Memory Technologies v. PNY Technologies: 8-Patent Flash Memory Dispute Ends in Dismissal With Prejudice
Memory Technologies LLC filed a patent infringement action against PNY Technologies Inc. in Delaware, asserting 8 patents covering flash memory architecture, multimedia card interfaces, and power management. After 590 days of litigation, the parties stipulated to dismiss all claims with prejudice — ending Memory Technologies’ enforcement rights permanently.
Eight-Patent Flash Memory Campaign Ends in Bilateral Dismissal
On 28 March 2023, Memory Technologies LLC filed suit against PNY Technologies Inc. in the District of Delaware before Judge William C. Bryson, asserting infringement of eight U.S. patents spanning flash memory extended utilization, multimedia card (MMC) interface methods, memory addressing systems, and power consumption determination. The asserted portfolio — including two reissue patents (USRE045486E and USRE045542E) — reflects a broad, multi-technology enforcement strategy targeting PNY’s memory card and flash storage product lines.
The case closed on 7 November 2024 via a stipulated dismissal under Fed. R. Civ. P. 41(a)(2) and (c), approved by the Court. Critically, all of Memory Technologies’ claims were dismissed with prejudice, meaning it is permanently barred from re-asserting those claims against PNY on the same patents. PNY’s counterclaims — likely invalidity or non-infringement defenses — were dismissed without prejudice as moot, preserving PNY’s ability to raise them if the patents resurface in future litigation.
A dismissal with prejudice after 590 days — without a public trial or damages award — suggests the parties reached a private resolution, though no settlement terms are disclosed in the public record. The extended timeline before stipulation, combined with the presence of two reissue patents and a nine-attorney plaintiff team, suggests substantive claim construction or IPR activity may have influenced the outcome. Whether any license or payment changed hands remains unknown from the public record.

Stipulated dismissal with prejudice: what the Rule 41 order means for both parties
Rule 41 stipulated dismissal: a permanent bar on re-filing
Under Fed. R. Civ. P. 41(a)(2) and (c), both parties jointly moved to dismiss. The ‘with prejudice’ designation on plaintiff’s claims operates as an adjudication on the merits — Memory Technologies cannot re-assert these specific claims against PNY under the same patents. Defendant’s counterclaims were dismissed without prejudice as moot, meaning they were not decided on the merits and could theoretically be revived in new proceedings.
Final on the merits for plaintiff claimsMemory Technologies forfeits right to re-sue PNY on these patents
A dismissal with prejudice is the most defendant-favorable outcome short of a court judgment. Memory Technologies permanently surrendered its infringement claims against PNY under all eight asserted patents. This outcome is consistent with a confidential license or settlement payment — but the public record does not confirm any consideration changed hands. It could equally reflect a litigation cost calculus that favoured exit over continued prosecution.
Claims extinguished against PNYPNY’s counterclaims survive without prejudice — a defensive reserve
PNY’s counterclaims — most likely invalidity or declaratory non-infringement — were dismissed without prejudice as moot. This is standard when the affirmative claims driving the dispute disappear. PNY retains the ability to assert those invalidity arguments if Memory Technologies were ever to re-assert the patents against a third party or in a different forum. The each-party-bears-own-costs provision also suggests neither side extracted a clean concession.
PNY’s invalidity defenses preservedEight flash memory patents remain live against the broader market
The dismissal resolves the dispute only between these two parties. Memory Technologies’ portfolio — covering MMC interfaces, extended flash memory utilization, and power management — remains enforceable against other market participants. Competing flash storage vendors, memory card integrators, and OEMs incorporating similar architectures should treat these patents as active enforcement risks. The reissue patents in the portfolio (USRE045486E, USRE045542E) suggest the claims were broadened post-grant, potentially expanding their coverage.

Official order — verbatim text
The stipulation’s precise language — plaintiff claims dismissed ‘with prejudice,’ defendant counterclaims dismissed ‘without prejudice as moot’ — reflects a carefully negotiated procedural asymmetry. The with-prejudice designation on Memory Technologies’ claims carries res judicata effect, permanently barring re-litigation of these specific claims between these parties. The mootness dismissal of PNY’s counterclaims avoids any merits ruling on patent validity, leaving the portfolio intact and potentially enforceable against others. The absence of fee-shifting under 35 U.S.C. § 285 suggests neither party sought — or could support — an exceptional case finding.
US11182079B2 and portfolio — flash memory architecture and MMC interface patents
The eight asserted patents cover a technically diverse but commercially cohesive set of flash memory innovations: extended storage utilization architectures (US11182079B2, US10540094B2), multimedia card interface protocols (US7565469B2), memory card addressing systems (US9063850B2, US9367486B2), flash memory management methods (US8307180B2), and power consumption determination (USRE045486E, USRE045542E). The two reissue patents indicate the original claims were amended post-grant — a process that can broaden claim scope to capture products not covered by the original filings, and a signal that enforcement coverage was deliberately extended.
Strategically, this portfolio targets foundational aspects of how flash memory devices are addressed, managed, and interfaced — functions present across a wide range of consumer and enterprise storage products including SD cards, USB drives, SSDs, and embedded storage. The breadth of the portfolio, combined with the use of reissue patents, is consistent with a licensing or assertion strategy designed to cover multiple product categories simultaneously. For vendors in the flash memory supply chain, each patent represents a discrete enforcement vector that warrants independent FTO assessment.
Should your team run an FTO against this 8-patent flash memory portfolio?
Any company designing, manufacturing, or selling products with flash memory interfaces, MMC-compatible storage, or embedded power management systems should consider these eight patents a live risk. The dismissal with prejudice resolves only the PNY dispute — Memory Technologies retains full enforcement rights against the broader market. R&D teams working on memory controller firmware, card interface protocols, or extended flash utilization architectures face the highest exposure. A pre-product FTO analysis could identify design-around opportunities before a complaint is filed.

What this case signals for the flash memory and storage IP landscape
A quickly-resolved eight-patent campaign in Delaware signals active monetisation of legacy flash memory IP — with implications for any company in the memory card supply chain.
Reissue patents signal intentionally broadened claims — map your exposure
Two of the eight asserted patents are reissues (USRE045486E, USRE045542E), indicating the original claims were amended post-grant to extend coverage. Reissue patents are a common tool for patent assertion entities to re-scope claims around competitor products. Any company selling MMC-compatible or flash memory products should assess whether broadened reissue claims cover current product architectures.
Each-party-bears-costs provision rules out a clear litigation winner
The mutual cost-bearing stipulation is consistent with either a confidential license payment to Memory Technologies or a mutual acknowledgement that continued litigation was uneconomic for both sides. It does not, on its own, indicate which party held the stronger legal position. Companies monitoring this docket should not assume PNY prevailed on the merits.
Memory v PNY — key questions answered
Memory Technologies LLC filed a patent infringement action against PNY Technologies Inc. in the District of Delaware on 28 March 2023, asserting eight patents covering flash memory and MMC interface technologies. The case closed on 7 November 2024 via a stipulated dismissal under Rule 41(a)(2): all of Memory Technologies’ claims were dismissed with prejudice, and PNY’s counterclaims were dismissed without prejudice as moot. Each party bears its own costs.
A dismissal with prejudice operates as a final adjudication on the merits. Memory Technologies is permanently barred from re-filing the same infringement claims against PNY Technologies under the same eight patents. However, the patents remain enforceable against other defendants — the dismissal does not invalidate or cancel the patents.
Memory Technologies asserted eight U.S. patents: US11182079B2, USRE045486E, US9063850B2, US7565469B2, US8307180B2, USRE045542E, US10540094B2, and US9367486B2. The portfolio covers extended flash memory utilization, multimedia card interface methods, memory addressing systems, and power consumption determination for electronic devices.
USRE045486E and USRE045542E are reissue patents, meaning the USPTO granted amended versions of the original patents post-grant. Reissues can broaden or correct original claims and are commonly used in enforcement strategies to ensure claim language captures commercial products more precisely. Broadened reissue claims can extend coverage to products not reached by the original patent, increasing the risk profile for competitors.
No. The stipulated dismissal with prejudice resolves only the dispute between Memory Technologies and PNY Technologies. All eight patents remain active and enforceable against other parties. Companies selling MMC-compatible storage, flash memory controllers, or devices implementing similar addressing and interface methods should treat this portfolio as an active enforcement risk and consider freedom-to-operate analysis.
