Rimini Street, a third-party software support vendor for SAP and Oracle applications, sees a long court battle in its future. And it’s preparing for it.

The company announced yesterday that it has hired top legal gun Daniel Winslow to head up its law department as it heads into a courtroom showdown with Oracle. Oracle filed suit against Ramini for patent infringement. Rimini countersued, claiming it works within the legal parameters of its software license agreement. A trial date, while not yet set, is imminent.

Winslow, who has 30 years of trial experience under his belt, was a member of the Massachusetts House of Representatives and chief counsel to Republican Presidential candidate Mitt Romney. He is Rimini’s first-ever general counsel.

“Rimini Street is a great story of innovation and a fast-growing disruptive service offering that meets the needs of Global, Fortune 500, public sector and mid-size businesses around the world. The more I learned about the company and its exciting global growth, the more I wanted to be a part of it,” Winslow said in a statement. “Rimini Street is approaching a decade of industry-defining leadership in enterprise software support, and I look forward to working with my new colleagues on the senior management team to execute Rimini Street’s aggressive global business plan.”

Winslow’s courtroom experience includes patent, trademark and copyright litigation, regulatory compliance, telecom and Internet and entertainment law. As chief counsel for Romney, he managed more than 800 in-house and outside counsel.

“Dan brings with him an impressive history of leadership, achievement and wide-ranging experience throughout his 30-year legal career,” Seth Ravin, Rimini Street’s CEO, said in a statement. “We are pleased to have Dan join us and look forward to adding his capabilities to the executive team as we embark on our next phase of accelerated global growth and expansion.”
