A greedy patent troll that has already bagged Apple (s aapl), Cisco and many other Silicon Valley firms is heading back to Texas to demand Facebook (s fb) and others pay up for including a spam filter in their email systems.
The company first made headlines in 2010 when it sued 36 companies over US Patent 6018761, claiming that “E-mail as we know it would essentially stop working if it weren’t for [the] invention.” Like others of its ilk, the firm has a name — “InNova” — that conveys technology even though it is just a shell company that does nothing but file lawsuits.
The patent itself was issued in 2000, four years before Facebook launched, and covers a “System for Adding to Electronic Mail Messages Information Obtained from Sources External to the Electronic Mail Transport Process.” The new lawsuit accuses the social network of:
using … electronic-message filtering products and/or services that embody the inventions claimed in the ’761 patent, including but not limited to Facebook Email and all reasonably similar products.
Court records show that most of InNova’s 2010 victims, including Apple, Yahoo (s yhoo) and HP have thrown in the towel and settled, while Google (s goog) and AOL (s aol) continue to dig in. Now, in addition to Facebook, the companies new roster of targets includes Microsoft (S MSFT), Lycos, eBay (S EBAY) and Comcast (S CMCSK).
Palo Alto lawyer Christopher Banys is leading the new cases and, as before, the litigation is taking place in Marshall, Texas which has a reputation for plaintiff-friendly juries who enjoy sticking it to technology companies. Banys will be working with Texas firm Ward & Smith which recently hired T. John Ward, a former federal judge who established East Texas as a leading patent venue. The firm was founded by Ward’s son, noted patent troll lawyer T. John “Johnny” Ward Jr.
The new lawsuits comes at a time of growing frustration with the patent system. A famous judge who is presiding over a dispute between Apple and Google recently called the patent system “dysfunctional” while thought leaders in Silicon Valley are calling to end software patents altogether.
