Opposition/ Invalidity Search
IP Intelligence
An opposition or invalidity search is a valuable tool for assessing the strength and enforceability of an existing patent. By identifying relevant prior art and evaluating its potential impact on patent validity, we help clients make informed decisions in opposition proceedings, litigation support, and competitive intelligence activities.

Our approach, step by step
- 1
Patent Review & Search Strategy
Each project begins with a detailed review of the patent under consideration, including its claims, prosecution history, and technical subject matter. Based on this assessment, we develop a tailored search strategy focused on identifying prior art most relevant to the validity of the challenged claims.

Prior Art Search
Using a combination of keyword, classification, citation, semantic, and inventor-based search techniques, we conduct a comprehensive search of patent and non-patent literature. Our objective is to uncover references that may call into question the novelty or inventive step of the patent claims.

Prior Art Analysis & Validity Assessment
Identified references are analyzed against the claims of the patent under review. We evaluate the relevance and strength of the prior art and assess its potential impact on patent validity, helping clients understand the likelihood of successfully challenging or defending the patent.

Reporting & Strategic Insights
Our findings are presented in a clear and practical format tailored to the client's objectives. Depending on the level of support required, results may be delivered as a standalone search report or accompanied by a detailed review and strategic assessment. Where appropriate, we also highlight potential opposition grounds, evidentiary considerations, and areas requiring further investigation.
