A General View of Patents

A patent is an exclusive set of legal rights granted to an inventor or patentee by the government or the statutory body. The patent helps the inventor stop a third person from unauthorized making, using and selling the application. The duration of the validity of a patent in the USA is for 20 years post submission of application for patent grant. This term of validity differs accordingly in different countries.

Intellectual property law is equally applicable and incorporates patents, trademarks, and copyrights. An invention must be novel, non-obvious and commercially exploitable in order to win a patent. The three primary types of patents are as below:

  • Utility Patents– They protect the invention or product with a specific function.
  • Design Patents– They protect the decorative part of a functional item.

A patent application is a combination of Claims, Drawings and Description of the Invention.

Patent Search Techniques and Tips to be remembered:

The following things should be kept in mind while doing a patent search:

Learn about the search tools

The features of each and every database are unique and different. As a searcher, you must go ahead and learn about the database in detail by taking the help of the Help Section in any database.

Use multiple keywords

Always do a search with a maximum possible combination of keywords for your intended invention or product. This is because similar products can have different nomenclatures. So make your brain work harder to do the search with all possible keywords for an invention.

Understand the Classification System

Inventions that are registered with the US Patent System are classified into Classes and Sub-classes. Individual inventions have their own numbers. To get a more specific result, an applicant or searcher should search for his/her invention within the target class. This takes time to learn. For both Europe and the U.S., there is a classification system but for other countries the systems are different. All those applicants who wish to file a patent application in different countries should learn the patent classification system of those countries in order to do a patent search.

Search probable Patent Owner

For all those applicants who have an idea about their probable competitors can conduct a patent search by the competitor’s name. This will help that applicant or you to get an idea of what the competitors are doing and simultaneously search for concepts that can have similarities to your invention. Further, it will also help you determine any possible patent infringement if applicable.

Take help of Paid Database

You must use proper patent search techniques on the paid version of databases instead of only sticking to the free versions. These databases make the search easier for you by automatically generating similar keywords. Also, you can compare the results of both paid and free databases. The results from multiple databases are complex to segregate. A Patent is considered not valid if you are unable to renew it.  But, an invention is always a prior-art and these results altogether affect the characteristics of the invention that you want a Patent for.

Citation Search

If you get to find a patent that has similarities to your invention, you should further dig down to find out what the patent cites. This may eventually lead to the discovery of more such similar patents to that of your invention.

Boolean Search

The way you solve problems by the Boolean method can be similarly applied while searching for patents. Combine two or more keywords or search phrases with AND, OR or NOT to get varied results.

Search by Instance

A few search engines enable you to use a particular Patent as an example. Thus, the search engine can use that Patent to gather information about similar documents.

Group the Search Outcomes

The search engine allows you to group together the documents which are related to similar fields/themes. Although, it is possible that some unwanted documents might also enter your cluster.

Search from every possible angle

Once you are completed with the search of related Patents with possible patent search techniques, you must again look for similar outcomes but with a different vision. As it helps to gain the information missed at the first search.

To organize the Search Results
