It still happens to an extent, but we’ve gotten far enough to be in a place where basic patents have expired so that most basic companies don’t have to think about this stuff as much.
I do not miss the days of having to work with corporate counsel to try to determine if someone’s “system and method for data retrieval over the internet” patent could be construed to cover our basic REST API and then watching as they evaluated the likelihood of a lawsuit or if it was an empty threat designed to extract a settlement.
