Patent Validity

Definition

Patent validity refers to whether an issued patent satisfies all legal requirements and would survive a challenge in court or before the PTAB.

Why It Matters Legally

Even granted patents can be invalidated, so validity is always in play during enforcement. A patent owner’s leverage depends heavily on how likely the patent is to hold up under attack.

Example Use Case

Before suing, a patent owner commissions a validity analysis to gauge how vulnerable its patent might be to an invalidity challenge.
