First of all, you would have to think of the goal of the patent search? What do you want to accomplish? In this video I will focus on two very common types of search:

1) The Prior Art Search
2) The Freedom To Operate Search

In the prior art search your goal is typically to find out, whether the invention of an inventor is actually new or whether you can attack a patent of a competitor based on lack of novelty or lack of inventive step. You can keep the search quite narrow – targeted to the exact key concept of the invention or the patent.

Let’s use an example. In this example I use a patent database called TotalPatent – many databases have a very similar scope of functionality. It is just the tool that we happen to use.

In the video I explain in a detailed screencast, how to do a basic patent search.

Let’s look at the other type of search that I wanted to explain - the Freedom-To-Operate (FTO) Search. Assume that you are a manufacturer for hair dryers.You are launching a new product and you want to find out, whether you are potentially infringing any patents of competitors with this new product.

In this type of search you do not want to limit your search too much with certain keywords. With the limitation to keywords, you might easily overlook patent of competitors, that are very relevant but use a different language or different wording. You can limit the search to the countries, where your products are sold. Normally, you can limit the search for patents that were filed in the last 21 years, since there is only a one-year priority term and a maximum duration of patent of 20 years. Sometimes, you can limit the search to your most important competitors. Or you can limit the search to certain technical fields by IPC classes. After you have determined the search strategy, you would have to look at each and every found patent and determine the following:

- Is the patent or patent application still in force?
- Does my new product fall under the independent claims?

In this step, I typically consult the original patent registry to make sure the legal status of the patent or patent application. Then, if it is in force, I look that the independent claims and see, whether there is a chance, whether my new product would fall under these claims.

If I see that my product would fall under these claims, I can then do a prior art search for this patent and find out, whether I can attack this patent based on lack of novelty or lack of inventive step. You see that such a Freedom-To-Operate (FTO) Search can be very elaborate and therefore very costly.

In this video I could barely scratch the surface of what a patent search is all about. If you liked this video or want to know more about certain aspects of patent search, let me know below this video in the comments. Subscribe to my channel.

I know that enlisting the help of a patent attorney may seem costly. However, I think it is worth every penny. And as always: reap your ideas!
