Intellectual Property Litigation

Greenfield provides experienced and skilled trial lawyers from elite BigLaw intellectual property practices, and scales internally with lawyers who have litigation and trial experience necessary to prosecute or defend the case. We work with an established and nimble network of specialists in patent law and electrical, mechanical, computing and life science technologies.

We have deep expertise across all facets of technology and innovation litigation, including:

  • Patent infringement
  • Post-grant review of issued patents (IPRs)
  • Trade secret misappropriation
  • Technology license disputes
  • Technology development and supply  agreement disputes
  • Technology company disputes (founders and investors disputes; shareholder derivative actions; and breach of fiduciary duty by key employees, founders, directors, officers or  controlling shareholders)
  • Copyright infringement
  • False advertising
  • Trademark and trade dress infringement
  • Internet speech disputes (First Amendment, privacy, defamation, anonymous online posts)
  • Deceptive practices and unfair competition

We handle these disputes in trials, appeals and arbitrations in federal, state and appellate courts as well as other venues across the country. This includes judicial districts with patent-intensive dockets, such as the District of Delaware, Northern District of Illinois,  Eastern District of Texas and the Northern and Central  Districts of California.

Our clients range from billion dollar technology companies to individual inventors and entrepreneurs, both as plaintiff and as defendant. Greenfield serves its clients across a vast array of advanced technologies in the electrical, mechanical, computing and life science arts, including: industrial design; implantable medical devices; surgical tools and related devices; genetic testing products for consumers; wireless headsets and other wireless/wearable  communication devices; systems-on-chips; digital signal processing; integrated circuit fabrication and testing; semiconductor capital equipment; RF/microwave circuits; bluetooth and Wi-Fi applications; PCB design and circuits; computer aided design; optics and reflective imaging; networking infrastructure; e-commerce applications; online data storage; ISP technologies and related CRM software; and low voltage mini and micro focus x-ray tubes.

Lower, Predictable Costs

Our clients are sensitive to the high cost of patent and other types of intellectual property litigation, but also require the highest quality legal services for their matters. Greenfield  addresses both issues by using small teams of senior, skilled trial lawyers, unbundling services and leveraging technology and strategy to bring about faster resolutions. We also use flat fees and other non-hourly based fees to align our economic interests with our clients.  As a result, clients receive better, more effective service for lower, predictable costs.
