Characterizing itself as an “ISO 9001:2015 certified firm that is committed to providing the highest quality of IT sales and services”, Sterling Computers Corporation has sued Microsoft (1:24-cv-00406) over the provision of its Exchange Online platform, targeting features related to “mail flow rules”. In the new Western District of Texas complaint, the plaintiff asserts a single patent generally related to an electronic messaging system with a “governance module”, the pleading characterizing the patent as covering an “object-based messaging invention” that allows each message in an email thread to be stored only once.
