@jokoon The low quality patents are typically not found to be valid in court. The problem is, a founder does not want to spend the money and (most importantly) time to go to court. He/she wants to work on the startup. Also, some patents are strong, and some are of low quality. The low quality patents exist, in part, because the patent office does not have the resources (i.e., enough personnel, training and search technology) to perform a proper analysis. Those resources are lacking because congress takes funds from the patent office (the patent office could be otherwise self funded if not for congress taking the funds to use for their pet projects).
