Hanover Prest-Paving v. Eterno Ivica: Paver Pedestal Patents Dismissed With Prejudice
Hanover Prest-Paving filed a three-patent infringement action against Italian manufacturer Eterno Ivica in Pennsylvania’s Middle District, targeting paver pedestal and bi-component self-levelling head technology. The case closed after 648 days with a dismissal with prejudice by agreement of counsel — a resolution that permanently bars Hanover from re-filing the same claims.
Three-Patent Paver Pedestal Dispute Ends in Agreed Permanent Dismissal
Hanover Prest-Paving Co., a Pennsylvania-based paving products company and holder of three patents covering paver pedestal support systems and bi-component self-levelling XL head technology, filed suit against Eterno Ivica S.r.l. — an Italian manufacturer — on November 2, 2023 in the U.S. District Court for the Middle District of Pennsylvania. The complaint asserted infringement of US7918059B2, US8381461B2, and US8438805B2, all directed at engineered systems providing rigid support for pavers in architectural and construction applications.
After 648 days of litigation, the case was terminated on August 11, 2025 when Judge Karoline Mehalchick ordered the action dismissed with prejudice pursuant to agreement of counsel. A dismissal with prejudice is a final adjudication on the merits: Hanover cannot re-file these infringement claims against Eterno Ivica based on the same patents and accused products. The ‘agreement of counsel’ language is consistent with a negotiated resolution — whether a licensing arrangement, design-around undertaking, or commercial settlement — but the specific terms are not publicly disclosed.
The 648-day duration suggests the parties engaged in substantive pre-trial proceedings before reaching resolution, potentially including claim construction briefing or early discovery, which may have clarified the strength of each side’s position. The with-prejudice nature of the dismissal distinguishes this from a purely tactical withdrawal and suggests both sides had incentive to achieve finality. What drove the agreement — royalty rates, design modifications, or broader commercial considerations — remains unknown from the public record.

Dismissed with prejudice by agreement: what the ruling means for both parties
Dismissal with prejudice is a final, permanent bar to re-filing
A dismissal with prejudice operates as a final judgment on the merits. Unlike a without-prejudice dismissal — which preserves the right to re-file — this order permanently extinguishes Hanover’s right to assert these three patents against Eterno Ivica for the same accused conduct. The ‘pursuant to agreement of counsel’ language indicates both parties consented, which is characteristic of a negotiated resolution rather than a unilateral withdrawal.
Permanent claim barHanover forfeits the right to re-litigate — likely received consideration
By agreeing to a with-prejudice dismissal, Hanover permanently surrendered the ability to re-file these infringement claims based on US7918059B2, US8381461B2, and US8438805B2 against Eterno Ivica. Patent holders typically accept this finality only when they have received commercial consideration — such as a licence, royalty, or product modification — making a silent settlement the most commercially plausible explanation, though the public record does not confirm terms.
Likely settled — terms undisclosedEterno Ivica achieves finality — but patent risk persists for third parties
For Eterno Ivica, the with-prejudice dismissal closes the specific litigation exposure in M.D. Pa. and eliminates the risk of re-filed claims on these three patents from this plaintiff. However, the underlying patents remain in force. Any licence or design-around agreed as part of the settlement would govern Eterno Ivica’s ongoing commercial freedom, details of which are not visible in the public record.
Litigation closed — patents survivePaver pedestal sector: three active patents remain enforceable against others
The dismissal resolves only the bilateral dispute between Hanover and Eterno Ivica. US7918059B2, US8381461B2, and US8438805B2 remain active and enforceable against any other manufacturer or distributor of competing paver pedestal or self-levelling head products. Competitors entering this segment — particularly those producing rigid-support paver systems — should treat these patents as live enforcement risks requiring FTO analysis.

Official order — verbatim text
The order’s phrasing — ‘DISMISSED with prejudice, pursuant to agreement of counsel’ — is precise and consequential. ‘With prejudice’ signals finality: the court treats the matter as fully resolved on the merits, foreclosing any future action on these claims between these parties. The ‘agreement of counsel’ qualifier confirms this was not a unilateral or involuntary termination, but a jointly negotiated outcome. No damages figure, royalty rate, or injunctive relief term is memorialised in the public docket, which is typical of commercially negotiated patent resolutions.
US7918059B2, US8381461B2 & US8438805B2 — Paver Pedestal Support Systems
The three asserted patents — US7918059B2, US8381461B2, and US8438805B2 — cover engineered paver pedestal technologies used in elevated architectural flooring and hardscape construction. The patents protect structural and mechanical innovations in systems that provide rigid support for pavers in commercial and residential applications, including bi-component self-levelling XL head assemblies that allow precise height and angle adjustment. All three applications were filed in the 2009–2011 period, indicating a coordinated filing strategy around a product generation.
For the paver pedestal and architectural hardscape sector, this patent family represents a meaningful IP barrier. Elevated paver systems — used extensively in rooftop terraces, plazas, and commercial outdoor spaces — require precise levelling and load-bearing performance, and claims covering the mechanical interaction between pedestal components and self-levelling heads are commercially significant. Any manufacturer offering competing pedestal systems with comparable self-levelling functionality faces non-trivial infringement risk under this family, particularly given Hanover’s demonstrated willingness to enforce.
Should your paver pedestal product be cleared against US7918059B2?
Any company designing, manufacturing, or importing paver pedestal systems — particularly those incorporating bi-component or self-levelling head assemblies — should conduct a freedom-to-operate analysis against this three-patent family. The risk is not hypothetical: Hanover has already pursued litigation to a with-prejudice resolution against a foreign competitor, and all three patents appear to remain in force. Distributors and OEM suppliers in the US market are equally exposed.
PatSnap Eureka’s FTO Search Agent can map your product’s claim landscape against US7918059B2, US8381461B2, and US8438805B2 in hours rather than weeks.

What this case signals for the paver pedestal and architectural hardscape IP landscape
Three active patents, a European defendant, and a with-prejudice settlement — this case has clear implications for hardscape product IP strategy.
With-prejudice settlement signals Hanover is an active patent enforcer
Asserting three patents simultaneously against a foreign manufacturer and securing a with-prejudice resolution is consistent with a deliberate enforcement strategy. Competitors manufacturing or distributing paver pedestal systems in the US market should treat Hanover’s portfolio as an active enforcement risk, not a dormant filing.
Foreign manufacturers face US jurisdiction risk on imported paver systems
Eterno Ivica’s Italian domicile did not prevent M.D. Pa. from asserting jurisdiction. Any non-US manufacturer selling bi-component or rigid-support paver pedestal systems into the US market should assess whether their products intersect with US7918059B2, US8381461B2, or US8438805B2 before distribution agreements are signed.
Hanover v Eterno — key questions answered
A dismissal with prejudice by agreement means both parties jointly requested the court close the case permanently. Hanover cannot re-file these infringement claims against Eterno Ivica based on the same three patents and accused products. It is legally equivalent to a final judgment and typically reflects a negotiated resolution — though the specific terms are not public.
Hanover asserted three patents: US7918059B2, US8381461B2, and US8438805B2. All three cover paver pedestal support systems and related technology, including bi-component self-levelling XL head assemblies used to provide rigid, adjustable support for pavers in architectural and construction applications.
A paver pedestal system is an engineered support structure used to elevate pavers in rooftop terraces, plazas, and outdoor commercial spaces. The mechanical precision required — particularly for load distribution and self-levelling adjustment — creates protectable innovation at the component level. Patents in this space often cover the interaction between the pedestal base, height-adjustment mechanism, and head assembly.
The public record does not indicate a winner in the traditional sense. The case was dismissed with prejudice by agreement, suggesting a negotiated outcome. Hanover permanently relinquished the right to re-file, which patent holders typically accept only in exchange for commercial consideration such as a licence or settlement payment. No damages or injunction were publicly recorded.
The dismissal resolves only the specific litigation between these parties. Whether Eterno Ivica can sell freely depends on any licence or design-around terms agreed as part of the settlement — which are not public. The underlying patents US7918059B2, US8381461B2, and US8438805B2 remain in force and could be asserted against other parties or, under different facts, against Eterno Ivica if new infringement were alleged.
