Markman Hearing

Definition

A Markman hearing is a pre-trial proceeding in a patent infringement lawsuit where the judge interprets the meaning of the key terms or claims in the patent. This interpretation of the patent claims is critical in determining the scope of the patent and the boundaries of the invention, which in turn affects the outcome of the infringement analysis.

• Analyze the relationship between the Markman hearing and the broader context of patent litigation, specifically the pretrial procedures and the determination of patent infringement.
  • The Markman hearing is a key component of the pretrial procedures in a patent infringement lawsuit. It occurs early in the litigation process, often before discovery is completed, to provide the court's interpretation of the patent claims. This claim construction established in the Markman hearing is crucial because it defines the boundaries of the patented invention, which directly affects the infringement analysis. The judge's Markman ruling will guide the rest of the case, including summary judgment motions, expert reports, and the ultimate trial. If the court's claim construction is favorable to the patent holder, it can increase the likelihood of a finding of infringement.
