Microsoft’s Renewed Challenge to i4i Patent is among Reexamination Requests Filed the Week of August 30th

Here is the latest  installment of Reexamination Requests from Scott M. Daniels, of Reeaxamination Alert and Practice Center Contributor which includes the requests for the week of August 30th…
