The Verdict & Legal Analysis
Outcome
The case was resolved by **voluntary dismissal** on May 13, 2013, just 61 days after its filing. This means no judicial ruling on infringement, validity, or damages was issued, and the specific financial terms, if any settlement was reached, were not publicly disclosed. No injunctive relief was granted or denied by the court.
Key Legal Issues
The swift resolution, ending in voluntary dismissal under Federal Rule of Civil Procedure 41(a), suggests that the parties reached a negotiated settlement or licensing agreement, or Medtronic strategically withdrew before any substantive rulings. This case illustrates the utility of voluntary dismissal as a litigation tool – allowing patent asserters to test adversarial resolve, open settlement channels, and exit gracefully if early case assessment shifts, while avoiding adverse rulings that could undermine the patent’s broader portfolio value.
