A patentability search is conducted to determine if an invention meets the requirements of

  • Novelty;
  • Usefulness (industrial applicability); and
  • Non-obviousness (inventive step).

Novelty Searches/ Patentability Searches are asked for to gather a hoard of technical information or “prior-art” pertinent to the invention to assess its patentability based on novelty and non-obviousness/inventive step.  This search is usually performed prior to the preparation of the patent application.

Invalidity/Validity Searches are exhaustive Prior Art Searches conducted to either validate the claims made by a patent or to invalidate one or more claims of a competitor’s patent.

It is a confirmation to the applicant that the patent can withstand litigation and its validity is undisputable, and no claim can be raised on the basis of prior public use or a prior invention.

For each search, we provide a Claim chart representation of each Prior Art, wherein we define each element of the claim w.r.t. its functioning as mentioned in its description. A thorough and detailed analysis of all references is provided which includes feature to feature mapping.
