The Importance of Prior-Art Search: A Guide to Effective Patentability Search
When considering filing a patent application, whether as an individual inventor, university, startup, or corporation, conducting a thorough pre-filing search is crucial. A prior-art search—also known as a patentability search or novelty search—helps determine whether an invention is new and non-obvious, key requirements for patent eligibility.
A well-executed prior-art search not only saves time and resources but also strengthens the patent application, improving its chances of approval. Below, we outline key search methodologies used for identifying prior art efficiently and effectively.
Key Search Methodologies for Prior-Art Search
1. Keyword Search
One of the most common approaches, keyword search involves using specific terms related to the invention to locate relevant prior art. This search can be performed using different strategies:
- Narrow Keyword Search – Focused on specific sections like the title, abstract, and claims.
- Broad Keyword Search – Covers the full text of patents and publications.
- Keyword Search with Near Operators – Uses Boolean operators to refine searches based on proximity and relationships between words.
2. Classification Search
Patent office’s categorize inventions into classification systems like CPC (Cooperative Patent Classification), IPC (International Patent Classification), and US Classes. Searching within relevant classifications ensures a more precise and comprehensive search.
- Unrestrained Core Class Search – Searches within the core classification of an invention.
- Core Class & Keyword Search – A combination of classification and relevant keywords to improve search accuracy.
- Combined Peripheral Class & Keyword Search – Expands the search by including peripheral classifications that may be relevant to the invention.
3. Bibliographic Search
Bibliographic searches focus on patent metadata, such as inventors, assignees, and entities involved in prior inventions. This search is useful for understanding competitors and tracking technological advancements.
- Assignee/Entity Search – Searches patents owned by specific companies or organizations.
- Inventor/Author Search – Focuses on patents and publications associated with specific inventors.
- Combination Searches – A mix of keyword, classification, and assignee/inventor searches to enhance precision.
Why a Professional Search Matters
While free and paid databases are available for conducting prior-art searches, the complexity of patent search methodologies requires expert knowledge and strategic execution. Professional searchers leverage specialized paid databases and advanced techniques to deliver comprehensive and accurate results, significantly impacting the decision to file a patent application.
Investing in a well-researched prior-art search reduces the risk of patent rejections and provides clarity on an invention’s uniqueness. If you’re considering a patent filing, ensure that your innovation stands on solid ground by engaging professional expertise in prior-art search.
