Juniper Networks is the latest defendant to be added to the long-running, wide-ranging litigation campaign of Marshall Feature Recognition, LLC (MFR). As it has throughout the dozen cases that it has filed this year, MFR asserted two related patents (6,886,750; 8,910,876) from a family of over 35 against Juniper. The patents generally relate to printed materials with machine readable features that can be used to access related digital information. The campaign targets defendants’ use of QR (quick recognizable) codes in printed advertisements.
