  • What is the importance of patent classification codes?

    A patent classification is a system for examiners of patent offices or other people to categorize (code) documents, such as published patent applications, according to the technical features of their content. Patent classifications make it feasible to search quickly for documents about earlier disclosures similar to or related to the invention for which a patent is applied for, and to track technological trends in patent applications. Searches based on patent classifications can identify documents of different languages by using the codes (classes) of the system, rather than words.

  • How does the Patent landscape report benefit research and development?

    A technology landscape will guide and help to develop business and patent filing strategies. Understanding the technology trends through landscape reports facilitate in analyzing the business intelligence that can be complex and difficult to understand. Patent activity reflects technology investments by patent applicants and provides the data on:

    • Organizations exist in the space
    • Patent portfolio and corresponding position of the organizations
    • Filing history of the organizations in different jurisdictions
    • Strength of patent portfolio within the technology space
    • Emerging vs. Well established companies within the space
    • Monitor the markets of interest and determine the list of expired and inactive patents
    • Learn about the current and future competitors
    • Identify technology gaps in research & development
    • Determine which of your patents are most valuable

    Prometheus IP delivers reports that can facilitates the client’s research better by reporting past, and current trends in technology and research.

  • Why Patent Watch/Alert is important?

    The Patent watch/Alert service is provided to update our clients on the new patent filings in the specific field of technology. The monitoring is performed based on the specific technology or specific to any organization or by a particular inventor(s). Patent watch service helps the companies to be aware of the records of the new inventions in a particular field so that they would be able to take better business decisions.

  • How frequently do you provide Patent Watch Reports?

    • Client specific duration


  • What is Inventor & Assignee based search?

    Finding patents filed in the name of a specific individual or an applicant/assignee may help in identifying the work being done by the applicant/assignee.

    The patent databases have options for conducting inventor and assignee/applicant based search (this is where to find company information) searching:

    • Espacenet – Advanced Search — Input: Applicants and Inventors
    • Google Patents – Advanced Search — Input: Applicants and Inventors
    • From the U.S. Patent and Trademark Office, for both granted and applications files — Input: Applicants and Inventors (in the pull-down menu)
  • What is citation analysis?

    Patent citations are the references defining technology already known within either patents or other scientific on patent literature cited by the present patent. They are very much similar to the citations in any research paper.

    Patent citation analysis is an important technique which can be used to study the evaluation of science and technology. The basic principle behind its use is that papers or patents cited as prior art by many later patents tend to contain important ideas upon which numerous inventions have been built. This does not mean that every important document is highly cited, or that every highly cited document is important. However, numerous validation studies have revealed the existence of a strong positive relationship between citations has a technological importance.

  • What is patent clustering in state-of-art search and why it is important?

    Patent clustering creates groups of similar patents using fielded data. Various classification systems produce a standardized code that can be used as a means of organizing documents that share a similar coding structure. Patents which share a high percentage of codes in common are likely to be similar. Furthermore, patent clustering facilitates in organizing a large number of patents in to groups and subgroups.

  • What is the claim chart and where it is required?

    A patent claim chart is commonly used in U.S. Patent infringement litigation and can be in tabular (for evidence of use) or graphical formats. The claim chart is basically a visualization of all of the information analyzed in a patent claim. The purpose of a claim chart is to determine if there is any infringement activity.

    There are many different use cases for claim charts. Simply put, a claim chart is a tabular or graphical presentation that breaks a patent claim into its constituent elements, or limitations. For each element, evidences of use or prior art is presented. The goal of a claim chart is to systematically present the mapping between each claim limitation and the evidences of use, prior art, intent, etc.

  • What is prosecution analysis?

    Patent prosecution entails arguing for the patentability of the invented machines, devices, methods or systems. This starts with applying for and successfully receiving a patent from the appropriate government agencies. It also involves asserting the novelty of your patent through the submission of supplementary materials, including design blueprints and detailed instructions.

    Some of the Salient Features of our Patent Prosecution Analysis include:

    • Technical Analysis of Office Actions
    • Technical Analysis of Cited Prior Art references
    • Analyzing Examiner objections and Applicant counter arguments to understand inventive step.
  • How to identify competitor technologies?

    Technology is the practical use of scientific information. To stay ahead of competition, organizations have to constantly update their existing processes, products and technology. One strategy to improve these is to make use of existing available technology through searching patent information to explore the patent technology so that the patent literature can become a part of a company’s competitive strategy.

  • What is white space analysis?

    White Space is the area with little or no patenting activity. White Space designates a methodology that helps in analyzing a methodology that identifies the absence of patents in a particular technology area as a primary driver of innovation and decision-making.

  • What is evidence of use search?

    Evidence of Use search (EOU) Search is performed to help patent owners identify potentially infringing products in the marketplace. The purpose of EOU search is to identify products or processes in the market which are likely to infringe the patent holder’s patent or even patent applications.

    The evidence gathering or Evidence of Use (EoU) generation approach varies with the type of claim. In the case of method and system claims, one generally relies more on web sources, product testing snapshots, and user manuals for gathering necessary evidences to generate the EoU map. However, in the case of CRM/CPP claims (computer-readable media claims), it happens quite a few times that one is not able to gather sufficient evidences from web sources, product testing snapshots, and user manuals. Thus, to establish a high value EoU map, detailed source code analysis and reverse engineering techniques for gathering evidences becomes imperative.

  • How design search is executed?



    • Identifying one or more keywords and its synonymous related to the specific designs of desired domain.
    • Conducting search on different design patent databases using one or more combinations of identified keywords.


    • Identifying different design classifications
    • Conducting search on different design patent databases using one or more combinations of identified design class codes.


    • Searching for identical images by uploading the reference image file in to the database. (EX. Google Images)
