Definition
Patent litigation is the legal process of resolving disputes over patent infringement or validity in court, often involving substantial time and expense.
Why It Matters Legally
Litigation is the ultimate way to enforce a patent or clear a product, but it is expensive and unpredictable. The high cost shapes whether parties fight, settle, or pursue cheaper alternatives like PTAB proceedings.
Example Use Case
A patent owner sues a competitor in federal court, leading to years of discovery, a Markman hearing, and eventually a trial on infringement and validity.
