Patent, Prior Art, Novelty, & Patentability Search Services.

What is a Prior Art Search? 

Patent Search Services (Prior Art Searching) is research to find all the products and inventions similar to an invention that you want to patent. It is done to determine if your idea or invention claim is disclosed in the existing patents, patent applications, and non-patent literature from around the world. In other words, it is done to find out whether the invention (or an obvious precursor) is already written about somewhere in the world.

Search Types

This type of searching includes all appropriate search types. There are five search types. The keyword, classification, structure, sequence, and image types. Our expert uses all types as appropriate.

Note: All prior art search patent services at our firm include keyword and classification type searching. All searches where images or drawings are available also include an image searching.

Important TIP. Proper searching greatly enhances good patent specification writing. Searching also guides writing claims to improve the protection they provide for your invention. Proper searching can reduce or eliminate potential rejections and objections. Thus, it can save you money.

What is a Novelty or Patentability Search?

Similar to the prior art search, this is a search to find out whether an invention is new and patentable. Usually done before the inventor files a patent application. Always recommended before applying for protection. As above, Novelty and Patentability Searches include all appropriate search types.

Important TIP: Once an application is submitted, you cannot add any “new matter” to it. You must file a new application or a continuation in part (CIP) if you need to add any drawings or description to support your claims after your initial filing.

What is New Matter in a patent application?


 New Matter Carson Patents Logo icon with text. New Matter is content not found in either the written description or drawings, involving a departure from or an addition to the original disclosure. It cannot be added to the application even if supported by a supplemental oath or declaration. New matter can only be shown or claimed in a separate application.

Disclosures to patent practitioners are covered by client controlled privilege. We ensure confidentiality of our services by doing all prior art searching, application writing, filing, and patent prosecution in-house. Newly filed applications are treated as confidential for about 18 months by patent offices around the world, but then they are published. Issued patents are public.
