Significant number of Rockstar patents to expire in 2017

The report states that beginning in 2017, "there will be a significant increase in [patent] expirations."
August 3, 2014

As this site has discussed on a number of occasions, patent trolls continue to be a burdensome, innovation-less group on those trying to actually innovate in today’s world.

Recently, we wrote about Rockstar, a shell company that was set up by Apple, Microsoft, Ericsson, Sony, EMC, Blackberry and what’s left of Nortel Networks and their 6,000 patents. Rockstar is a well-known troll that is actively targeting hundreds of Silicon Valley companies.

Recently, Rockstar decided that they would start suing others that used any sort of calendar alert. Specifically, the patent was titled “System and method for notifying a user of an incoming communication event.”

When Rockstar is not suing Google and all Android manufacturers, they are busy filing lawsuits against Charter Communications, Cable One, the Arris Group, Cisco Systems and others.

Now, a legal technology consulting firm, Elysium Digital, analyzed Rockstar’s patent portfolio as of February 21, 2014.

“The firm’s report focuses on the U.S. patents and applications, and includes analysis of current assignments of patent and application assets, areas of technology covered, and timing of patent expiration dates. Elysium based its analysis on public data, including file histories, reassignment data, and patent text provided by the U.S. Patent and Trademark Office.” – FierceWireless

The report states that beginning in 2017, “there will be a significant increase in [patent] expirations.” The report also states that between 2019-2021, there will be more than 400 patents expiring in EACH of those calendar years.

As FierceWireless notes, Rockstar’s patents involve “30 percent of patents related to switching and routing; 19 percent relate to telecommunication network techniques and systems; 11 percent relate to optical communications; and 6 percent relate to cellular and mobile communications.”
