UMBRA Technologies (US) Inc., UMBRA Technologies Ltd., and UMBRA Technologies Limited (CN) have filed a District of Delaware complaint against Juniper Networks (1:24-cv-01288). The coplaintiffs target the provision of network virtualization products and services with three patents, one familiar to this campaign and two making their litigation debut. The familiar patent has survived reexamination, with the patentability of all claims confirmed, and has (thus far) survived inter partes review (IPR), the Patent Trial and Appeal Board (PTAB) having declined to institute trial in response to a prior defendant’s petition.

Three “individual private companies in association with each other doing business collectively as Umbra Technologies” have together filed separate Western District of Texas suits against Cisco (1:23-cv-00903) and VMWare (1:23-cv-00904). The defendants are accused of infringing four network security patents through the provision of their respective network virtualization products and services. The complaints define “UMBRA” to be the three plaintiffs collectively, with the coplaintiffs later pleading that “UMBRA” is “the assignee and owner of the right, title and interest in and to” each patent-in-suit.
