Your CEO: “Why are we spending so much on patents?” Your CFO: “Do we have a financial model for this spend?” The path forward isn’t clear. Now what? In this case study, we explore how we helped a high-technology, startup client model the value of their patent portfolio and patent strategy.

Patents provide value in different ways depending on how you use them

In one of our previous articles, we discussed how patents generate value for companies in several different ways. In this particular case, our client had been running a patent program for a few years and had built a patent portfolio for defensive purposes. Their goal had been to mitigate the risk of patent assertion from large companies in, and outside, of their ecosystem, see Figure 1.

The costs of the program were increasing, and the executives wanted a deeper understanding of the financial underpinnings of the patent strategy. The program costs were relatively easy to calculate. But calculating the expected return, or value, of the strategy and portfolio, was more of a challenge. We helped the client to assess the risk from their ecosystem and to model and value their current patent portfolio and patent strategy. In the end, the client used the model and the strategy to better articulate the value of their program and helped the organization unite around the company’s patent strategy.

Our client had built their patent program primarily around a counter-assertion strategy, and their intended use of their patents was mainly for defensive purposes. Therefore, we focused on modeling the value of patent risk mitigation through counter-assertion. Note: we did not try to model the sources of value from the patent portfolio.

How do you assess your patent risk?

First, we needed to better understand our client’s patent risk. The client was vulnerable to patents of operating companies within their ecosystem, large corporate asserters outside of it, and NPEs. Their patent strategy focused on mitigating the bigger risks. Figures 2 and 3 illustrate the basis for analyzing and mitigating patent risks.

First, we had to identify likely patent asserters within and outside of our client’s ecosystem. Figure 2 illustrates a simplified view of an ecosystem. We reviewed all the client’s suppliers, customers, partners, and competitors for potential threats. We assigned each company a label of either high- or low-risk and went on to assess the specific risk of each high-risk company. Figure 3 illustrates how a counter assertion by our client could change the dynamic in an assertion by Company A. Specifically, Company A’s revenues would be at risk due to their infringement of our client’s patents.

Modeling patent risk to determine expected value from your patents

After mapping the key sources of patent risk, the client wanted to approximate the counter-assertion potential of their portfolio. To do this, we looked into each high-risk company and asked the questions: what is the present value of the expected patent risk for this company? And how much could we reduce that risk by using our current patent portfolio for counter-assertion?

To answer the first question, we estimated the likelihood of an assertion as well as the cost and expected time frame of that assertion. This allowed us to list and compare all the companies based on expected risk.

To answer the second question, for this client, we used class codes as a proxy for potential patent infringement. This required analysis of the concentration and overlap of class codes of both the client and each high-risk company. Taking one example, our client’s portfolio was concentrated in five IPC class codes. Looking at OpCo 1 (see Table 1), we looked at the overlap of OpCo 1’s patents with our client’s five class codes to identify a higher chance of OpCo 1 infringing our client’s patents. The analysis was repeated in the other direction to look at the concentration of OpCo 1’s patents to assess our client’s risk of infringement. The class code assumptions are important and may need to be further tested depending on the situation. More sophisticated analyses can be performed for more refined results, e.g. claim-level analysis, machine learning-based similarity analysis, etc.

Table 1 illustrates how this can be applied. Take OpCo1 as an example. If we follow OpCo1’s row in Table 1 from left to right, you can see how we arrived at the value of using our client’s patent portfolio for counter-assertion against OpCo1.


In the case that our client didn’t have any patents to use for counter-assertion, we estimated that they would have to pay $100 million in royalties if OpCo1 were to assert their patents. The probability of an assertion was estimated at 5%, resulting in an expected risk of ($100 million x 5%) $5 million. We expected a dispute with OpCo1 to take place five years down the road, so we had to discount the expected risk to get to a present value. When we did that, we got a present value of $3 million for the patent risk from OpCo1. If OpCo1 were to/decided to assert their patents against our client, we assumed that our client’s patent portfolio could be used for counter-assertion and that it would reduce the expected payment by 75%. That 75% translated into expected savings of $2.6 million due to our client’s patent portfolio. The same calculation was repeated for all the high-risk companies we had identified in the previous phase (OpCo 1-9).
The expected savings totaled $22.6 million, and we added a total of $9.5 million for other risk reduction from Ecosystem Players and General Deterrence. Now the client had a number to reflect the value of their patent portfolio based on its use for counter-assertion.

Using a model that examined both patent risk and expected reduction from the patent program and portfolio allowed the client’s IP department to generate a number that showed the value of their efforts. In turn, this enabled the executive team to grasp the return on investment (ROI) of the patent strategy. Our client now had a tool to use for making decisions on how to mitigate patent risk and where to spend money to build their patent portfolio.


All high-technology startups have patent risk, and they should assess that risk to gain insight into what strategies might provide them with the best-expected return from their patent strategy. Creating a model to articulate the value of your strategy will support your decision-making and help you communicate the value of different strategic options internally. It may also provide clearer guidance as to what kind of ROI your patent team is generating.
