AudienceScience v. Google: When an Ad-Tech Patent Becomes an Abstract Idea
On September 25, 2026, the Federal Circuit affirmed the dismissal of a patent-infringement case over technology for selecting online advertisements. The court held that the asserted claims were directed to the abstract idea of targeting internet users with advertisements to maximize revenue and lacked an inventive concept. It also held that the patent owner forfeited its request for another opportunity to amend the complaint because it had not asked the district court for leave to amend or identified specific new allegations.
Receivership Estate of AudienceScience Inc. v. Google LLC is nonprecedential, so it does not create a new binding rule. Its reasoning is nevertheless useful for software and internet businesses. It shows how patent eligibility can turn on three connected documents: the claims, the specification, and—once litigation begins—the complaint.
What the AudienceScience Patents Claimed
AudienceScience asserted three related patents sharing a common specification and claiming priority to December 2004. The patents concerned selecting an advertising message for a publisher’s webpage based on both the page’s context and the user’s browsing history.
The representative claim received a page request, added the page to the user’s request history, mapped pages to keywords, used those keywords to identify advertising messages, assigned each candidate advertisement a weighting reflecting revenue performance, and selected an advertisement according to those weightings. A computing system then returned the requested page with an instruction to display the selected advertisement.
AudienceScience sued Google and YouTube for infringement. After transfer to the Northern District of California, Google moved for judgment on the pleadings under Federal Rule of Civil Procedure 12(c). The district court held the claims ineligible under 35 U.S.C. § 101 and dismissed the case without leave to amend. The Federal Circuit affirmed.
A Computerized Business Objective Remained an Abstract Idea
The court applied the two-step framework from Alice Corp. v. CLS Bank. At step one, a court asks whether a claim is directed to a patent-ineligible concept such as an abstract idea. If so, step two asks whether the claim contains an inventive concept that transforms the claim into a patent-eligible application.
The Federal Circuit characterized the AudienceScience claims as directed to targeting internet users with advertisements to maximize revenue. That characterization was tied to the claim language: the method collected information associated with the user and webpage, identified matching advertisements, assigned weightings based on revenue performance, and selected an advertisement for display.
The fact that the process operated online did not make the underlying problem technological. The court distinguished claims addressing a problem unique to computer networks from claims that apply a familiar business objective in an internet environment. Selecting effective advertising based on customer information and prior performance was analogous, in the court’s view, to targeting print or television advertisements.
This is an important line for applicants. A claim does not become eligible merely because the information exists in a database, the process happens quickly, or the method would be impractical without computers. A patent application should identify the technical obstacle presented by the computing environment and explain the particular mechanism used to overcome it. Tucker Law’s patent application practice focuses on connecting those technical details to the written description and claims.
A Sequence of Steps Is Not Necessarily a Specific Technological Solution
AudienceScience argued that its claims recited a granular methodology rather than a desired result. The claims did include multiple steps: updating a page-request history, identifying keywords, finding advertisements, weighting them, and selecting one for display. The Federal Circuit still found the claims insufficiently specific.
The key question was not simply whether the claim contained verbs or an ordered workflow. The court focused on whether the claim recited how the asserted improvement was technologically achieved. It compared the claims to earlier targeted-advertising claims that identified search results, found associated advertisements, correlated the information, and displayed an advertisement without specifying a technological improvement to computer functionality.
The performance-score limitation added particularity, but it remained directed to collecting data and tailoring advertisements to maximize revenue. The claim said that the weighting reflected prior revenue generation; it did not provide a more specific technical mechanism for performing the weighting or solve a computer-specific problem.
By contrast, the court discussed eligible software cases involving concrete techniques: coordinated network monitoring to detect intrusions, behavior-based virus scanning, and specific rules for automated computer animation. The lesson is not that software must claim source code or one narrow embodiment. It is that a claim framed as an improvement should recite features that actually perform the asserted technical improvement.
The Specification’s Description of Conventional Methods Mattered
At Alice step two, AudienceScience relied on combining page context and browsing history and on using performance scores and weightings. The court held that neither supplied an inventive concept.
The common specification described page-context targeting and user-history targeting as conventional approaches. Combining them produced more personalized advertising, but personalization was part of the abstract objective the court had already identified. An ineligible concept cannot become the inventive concept merely by being performed more effectively.
The claimed performance score did not change the result. The claims stated that advertisements received weightings reflecting revenue performance, but did not explain in greater technical detail how the scoring mechanism worked. The court also noted that the complaint contained no allegations explaining why this feature was an inventive concept, and AudienceScience pointed to nothing in the specification supplying that missing explanation.
Patent drafters should be deliberate when using words such as “conventional,” “known,” or “routine.” Accurate background statements are necessary, but an application should clearly separate the prior approach from the claimed technical contribution. The specification should explain the technical problem, the mechanism that solves it, why the mechanism changes computer or network operation, and which alternatives can implement the improvement. Tucker Law’s broader patent practice connects this disclosure work to prosecution and eventual enforcement.
The Complaint Became Part of the Eligibility Record
The litigation portion of the opinion is as significant as the claim analysis. Patent eligibility is a legal question, but the Federal Circuit has recognized that Alice step two may involve factual issues, including whether a claim element or ordered combination was well-understood, routine, and conventional. Specific factual allegations can therefore matter at the pleadings stage when they are consistent with the patent.
AudienceScience’s complaint did not allege an inventive concept. More importantly, when Google moved for judgment on the pleadings, AudienceScience did not ask for leave to amend, attach a proposed amended complaint, explain that it could cure a pleading deficiency, or move for reconsideration after judgment. On appeal, it argued generally that additional allegations could have placed the patent language in context.
The Federal Circuit held that this was too late. Because AudienceScience had taken no steps in the district court to indicate that it wanted to amend—and still did not specify what it would add—the court held that the amendment argument was forfeited. It therefore did not decide whether amendment actually would have been futile.
That procedural distinction matters. The holding was not that every complaint dismissed under Section 101 must be dismissed with prejudice. It was that a litigant cannot remain silent in the district court and then expect the appellate court to supply an amendment opportunity without a concrete proposal.
What Patent Owners Should Plead and Preserve
A patent-infringement complaint should do more than identify the patents, accused products, and infringement theory when an early eligibility challenge is foreseeable. Without turning the complaint into an expert report, the patent owner should consider allegations grounded in the specification that explain:
- the technical problem existing in the prior systems;
- the claim limitations that provide the specific solution;
- how those limitations improve computer, network, device, or data-processing operation;
- why the claimed combination was not merely a routine use of generic technology; and
- where the patent describes and supports those assertions.
Those allegations must remain tethered to the patent. Litigation cannot repair a specification that never describes the supposed technical improvement, and a complaint cannot rewrite functional claim language into a mechanism the claims do not recite.
If the court finds the pleading deficient, the patent owner should request leave to amend promptly and explain what the amendment would add. Depending on the procedural rules and posture, that may include providing a proposed amended complaint or seeking reconsideration. The exact step is governed by the applicable regional circuit and district-court rules, so procedural preservation should be addressed before judgment rather than saved for appeal.
Tucker Law’s patent litigation practice evaluates the claims, specification, prosecution history, accused technology, and pleadings as one connected record. Out-of-state counsel can also coordinate Florida proceedings through the firm’s federal IP local counsel practice.
What Accused Infringers Should Take From the Decision
AudienceScience confirms that a Section 101 defense may be resolved on a Rule 12(c) motion when the pleadings and patent present no material factual dispute requiring later development. Accused infringers should identify whether the claims recite a technological mechanism or primarily automate data collection, evaluation, matching, ranking, or commercial decision-making with generic computers.
An early motion is not automatic. Eligibility disputes may present factual questions, and a well-supported complaint can make dismissal at the pleadings stage inappropriate. A defendant also should consider claim construction, the specification, prosecution statements, representative-claim disputes, and whether a ruling would dispose of all asserted claims. Early motion practice should serve the case strategy rather than merely front-load expense.
The Decision Should Not Be Read as a Ban on Ad-Tech Patents
The opinion is nonprecedential and claim-specific. It does not hold that every advertising, recommendation, personalization, or analytics invention is an abstract idea. The court itself distinguished claims that recite a specific solution to a technological problem.
Nor does the opinion reduce eligibility to the novelty of the business idea. Section 101 asks whether the claims are directed to eligible subject matter and contain the required inventive concept. Novelty and nonobviousness are separate requirements. A new commercial strategy can still be abstract, while a properly claimed technical implementation may present a different eligibility case.
The Federal Circuit’s recent eligibility decisions reinforce a common drafting theme: the technical improvement should be visible in the claim, supported in the specification, and explained consistently when the patent is litigated. TuckerUp’s analysis of the split eligibility ruling in Constellation Designs v. LG provides a complementary example of how different claims in the same case can receive different Section 101 outcomes.
The Bottom Line
AudienceScience v. Google connects patent drafting to litigation procedure. The asserted ad-targeting claims described a commercial result implemented with generic computing steps, while the specification and complaint supplied no specific technological mechanism that changed the eligibility analysis. When the complaint was dismissed, the patent owner also failed to request amendment in the district court.
