IMPORTANT: Patent analysis is not legal advice. Always consult a licensed patent attorney for FTO opinions and filing decisions.

Patent Search Strategy

Search Sources

• USPTO Patent Full-Text Database: US patents and applications
• Espacenet (EPO): worldwide patent coverage
• Google Patents: best for keyword-based initial searches
• Lens.org: open access, cross-database
• PatSnap / Derwent (enterprise): analytics and citation mapping

Search Methodology

1. Define the invention in function terms (not your specific implementation)
2. Identify: core concept, key components, novel aspects
3. Build keyword set: synonyms, technical terms, trade names for each concept
4. Search CPC/IPC classifications most relevant to the technology
5. Review 50-100 most relevant results for relevance
6. Expand search based on cited references and citing patents

Claim Analysis

Claim Hierarchy

• Independent claims: stand alone, define broadest scope, must all be valid
• Dependent claims: narrow the independent claim, easier to defend

Claim Element Analysis

For FTO: infringing product/process must include EVERY element of an independent claim. Missing even one element = no infringement of that claim.

Patent Landscape Analysis

For a technology area, map:

1. Key assignees (companies/universities) and their portfolio size
2. Filing trend by year: is the space getting crowded or quieting down?
3. Most cited patents: foundational prior art (design around or license?)
4. White space: technology combinations with few or no filings
5. Expiring patents: valuable patents entering public domain
