We represented AutoZone in a patent infringement case and were granted summary judgment of non-infringement. EMG Technology filed suit claiming that AutoZone’s website infringed upon the company’s patented system for creating sister websites, specifically referring to AutoZone’s reformatting of its main site to a mobile version. U.S. District Judge Michael H. Schneider of the U.S. District Court in the Eastern District of Texas granted summary judgment of non-infringement, finding no issue of material fact that AutoZone’s websites did not infringe the patent because the company’s main site is in XHTML and its mobile site uses the HTML-serialization of HTML5, whereas the patent requires conversion from HTML to XML to create a sister site. The court thus found that AutoZone did not infringe the patent literally or under the doctrine of equivalents.
