   The roadmap to successful patent searching

   A patent search involves identifying existing patents and published patent applications related to the subject matter of interest. The search is conducted to determine the likelihood of obtaining a patent, assess freedom to operate, or challenge the validity of a granted patent. The process typically begins by utilizing free online patent databases, such as Google Patents, Espacenet and Patentscope although paid databases offer enhanced features and broader coverage.

   Various search strategies can be employed to locate relevant patent documents:

   a. Key string search: This strategy involves formulating search queries using descriptive keywords and synonyms associated with the invention. Operators like ‘OR’ and ‘AND’ are used to combine and connect the search terms effectively. Proximity operators can be employed to specify the distance between keywords. Refining the search gradually by expanding or narrowing the query can be helpful.

   b.  Patent classification search: Patents are classified into specific categories based on their technological subject matter. Identifying relevant classification codes, such as IPC or US patent classification, allows for a focused search within specific technology areas. Browsing hierarchical classification systems, using catchwords, or leveraging references found through other search strategies aid in identifying suitable classification codes.

   c.  Citation-based search: Citations refer to references cited by patent applicants or examiners. Analyzing backward and forward citations of relevant patents can lead to the discovery of additional relevant documents. Exploring the references cited within identified patents broadens the search further.

   d.  Assignee-based search: Extracting the names of assignees or applicants from relevant patent documents enables searching for patents associated with specific entities. Querying the database using the names of assignees/applicants can reveal patents held by those entities. Care should be taken to refine search queries to manage larger sets of results.

   e. Inventor based search: Extracting inventor names from relevant patents allows for searching patents associated with specific inventors. Searching the database using inventor names can uncover patents attributed to them. Similar to assignee-based search, refining search queries becomes important when dealing with prolific inventors.

By combining these search strategies iteratively and incorporating additional rounds of citation searches based on newly discovered references, the chances of uncovering relevant prior art are significantly improved.

The patent search process aims to provide a comprehensive understanding of the existing patent landscape and aid in decision-making related to patentability, freedom to operate, or patent invalidation.

Navigating the intellectual property maze: Exploring the diverse world of patent searches

Patent searches play a crucial role in the world of innovation and intellectual property. By uncovering existing patents, scientific literature, and technical publications, patent searches provide valuable insights into the prior art landscape, assess patentability, evaluate infringement risks, and inform strategic decision-making.

Let us delve into the various types of patent searches, each serving a unique purpose and demanding a different search strategy.

1. Novelty Search / Patentability Search / Prior Art Search: One of the most common types of patent searches is the novelty search, also known as a patentability search or prior art search. This search is conducted to determine if an invention meets the criteria of novelty and non-obviousness, and thus may be eligible for patent protection. By exploring existing patents, published patent applications, scientific literature, and technical publications, the search aims to identify prior art that discloses similar or identical inventions.
2. Validity Search: A validity search is performed to assess the validity of an issued patent. The search seeks to uncover prior art that was not considered during the patent examination process. By reviewing relevant prior art, the search aims to determine if the patented invention was truly novel and non-obvious at the time of filing. The results of a validity search can be used to challenge the validity of a patent in litigation or during post-grant proceedings.
3. Infringement Search: An infringement search focuses on assessing the risk of patent infringement. It aims to determine if a product, technology, or process may potentially infringe on existing patents. By comparing the claims of patents with the features of the product or process in question, the search helps evaluate the risk of patent infringement and informs strategic decision-making. An infringement search is often conducted before product launches or when assessing the viability of a new technology.
4. Clearance Search / Freedom to Operate Search: A clearance search, also known as a freedom to operate (FTO) search, is crucial for businesses and individuals before launching a new product or engaging in specific activities. It aims to assess whether a product, technology, or process may infringe on existing patents. The search involves exploring relevant patents to determine if the planned activities could potentially infringe on valid and enforceable patents. A clearance search helps mitigate the risk of patent infringement and informs strategic business decisions.
5. State-of-the-Art Search: A state-of-the-art search provides a comprehensive overview of existing technologies, trends, and innovations in a particular field. It aims to inform researchers, scientists, and product development teams about the latest advancements and emerging technologies. By analyzing patents, scientific literature, technical reports, and market research, the state-of-the-art search helps identify key players, assess market trends, and guide research and development activities.
