How Agentic Prior Art Searches Have Changed Patent Practice

It’s no surprise, perhaps, that the advent of AI-driven agentic prior art searches marks a turning point in patent law practice. How, after all, were mere humans going to keep up with the exponential growth of prior art generated by the more than 3.7 million patent applications that are filed globally every year? 

What is less well-known, however, is the extent to which these searches have influenced the entire patent cycle, in turn compounding agentic searches’ effect on the way patent professionals do their work. The impact arises from their ability to significantly change the scope of the information that is available. 

“What stands out about agentic technology is the extent to which it has allowed penetration of a system that has so frequently seemed impenetrable,” says David Hughes, Principal at Griffith Hack, a member of the IPH network.

Penetrating the impenetrable

And just how do agentic searches do that? 

Put simply, agentic searches take prior-art search capabilities well beyond what was feasible with manual processes. 

Among the things that agentic searches can do quickly is generate alternative queries; investigate multiple classification systems; and search non-patent repositories as well as multiple patent databases. Their capabilities also extend to interpreting invention disclosure, evaluating and ranking results, and iteratively defining search strategies. They can produce structured reports that summarize references, map passages to claim limitations, flag novelty-destroying elements, and organize results by relevance – all in next to real-time. 

Instead of spending their time finding and organizing references, patent professionals can concentrate on evaluating and strategizing, turning time spent on mechanical chores into analytical work. 

Client and lawyers benefit alike

“Agentic searches have democratised the patent cycle by creating easier, less costly access to the information that we need,” Hughes says. 

And it is not just the patent attorneys, but the clients, who have noticed. 

“I collaborate with clients who use agentic technology not only for patent searching and screening, but also in developing ideas that may turn into patentable inventions,” Hughes says. 

“Agentic searches have helped clients with the ideation process in general, by collating concepts, and conducting searches based on those refined concepts.” 

Overall, agentic searches reduce the guesswork and time taken in discovering whether an idea is original by quickly showing inventors what’s already been invented, what’s similar, and what’s missing. 

They achieve that because they can: 

  • Extract claim language, compare claim elements, and identify overlapping claims sets; 
  • Group patents by functional similarity; 
  • Detect semantic similarity, thereby revealing narrower claim scope; 
  • Map relationships at a conceptual level; 
  • Identify hard-to-discover “hidden” blocking patents such as continuations and divisionals with later-issued claims, submarine patents, corresponding foreign patents with different claim sets, and patents in related technical fields; 
  • Conduct interdisciplinary searches, potentially sparking creativity; and 
  • Suggest variations, improvements, alternative designs, and ways to avoid conflicts with existing patents. 

The upshot is that clients who use agentic technology come to patent attorneys earlier and better-prepared to discuss patentability issues, providing opportunities to abandon ill-conceived ideas and explore non-obvious variants in a timely way. In other words, clients using agentic searches are likely to have done a great deal of the “grunt” work before seeing counsel, which shifts patent practice into a more front-loaded strategic counselling mode. 

Agentic search systems can also quantify infringement risk by producing and ranking claim-to product, claim-to-claim, and prior art similarities. And the wealth of information that agentic agents can access, whether unearthed by clients or their patent professionals, also means that evidence can become a more influential driver of filing, licensing, and litigation decisions, resulting in greater certainty and fewer prospects for wasted expenses. 

More benefits: drafting and prosecution

Agentic technologies can even incorporate prior art searches directly into drafting and prosecution. 

From a drafting perspective, that’s important because earlier prior art searches can become stale quickly; claim languages can introduce features that are not in the disclosure; prior art relevance can depend on the specific embodiment chosen; adding limitations in claims can create new non-obviousness combinations; and synonyms and equivalents may emerge only after the claim is written. 

The upshot is that real-time searches during drafting are invaluable: after all, the initial searches reveal what prior art says about an invention; but iterative searches conducted contemporaneously with the drafting process answer what the prior art says about the claims. 

From a prosecution perspective, the benefits of agentic systems at their current stage of evolution relates to the analysis of examiner communications. 

In response to Office Actions, agentic systems can create structured representations of examiners’ positions; test examiners’ logic (as opposed to the legal validity of the examiner’s position); generate and test amendments; create argument outlines for responding to examiners; and optimize claims sets. 

Using agentic systems in response to examiner communications, then, allows for more comprehensive analysis of objections, testing of response strategies, narrowing of amendment options, a time-saving draft response outline, and consistency across the prosecution record. That leaves more time to focus on strategy, client communication, commercial considerations, and high-value legal input. 

Finally, agentic systems can extract patterns from repeatedly observing inputs and outputs about technologies, drafting patterns and prosecution strategies, and carry the patterns forward. They can build context which can be technology or client specific. 

Humans still matter

Agentic searches have not merely changed the tools patent professionals use, but also changed the very nature of their work. In the process, however, human involvement has not lost its relevance. Indeed, there’s a strong argument that the emergence of agentic searches has expanded, rather than diminished, the role of patent professionals by freeing them to operate at a higher level. 

The domain knowledge of patent attorneys and other patent professionals becomes central to validating the outputs of agentic AI, which is essential if they are to be relied upon for business decisions or legal process.  System choice and deployment is critical to manage risk and to achieve the best outcomes with specialist IP-specific tools allowing greater insight than more generic AI systems. Therefore, there is still significant advantage from working with a professional who uses those tools daily and can incorporate their experience to the nuances of a specific challenge. 

“It is true that no conscientious patent professional can be oblivious to or ignore the emergence of agentic prior art searches, but human responsibility, accountability and the exercise of professional judgment will always be issues,” Hughes says. “From an input perspective, those issues embrace documenting inventor involvements, selecting and deploying the proper tools from the host of choices out there, merging AI tools that have different capabilities, and integrating all this into overall work practices. From an output perspective, it is about supervising and verifying generated content, maintaining quality standards and managing rights.”
