I think my colleagues will want to jump in on this one too, if that's okay.
I could perhaps get started by offering that patent thickets, as a phenomenon, aren't novel to the current day and age. They are emerging as an issue in some sectors, and we're hearing from businesses that they are an issue. It has been noted that patent thickets arise when there is an upsurge in innovation in a particular area.
We understand the first patent thicket, in fact, revolved around the sewing machine, and the solution in that case revolved around bundling things together so as to rationalize and condense it. But the fact is, when there are a lot of inventions happening, and multiple inventions go into a single product like a cell phone, this is a phenomenon that we tend to see.
