Patent Search
  • Novelty/Patentability Search: It is performed before preparing a patent application in order to determine whether or not the invention will be patentable based on the grounds of novelty, non-obviousness and utility which are interpreted differently in different legislatures and judiciary systems of different countries. A good patentability assessment ensures that the patent will not be rejected due to patentability criteria.

  • Patentability Search (excluding Novelty): It provides information whether an invention is patentable or not by analyzing the claims of a patent application so that an applicant can suitably amend his application.

  • Non-Patent Literature Search: It is a search in any documents that are not patents. It is found in both national and international databases and is often used when describing portions of a patent search that review web sites, technical journals and databases, textbooks, etc.

  • State-of The Art Search: It is a broad search on everything that has been done in a given art. It identifies current level of technical development in a particular field. It is useful for a company if it is considering entering into a particular domain of art. State of the art search results can provide a basis for making critical market decisions. These results can also be used as a navigation framework for product and process design.

  • Validity/Invalidity Search: It is practically equivalent to an extensive or comprehensive patentability search. The purpose of this search is to determine whether a patent already obtained on an invention is valid or not. Here the pre existing patents serve as disclosure. The sole idea is to find prior art that is relevant in terms of the validity of the CLAIMS of the subject patent. Though the interest for validity search is for the issued patent, filing date (patent term) holds a very important aspect in the validity search process.
  • Freedom to Operate Search: It identifies potential patent barriers in order to practice or use an invention orcommercialize the products or technologies. The search involves finding and understanding the claims of third-party’s in-force valid patents to determine whether the claims are infringing the claims of the patent of interest. Search is conducted as a due diligence effort to avoid infringement.
  • Patent Infringement Search: It is practiced in order to demonstrate the technical advancement in contrary to the technology in question. In this, claims are analyzed by studying all of the relevant patent documents and are tested to find out whether they describe the accused infringement. Each element of the claim must be studied thoroughly in order to show literal patent infringement.
  • Bibliographic Search:  It provides the bibliographic status and complete bibliographic data of a patent application. The search terms include Inventor name and Applicant name. Different classification symbols are used for different classes of patents.

  • Patent Watch Search: It is about continuous monitoring of newly issued patents on a periodic basis in the technological field of interest. Patent watch is performed for corporations in patent-based businesses (invention oriented) to keep the records on the new inventions coming in a particular field of technology as well as to keep a track of the prosecution and litigation details.
  • Patent Family Search: It identifies the global status of an invention for its protection and indicates the existence of a similar corresponding patent of the same family. It provides bibliographic details of a desired patent of a patent family and helps in estimating the importance of an invention.
  • Legal Status Search: It tells us whether a patent application has been published or granted. It further tells us whether a patent is in force and the complete legal status of the application in a particular country on a given date. It helps in decision making, licensing agreements, assignments and exploitation of an invention. It assists in preventing patent infringements and payment of license fees for lapsed patents. It also provides the application number and other necessary details of a particular patent.
  • English Equivalent Patent Search: It helps in identifying English language equivalent translation for a Non-English patent by finding a patent family member in English language.
