I don't believe private entities wouldn't invest in research if it wasn't for patents. But I also don't care. If the private sector won't invest, let the public sector invest. Just don't keep innovations out of the hands of humanity.

So yes, in a world with patents, private entities would still engage in research, but what would they gain from disclosing the details of their process?
1. Successfully provide a profit
2. Are necessary to provide said profit
3. Are long enough to provide enough profit to pay back the investment
But it's not clear that they're short enough to encourage further rapid improvements. Like, suppose a patent lasts 20 years but would still be worth pursuing even if it lasted only 5 years; that's 15 years of public development opportunity lost, for each patent.
Currently, the system is that the government declares "X years" by fiat. If it's too short, then corporations can lobby for longer patent durations. If it's not too short, then corporations can lobby anyway. This is a functional but mediocre system, and there's clearly room for improvement.
They might not gain, but the people working for them would certainly gain from moving to other employers who needed their "expertise".
