Not on anything like the same scale.
I only rarely mention this on HN because it's like being a particularly obnoxious lightning rod in the tropics, but I have a patent pending at the moment. It's been a slow and expensive process.
So far I am about AUD $17k into the process. This has netted me a WIPO PCT filing, which I have now parlayed into an Australian filing and soon a USPTO filing.
What nobody tells you at the beginning is that it all takes much longer than you think it will. And costs a lot more, because you have to file in each country independently. If I am granted a US patent, that's the lynchpin, the key element that would make a portfolio of patents worth a damn. But then I will still need to stump thousands more dollars per country to file elsewhere.
A company like Apple doesn't have the problem of fretting over the cashflow implications. They are not carefully shepherding a single filing that cost-wise represents a meaningful fraction of their revenue and assets.
Instead, to many companies, patents are a pipeline. A factory. They have on-staff lawyers to pump a constant stream of applications into global offices. They have economies of scale and generous cashflows that I simply don't.
Because of the economics of the situation, patents favour wealthy incumbents, not upstart inventors. There's been a priority inversion.
