Intellectual Property


Companies around the world turn to us for their most important intellectual property and dispute resolution matters. We guide our clients through difficult issues, bringing our technical acumen, decades of experience and judgment to each situation. Our innovative approaches create original solutions to our clients' most complex domestic and multijurisdictional disputes.

Global contentious proceedings

Our team develops and coordinates litigation and enforcement strategies across the US and Europe. We ensure that enforcement strategies taken in one jurisdiction do not present conflicts in another. Clients call on our team to coordinate opposition and various national office proceedings in Europe with US litigation proceedings in district, federal and appellate courts. We present genuine depth and local law capability that few other firms can match. With IP practitioners strategically placed with the ability to act throughout our Firm's global network, White & Case is uniquely situated to assist clients with their IP needs.

Our patent practitioners have a multifaceted practice

Having been in the courtroom for patent litigations and negotiated complex patent license agreements, our patent practitioners have the perspective of a litigator. We routinely advise clients on structuring their patent portfolios to cover competitor products with valid claims that can survive litigation. We also have the view of a transactional lawyer (e.g., how patent assets may be evaluated in a business transaction), and of a business counselor (e.g., how the patent may best meet our clients' business needs).

Global strategic patent counseling

We collaborate with our clients to develop and manage their patent portfolios from a global perspective. Our first port of call is structuring clients' patent portfolios to meet the legal requirements of the US, Europe and other major markets, and extends through all phases of procurement. We routinely work with regulatory counsel to understand the interplay between regulatory and patent exclusivities and specialize in having an eye toward highlighting potential loss of exclusivity and risk mitigation strategies.

Key to our team – our cross-border IP capabilities

Our team has a unique international approach—we have dual-qualified lawyers who are both US lawyers and English solicitors, and we practice routinely before the USPTO, the European Patent Office and the UK High Court. Our practice thus combines a sophisticated understanding of the legal frameworks in the US, Europe and the UK, with unparalleled technical and scientific expertise to provide strategic cross-border legal advice. 

As in-house technical experts, we understand your business

Many of our lawyers and patent analysts hold advanced degrees and have specialized training in scientific and technical fields, including in molecular biology, synthetic organic chemistry and biochemistry, among other subjects. Our team leverages its experience across different technical and engineering disciplines to master the technology, file histories and prior art, and is able to provide exceptional, economical solutions to complex legal and business issues.

PTAB and IPR expertise

  • We routinely use IPR proceedings as an adjunct to defensive patent litigation proceedings and are adept at fending off the same in offensive patent litigation proceedings
  • We are a leader in helping clients protect and invalidate patents in US Patent Office post-grant proceedings, including inter partes review (IPR), covered business method (CBM) review and post-grant review (PGR) proceedings
  • Our market-leading PTAB practice enables a complete solution for patent clearance, protection and monetization
  • Our lawyers are patent litigators and have negotiated complex patent license agreements and routinely counsel clients on all aspects of patent matters
