USPTO records indicate that late last month, K.Mizra LLC acquired over 100 US patent assets—plus foreign counterparts—from Rambus Inc. The assignment was executed just as a campaign involving former Rambus patents, this one waged by a different NPE, came to an apparent close.

Last week, RPX reported that Rampart Asset Management LLC—formed in Texas by Peter J. Hardigan—had expanded its memory controller campaign with a case against TI, preceded by 2021 suits against each of NXP Semiconductors and Renesas Electronics. The asserted patents are a small subset of the more than 80 US patents assets that Rambus Inc. assigned to another entity, apparently also under Hardigan’s control, in August of last year.
