Imberatek LLC v. Apple Inc. — 9-Patent SoC Packaging Dispute Settled in 63 Days
Imberatek LLC, a patent-assertion entity, filed suit against Apple in the Northern District of California asserting nine patents covering semiconductor device packaging technology across Apple’s entire A-series and M-series SoC portfolio. The case resolved by confidential settlement and was dismissed with prejudice in just 63 days — an unusually compressed timeline for multi-patent litigation of this technical scope.
Rapid settlement ends broad semiconductor packaging assault on Apple
Filed on 4 March 2025 before Judge Richard Seeborg in the Northern District of California, Imberatek LLC’s complaint targeted virtually every Apple A-series chip (A12 through A17 Pro) and M-series processor (M1 through M3 Max), spanning iPhones, iPads, MacBooks, Mac Studios, Mac Pros, and Vision Pro. The nine asserted patents — including US11071207B2, US7732909B2, US8368201B2, US7989944B2, US9107324B2, US8238113B2, US8222723B2, US7609527B2, and US11716816B2 — collectively cover semiconductor device packaging architectures involving stacked components, insulating layers, and conductive interconnects.
On 6 May 2025, just 63 days after filing, the parties jointly announced to the court that they had reached a settlement. Judge Seeborg entered an order dismissing all claims with prejudice, with each side bearing its own attorneys’ fees, costs, and expenses. A dismissal with prejudice is a final adjudication on the merits: Imberatek is permanently barred from reasserting the same claims against Apple on the same patents, and Apple receives no ongoing judicial protection beyond that preclusion.
A 63-day resolution is notably swift for a nine-patent, multi-product infringement action in N.D. California, where discovery alone typically takes far longer to commence. The speed suggests either pre-filing settlement negotiations were already advanced, or Apple moved rapidly toward a commercial resolution rather than engaging in costly claim-construction litigation across nine patents and dozens of SoC generations. The financial terms of any settlement remain confidential and are not reflected in the public record.

Dismissed with prejudice: what the settlement order means for both parties
Dismissal with prejudice forecloses future suit on these patents
A dismissal with prejudice, entered pursuant to the parties’ settlement announcement, operates as a final judgment on the merits. Imberatek cannot refile the same infringement claims against Apple on any of the nine asserted patents. This is the strongest form of claim closure available short of a full trial verdict, and it is typically the outcome Apple’s counsel would have required before agreeing to settle.
Res judicata appliesImberatek obtains confidential value — then surrenders its litigation position
By accepting a with-prejudice dismissal, Imberatek has permanently relinquished its right to pursue Apple on these nine patents. PAEs typically accept this structure only when compensated — suggesting a licensing payment or other consideration was exchanged, though no financial terms appear in the public record. Imberatek retains the patents and may assert them against other parties in the semiconductor packaging space.
Terms undisclosedApple secures claim closure across its entire SoC portfolio
Apple’s A-series and M-series chips — the engines of its entire hardware lineup — are effectively cleared from this specific patent threat. The with-prejudice structure means Imberatek cannot repackage these claims in a future action. Apple’s legal team at Fish & Richardson secured this closure without any fee-shifting, and the case did not proceed to claim construction, preserving Apple’s strategic positions on these packaging technologies.
Full portfolio clearedNine semiconductor packaging patents remain live against the broader market
Imberatek’s portfolio — covering stacked semiconductor packaging, insulating layers, and conductive interconnects — is still enforceable against other chipmakers and device manufacturers. Companies relying on similar SoC-in-package or 3D-stacking architectures (including Qualcomm, MediaTek, Samsung, and others) should treat this case as an early signal of Imberatek’s enforcement posture. The 63-day settlement timeline suggests the patents are commercially viable licensing assets.

Official order — verbatim text
The court’s order adopts the precise language of the parties’ joint announcement: all claims for relief are dismissed with prejudice, with fee allocation explicitly symmetric — each party bears its own costs. The with-prejudice formulation is legally significant: it operates as a final adjudication, triggering res judicata and preventing Imberatek from relitigating the same patent claims against Apple. The absence of fee-shifting indicates neither party sought nor obtained an ‘exceptional case’ designation under 35 U.S.C. § 285. No royalty rate, license term, or monetary consideration appears in the public record.
US11071207B2 — semiconductor device packaging and SoC stacking architecture
The nine asserted patents — spanning application dates from the mid-2000s through the early 2020s — collectively protect architectures for semiconductor device packages in which multiple semiconductor components are arranged vertically, separated by insulating materials, and connected by conductive pathways. US11071207B2 and US11716816B2 represent the most recently issued patents in the portfolio, suggesting continued prosecution activity to capture evolving chip packaging methods. The technical domain — heterogeneous integration and 3D stacking — is central to how modern SoCs achieve performance-per-watt efficiency.
Advanced packaging is no longer a manufacturing afterthought: it is a primary competitive differentiator for Apple Silicon, Qualcomm Snapdragon, and comparable platforms. Patents in this space carry meaningful licensing leverage because the underlying architectures are deeply embedded in foundry-level production processes, making design-arounds technically and commercially costly. Imberatek’s portfolio, which tracks the progression from early chip-stacking methods (US7609527B2, filed 2007) to current-generation integration (US11071207B2, filed 2020), is structured to cover incremental improvements across chip generations — a classic portfolio-bracketing strategy.
Should you run an FTO against US11071207B2 and Imberatek’s packaging portfolio?
Any company designing, manufacturing, or importing products incorporating stacked SoC packaging — including 3D-integrated chiplets, package-on-package (PoP) designs, or heterogeneous integration modules — should treat Imberatek’s nine-patent portfolio as an active enforcement risk. The claims cover semiconductor components arranged on top of each other with insulating materials between them and conductive connections, language broad enough to implicate widely used advanced packaging formats across mobile, PC, and datacenter chip categories.
PatSnap Eureka’s FTO Search Agent can map each of the nine Imberatek patents against your product’s packaging architecture, identify claim elements most likely to read on your specific implementation, and surface prior art or design-around pathways. Given that Imberatek has already demonstrated willingness to assert these patents against the world’s largest chipmaker — and resolved that action with apparent commercial success — proactive FTO analysis is the lower-cost alternative to reactive litigation defence.

Portfolio viewWhat this case signals for the semiconductor packaging IP landscape
A nine-patent broadside against Apple’s entire SoC lineup — resolved in 63 days — sends clear signals to chipmakers and device OEMs about Imberatek’s enforcement strategy.
63-day resolution suggests pre-filing leverage, not litigation attrition
When a multi-patent case against a defendant of Apple’s litigation resources closes in 63 days, it typically signals one of two dynamics: pre-filing licensing dialogue that was close to resolution, or a portfolio with genuine claim-construction risk that Apple preferred to monetize quietly. Either way, Imberatek appears to have extracted value efficiently — a model other PAEs in the semiconductor packaging space are likely to study.
Nine-patent breadth signals portfolio licensing posture, not targeted enforcement
Asserting nine patents across A12 through M3 Max — covering essentially every Apple silicon product of the past six years — is consistent with a licensing-first strategy designed to maximise royalty base. The asserted patents span multiple application numbers and issuance dates, suggesting Imberatek has deliberately assembled a portfolio that tracks the evolution of advanced chip packaging. Companies with similar SoC stacking architectures should audit their exposure now.
Imberatek’s remaining portfolio creates measurable risk for Qualcomm, MediaTek, and Samsung
With Apple cleared, Imberatek’s nine patents — covering stacked semiconductor components with insulating and conductive layers — remain squarely applicable to 3D-stacked SoC architectures used in competing mobile and PC chipsets. The claims as written are broad enough to implicate heterogeneous integration packaging used across the industry. An FTO audit against US11071207B2 and US11716816B2 (the two most recently issued patents) is the recommended first step.
N.D. Cal. venue choice signals Imberatek’s confidence in its claim construction position
Filing in N.D. California — Apple’s home district, known for sophisticated patent judges — rather than W.D. Texas or D. Delaware suggests Imberatek was prepared for rigorous claim construction scrutiny. That confidence, combined with the rapid settlement, suggests the asserted claims may be relatively well-defined and difficult to design around. IP teams at competing chipmakers should treat these patents as litigation-ready, not merely licensing threats.
Imberatek v Apple — key questions answered
The case was dismissed with prejudice on 6 May 2025 following a confidential settlement. The court ordered each party to bear its own attorneys’ fees, costs, and expenses. No financial terms of the settlement appear in the public record.
Imberatek asserted nine U.S. patents: US11071207B2, US7732909B2, US8368201B2, US7989944B2, US9107324B2, US8238113B2, US8222723B2, US7609527B2, and US11716816B2. The patents collectively cover stacked semiconductor device packaging architectures involving insulating and conductive interconnect layers.
Imberatek accused Apple’s A12, A12X, A12Z, A13, A14, A15, A16, and A17 Pro SoCs, as well as the entire M-series processor lineup (M1 through M3 Max), spanning iPhones, iPads, MacBooks, iMacs, Mac Studios, Mac Pros, Mac Minis, Apple TV 4K, and Vision Pro.
A dismissal with prejudice is a final adjudication on the merits. Imberatek is permanently barred from reasserting the same patent claims against Apple on the nine asserted patents in this action. The doctrine of res judicata applies. Imberatek retains ownership of the patents and may assert them against other parties.
The public record does not disclose the reasons for the rapid resolution. The 63-day timeline suggests pre-filing settlement dialogue may have been underway before the complaint was filed, or that Apple’s legal team moved quickly toward a commercial resolution rather than engaging in extended claim-construction proceedings across nine patents. Both outcomes are consistent with PAE litigation dynamics in N.D. California.
