Freedom To Operate Search - VPN Case Study

Imagine you’ve come up with a fantastic idea that has a lot of potential. You begin working on it with the product development team, investing millions of dollars in research and development. You secure various features of your product by obtaining patents on them after completing a patentability search since you understand the value of having good IP. Your product is now ready for market, but there remains a major hurdle.

You made one serious error during the process, which could cost you the launch and lead to unnecessary lawsuits. You might wonder what went wrong. You relied on patentability search until the very end, then switched to a Freedom to Operate search just before the product’s commercialization.

You discovered that you cannot launch the product using the Freedom to Operate search. Multiple patents are infringed by your product, including patents held by your competitors. Furthermore, you have already spent millions on patent registration and product development, so cancelling the product launch is not an option.

In this case, you are left with only two options:

  • License or buy the relevant patents

  • Invalidate the relevant patents.

These solutions might work, but they’ll cost you at least thousands of dollars, and there’s no guarantee that they’ll keep you out of litigation.

This problem can easily be avoided by doing Freedom to Operate search early in the product development process. Conducting Freedom to Operate search ahead of time has additional advantages. It could help you identify and avoid most patent-related barriers during the development phase.

In an earlier post, we shared the cases that highlights the benefits of Freedom to operate search and thorough analysis, which may assist other corporations or enterprises in marketing their products in different countries without concern of infringing on any valid patent or patent application under prosecution.

Today, we will share with you one freedom to operate- VPN case handled by Wissen research.
