Kostic & Vandevelde v. Vidal (Fed. Cir. 23-1437) — Appeal Dismissed in 370 Days
Inventors Miodrag Kostic and Guy Vandevelde appealed a USPTO patentability ruling over US8494950B2, a system for exchanging click-through traffic on internet websites, before the Court of Appeals for the Federal Circuit. The appeal was dismissed in 370 days after appellants failed to file the required appendix under Federal Circuit Rule 30(a).
USPTO patentability appeal dismissed for procedural non-compliance
Inventors Miodrag Kostic and Guy Vandevelde filed this appeal at the Court of Appeals for the Federal Circuit on 31 January 2023, challenging a patentability determination by USPTO Director Katherine K. Vidal. The patent at issue, US8494950B2 (application no. US10/411987), covers a system for conducting an exchange of click-through traffic on internet websites — a technology category that has faced sustained validity scrutiny under post-Alice § 101 analysis and prior art challenges at the USPTO.
The appeal was dismissed on 5 February 2024, 370 days after filing. The Federal Circuit’s order is explicit: the appellants failed to file an appendix required by Federal Circuit Rule 30(a) within the permitted time. This is a procedural dismissal for failure to prosecute — the court did not reach the underlying merits of the patentability challenge. The dismissal leaves the USPTO’s underlying patentability ruling intact and effectively unchallenged at the appellate level.
A 370-day window that ends in a procedural dismissal — rather than a substantive ruling — is consistent with cases where appellants lose momentum or resources after filing. The absence of a merits decision means no Federal Circuit guidance was issued on the patentability of click-through traffic exchange systems under this patent. What drove the failure to file the appendix, and whether any further review was sought, remains unknown from the public record.

What Federal Circuit Rule 30(a) requires — and what was missed
Federal Circuit Rule 30(a) mandates that appellants file a joint appendix containing the portions of the record necessary for the court to decide the appeal. Failure to file this document within the prescribed deadline is treated as a failure to prosecute. The court dismissed the petition on this procedural ground alone, without addressing the substantive patentability arguments Kostic and Vandevelde sought to advance.
Failure to prosecuteThe USPTO’s ruling stands — no merits review was conducted
Because the dismissal is procedural rather than on the merits, the Federal Circuit issued no opinion on whether US8494950B2 is patentable. The USPTO Director’s underlying determination remains in effect. This dismissal is not a finding that the patent is invalid or unpatentable — it means the appellate challenge was abandoned. Whether the inventors can pursue further options, such as a new proceeding, depends on the specific USPTO action being appealed and applicable time limits.
USPTO ruling left intactClick-through traffic exchange patents face persistent validity risk
US8494950B2 covers a system for exchanging click-through traffic across internet websites — a category of internet-era business-method patents that has faced heightened invalidity risk since the Supreme Court’s Alice Corp. v. CLS Bank decision. Patents claiming abstract internet traffic or advertising exchange mechanisms have been frequently challenged at the USPTO via inter partes review and ex parte reexamination, making this appeal consistent with a broader pattern of inventors defending earlier-generation web patents.
Post-Alice validity riskProcedural dismissals may signal resource or strategic constraints
When inventors — rather than corporate assignees — prosecute Federal Circuit appeals pro se or with limited counsel continuity, procedural lapses such as missing appendix deadlines are more common. The appellants here were represented by Taft, Stettinius & Hollister LLP, so resource constraints are less obvious, though the reasons for the filing failure are not disclosed. This outcome suggests the appeal may have been abandoned strategically or administratively rather than litigated to a decision.

Stipulation of dismissal — official text
The Federal Circuit’s order is categorical: the petition is dismissed solely because appellants failed to file the Rule 30(a) appendix on time. The phrase ‘failure to prosecute in accordance with the rules’ is standard Federal Circuit language for a procedural default — it carries no implication about the merits of the patentability arguments. For the defendant (USPTO Director Vidal), the effect is a clean win: the underlying agency determination stands unchallenged at the appellate level.
US8494950B2 — Internet Click-Through Traffic Exchange System
US8494950B2, filed under application number US10/411987, protects a system for conducting an exchange of click-through traffic on internet websites. The patent belongs to a category of early internet-era inventions that sought to formalise traffic-sharing and reciprocal linking arrangements between web publishers. These patents were filed in the early 2000s — predating the widespread judicial scrutiny of software and business-method patents that followed the Supreme Court’s 2014 Alice decision — and their claim language often reflects the broader, more abstract drafting conventions of that period.
From a competitive standpoint, US8494950B2 is strategically significant for any company operating in the web traffic exchange, affiliate marketing, or programmatic advertising ecosystem. Even a patent of uncertain validity creates freedom-to-operate risk if it remains technically in force. The unresolved appellate status of the underlying USPTO patentability determination means the patent’s enforceability has not been conclusively settled by a court, making it a continuing watch item for competitors and product teams in this space.
Should your team run an FTO analysis against US8494950B2?
Any company building or operating a platform that facilitates exchanges of web traffic, reciprocal click-through arrangements, or structured traffic-sharing between websites should assess its exposure to US8494950B2. Although the patent’s validity has been challenged at the USPTO, the absence of a Federal Circuit merits ruling means no court has conclusively invalidated the claims. Product teams in affiliate marketing, ad-exchange, and traffic monetisation should not assume the patent is off the table.

What this case signals for internet patent appeals at the Federal Circuit
Procedural dismissals at the Federal Circuit reveal as much about appellate strategy as substantive outcomes do.
Appendix compliance is a hard deadline — non-compliance ends appeals
Federal Circuit Rule 30(a) is strictly enforced. This case confirms that even represented appellants will have their petitions dismissed outright for missing the appendix deadline. IP teams managing USPTO appeal dockets should treat Rule 30 compliance as a threshold risk — not a formality — when evaluating the viability of a Federal Circuit challenge.
No merits ruling means no precedent — the patent’s validity is unresolved
The Federal Circuit’s dismissal leaves US8494950B2’s patentability legally unresolved at the appellate level. Competitors or third parties who might have relied on a merits decision to clarify the patent’s scope or validity must continue to treat it as a live asset unless and until a substantive ruling is issued. This ambiguity is commercially relevant for anyone operating in the click-through traffic or web advertising exchange space.
Miodrag v Katherine — key questions answered
The appeal was dismissed because the appellants, Kostic and Vandevelde, failed to file the appendix required by Federal Circuit Rule 30(a) within the permitted deadline. The Federal Circuit’s order expressly states dismissal was for ‘failure to prosecute in accordance with the rules’ — a procedural dismissal with no ruling on the merits of the patentability dispute.
The patent at issue is US8494950B2, filed under application number US10/411987. It covers a system for conducting an exchange of click-through traffic on internet websites. The appeal challenged a USPTO patentability determination made by Director Katherine K. Vidal.
No. The Federal Circuit dismissed the appeal on procedural grounds — failure to file the required appendix — without reaching the merits of the patentability arguments. The USPTO’s underlying determination remains in effect, but no court has issued a definitive ruling on whether the patent is valid or invalid.
Federal Circuit Rule 30(a) requires appellants to file a joint appendix containing the portions of the record needed for the court to review the appeal. It is a mandatory procedural requirement with strict deadlines. Non-compliance is treated as failure to prosecute and results in dismissal of the appeal, as occurred in this case.
The procedural dismissal leaves US8494950B2’s patentability unresolved at the appellate level. For companies in web traffic exchange, affiliate marketing, or ad-tech, this means the patent technically remains in force pending any further proceedings. Competitors should consider a freedom-to-operate analysis and monitor for continuation applications or new enforcement activity.
