Title: PPA - How much detail is too much?
Post by: DeepOrange on April 21, 2019, 07:16:20 AM
Hi.

I am drafting a PPA for a kitchen apparatus. I have gone into great detail (approx 4000 words and 14 drawings) describing the various preferred components and methods of operation, both in general and specific terms.

I have built a crude proof of concept prototype, but the PPA describes a much more detailed embodiment, that is yet to be proven physically.
The mechanisms are fairly simple, but the description describes them in detail even though (in my opinion) the functions are quite obvious.

My question is can you go into too much detail? Or is it better to leave a PPA more general and add the specific detail later when converting to a full patent?

Usually having too much details is better than leaving something out so it sounds like you are doing everything properly.

Thanks Brad. That is comforting!

On the same track, would putting numerous claims into a PPA be appropriate as well?
I understand that many claims will be rejected when converting to a full patent, and quite likely that the embodiment of the invention will change.

Is therefore unnecessary to be fixated on claims at all?

I usually tell people not to spend a lot of time on the claims and usually most non-patent people don't write the claims properly to begin with.  However, writing the claims in a PPA serves a valuable purpose though because it forces you to focus and cover the key aspects of your invention.   So I would suggest writing these out in at least bullet point format and you can include them in the Brief Summary of the Invention section but don't really need to file them as "claims" in the PPA or spend time trying to word them in "legal speak" to make them look like proper claims.
