The district court's finding that the claims were mutually exclusive 'forced itself into a later conclusion of indefiniteness, which it did not have to do,' the CAFC added.
In a precedential decision, the CAFC vacated and remanded a district court decision that invalidated all claims of Vascular Solutions and Teleflex LLC's patent infringement suit against Medtronic, Inc.
The CAFC said the district court erred when it found the asserted claims were 'mutually exclusive' and indefinite and that claiming is not restricted in the way the district court concluded.
Teleflex sued Medtronic for infringement of 40 claims across seven patents directed to a coaxial guide catheter that is deliverable through standard guide catheters by utilizing a guidewire rail segment.
