Should Abstract Ideas Be Unpatentable?  The Answer Is A Snap

Tuesday, Kaldren LLC sued Snap.  (According to RPX, Kaldren is affiliated with IP Edge, a notorious patent troll.)  Kaldren sued over a set of expired patents on such wonderful ideas as: Printing out a machine readable symbol; Reading a machine readable symbol; Using an address in a machine readable symbol to retrieve information from that…

ContentGuard: Arguendo

Today, we watched as a man stood in front of a panel and explained how the other side had behaved improperly and how the decisions they made were incorrect and contrary to applicable legal standards. I’m speaking, of course, of the ContentGuard oral arguments.  What did you think I was talking about? Oral Argument at the…

ContentGuard: Validity and Privilege

Monday I summarized the history of the ContentGuard cases, and yesterday I described the process of claim interpretation.  Today, we’ll turn to an issue that we’ve focused on recently, patent validity.  ContentGuard convinced the jury that the ContentGuard patents were valid—can they convince the Federal Circuit?

History Uniloc filed a set of lawsuits against Google based…

Blackbird Gets Wings Clipped In Lighting Litigation

Last week I wrote about Blackbird Technologies, a relatively new patent troll with some ethical and practical issues.  As I found out via Patently-O, it turns out that I’m not the only one who was wondering how they were going to keep confidential information away from their lawyers.  In Blackbird Tech. v.

The Patent Troll’s New Clothes

You might have been reading a bit about Blackbird Technologies lately. Not the Blackbird Raytheon bought in 2014 (cybersecurity) or the Blackbird Etsy bought in 2016 (AI algorithms). (It’s a popular name, apparently.) This one’s a troll. Tailoring a Patent Troll Blackbird was formed in 2014 by attorneys who worked for two major law firms.…
