Georgia Tech v. Murata Electronics: LCP Patent Case Stayed for USPTO Reexamination
Georgia Tech Research Corporation filed suit against Murata Electronics North America alleging infringement of US7489914B2, a patent covering multi-layer liquid crystal polymer (LCP) technology embodied in Murata’s MetroCirc product line. The Northern District of Georgia stayed all deadlines pending a USPTO ex parte reexamination — a strategic pivot that leaves the case’s substantive outcome unresolved after 374 days.
LCP Patent Dispute Halted by USPTO Reexamination Gambit
Georgia Tech Research Corporation, the technology commercialisation arm of the Georgia Institute of Technology, filed this patent infringement action on 17 November 2024 in the Northern District of Georgia before Judge J. P. Boulee. The suit targets Murata Electronics North America, Inc., the U.S. subsidiary of Japanese electronics giant Murata Manufacturing, over its MetroCirc multi-layer liquid crystal polymer (LCP) substrate product. The asserted patent, US7489914B2, claims priority to application number US11/114733 and covers advanced LCP-based circuit architectures relevant to high-frequency and miniaturised electronic modules.
Before substantive proceedings advanced, Murata moved to dismiss the complaint and simultaneously triggered a USPTO ex parte reexamination of the asserted patent. On 26 November 2025, the court ordered a full stay of all case deadlines pending the outcome of that reexamination, while denying Murata’s motion to dismiss without prejudice — meaning the dismissal arguments remain live and may be renewed once the stay is lifted. The stay represents a significant procedural win for Murata: it halts litigation costs and places the patent’s validity squarely before the USPTO before any court merits determination.
The 374-day elapsed period reflects the rapid trajectory from filing to stay — consistent with a defendant who moved aggressively to invoke patent office proceedings as a litigation management tool. What drove the court’s willingness to stay is not entirely clear from the public record, but courts in this circuit routinely grant stays when a reexamination is pending and no trial date has been set. Whether the USPTO will confirm, amend, or cancel claims in US7489914B2 will be decisive; the outcome will either reinvigorate Georgia Tech’s infringement case or substantially weaken its enforceability position.
Filing to Case Stayed in 374 days
374 days elapsed; case remains stayed — substantive proceedings paused pending USPTO EPR outcome
Case stayed: what the USPTO reexamination order means for both parties
A stay pending EPR freezes litigation without resolving the merits
When a court stays litigation pending a USPTO ex parte reexamination, all court deadlines — discovery, claim construction, dispositive motions — are suspended. The patent office takes over validity analysis first. The stay here was ordered alongside a denial of Murata’s motion to dismiss ‘without prejudice,’ meaning the court has not ruled on any substantive argument; it has simply paused the forum. Reexaminations can take one to three years and may result in claim cancellation, amendment, or confirmation.
All deadlines stayedGeorgia Tech faces USPTO scrutiny before its infringement case can proceed
For Georgia Tech Research Corporation, the stay creates uncertainty. If the USPTO cancels or narrows claims during reexamination, the infringement case weakens or collapses entirely before returning to court. Georgia Tech retains the right to participate in the reexamination and submit arguments to preserve claim scope, but it cannot advance its damages or injunction theories while the stay is in force. The denial of the dismissal motion without prejudice does preserve litigation optionality once the stay lifts.
Enforcement pausedMurata buys time and shifts the battleground to the USPTO
Murata’s strategy — filing both a motion to dismiss and triggering an ex parte reexamination — produced the outcome defendants typically seek: removal of the case from active litigation. EPR proceedings are ex parte, meaning Murata’s involvement is limited after initiation, but if the USPTO issues a rejection or cancels claims, Murata benefits substantially in the district court. The motion to dismiss remains available to renew, preserving a second line of defence on non-validity grounds once the stay lifts.
Litigation deferredLCP substrate IP enforcement risk remains elevated but unresolved
Multi-layer LCP technology is strategically critical for high-frequency 5G modules, antenna-in-package designs, and miniaturised RF components — a market in which Murata is a dominant supplier. The stay leaves the IP landscape uncertain for competitors and customers of MetroCirc products. Companies designing around or licensing LCP substrate patents should monitor the USPTO reexamination docket closely; confirmed claims would signal heightened enforcement risk across the sector.

Official order — verbatim text
The court’s order is procedural rather than substantive: it reflects a judicial determination that the pending USPTO ex parte reexamination creates sufficient questions about patent validity to justify suspending litigation rather than risking inconsistent outcomes between the court and the patent office. The denial of the motion to dismiss ‘without prejudice’ is significant — it signals the court declined to evaluate Murata’s dismissal arguments on the merits at this stage, preserving them for renewal. No infringement finding, validity ruling, or damages determination has been made.
US7489914B2 — Multi-layer liquid crystal polymer circuit architecture
US7489914B2, filed under application number US11/114733, protects multi-layer liquid crystal polymer (LCP) circuit architectures — a fabrication technology enabling high-frequency signal integrity, low moisture absorption, and miniaturisation in advanced electronic packages. LCP substrates are particularly valued in RF and millimetre-wave applications where conventional FR4 or ceramic materials underperform. The patent’s claims, if confirmed through reexamination, cover structural and compositional aspects of how LCP layers are integrated in multi-layer circuit configurations.
Georgia Tech’s assertion of this patent against Murata’s MetroCirc product line reflects the strategic importance of LCP technology in next-generation wireless modules. Murata is among the world’s largest passive component and module suppliers; its MetroCirc platform targets high-frequency, miniaturised module applications directly relevant to 5G infrastructure and consumer devices. A confirmed and enforceable US7489914B2 would represent meaningful leverage over a large segment of the LCP substrate supply chain, creating licensing pressure not only for Murata but for downstream OEMs relying on similar architectures.
Should you run an FTO against US7489914B2?
Any R&D or product team developing multi-layer LCP substrates, antenna-in-package modules, or high-frequency RF circuits — particularly those incorporating LCP-based multi-layer architectures — should treat US7489914B2 as a live freedom-to-operate risk. The USPTO ex parte reexamination means the claim scope may shift, but until reexamination concludes, the patent remains in force. Products entering commercial production or supply agreements during the stay period carry enforcement exposure if claims are confirmed unchanged.
PatSnap Eureka’s FTO Search Agent can map your product’s LCP layer stack and circuit architecture against the claim language of US7489914B2 in real time, flagging literal and doctrine-of-equivalents risk. Eureka also monitors the USPTO reexamination docket, alerting your team to office actions, claim amendments, and final determinations — so you can update your FTO analysis dynamically as the patent’s scope evolves rather than relying on a static point-in-time assessment.

What this case signals for the LCP and RF substrate IP landscape
A university patent holder vs. a tier-one component supplier — and the USPTO becomes the first real battleground.
Ex parte reexamination is now a first-strike defensive tool in component IP disputes
Murata’s rapid EPR filing before substantive litigation advanced illustrates how defendants in component-level patent cases deploy reexamination offensively. Patent teams at RF and substrate manufacturers should audit their key products against pending university IP portfolios and assess EPR candidacy proactively rather than reactively.
University patent enforcement carries distinct risk — licensing pressure without commercial reciprocity
Georgia Tech Research Corporation is a non-practising entity in the commercial sense: it does not manufacture components and cannot be countersued for infringement. Defendants in university patent cases lack the cross-licence leverage common in commercial disputes, making early validity challenge — as Murata pursued — the primary defence lever available.
Georgia v Murata — key questions answered
The case is stayed. On 26 November 2025, the Northern District of Georgia ordered all deadlines stayed pending the outcome of a USPTO ex parte reexamination of the asserted patent, US7489914B2. Murata’s motion to dismiss was denied without prejudice and may be renewed once the stay is lifted. No substantive merits ruling has been issued.
A denial without prejudice means the court did not evaluate the motion’s substantive arguments — it simply declined to rule while the stay is in effect. Murata retains the right to refile the same or revised motion to dismiss once the USPTO reexamination concludes and the stay is lifted. The denial carries no binding effect on the merits of those arguments.
US7489914B2, assigned to Georgia Tech Research Corporation, covers multi-layer liquid crystal polymer (LCP) circuit architectures used in high-frequency electronic packages. Murata’s MetroCirc product is a multi-layer LCP substrate platform targeting RF and millimetre-wave module applications. Georgia Tech alleges the MetroCirc architecture falls within the scope of the patent’s claims.
An ex parte reexamination (EPR) initiated at the USPTO places patent validity before the patent office before — or instead of — a court determination. Courts frequently stay district court cases when an EPR is pending to avoid inconsistent validity rulings. If the USPTO cancels or narrows claims, Georgia Tech’s infringement case weakens or ends; if claims are confirmed, litigation typically resumes with a stronger patent presumption of validity.
If US7489914B2 survives reexamination with its claims intact, any manufacturer producing multi-layer LCP substrates with similar architectures — particularly for 5G, Wi-Fi 6E, or antenna-in-package applications — could face infringement exposure. The case signals that Georgia Tech is actively enforcing this portfolio, and confirmed claims would likely trigger licensing demands beyond Murata. Companies should conduct FTO analysis against the confirmed claim set before the stay lifts.
