Prior Art Search

An innovation may be patentable, if the work is new, useful and non-obvious to others in the same area of research.  It is necessary to identify prior art (i.e., the body of knowledge that already exists on a subject) to understand what has already been done in the field and to determine whether the innovation meets the requirements of being new and non-obvious before you commit the resources necessary to obtain a patent.

A basic patent search involves searching publicly available patent databases and scientific literature, using keywords that are closely related to the innovation.  The prior art search provides information about whether any other similar innovations exist and where an innovation fits within a broad field of study, which can be very helpful when drafting a patent application.

Our team of experts has gone further than these; we specialized in our customized information databases and have more than 100 consultant experts to work with in these technological areas:

Infringement Analysis

It is important to you at any point during the product life cycle to protect your product/s and clear it for marketing and/or sales without worrying for any potential infringements.

We provide Infringement Analysis (sometimes called a Product Clearance Search), to demonstrate that a proposed product does not infringe any in-force patents, trademarks or any forms of IP. A patent infringement analysis determines whether a claim in a patent literally “reads on” an accused infringer’s device or process, or covers the allegedly infringing device under the doctrine of equivalents.

Furthermore, a Freedom to Operate Search extends the results of a Product Clearance Search or Patent Infringement Search to include expired patents and other publicly available documents, which provide a safe harbor for a product or technology. Such analysis becomes vital to stay competitive in your business, both today and tomorrow.

Validity/Invalidity Analysis

A “Validity/Invalidity Analysis” is a form of IP search and analysis process done after an IP right was granted or issued.  The purpose of a validity (or invalidity) search is to seek prior art so that a patent can be declared invalid.  This same methodology can also be applied on revoking the trademark registration. Such strategy can be seen in the alleged defendant counter-proofing to invalid the patent owner via other pre-existing “art”.

Prior to buying, selling, asserting, or licensing your patent or trademark, it is highly recommended to determine its strength and enforceability by conducting a Validity Search and Analysis.  Knowing whether the patent or trademark can withstand an attack on validity grounds allows you to take a stronger, better-informed negotiating stand. Contrary, a patent infringement defendant will challenge the validity of a patent during litigation.  When confronted by such allegations, proof of invalidity based on prior art is often the line of defence.
