A patent search is a crucial step for inventors and businesses looking to protect their intellectual property. It involves searching existing patents to ensure the novelty of an invention and avoid potential infringement. This process helps identify prior art, assess the likelihood of patent approval, and can guide future innovation strategies. Understanding how to conduct a patent search is vital for safeguarding ideas and ensuring legal protection for inventions.
A patent search checks if an invention is new by verifying existing patents or applications. It is done using tools and databases to ensure originality, avoid infringement, and support strong patent protection. It helps avoid patent infringement issues. Vakilsearch offer professional patent search services ensuring that the patent scope is well-defined.
History of the Patent System in India
The history of Indian Patents began in 1856 when the first patent act was proposed under the 1852 British Patent Act, providing exclusive rights to inventors for 14 years. With time, the patent system increasingly aligned with the economic and industrial growth of India, mirroring the country’s increasing demand for protection of innovations.
The Indian Patents and Designs Act 1911 represented a transition as it centralized the administration of patents, abolishing regional patterns. Post-independence, the 1970 Patent Act hugely influenced the country’s patent regime with its emphasis on promoting indigenous innovation as well as controlling monopolies, especially in pharmaceuticals and chemicals.
A landmark shift was introduced with the Patents (Amendment) Act of 2005, bringing India in line with the World Trade Organisation (WTO)’s TRIPS Agreement, allowing product patents in all fields of technology. The Indian patent regime is now overseen by the Controller General of Patents, Designs & TradeMarks (CGPDTM), which has witnessed a consistent increase in patent filings, with more than 80,000 filings per year as of 2023, indicating India’s growing emphasis on research and innovation.
Why is a Patent Search Important?
A patent search is important in ascertaining the novelty and nonobviousness of an invention, key requirements for the issuance of a patent. It also helps in preventing infringement of other patents, keeping inventors’ innovations free from legal complications.
Benefits of a Patent Search:
- Patentability Analysis: Identifies similar prior inventions, ensuring the idea is new and unique
- Preventing Infringement: Prevents accidental infringement of others’ intellectual property
- Strategic Decision-Making: Determines whether or not to obtain a patent and what scope of protection
- Making patent applications stronger: Helps inventors draft stronger, more readable patent applications
- Competitive intelligence & market research: Provides insights into competitors and emerging technologies
- Uniqueness of technical information: Patents contain specific, hard-to-obtain technical information
- Avoiding duplication: Prevents researchers from duplicating existing solutions
- Genealogy & history: Patents can be useful in genealogical and historical research.
According to WIPO (World Intellectual Property Organization), global patent filings exceeded 3.5 million in 2023, indicating the increasing importance of intellectual property protection. Since India witnessed over 80,000 patent applications annually, conducting a patent search is more important than ever to stay competitive and within the law.
Types of Patent Searches
Patent searches are varied, and each of them plays a specific role in the intellectual property (IP) process of innovation. Ranging from identifying an invention’s novelty to ensuring market freedom or countering existing patents, the right type of search can avoid businesses’ legal battles and loss of money. The most common kinds of patent searches and how they are used are given below.
-
Patentability / Novelty Search
A patentability search (or novelty search) determines whether an invention is novel enough to be patented. It searches across global patent databases and non-patent literature to detect prior art—any prior-occurring technologies or publications similar to the proposed invention. This search notifies inventors of their chances of obtaining a patent and assists them in building their applications for a stronger claim.
Example: A tech startup developing an AI chatbot would conduct a patentability search to ensure their innovation is not already patented before submitting an application.
-
Freedom to Operate (FTO) Search
An FTO search is conducted to determine whether an invention can be legally manufactured, sold, or used within a specific region without infringing on existing patents. Unlike a patentability search conducted on fresh inventions, FTO searches investigate live patents in order to avoid legal disputes.
Example: A pharmaceutical company releasing a generic of medication must conduct an FTO search to be certain that no active patents will restrict its sale or manufacture.
-
State of the Art Search
A cutting-edge search provides an overview of recent technologies and trends in a particular sector. It is extensively used by R&D teams, startups, and businesses looking to research new concepts or improve products. A search like this does not focus on a single invention but on describing technology advancements in an area.
Example: A car manufacturer conducting research on electric vehicle (EV) batteries would perform a state of the art search to learn about recent developments and areas of improvement.
-
Invalidity Search/Validity Search
An invalidity search (or validity search) is conducted to invalidate or establish the validity of a patent already granted. A search of this type is useful in patent litigation where a company or individual wishes to invalidate a competitor’s patent by finding prior art that was not caught during the patent search.
Example: If a company is being sued for patent infringement, they might do an invalidity search to uncover evidence that the patent never should have been issued in the first place, hopefully undermining the lawsuit.
Steps to Conduct a Patent Search
Conducting a patent search is essential before filing a patent application to ensure novelty and avoid infringement. By following a structured process, inventors can efficiently determine if their idea is unique and protectable.
- Step 1: Setting the Scope – Prior to patent search, one should define its purpose. Consider whether the target is to gauge patentability, freedom to operate (FTO), or earlier art. Laying out the technical area and industry of invention assists in delineating search criteria. Also decide whether the search would be for world patents or on a country basis (e.g., USPTO for United States patents, EPO for Europe).
- Step 2: Keyword and Classifications – A clear keyword strategy is important for an efficient patent search. It entails applying synonyms, technical jargon, and Boolean operators (AND, OR, NOT) to narrow searches. Using patent classification codes aids in categorising inventions systematically.
- Step 3: Examining Search Results – Once results are collected, it is crucial to assess the relevance and novelty of the results. Reading abstracts, claims, and drawings aids in deciding how well current patents resemble the new invention. Verification of the legal status of patents—active, expired, or pending—provides a clearer picture of existing patents.
Benefits of Conducting a Patent Search
A patent search ensures the novelty of an invention and protects inventors from possible legal disputes. It also provides insightful information for strategic decision-making and fortifies patent applications. Here are 5 advantages of the same:
- Cost-Effectiveness: Prevent Expensive Mistakes – A comprehensive patent search saves businesses from spending enormous amounts of money in the form of rejected patent filings or lawsuits. Conducting an exhaustive search beforehand saves businesses from losing money by working on unfeasible patents.
- Risk Mitigation: Reduce Legal Risks – Litigation over patent infringement is costly and may damage a company’s reputation. An effective patent search uncovers existing patents and reduces the chance of unwittingly infringing intellectual property rights.
- Strategic Advantage: Improve Market Position – A patent search allows businesses to analyse the competition and optimize their innovation strategy. By learning about existing patents, businesses can develop unique technologies, avoiding areas patented and focusing on market loopholes. Apple and Samsung are two of the top tech firms that conduct frequent in-depth patent searches to analyse competitors’ portfolios and maximise R&D investment.
- Improve Patent Approval Success Rates – The USPTO denies around 45% of patent applications due to conflicts with prior art. A thorough patent search improves approval rates by establishing the novelty of an invention before filing. Firms making searches beforehand can prepare applications particularly aimed at introducing unusual aspects, which reduces rejection and the cost needed for further alterations.
- Enable Investment & Funding Opportunities – Venture capital firms and investors favor companies that have a well-developed intellectual property (IP) strategy. A patent search is a sign of industriousness and makes an investment less risky when using technology that has the possibility to be challenged legally. According to research, firms that have a good patent strategy receive up to 35% more in financing than companies lacking a good IP strategy.
