If you’re filing patents on minuscule improvements, they’re all going to be typically of fairly low value; and unless you can file very large numbers of those, you’re not going to achieve very much. If you can get into very large numbers of those patents, you can create kind of a thicket that is just difficult to decipher. Not difficult necessarily to get around, but difficult to decipher. So you can get something out of a large number of narrow patents, but typically you have to have a large number of narrow patents to get any value.
