So if we take any given year, say 2014, and we file 100 patents in that year, and at the time we file those 100 patents we’re kind of thinking, “Well, some are more valuable, some are less valuable, but they all have some value.” Well, if we were to fast forward five years, most of those patents – and when I mean most of them it varies, but typically somewhere around 80 percent of those patents that your – applications you filed and ultimately perhaps patents in 2014 – now we’re in 2019 or ’20, say – most of those are no longer valuable for the reasons given before. And so you’re gonna have a handful, typically, of valuable patents. Maybe you’ll have 20 out of 100 that you think are valuable, and out of that 20 there may only be 2 or 3 or 4 or maybe 5 that have a lot of value.
