San Francisco’s Gray Cary has nudged aside Baker Botts to gain instruction
on the Cirrus Logic lawsuit that stopped the flotation of Wolfson
Microelectronics in its tracks.
The initial public offering (IPO) of Edinburgh’s Wolfson on the London
Stock Exchange, valuing the company at more than £213m, was due to
take place last week, making it the first major technology float of the
However, Wolfson, advised by Hale and Dorr, saw its plans delayed by the
Cirrus Logic suit, which alleges patent infringement on a number of the
semiconductor company’s designs.
Gray Cary’s Texas office won the job for Cirrus Logic after recruiting
intellectual property (IP) and IT litigation partner Alan Albright from
local firm Thompson & Knight in March 2001.
Thompson & Knight first encountered Cirrus Logic in 1999 following a
lawsuit involving the company’s subsidiary Crystal Semiconductor, advised
by the now defunct Brobeck Phleger & Harrison, and Texas semiconductor
However, since SigmaTel was already a Brobeck client, a federal judge
disqualified Brobeck from representing Crystal. As a result, Thompson &
Knight was brought in to act for Cirrus Logic on its next piece of work.
Aside from historical links, the departure of Cirrus Logic’s general
counsel Steve Overly six months ago also facilitated the new client win for
The general counsel is believed to have favoured Baker Botts’ Scott
Partridge, chair of the IP/IT practice in Houston and co-chair of the group
in Washington, and specialist partner Roger Fulghum.
Baker Botts represented Cirrus on settling patent disputes with NVIDIA
Corporation and ATI Technologies.
Wolfson’s contact partner at Hale and Dorr, Richard Eaton, shrugged off
the high-profile suit but it has caused the company to postpone its IPO
while it redrafts the prospectus.
“It’s perfectly normal in the semiconductor industry for companies with
lots of patents to sue each other. It is just part of doing business in
this industry,” said Eaton.
