International Patent Novelty Search Before Filing: Tools and Procedures

Prior art is what breaks or proves your invention's novelty. A professional search reveals whether your invention is "actually new" before investing in formal procedures.

Open Databases

Espacenet (European Patent Office): the most comprehensive internationally, free, English.

USPTO Patent Search: the U.S. database.

WIPO PatentScope: unified international databases.

Google Patents: easy interface aggregating from multiple sources.

Search Methodology

Identifying precise technical keywords.

IPC (International Patent Classification) categories relevant to the invention.

Searching in multiple languages (English, German, Japanese).

Citation review: patents referring to patents.

Professional Search Report

List of relevant prior art with links.

Similarity grade assessment per reference.

Analysis of your invention's patentability.

Recommendation: proceed, amend claims, or abandon.

Cost

Self-search: free but not comprehensive.

Professional search: SAR 2,000–8,000 (Saudi/Gulf).

Comprehensive international search: SAR 10,000–20,000 (worth it for major innovations).

Advice

Do not file a patent without novelty search. The extra cost is 5–10% of the application cost — but saves you from losing the other 90% in a failed application.
