The Landscape of Patent Invalidation
What is Patent Invalidation?
Patent invalidation is the process of proving a patent is not novel or non-obvious based on prior art. It plays a central role in litigation, oppositions, and due diligence.
Why Search Tools Matter
Invalidating a patent requires access to prior art across jurisdictions, proper legal context, and the ability to document and present findings. The right search tool can streamline this process significantly, especially when coupled with automation and semantic insight.
The Lens Patent Search: Overview
Origins and Mission
The Lens is a nonprofit platform developed by Cambia and the Queensland University of Technology. It aims to democratize access to patent and scholarly information for both professionals and the public.
Core Features
- Access to over 127M+ patent records from 95+ jurisdictions
- Integration with 200M+ scholarly articles
- Transparent legal status tracking
- Powerful Boolean, proximity, and fielded search
Notable Tools
- PatSeq Finder: BLAST-based biological sequence searching
- Citation Tree and Patent Family Analysis
The Lens is particularly strong for researchers in life sciences, academia, and global innovation mapping.
PatentScan: Overview
AI-Powered Innovation
PatentScan is a commercial platform tailored for IP attorneys, paralegals, and legal analysts. It uses natural language processing (NLP) and AI to simplify patent analysis.
