Doug Ringel from Kenyon & Kenyon Joins National Firm Kacvinsky, Daisak & Bluni, Bringing Significant Experience in Litigation; Arrival Marks Firm’s Third Principal Hire Since October

WASHINGTON, D.C., December 9, 2015 – Kacvinsky Daisak Bluni PLLC today announced the arrival of Douglas E. Ringel as a principal to the Washington, D.C. office of the national 29-lawyer intellectual property law boutique.

Joining from Kenyon & Kenyon, Ringel brings more than 20 years of experience in all aspects of IP. He has substantial experience in high-profile patent and other IP litigation as well as in obtaining patents, providing strategic counsel and opinions regarding IP rights, conducting due diligence, and handling licensing and other transactions across a wide range of industries, from medical devices to computer technology and electronics.

“Doug is an ideal fit for KDB,” said Scott Bluni, a firm principal and managing partner. “As a senior lawyer, he has built a solid practice and knows the intricacies of IP law from various perspectives and across several industries.”

Ringel is the third principal to join KDB since October when the firm announced the arrivals of Kurt Lockwood from Boston Scientific and Karen Feisthamel from CVS Health, added Bluni. “Doug joining KDB underscores our commitment to building a firm with senior IP lawyers with relevant hands-on knowledge. His experience in patent and litigation matters bolsters the value proposition that we offer our clients.”

For Ringel, the attraction to KDB is its high-caliber lawyers, compelling legal work, cost-effective infrastructure as well as an opportunity to help build the firm’s litigation practice.

“KDB has been impressive in assembling a group of very talented intellectual property attorneys, with a great deal of experience across many technologies and practice areas, including patent litigation,” said Ringel, referring to the firm’s network of lawyers throughout the United States. “Clients want a firm that will partner with them, provide innovative and strategic counsel, and be very cost-effective in doing so. KDB provides a modern platform for providing clients with high-quality and high-value services for today and for the future.”

Ringel is licensed to practice in the District of Columbia, New York, Florida (Board Certified Specialist in IP law), the U.S. District Court for the Southern District of New York, and the U.S. Court of the Appeals for the Federal Circuit. He received his law degree from the University of Michigan Law School and a degree in mechanical engineering from Cornell University.

Founded in 2003 by John Kacvinsky, formerly with an Am Law 100 firm and Intel Corp.’s in-house team, KDB was among the nation’s first law firms to focus exclusively on recruiting and retaining talent regardless of location. Through a well-connected network of attorneys nationwide, KDB keeps overhead low and client rates competitive while recruiting experienced IP counsel, most of whom were former in-house counsel, scientists and engineers.

In March, KDB announced the opening of shared-space offices in Boston and Washington, D.C. In August, the firm announced the arrival of two lawyers to its Massachusetts offices, Matthew Fagan and Steven Russell. Currently, the firm has five attorneys in the Washington, D.C. area.
