Oblon Spivak McClelland Maier & Neustadt is a top filer of patent applications in the US, with much of its clientele originating overseas. Toyota, Toshiba, and Mitsubishi Electric are some of its clients. "It's probably one of the biggest prosecution houses in the country," said a competitor. "It has managed to make a science profitable with a lot of foreign prosecution." The firm has placed particular emphasis on reexaminations, dedicating a practice group helmed by Stephen Kunin, former USPTO patent examination policy deputy commissioner, to the proceeding. "It is an excellent team," said a client, naming managing partner Richard Kelly and Jean-Paul Lavalleye as top attorneys.
The firm was elevated in the trade mark prosecution rankings this year, following strong feedback from peers. "The people know what they're doing," said a competitor. He added: "I'm understating that. They really know what they're doing." A client praised the group's "high professional competence," adding that it was "very experienced, responsive and reliable".
