Best Practices for Patent Search in India

 1. Understand the Types of Patent Searches

- Novelty Search: To determine if your invention is new.

Freedom to Operate (FTO) Search: To ensure your invention doesn’t infringe on active patents.

- Validity/Invalidity Search: To check the enforceability of a patent’s claims.

State of the Art Search: To understand the current advancements in your field of invention.

2. Use Multiple Databases

Utilize various databases for a comprehensive search. The Indian Patent Advanced Search System (InPASS) is the primary database. However, also consider international databases like the USPTO, EPO, and WIPO to get a broader view of existing patents.

3. Keyword Selection

Identify relevant keywords, IPC (International Patent Classification) codes, and CPC (Cooperative Patent Classification) codes related to your invention. Use synonyms and related technical terms to broaden your search.

4. Analyze the Results Thoroughly

Review the abstracts, claims, and detailed descriptions of the patents you find. Look for similarities and differences between these patents and your invention.

5. Keep an Eye on Legal Status

Check the legal status of patents to identify if they are active, expired, or abandoned. This information is crucial for freedom to operate searches.

6. Document Your Search Process

Record your search queries, databases used, keywords, and findings. This documentation can be valuable for your patent application process and future legal needs.

7. Consider Professional Help

Patent searches can be complex. Consider hiring a patent attorney or a professional patent searcher, especially for freedom to operate searches, which require extensive legal knowledge and expertise.
