Lawyers are expensive. If your business model required suing someone to enforce your claim, you better hope you have money, and you better hope you win your case fast. Otherwise, you will spend more time and energy on that lawsuit than your work on invention. It's what economists termed "deadweight loss". It has at time proven to be a business mirage, especially if inventors start suing other inventors and pioneers rather than getting on with copying and improving upon each other's work. Invention and engineering is a collaborative process, even if at time, adversarial. Can't really let a few folks has their monopolies at the expense of everyone else.
