Patent Claims Drafting: Human vs. AI

Mahish K. Guru

“AI will never draft a patent document, particularly Claims that prevent potential infringement.”

“AI can't generate creative strategies covering all angles, nor adopt an infringer's perspective while drafting Claims.”

“AI excels in research but won't replace patent agents and attorneys.”

These arguments often discourage leveraging AI in IP documentation.

I agree that AI is far from replacing patent agents or attorneys, not because it can't, but due to the crucial trust and responsibility between inventors and human agents. This trust, essential for understanding the client's business, is beyond AI's capacity and likely will remain so.

How can GenAI be creative enough to preempt potential infringement?

The same way humans do: using context and experience.

Humans achieve this through contextual comprehension of the invention and its domains. Patent agents, through extensive experience in drafting workflows, understand which areas need protection in claims.

Engineering AI to emulate this requires imbuing it with sufficient context about the invention and related innovations, and providing historical data on the drafting process to replicate such strategies.

Creativity often combines previously unconnected abstract concepts. Thus, the question isn't whether AI will match a patent agent's creativity and experience, but how we can leverage its current capabilities for augmenting human expertise.

Advantages and disadvantages of having AI generated Claims.

In this section, we compare two sets of draft claims for an invention titled "A MODULAR SUSPENSION FRAME FOR A VEHICLE". One set of claims is from the actual documentation of the already granted claims, drafted by humans. The other set is an initial draft of claims generated using AI, given the same context of the invention disclosure available to humans for drafting the claims.

For the reference of the reader, given below are two figures of the invention out of the 6 given to both human and AI.

Conclusion

Human claims tend to be more exhaustive and explanatory than AI claims in some areas, while also being very specific in others. They handle the balance between breadth and narrowness more effectively than AI claims. For instance, specifying 'light commercial vehicle' instead of just 'vehicle' showcases human claims' ability to set the scope of a claim based on context.

AI follows textbook guidelines coherently, such as using consistent terminology in drafting claims, use of antecedant basis and avoiding the use of indefinite terms. However, these attributes are sometimes missed in human claims.

AI claims are consistently specific, leaving no room for ambiguity. This is a positive aspect, but it also restricts the breadth of AI claims.

AI often lacks an understanding of what details should be included in dependent claims to support the independent claims or to explain the functionality or further scope of the components claimed in the independent claim.

Human claims are not only more exhaustive and explanatory than AI claims in some areas, but they also break down the invention into multiple embodiments. This makes safeguarding the invention more strategic, as it opens the scope of infringement to future inventions. The mention of 'light commercial vehicle' instead of just 'vehicle' in human claims further demonstrates that AI does not inherently understand how broad to make the claims, and instead picks up hints from the context of the IDF given for how broad the claims need to be.

Responsible use of AI for Claims Drafting

Rating the claims made by AI in comparison to those drafted by humans for this well-written patent draft is very subjective. It largely depends on the drafting style of the patent agent or attorney, as they will have their own preferences. Personally, I believe the AI-generated claims are already at 70-80 percent of the level of the human-generated claims in this case.

While the claims generated by our model at PatentAssist.ai are not final and cannot be directly submitted to the filing office without review, it's important to remember that they were generated with no manual effort and in under five minutes. A patent agent who has access to these AI-generated claims already has a blueprint to work upon and only needs to edit, modify, and improve the claims for a more exhaustive approach or to generalize them and make them broader.

The speed to reach the optimal stage of patent drafting, which maximizes the safeguarding of the invention, is much quicker using AI. It also results in well-structured and formal legal language. Tools like PatentAssist.ai make this process faster for claim drafting.
