""That guy at Fish," of course, is Scott Harris, the prominent San Diego patent attorney who was ousted from Fish & Richardson one year ago, after his patent was asserted in a lawsuit against firm client Google Inc. But Harris is not alone. Other lawyers are also inventors who, having seen the fortunes earned by small patent-holding companies, have decided to play the patent litigation game as a principal, not just an adviser. At least 10 law firm lawyers have filed lawsuits to protect their own "inventions" in the past few years, even as critics denounce active patent enforcers as "patent trolls." The plaintiffs' claims are broad, and several have sued entire industries; some have done so as they continue to work at top-name law firms."
