It is a landmark legal case that AccuSearch Technologies LLC has put forward against Google LLC, addressing the very center of the technology giant's business—its search engine feature. The suit, which was lodged on April 28, 2025, in the Delaware District Court, has case number 1:25-cv-00514 and is listed as open.
The lawsuit charges Google with 4 patents held by AccuSearch, which deal with annotation of internet search results, filtering of internet search results, and serving advertisements on internet search results, respectively. AccuSearch asserts that its patented technologies are employed without permission within Google Search Engine Products and Services, specifically the manner in which Google serves up search queries, displays search results, and delivers advertisements according to search term constituents.
Patents at the Center of the Suit
The 4 patents listed in the lawsuit are:
1. U.S. Patent No. 11,100,184 – Annotation, filtering, and advertising of internet search results with regard to search term elements
2. U.S. Patent No. 10,585,959 – Annotation and filtering of internet search results for absent search terms
3. U.S. Patent No. 10,867,001 – Annotation of internet search results for search term elements on referenced webpages and descendant webpages
4. U.S. Patent No. 11,971,937 – Annotation, filtering, and advertisement of internet search results based on search term components
All these patents address making the experience of searching on the internet better by providing annotated search results, eliminating less useful results, and placing advertisements contextually pertinent to fill out search phrases. At their essence, the inventions seek to reduce user frustration by not linking to web pages that are devoid of all the searched-for search phrases.
For instance, the patents outline systems able to recognize when a search result points to a webpage (or even descendant webpages) lacking one or more of the user's search terms. The search engine would either alert the user with markings or eliminate such results altogether. At the same time, it would make ads more relevant to the entire collection of search terms, resulting in more accurate ad placements and increased monetization.
The Allegations Against Google
Google's lead product—the Google Search Engine—uses these patented technologies without authorization or license, according to the complaint. Google's search algorithm and advertising model necessarily depend on methods that replicate or duplicate the patented inventions, specifically in how search results are ranked, annotated, filtered, and monetized through ad placements, the plaintiff alleges.
AccuSearch claims that the violation is willful and continuous, and demands both damages and injunctive relief to prevent Google from continuing to utilize the alleged technology in the future. Although the complaint has not yet been fully released, preliminary reports indicate that AccuSearch will argue that Google's market leadership in search engines has been unfairly enhanced through the unauthorized utilization of their patented advances.
Who is AccuSearch Technologies LLC?
AccuSearch Technologies seems to be a non-practicing entity (NPE) or patent assertion entity (PAE)—more simply referred to as a "patent troll" in less generous language—intent on profiting from its portfolio of patents more than creating products. It is not unusual for such organizations to buy patents and assert them against large technology corporations as a strategy.
But the sophistication of the patents at issue and their direct applicability to search engine technology may render this suit more than merely another garden-variety infringement action. With a high-profile defendant such as Google and essential search technology at issue, this case may generate significant interest both in the legal and tech communities.
Potential Implications
If AccuSearch succeeds, Google could face far-reaching implications for search engine design and online advertising tactics. A victory in court might result in:
1. Important monetary damages imposed on Google
2. Licensing deals or settlements
3. Modifications to the "look and feel" of search results presented by search engines
annotation of search results
4. Increased scrutiny of comparable patents owned by other organizations
On the contrary, a defeat or dismissal of Google could validate the company's argument that its search technologies are unique or significantly different from the patented process asserted by AccuSearch.
What's Next?
As the case goes on, the court will most probably look into claim constructions, technical similarities, and whether the patents involved are valid and enforceable. It will also have to ascertain if Google's use of the same concepts is literal infringement or infringement under the doctrine of equivalents.
Legal analysts predict that Google could retaliate with motions to dismiss, attacks on the validity of the patents, or even try to transfer the case to a different forum. Meanwhile, the case joins the burgeoning list of patent litigation cases confronting big tech companies, especially in search, machine learning, and user interface.
Conclusion
The result of AccuSearch Technologies LLC v. Google LLC may be used as a reference point for future litigation in search technology. Whether it is concluded in a courtroom war, a silent settlement, or a landmark ruling, it's something worth observing with close interest.
