Microsoft’s options are dwindling in a patent-infringement case brought by i4i, a small Toronto firm that sued the software giant for infringing on its patent for a custom XML editor.

Now, the U.S. Patent and Trademark Office has issued a “Reexamination Certificate” validating i4i’s patent.

Datamation takes a look.
