Consider a patent for a new type of optical sensor. A broad search might start with general terms such as “optical sensing,” “light sensing,” and “sensor technology.” It will include various databases and sources, as well as a variety of related technologies.
Switching to comprehensive search
Following the broad search is the exhaustive search. This search is narrower and deeper; it searches patent databases and publications.
It involves exploring non-patent databases, including IEEE Xplore, ScienceDirect, etc., as well as patent databases, such as USPTO, OPE, WIPO, and Google Patents. The goal is to find prior art that existed before the priority date of the patent and that may cast doubt on its novelty or lack of obviousness.
Techniques for effective comprehensive search
Exhaustive search is leveraged using a variety of techniques, including keyword and classification search, citation analysis, and semantic search. For example, for optical sensors, the search will now focus on specific sensor types, detailed technical aspects, and application areas, filtering the search to be as targeted as possible.
Importance of document line break analysis
It is necessary to examine the patent folder, which is a record of correspondence between the applicant and the patent office, and consult external sources. In-depth information about the patent, including any rejections, applicant arguments, and claim amendments. This information can be used to discover any weaknesses or relevant prior art.
Strong invalidity searches are often associated with non-patent literature (NPL). Sources such as scientific journals, conference proceedings, and industry reports can uncover prior art that may be missing from patent databases, providing critical evidence to invalidate a patent.
By expanding invalidity searches beyond traditional patent databases, you may find documents that disclose technologies or methods similar to those claimed in a patent, potentially invalidating its claims.
Understanding Non-Patent Literature
Non-Patent Literature includes a variety of documents and publications, such as scientific journals, conference proceedings, technical reports, textbooks, blogs, and online resources. These sources often con bahrain telephone numbers tain detailed technical information and innovative ideas that preceded a patent application.
The Role of NPLs in Patent Invalidation
In many cases, NPLs can provide evidence of prior art that challenges the novelty or non-obviousness of a patent claim. For example, a journal article or conference paper may describe a technology or process similar to that claimed in a patent, undermining its validity.
Example: Using Scientific Journals
Consider a patent for a new compound for use in a drug. Although patents are limited, searching in scientific journals may find research papers discussing similar compounds or their derivatives that may have existed before the patent application.
Databases for NPL Search
An effective NPL search typically involves databases such as IEEE Xplore, ScienceDirect, SpringerLink, and Google Scholar. Each database provides access to a different set of resources, covering different technical and scientific disciplines.
Expanding the Search Horizon
In addition to academic journals, other resources such as technology blogs, industry reports, and news articles can also
