Services
One practice, end to end.
The attorneys who draft the patent are the ones who defend it at the Board and try it in district court. That loop is the whole argument for a firm this focused.
Patent Prosecution
Drafting and prosecuting patents that survive contact with examiners, competitors, and courts.
Patent Office Trials
Inter partes review and post-grant proceedings, on both sides of the caption.
Litigation
Patent and IP disputes in the district courts, the ITC, and the Federal Circuit.
Opinions & Diligence
Freedom-to-operate, invalidity and non-infringement opinions, and transaction diligence.
Trademark
Brand clearance, worldwide procurement, oppositions, licensing, and domain name matters.
Technology Transactions
Licensing, joint development, and the IP terms inside technology agreements.
Strategic Patent Ideation
Building patent portfolios around where the business is going.

People
Search by what someone actually knows.
Most firm directories filter by office and practice group. Ours filters by technical discipline, degree level, field of study and forum — because the question clients actually ask is which of your people understands this technology.
