Patent number: 9935936Abstract: A federated realm discovery system within a federation determines a “home” realm associated with a portion of the user's credentials before the user's secret information (such as a password) is passed to a non-home realm. A login user interface accepts a user identifier and, based on the user identifier, can use various methods to identify an account authority service within the federation that can authenticate the user. In one method, a realm list of the user device can be used to direct the login to the appropriate home realm of the user. In another method, an account authority service in a non-home realm can look up the user's home realm and provide realm information directing the user device to login at the home realm.Type: GrantFiled: June 27, 2017Date of Patent: April 3, 2018Assignee: Microsoft Technology Licensing, LLCInventors: Wei-Qiang Guo, Lynn Ayres, Rui Chen, Sarah Faulkner, Yordan Rouskov

Patent number: 9675681Abstract: A shortened process for producing a solution containing substantially purified capsular polysaccharides from a cellular Streptococcus pneumoniae lysate broth is described. Ultrafiltering and diafiltering a clarified S. pneumoniae lysate followed by pH adjustment to less than 4.5, preferably about 3.5, precipitated at least 98% of the protein in the solution without seriously affecting polysaccharide yield. Furthermore, following ultrafiltration and diafiltration and acidification to a pH of less than 4.5, filtration using activated carbon precipitated at least 90% of remaining protein without seriously affecting polysaccharide yield. Exemplary, non-limiting S. pneumoniae serotypes that can be purified using the shortened process of the invention are 1, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F.Type: GrantFiled: February 27, 2015Date of Patent: June 13, 2017Assignee: Wyeth LLCInventors: Yonghui Yuan, Mark Ruppen, Wei-Qiang Sun, Ling Chu, John Simpson, James Patch, Justin Keith Moran, Pamela S.
