This week I wrote and filed a complete patent application for a side project of mine all by my own for the first time. I've done some patents in the past but those were through my employers and using patent attorneys to do the drafting.
For most of the technical text drafting ChatGPT proved to be overchallenged, however it was a phenomenal help answering dozens of questions that I had about specific wordings, goals, processes, things to avoid and more. The type of information I would have searched on Google for hours with uncertain chances of success. Sure, there's a chance that ChatGPT just made it up but most of the answers made complete sense in my view.
I also used it to rephrase some boilerplate from other patents that needed to go in there but which I didn't want to copy verbatim. It did well in most cases but failed in about one or two.
But overall still blown away by it and pretty sure we'll see rapid progress from here.
