The complete removal of patent infringement liability for the McGrath Series 5 laryngoscope eliminates a key overhang. Traders should monitor for any petition for certiorari, though the nonprecedential nature and strong intrinsic record make Supreme Court review unlikely.

Executive Summary
The Federal Circuit affirmed summary judgment of noninfringement in favor of Teleflex Medical Inc., ending a patent infringement suit over video laryngoscope technology. The court upheld the district court's claim construction of 'mounted on' as 'fastened to the exterior of' and found no genuine issues of material fact regarding literal or equivalent infringement. This removes litigation uncertainty and potential damages exposure for Teleflex's McGrath Series 5 products.
