Patentability Searching Basics.

How to start and do a prior art search – patent searching basics.

A basic Patent Search is researching various data sources to determine if there is prior art that discloses your invention. Prior art is existing patents, patent applications, and publications (non-patent literature). It is found around the world. Prior art is those existing documents that are similar to your invention, or describe your invention.

What you need?

You will need three things for input into the search engines to do a patent search. You will need the following:

  • Description
  • Keywords
  • Classification

Description.

The place to start a patent search is with the description of the invention. A description of the invention that is just a simple sentence or two is the easiest to work with. A concise description is easier to work with. This is because what you will need for actual searching in databases is just the right few keywords and the right classification(s) for the invention. You are looking to locate all the existing products and processes that are the most similar to our invention.

Keywords.

The description is used to develop a good set of keywords to use for searching. The best keywords to use are those terms and phrases about the invention and its field of use that describe it most accurately and completely. A good concise description will be simpler to use. The concise description likely already has many if not all of the keywords that you will need to start a search.

Classification.

The final piece to the input for a patent search is the classification. The classification system to use is the CPC Scheme (find it on the USPTO website). The CPC is the Cooperative Patent Classification system. The CPC (like all classification systems) categorizes inventions into classes. The idea is that all the other inventions that are like your invention will be in the same class(es). Searching by class is essential to a complete patent search.

TIP: If you don’t know or can’t find the class(es) for your invention, one place to start is the class(es) of the patents that you find with keyword searching. After you find a patent similar to your invention, you can use that patents classification as a starting point for your invention.

Places to Search. Where to Search. What Data Sources to Search.

You should search the following data sources, at a minimum. The more places searched the more complete the search. However, the following list of sources will give you a good start. And, quite likely, more prior art (existing stuff like yours) than you were expecting.

  • United States Patent and Trademark Office (USPTO) – uspto.gov
  • European Patent Office (EPO) – epo.org
  • World Intellectual Property Organization (WIPO) – wipo.int
  • Google Patents – patents.google.com

Steps to Patent Searching for Prior Art and Conducting the Patent Database Search.

Step 1: Use the keywords to Search the USPTO or Google Patents databases. You are looking for products or processes that are similar to or describe your invention.

Step 2: After the initial search. Review the Results. – Assess, Evaluate, Refine keywords and classification(s) to narrow the results. You are looking for only those products or processes that are the most similar to your invention. The more specific the keywords are the better the results will be.

Step 3: Use refined keywords and classification(s) for Full Search of all data sources to be searched. An exhaustive search would include databases from many countries in many languages all over the planet. At a minimum, the databases available at the USPTO, the EPO, WIPO, and Google Patents should be searched.

What you are Searching and Looking for in the results of the search.

There are two things that you are looking for in the information that you discover in the databases.

Firstly, whether the invention is described in the prior art. Is your invention already available, or described in the existing patents, patent applications, and publications (prior art) around the world?

Secondly, whether the claims of the invention are novel. Is your invention new, or already described in the prior art (the existing patents, patent applications, and publications)?


Patent Practitioner Help Recommended.

Disclaimer, nothing in this article constitutes legal advice. Prior Art searching and patentability determinations are time consuming and complex tasks. Importantly, all patents, patent applications, and non patent literature (everything in academia and the internet) from around the world need to be examined and considered in an exhaustive search. Further, the expert search needs to include any and all other related fields of potential use that may be applicable with the idea or invention.

We highly recommend two things. Firstly, that you do a search with these basics. Secondly, that you contact a professional patent practitioner for expert help.

Important Note. Proper searching greatly enhances good patent specification writing. Thus, proper searching can reduce or eliminate potential rejections and objections. Thus, it can save you money.
