Recently I heard that TQP (a company) is suing several companies, some of them being Apple, Google, Intel, Dell, etc., for using SSL/TLS on their websites.
This company, apparently have a patent on the algorithms used in very generic terms, meaning they can use this to their advantage and sue companies using SSL/TLS and similar algorithms if they exist or will exist at some point.
To be honest, I think this is bs, waste of time, resources, money, and that these lawsuits are simply made to make money, nothing else. It's not really protecting their IP (Intellectual Property), as they didn't invent SSL or TLS, or RC4 for that sake. They are non-technical persons just wanting to make a lot of money by suing people like the world's "No. 1 Hacker", except he just does it with people and companies he doesn't like.
