PPA Application

PPA Application
« on: June 01, 2022, 07:51:24 AM »

I'm a bit confused as to the need for a PPA (Provisional patent application)
I know the purpose of it and the basic need for it but the practicality doesn't make any sense.

I'll explain why.
Lets say I file for PPA in USA and receive filling number. Once I receive it I am able to launch my product commercially if
I wanted to and be able to place the words "patent pending" on the product for the next 12 months until I'm able to do a full patent application. Lets put aside the fact that it would destroy the novelty by making it publicly known. I should then be able to sell my product until someone who owns the original invention tries to stop me from selling it due to them having a patent registered in the country that I'm selling my product in. Seeing that no patent search is conducted by examiner on a PPA their might be a possibility that the invention already exist or something very similar which means I would have enjoyed 12 months of selling my product without any legal issues. If the person of the original invention or something similar has registered their invention in a different country as to the one I'm selling in then I am to understand that they will have no legal cause to stop me.

Lets say that if someone else comes up with the same idea or something similar within my 12months timeframe and they have also made their product publicly known and starts selling it, who would have the rights to claim when they file the full patent. I would assume the person that filed their PPA first. This would also mean that both of us would have had almost 12 months of selling our products on the market and the person that is awarded the rights to the full patent can them legally force the other person to remove their product from the market depending on which country it's sold in and where they have filed the full patent. Now from my understanding it there will be a race as to who files for the full patent application first.

I basically want to file my PPA and start selling my product immediately in various countries with the word "patent pending" but I don't want to infringe on any other persons patent rights or have someone else seeing my product and files for a PPA or even a full patent. I am aware that once a product is publicly known then no person can patent it accept the inventor themselves but how does the patent office know if the product is on the market seeing that the inventor only filed a PPA and it's not examined. I assume when the person wants to do a full patent application then the examiner will be conduct a proper search in the market and on the patent database but what about a PPA or if the patent is rejected the applicant can then just register it in a different country where it's not registered or even sold.

I don't understand this. Can anyone shed some light on this.

Hi Louis,

I think there are few big misunderstandings on your part.  I am not trying to "upsell" you here but I think a $150 consultation with me or another qualified person would be beneficial to help walk you through different strategies and ideas based on your goals.  It is a complex process with many potential pathways.     

The biggest thing is that a patent application or even a fully issued patent does not give you permission to sell anything.  It is a defensive tool used to stop others.  That is a huge difference that most people don't realize.   Just because you file your patent first does not mean you have some clearance to launch a product.   See this post here:  and this one

The main reason you would file your PPA is to lock on your priority date.  You full (non-provisional) can then link back to your provisional.  Because the upfront cost of the PPA is so much less, if done properly, a PPA can be extremely powerful for relatively little cost.    In one example, lets say you file a good PPA for $2,000.   Ten months later your competition files a full non-provisional using an expensive Boston law firm for $15,000.   You later file your non-provisional and link it back to your provisional.   Because your applications have an earlier priority date (based on your PPA date), you can block the other company from getting their patent approved because you have the earlier date.
