Non-Infringement Opinion

A Non-Infringement Opinion is a legal analysis prepared by patent or IP counsel concluding that a proposed product, process, or service does not infringe existing intellectual property rights (usually patents). The opinion analyzes relevant patents, compares patent claims to the proposed product, and concludes whether infringement exists. Obtaining a non-infringement opinion before launching a product demonstrates due diligence and good faith, which can prevent a finding of willful infringement (which can result in treble damages in patent cases). The opinion includes: identification of relevant patents, claim construction (interpreting claim language), analysis comparing claims to the product (literal infringement and doctrine of equivalents), and conclusion. While not a guarantee of non-liability, a well-reasoned opinion from competent counsel provides significant protection and helps companies make informed business decisions about product development and market entry.
