It's interesting to note Lexmark tried to (ab)use other kinds of so-called "intelectual property" laws earlier: the copyright law and DMCA. When they failed, they decided to use patents instead. And all this for what purpose? To prevent people from using cartridges manufactured by other companies, i.e. blocking competition and acting against free market and user rights. If this isn't abuse, I don't know what it is. If you can't build a superior product supported by good marketing, don't try to save yourself by legal action. If you do, you only alienate your customers, the very people you should serve first.
