Seriously? Even the US patent office would balk at an application to patent 90-day trials or 90-day certificates. Also, Let's Encrypt isn't doing trials, so patenting the first wouldn't even make sense.

Even if it doesn't... wouldn't Let's Encrypt just be able to change the default to 60 or something like that?

Yeah, but if it was a defensible patent they would still be on the hook for using it at all. Thankfully, Let's Encrypt could show literally hundreds of cases of prior art for X-day trials.
