Patent Searches

A patentability search is probably the most valuable tool you can have during the initial stages of invention development. Our searches are performed by a registered U.S. patent agent and are never sub-contracted out. Standard patentability searches include a thorough search of U.S. patents and published applications, and a foreign patent documents.

The results of a patentability search will assist you in the decision of which type of patent application should be filed or if more work is needed on your invention.

If required, a formal legal opinion on patentability can be prepared.


 Patentability Search 
A standard patentability search is intended to locate patents which help you in determining the patentability, novelty, and non-obviousness of your invention. If feasible, a search will include both the utility and design features of your invention. This provides you with the option of pursuing both design and utility patent protection. This common search finds the most related prior-art patents pertinent to the patentability of your invention. Typically, 5-15 prior-art patents are found and may serve as a basis for a patentability opinion, and are submitted in an invention disclosure statement with your patent applications filing.

 Validity Search 
A validity search is designed to locate prior art patents which predates the effective filing date of the patent being investigated and which may be used to challenge the validity of the claims in that patent. A validity search can serves as a basis for a legal opinion against infringement or as due diligence prior to selling or license a patent. File wrappers can be obtained and reviewed when authorized.

 Infringement Search 
An infringement search normally involves the careful review of unexpired U.S. patents to locate claims which read on the invention at issue. Additionally, analogous art areas are also investigated and supplied to assist you to address the issue of contributory infringement.

 Right to Use/Clearance Search 
A right to use or clearance search normally includes a complete infringement search through unexpired U.S. patents which could present a possible infringement problem with respect to the invention at issue, and a very limited validity search through both expired and unexpired patents and publications which might be used to invalidate any patents that might cause an infringement situation. Another reason in locating expired patents is to provide proof that an invention is already in the public domain.

 Collection Search 
A collection search will normally involve the collecting of ALL U.S. patents relating to a particular invention or subject matter. Any patent that is relevant to the invention will be included. This type of search can produce from 20 to 300 patents, depending on the scope of the invention. This search can be limited by specifying certain years, limiting the number of located patents, specifying assignees or inventors, or providing more specific information on the invention.

 State of the Art Search 
A state of the art search is directed to finding patents that represents the general state of art (technology) to a particular type of invention or subject matter. A state of the art search is similar to a collection search but the searcher is allowed judgment in selecting patents. This type of search normally locates patents from the last 15 to 20 years, including published patent applications.

 Technical Literature Search 
A technical literature search involves the review non-patent documents from online computer databases. The non-patent documents may include magazines, newspapers, journals, and other documents.

 Assignment/Patentee Search 
An assignment search discovers patents that were assigned at issue or after issue to a particular company or entity. An abstract of title can be obtained for a patent, at an additional charge. A patentee search discovers patents that were invented by a particular person.

 Trademark Search 
A trademark search involves the review of trademarks having a similar mark, and in similar goods and services, as your product name. Federal and state trademarks can be reviewed.
