Invalidity Search Services
An invalidity search is a targeted investigative process designed to identify prior art that pre-dates a patent's priority date. Often deployed during contentious litigation, licensing negotiations, or high-stakes diligence, it provides in-house counsel and litigation teams with the technical evidence required to challenge the validity of specific patent claims.
While related to patentability and Freedom to Operate (FTO) work, invalidity searches focus strictly on establishing the prior existence of claimed inventions to establish strategic leverage. This research serves as a foundational risk assessment tool, informing informed enforcement or defense decisions across diverse jurisdictions and technology sectors.
Common Triggers
Receipt of Threat Letter: Evaluate claim validity immediately upon receiving potential infringement notifications or formal demand letters.

Frequently Asked Questions
What is the typical scope of an invalidity search?
The search scope focuses on identifying relevant prior art—including granted patents, published applications, and non-patent literature—that predates the target patent’s priority date to evaluate validity on novelty or non-obviousness grounds.
How long does a standard investigation take?
Standard investigations are typically finalized within 5 business days. For urgent litigation matters or deal deadlines, we offer expedited timelines that maintain our rigorous search methodology.
How do you collaborate with outside counsel?
Our analysts function as a technical extension of your team, providing structured data and granular claim charts that legal counsel can readily incorporate into their formal litigation or licensing strategies.
Can searches prioritize specific global jurisdictions?
Yes. While we maintain global database access, we can tailor the search strategy to prioritize specific technology centers, languages, or regional offices based on the target patent’s family and the geographic scope of your matter.
Do you provide legal opinions on validity?
We provide exhaustive technical investigations and detailed mapping of prior art. These high-fidelity results provide the intelligence necessary for qualified legal counsel to render formal validity opinions and legal strategy.
