Jones Day has added a former Akin Gump Strauss Hauer & Feld energy partner and a former Perkins Coie IP partner to its Washington office along with a tax attorney from PwC.

David Applebaum and Michael Oblon have joined the firm as partners from the competitor law firms. The third lawyer is Amie Colwell Breslow, who joined Jones Day as of counsel in its tax practice.

The additions come at a time when the global firm is in the spotlight for testimony a partner, Don McGahn, gave special prosecutor Robert Mueller III concerning McGahn’s former position as White House counsel. McGahn has since returned to Jones Day.

The 2,500-lawyer firm has more than a dozen of its former lawyers working in the current administration, and represented Donald Trump’s presidential campaign.

Applebaum, who was a partner at Akin Gump, represents energy industry clients in regulatory enforcement matters before the Federal Energy Regulatory Commission and at other agencies, and in complex civil litigation and internal investigations. He served for six years at the commission as director of the division of investigations in the Office of Enforcement.

His clients have also included natural gas providers, power traders, utilities, and other market participants in the commission’s market manipulation investigations and in energy-related litigation. He has advised energy companies on proposed trading and other business strategies to avoid or mitigate compliance risk.

“David’s experience at the FERC and his high-level client representations give him particularly good insight to the compliance and enforcement matters that confront our energy clients,” Jeff Schlegel, head of Jones Day’s global energy practice, said in a statement.

Oblon, who had focused on patent and trade secret litigation at Perkins Coie, also brings experience in strategic counseling for technology companies that develop software, electronics and electromechanical products. He has secured settlements totaling over $65 million for plaintiffs.

Oblon founded Perkins Coie’s East Coast IP practice in 2006.

“As innovation continues to drive the global economy, it is essential to provide our clients with counselors, like Michael, who have deep experience litigating highly technical patent and trade secret cases,"said Anthony M. Insogna, head of Jones Day’s global intellectual property practice, in a statement. He added Oblon’s hire expands the firm’s IP litigation and counseling capabilities in the electronics industry.

Breslow has more than 20 years of experience in international tax planning. She most recently worked at PwC where she advised clients on domestic and cross-border mergers, acquisitions, integrations and spin-offs as well as the pre-sale restructuring of assets and operations.

She also served as senior tax counsel at GE, and as an attorney-adviser for the IRS. According to a statement by Joseph Goldman, co-head of Jones Day’s tax practice, Breslow brings “seasoned experience with handling complex, multi-jurisdictional transactions and implementing global projects.”
