Following lawsuits against Groupon, digital marketing firm Blue Calypso is now targeting rival LivingSocial with its latest patent lawsuit. According to the company, US Patent Nos. 7,664,516 and 8,155,679 are specifically being violated, which are supposedly used in Blue Calypso’s “state-of-the-art digital marketing platform.”

Diving deeper, the 7,664,516 patent was filed all the way back in 2005 and references “a method and system for peer-to-peer advertising between mobile communication devices.” The second patent, filed in 2009, follows the first, and as you’d expect, both are highly vague. Nevertheless, these are the same patents being used against Groupon as of August 1st.

According to Bill Ogle, CEO of Blue Calypso:

As a technology innovator, it is our duty to protect what we have created from illegitimate use. The current landscape for social engagement is growing and with that brings interest and need for the platform we developed and operate. It is our plan to monitor for infringing companies and ensure that our assets are protected now and into the future.

At the moment, we haven’t seen any progress made in the first lawsuit against Groupon, but those results will likely set a nice precedent for the LivingSocial suit. We have reached out to LivingSocial for a comment.
