We render hundreds of opinions a year ranging from a single opinion on a specific patent to providing long-term, ongoing counseling on complex patent portfolios or litigation. We routinely address patent validity, enforceability, freedom to operate (FTO), misuse, design-around issues, licensing potential, IP contract construction and enforcement, and export controls. We regularly partner with our clients’ legal, business, and technical staffs to identify the potential for risk and reward, from idea to revenue-generating portfolios.
In addition to transactional counseling, we routinely advise clients on prelitigation strategies. Our extensive litigation experience gives us firsthand insight into the various types of arguments opponents may raise. Combining our litigation and IP transactional experience allows us to help guide our clients to favorable settlements of disputes before or during litigation.
