The accuracy and breadth of the keyword search directly impacts the results of the invalidation search and begins to isolate the invention described in the patent claims. Generating a keyword list, including synonyms and technical variations, is essential to effectively identify prior art.
In addition, an invalidation search strategy should include a careful review of the classifications in the patent database to capture all relevant prior art.
Understanding the invention and its elements
The first step is to review the invention described in the patent claims. This involves isolating the innovation into its elements. For example, if the patent is for a new type of battery, the main features may include the materials used, the energy density, the charging time, or the specific structural features of the battery cells.
Generate keywords
A keyword list, including synonyms, acronyms, and variations, is built from these found components. The search query is based on this list. Based on the battery example, keyword phrases may include phrases such as "fast charging", "high capacity", or "lithium-ion".
Here, the trick is to be both exhaustive and precise, ensuring that the search is targeted but also broad enough to find all relevant prior art.
Using patent classifications in invalidation searches
Patent classifications are extremely valuable when conducting a comprehensive invalidation search program. They help find patents in the same technical field and reveal prior art that cannot be found through simple keyword searches.
By using classification codes from the international patent system, you can simplify the search for relevant patents that may challenge the novelty of the patent.
Suppose a patent is applied for a drone with an improved stabilization system. Keywords include terms such as "gyro stabilizer", "aerial drone", "flight control". Categories may include broader categories such as drones or specific subclasses related to stabilization technology.
Include prosecution history in keyword generation
Reviewing the application history of a patent may generate more k bahrain phone numbers eywords and categories. Discussions between patent examiners and applicants are often included in this history, providing insight into how the claims were drafted and which areas were emphasized or disputed.
Conduct a broad and comprehensive search
To create a thorough invalidity search report, a broad and exhaustive search is required. Both patent and non-patent literature can provide valuable insights into the prior art that could challenge the validity of a patent.
Broad Search Approach
The first step is a broad search designed to provide a broad view of the prior art landscape using the identified keywords and classifications. By casting a wide net, a patent invalidation search helps assess the amount of existing information and refine subsequent steps in the search process.
For example, if the invention involves new data encryption technology, a broad search could include general terms such as "cryptography," "data security," and "encryption algorithms." This comprehensive approach helps estimate the amount of information that already exists and refine the search plan.
