OpenAI’s latest chatbot, ChatGPT, undoubtedly produces some seriously impressive results. Indeed, it’s often difficult to tell, at first glance, that the text was generated using a chatbot. However, the internet (and particularly my LinkedIn feed) has been awash over the last week with examples of situations where, whilst ChatGPT’s output is fluent and coherent, it’s also just plain wrong. Many politicians make careers out of hiding an inaccuracy due to how coherently they convey the inaccuracy.

Relatedly, it is common for inventors to try to reduce the costs of writing a patent application by wanting to help do part of the work. Often, efficiencies can be realized where the inventor produces some parts of the application and drawings themselves, and/or where an invention disclosure form is used.

As any patent attorney will know, there is rarely anything less likely to save money than an inventor who has written their own claims and wants their patent attorney to “just quickly review and file them”. Whilst I applaud the intention of such inventors, I also know that I have rarely been able to “just quickly review and file” such inventor-written claims.

It does not seem to be such a great leap to imagine an inventor asking ChatGPT to draft a patent application for their invention (or even just a claim set), and promptly handing that to their patent attorney as a useful starting point, or just to check and file. I am generally against this being in most inventor’s best interests for several reasons:

  1. Cost: The results from ChatGPT are not perfect. For claim drafting, I expect it will take longer to start from ChatGPT-generated claim wording and try to understand the true invention, than to start with a conversation with/disclosure from the inventor. It sometimes takes longer to check something is correct than to just write it correctly the first time. There may well come a time where ChatGPT-like solutions can genuinely write robust, accurate, insightful claims, but now is not it.
  2. Quality: One mark of a good patent attorney might be one who doesn’t want to start drafting a patent application until they understand how the intellectual property will be used. It may be that the most valuable protection is to be found in a claim directed to a different aspect of the product or process. Re-directing a drafted claim set, may be more difficult than starting to write the claims only when you know the direction in which to proceed.
  3. Confidentiality: Depending on user agreements, it may be the case that disclosing your invention to systems like ChatGPT would invalidate any subsequently-filed patent applications because the idea would have been provided to ChatGPT with no obligation to keep it confidential.
  4. AI Inventorship Issues: If the general idea was your own, but ChatGPT suggested particular fallback positions that ultimately make it into the granted claims, are you still the inventor? Is there even an inventor at all? Case law (and statutory law) is currently developing in this area and is likely to develop further in the future. I would prefer to not leave open the question of whether an AI engine contributed to inventorship.

Despite all of this, I remain convinced that AI engines such as ChatGPT will have huge positive impacts on many aspects of my work over the next few years, improving the efficiency and effectiveness of my practice and advice. It is an exciting time.

Finally, this would not be an article about ChatGPT without a quote. Here is the result of my request for an introduction to an article about the risks of inventors using ChatGPT to write a first draft of their patent claims:

Chris Cottingham“The use of artificial intelligence has become increasingly common in a variety of fields, including the world of patents. Some inventors may be tempted to use large language models, such as ChatGPT, to write the first draft of their patent claims in an effort to save money on attorney fees. However, this approach may actually end up costing inventors more in the long run. In this article, we will explore the reasons why 

using ChatGPT to write patent claims is a risky and potentially costly decision. We will also offer some advice on how inventors can effectively collaborate with their attorneys to create strong and defensible patent claims.”

So, am I out of a job? Not yet, but I may need to work harder to convince clients of that answer.
