  • When the firm’s South Carolina-based client was sued in RI as the result of a crane sale transacted over the Internet, a jurisdictional battle ensued.

After initial expedited proceedings, the company withdrew its request for preliminary injunction; the firm’s client counter-sued on several grounds including employment discrimination.

The case finally resolved through a confidential settlement.

  • Defended a Fortune 100 company in a large and multi-faceted patent case in multi-district litigation in the Central District of California.  The case successfully concluded, after the firm obtained a decision on all claims of no literal infringement and invalidated several claims in a combined attack before the Court and the Patent and Trademark Office.

  • When a firm client in the music technology and consumer electric products industry was accused of patent infringement, D&S filed a declaratory judgment suit in Florida.
