Google Wins Patent Dispute Over Advertising Funding Model in PTAB Decision
On Tuesday, the U.S. Patent Trial and Appeal Board (PTAB) issued a ruling that clears Google LLC of alleged infringement on BrodTi Inc.’s U.S. Patent No. 11,416,898. The decision, delivered in a final written opinion, found that Google’s Google Ads and AdSense platforms do not violate the patent’s claims, which describe an advertising funding model that eliminates reliance on traditional fundraising systems.
BrodTi filed suit against Google in 2024 in the U.S. District Court, alleging that the company’s advertising services implemented the patented model. The parties agreed to stay the lawsuit while the PTAB considered the claims, a common practice that allows the board to resolve patent questions before any court action proceeds. After a review that included examination of the patent’s text, relevant prior art, and expert testimony, the PTAB rejected multiple claims in the patent.
The board’s analysis centered on the doctrine of obviousness. According to the PTAB decision, the contested claims are unpatentable because earlier innovations made the technology “obvious to the relevant artisan.” The board cited advertising systems and funding mechanisms that were publicly available before the patent’s filing date, such as early pay‑per‑click models and revenue‑sharing arrangements used by web publishers in the early 2000s. The decision concluded that the patent’s claims did not introduce a novel or non‑obvious element beyond what was already known.
For Google, the ruling removes a potential legal barrier to its advertising operations. The company runs the world’s largest online advertising network, with AdSense serving millions of publishers and Google Ads dominating search‑based advertising. By avoiding infringement liability, Google can continue to use its current funding model without the risk of costly damages or injunctions that could disrupt billions of dollars in ad spend.
The case fits into a broader pattern of patent litigation in the advertising technology sector. In recent years, several startups and mid‑size firms have filed suits against major platforms, claiming that proprietary algorithms or funding mechanisms are protected by patents. PTAB decisions that identify prior art often render these claims vulnerable. The BrodTi ruling is a reminder that the bar for patentability in ad‑tech remains high, especially when the alleged invention can be traced back to widely used industry practices.
While the lawsuit remains stayed, the PTAB’s ruling is the last administrative step before any potential judicial review. The parties may still pursue appeals, but the decision establishes the current legal standing. If an appeal is filed, it would likely focus on procedural issues or the PTAB’s interpretation of obviousness rather than new evidence.
The outcome also signals to other firms that drafting claims around well‑established advertising mechanisms requires careful consideration of prior art. The decision underscores the importance of rigorous prior‑art searches and clear differentiation of novel technical contributions when filing patents in this space.
In sum, the PTAB’s decision removes a key legal hurdle for Google’s advertising operations and reaffirms the role of prior art in patent disputes. The ruling may influence how future claims are drafted in the ad‑tech industry and serves as a reference point for companies contemplating litigation against large platform operators. As the legal landscape continues to evolve, the BrodTi case remains a notable example of how administrative patent boards can shape the trajectory of technology competition.
