluestone USB Wall Charger. The case terminated through a joint stipulated dismissal under Federal Rule of Civil Procedure 41(a)(1)(A)(ii), with each party bearing its own costs, attorneys’ fees, and expenses — a structure that signals a negotiated resolution rather than a decisive legal victory for either side.
For patent attorneys, IP professionals, and R&D teams operating in the consumer electronics and charging technology space, this case offers instructive lessons about litigation strategy, early resolution, and patent risk management.
The Parties
⚖️ Plaintiff
The plaintiff and patent holder, asserting intellectual property rights in USB charging technology. As a technology licensor and IP rights holder, VoltStar initiated this action to enforce its reissue patent against an alleged infringer in the consumer accessories market.
🛡️ Defendant
A company involved in the distribution or sale of consumer electronics accessories, including the accused Bluestone USB Wall Charger — a product in a highly competitive, commoditized segment of the consumer electronics market.
The Patent at Issue
The asserted patent is U.S. Reissue Patent No. RE048794E (corrected application number US16/209373). Reissue patents are significant procedural instruments: they are issued by the USPTO to correct errors in an already-granted patent, and they maintain the original patent’s priority date while potentially broadening or narrowing claims. The reissue designation signals that VoltStar had previously refined its patent claims — a strategic move that can strengthen enforceability before litigation.

The Verdict & Legal Analysis
Outcome
The case was **dismissed with prejudice** pursuant to a **joint stipulation** under **Fed. R. Civ. P. 41(a)(1)(A)(ii)**. Both parties agreed that each would bear its own costs, attorneys’ fees, and expenses.
Key implications of this dismissal structure:
- With prejudice means VoltStar cannot re-file the same claims against SM TEK Group based on the same accused product and patent. The dismissal is final as to this dispute.
- No damages were awarded or disclosed, and no injunctive relief was entered against SM TEK Group.
- No court ruling on the merits was issued — the patent’s validity and infringement were never adjudicated by the court.
Key Legal Issues
The dismissal without a court ruling on merits highlights strategies for early resolution in patent cases. The joint nature of the stipulation — and the mutual agreement to absorb individual costs — is a hallmark of confidential settlement agreements in patent cases. This forecloses any argument about exceptional case status under 35 U.S.C. § 285, which allows courts to award attorneys’ fees in exceptional patent cases.
The deployment of a reissue patent (RE048794E) in litigation reflects a deliberate prosecution strategy. Patent holders who anticipate enforcement should consider whether reissue proceedings could strengthen claim scope pre-litigation.
