Two partners join Arnold & Porter IP team

Washington DC firm Arnold & Porter is taking on two new partners to boost its anti-trust and intellectual property (IP) teams.

Donna Patterson, the deputy assistant attorney-general in the anti-trust division of the US Department of Justice, is returning to the firm after three years in public office. Patterson was then on Arnold & Porter’s management committee.

Patent litigation partner Joseph Micallef is joining the intellectual property group in Washington from Howrey Simon Arnold & White, one of the world’s largest IP firms.

Patterson has been reviewing M&As in the defence industry, healthcare and communications sectors while at the Department of Justice. She says she is returning to private practice because it is an election year, and the attorney’s role there is generally a political appointment rather than a civil servant position.

Micallef’s practice focuses on representing technology companies in patent disputes. In the past his clients have included Intel and Samsung.

He says the move into a patent litigation team of 11 lawyers provides a better opportunity to develop his practice than in Howrey’s 40-lawyer team.
