Investing in London: Cooley keeps up City push with Olswang’s former PE head Rosen

After its mass hire from Edwards Wildman Palmer and Morrison & Foerster to launch in London earlier this year, Cooley has made good on plans to keep expanding in the City with the hire of Olswang’s longstanding corporate partner Stephen Rosen.

Rosen leaves Olswang after 13 years as a partner at the TMT firm, which included heading its private equity and venture capital group. During his tenure, he focused on acting for high growth companies, investors, and management teams on corporate transactions. He was also a member of Olswang’s life sciences group and regularly represented spin outs and VC funded companies in the life sciences arena.

Some of his key deals include advising the management team of RBS Aviation Capital on its $7.3bn sale to Sumitomo Mitsui Banking Corporation and representing Convergence Pharmaceuticals on its spin out from GlaxoSmithKline and fundraising of €35m by a group of European and US venture capital investors.

Olswang said in a written statement: ‘Corporate partner Stephen Rosen will be leaving the firm in due course to pursue new opportunities, following completion of the firm’s notice period.’

Rosen joins Cooley’s recently launched 55-lawyer UK practice which the firm established by taking partners from Morrison & Foerster and Edwards Wildman Palmer at the beginning of this year.

While Olswang’s partnership was served a blow in October last year after its former chief executive David Stewart stepped down, the firm has made positive strides this year, and hired intellectual property partner duo from US firm Winston & Strawn in February, as well as appointing its senior corporate TMT Partner Mark Bertram as its new head of corporate.
