I am trying to submit my first provisional patent in the UK but I keep getting confused about what sort of information I should put in at this stage. I know I should put as much information as I can, but I'm not sure how much is enough for now. Lets say I have made an iPhone app that communicates with the fridge. Obviously there should be a hardware in the fridge that connects to the fridge and theres some software that tells the hardware how to act. For example, lets say the iPhone app is able to turn the fridge's lamp on and off.
In this case do, I have to submit 2 provisional patents? One for the iPhone app and one for the fridge's hardware?
To what extent should I draw the hardware in the fridge? (Btw I am not making anything even close to fridges)
I thought that a provisional patent will allow me to disclose my idea to my potential customers and to get feedback from them. What if I receive feedback and I want to improve my hardware or software again? What happens to the provisional patent?
Basically, I have an idea that seems patentable. The idea itself requires a hardware with a custom made software on it and an iPhone app. I still don't have a final design for my hardware but the hardware itself is functional and I managed to take a video of myself showing how the hardware works. My plan is to 1. patent my idea. 2. disclose my products to my potential customers, show them the video of how the device works, and improve my product if there's something missing. 3. After I receive interest from my customers, I ask them for a letter of intent so that I know what to expect for year one. 4. look for investors to raise funding in order to hire more help to complete the final stage of the product and to manufacture the hardware.
I've seen some websites that say that I should even include all my code in the provisional patent as well as all the drawings, algorithms, drawings and... What if I want to update the code after I submitted my provisional? I've also seen some other websites that say a provisional can be submitted in 20 min just by just explaining the idea and the general concept of it and the designs can don't have to be that serious. They even say that there is no need for a lawyer for a provisional. I really don't know which one to believe and I don't want to make a fool out of myself when a customer sees my provisional patent. Does anyone have any similar experience in the field of IoT? Am I missing something here?
Thanks in advance!
