Understanding Patent Validity Opinion: A Key Legal Insight

Definition & Meaning

A patent validity opinion is a professional assessment provided by a patent attorney regarding the likelihood that a patent or a specific patent claim may be deemed invalid. This opinion is based on an analysis of various factors, including evidence of obviousness, lack of novelty, or unenforceability. In patent infringement cases, establishing a patent's invalidity is often the primary defense strategy. To start the process, one must first verify that the patent is still active, meaning the patent term has not expired and maintenance fees have been paid. If the patent is valid, a formal request for a patent validity opinion is made to the attorney, who will then evaluate all relevant materials and issue their findings.

The attorney analyzes the evidence and concludes that the patent may be invalid.

Example 2: A small business holds a patent for a unique product. They want to ensure their patent is secure before entering a licensing agreement. They obtain a patent validity opinion to confirm the strength of their claims and assess any potential risks. (hypothetical example)
