US Patent Search (Major Search Types)

It is essential for one to conduct a US patent search before the patent filing process. It is so because patent search plays a huge role in avoiding patent infringement. This, subsequently, reduces the cost of the applicant.

A US search is a subset of the prior-art search. Here, one mentions similar ideas in academic and technical literature. If one has got an amazing idea then he first needs to search the patentability status of that idea. Then only he can move further and get a patent if no one has got legal rights of that idea.

US Patent Search: Types

As patent search involves exploration of the issued patents so one considers it as an important prior art reference. Some types of US Search are:

Prior Art/Novelty Search

This determines if prior-art exists that would prevent an idea or invention from being patented. The attorneys and patent agents search for any pre-existing documents. These documents are the ones that a patent examiner would likely use against a patent application during the examination. The search uncovers relevant documents including U.S. and foreign patents, published patent applications and non-patent printed publications. For example, thesis papers and dissertations.

Validity Search

This determines the validity of an issued patent by locating any prior-art documents or references that would invalidate the claims of interest.

This search focuses on documents predating the priority date of the patent in question. In addition, the attorneys also review the file history to best understand the points of novelty.

Infringement Search

It is one of the best ways to do a US based patent search. This compares a client’s proposed product or idea. And, also determines whether any patent claims read on the client’s proposed product or method.

The search uncovers relevant U.S. patents and published patent applications. And, as a result one can expand it to include foreign patents and patent applications.

Clearance Search

This is similar to an infringement search. But it also looks to uncover expired prior art documents. Clearance searches are also known as “freedom-to-use”, “freedom-to-practice” or “right-to-use searches”.

State-of-the-Art Search

One conducts this search when a broad and general inventive concept must be given a final and precise embodiment.

Based on the broadness of the proposed product, idea or method, one may uncover a large number of references. They may range from U.S. patents to published patent applications.

Collection Search

This locates U.S. patents still in force, published patent applications and also expired patents in the public domain for the specific subject matter.

Database and Electronic Searching

This search requires one to perform in-house database-driven research. This search, as a result, locates relevant U.S. and foreign patents. It also locates relevant documents, articles, brochures, dissertations and other items.

Also, this search requires compilation to one of the most extensive collections of database resources.

Manual Patent Search at UPSTO Database

This comes as one of the most significant US patents searching method. The patent applicant can search for the patent manually at the USPTO. A manual search includes a review of patents and published patent applications.

Thus, one can classify the search in a particular class or across multiple areas covering the technology. This manual search method includes on-site research in the search room of the USPTO along with personal consultation with patent examiners.

Library Searching

In addition to the databases and archives of the USPTO, one can search for relevant prior art and documents across several library resources. The non-patent libraries include the Library of Congress, National Library of Medicine at the National Institutes of Health and the local technical libraries.
