Linux Weekly News reports that:
Personalweb Technologies and Level 3 Communications have filed a lawsuit [PDF] against Rackspace, alleging that Rackspace’s hosting of GitHub infringes upon a long list of software patents.
One of the comments lists a few possibly related law suits:
PersonalWeb Technologies LLC et. al. v. Yahoo! Inc. filed yesterday in Texas Eastern Civil Action No. 6:12-cv-00658
PersonalWeb Technologies LLC et. al. v. Apple Inc. filed yesterday in Texas Eastern Civil Action No. 6:12-cv-00660
PersonalWeb Technologies LLC et. al. v. International Business Machines Corporation filed yesterday in Texas Eastern Civil Action No. 6:12-cv-00661
PersonalWeb Technologies LLC et. al. v. Facebook Inc. filed yesterday in Texas Eastern Civil Action No. 6:12-cv-00662
PersonalWeb Technologies LLC et. al. v. Microsoft Corporation filed yesterday in Texas Eastern Civil Action No. 6:12-cv-00663
Given the description of the company:
PersonalWeb is a proud member of the East Texas community. We are now 14 employees strong and growing. We own 15 key pending and issued patents that are critical to the development of a wide range of established and emerging distributed computing based industries and fundamental for cloud computing, distributed search engine file systems, content addressable storage and social networks.
That leaves a horribly familiar SCO aftertaste.
