🗎 Expert evidence is generally used in patent oppositions before the Court, to provide evidence as to how the person skilled in the art would interpret the patent specification being opposed or that being enforced. Such evidence can be wholly determinative of the findings of validity and infringement and is often crucial to the outcome of patent litigation.
