There are exceptions to ever rule, but generally patents are (1) not incredibly important in software (2) solving a question that's secondary.

The biggest risk to building a startup isn't "can I build this thing" (feasibility risk). It's "will people even care if I build this thing" (value risk) then "can I do it in a way people use" (usability risk). Patents help solve business risk, but that's generally considered to be the 4th (and last) of the risks.

There are exceptions where patents do need to be filed first or the business viability dies. However, I generally assume that if you've addressed value, usability, and feasibility risks to create something truly meaningful, your competitors will find a work around to deliver the same value, usability, and feasibility without infringing on your patent. Thus, patents, are nothing but a minor inconvenience. In some cases, the public filing of a patent, can give your competitors a leg up on competing with you.

From what I have seen, early investors care far more about speed, adoption, and clarity of problem than provisionals. Patents help later, but at pre-seed/seed they rarely change a decision unless IP is the product. Shipping and learning usually wins.

Typically not much, but in practice if you truly have a unique technical moat it's easy enough that I'd get a provisional patent in place just in case.

I would start accumulating patents at a gradual pace at around $100m ARR in preparation for IPO, assuming that you feel that is in the cards.

Could make sense to file provisional patents, just to be able to say you have them. Expect no one will actually look at them. And remember that if you don't file a follow up within a certain time, they die.

What are you delivering? A physical product into someone's hands? If so, a patent can make some sense. If not, don't bother - patents for software are rarely worth the paper they're printed on.

I work in IP. You can easily operate without patents. Patents cost money to file and maintain. Most patents exist only for marketing purposes. Enforcement also isn't cheap. So, unless the IP is perceived to be highly valuable, corporations don't bother filing the patent. Only a fraction of what's patentable ever gets patented.

You might consider a non-disclosure agreement with parties that you need to share things with.
