5 Frequent Pitfalls of Freedom To Operate Analyses

Whether you refer to it as a Freedom To Operate (FTO) search, Clearance search, or an Infringement search, this type of patent search is an integral part of the innovation process. An FTO search, among other things, will help you assess your innovation and aid in determining where to focus research and development efforts as you prepare to bring your product to market. At a high level, this type of patent search allows you or your legal counsel to determine your risks of infringing on an existing valid and in-force patent and whether you have the freedom to operate, or clearance, in the given market in which you plan to introduce your product or service.

About Us

For nearly 25 years, our team, as a highly reliable patent search specialist firm, has consistently raised the bar when it comes to patent search and analysis services. Our quest for excellence began in 2004 when we combined manual searching and the use of online tools. Then we provided more complete results, quicker than our competitors, by searching patent and non-patent literature (NPL) from multiple sources. After that, the team introduced full-text native language searching across all technology areas. Realizing these efforts still weren’t enough, we applied business management, personnel development, and the strategic use of database tools to deliver even more consistent results and improved customer service.

With Ensemble IP, we have pioneered the patent search and analysis firm by combining humans and AI, which will deliver lasting innovations in patent search.

Ensemble IP Delivers More

We, as the best patent search firm in the world, provide more complete results by putting the best AI tools in the hands of skilled technical experts, performing full-text native language searching, and manual searching at libraries.

A holistic search requires a new paradigm.

Patent practitioners have the critical role of delivering informed legal advice to innovative companies who are spending immense capital on intellectual property. No searcher can assure complete prior art searches in any language. The industry’s singular reliance on the same tools and methods is a major disservice to patent attorneys and to their clients. Ensemble IP is introducing a new paradigm that combines the best of human searchers and advanced AI tools to deliver unparalleled results.


Ensemble IP subscribes to every important patent and scientific literature database. When conducting a patent search, we do not charge you for access to these systems unless they are unavailable to us by subscription.
Patent Publications
Ensemble IP’s patent analysts have digital access to patents and publications across 95 patenting authorities that include a mixture of full-text, machine-translated full-text, and bibliographic patent document collections.
Scientific and Technical Publications
We access the vast universe of non-patent literature sources, including resources from CAS, Elsevier, Dialog, Clarivate, ProQuest, IEEE, ACM,, and many others.
