Patent Due Diligence

About the service

The process of carefully analyzing a company's patent portfolio is called patent due diligence. It audits the quantity and the quality of IP assets owned by or licensed to a company, business, or individual. In other words, Patent due diligence is a method of closely reviewing a patent portfolio and status. A strategy in technology development and patent portfolio management should include due diligence review. Such review would evaluate the intellectual property (IP) of others to gain "freedom to operate" in a given technology field. Due diligence may also occur in evaluating patent portfolios, such as in a corporate transaction that may involve patent acquisition or the sale of a company.


To identify promising IP assets for Licensing or Acquisition activities, Effectual Services collaborates closely with their clients to ranking these patent based on our proprietary or client specified ranking models. The output of such a scoring model eventually ranks patents as High, Medium and Low. The ranking methodology can be of two types –

Step 1

Semi‐automated solution

We understand the need of optimizing costs for our clients and of delivering maximum value to them. We have developed a scoring system for identifying key patents from a large portfolio, based on certain parameters. This scoring system takes into account both objective and subjective parameters such as forward citation, number of independent claims, claim length, detect ability of overlap, market segment and size, etc.

Step 2

Manual solution

Depending on the client’s needs, we can also provide an entirely manual approach for ranking patents analysis, wherein the scoring is based on a completely manual analysis. Such an analysis does include all the parameters used in semi‐automated approach, but also the analysis is extended to more subjective parameters, such as, remaining life, number of foreign family members, availability of alive family member, number of office action responses, etc.

Patent bucketing and ranking is a strategic process that involves categorizing a company's patent portfolio into specific technology segments and then assessing the patents within those segments to determine their value and potential.

Patent bucketing and ranking are essential for companies with large patent portfolios to effectively manage their intellectual property assets. It helps identify high-value patents for licensing or strategic partnerships while minimizing maintenance costs on low-value patents.

Patent bucketing involves creating a comprehensive taxonomy that classifies patents into specific technology areas. This taxonomy serves as a framework for organizing and analyzing patents based on their technological relevance.

Patent ranking involves assessing the strength and value of patents within specific technology segments. This assessment can be done using either a semi-automated approach or a manual analysis, depending on the client's needs.

The benefits include better portfolio management, cost reduction, identification of valuable patents for licensing or acquisition, and improved decision-making regarding intellectual property assets.

A semi-automated ranking approach uses predefined criteria and algorithms to assess patent strength. It combines both objective and subjective parameters to generate rankings efficiently.

A manual ranking approach is suitable when a more in-depth and nuanced analysis of patents is required. It involves human experts evaluating patents based on a broader range of criteria, including subjective factors.
