Invalidity & Validity

Challenge patent validity with prior art evidence.

Invalidity & Validity

An Invalidity or Validity search is an exhaustive investigation to uncover “prior art”—critical evidence that an invention was already known before a patent was filed. This deep dive into the global archives of technical knowledge serves two distinct but vital purposes. It is used offensively to challenge a competitor’s patent and defend against infringement claims (Invalidity), or defensively to confirm the strength and enforceability of your own patent assets (Validity).
At Signicent, we are your expert investigators in these high-stakes searches. Our team understands that finding the single piece of prior art that can change a legal outcome requires a meticulous, multi-pronged strategy. We dig deep into global patent databases, scientific literature, and obscure technical documents to find the crucial evidence you need. We provide the well-documented ammunition required to support your legal or business case with confidence.
